+= How to contribute to the reference
+
+The Spring Framework reference now uses https://asciidoctor.org/[asciidoctor]. This
+document describes how to contribute documentation updates.
+
+== Building with Gradle
+
+You can build the documentation using gradle using the `reference` task. For example, from
+the project root execute the following command:
+
+	./gradlew reference
+
+the output will be available at `spring-framework/build/reference/htmlsingle/index.html`
+
+== Live editing
+
+One of the nice features about using asciidoctor is the support for live editing.
+
+You will find a Guardfile already present at `spring-framework/src/asciidoc/Guardfile`.
+Make sure first to follow the setup instructions within the
+https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/[Editing AsciiDoc with Live Preview]
+document. Once you have done that, there are additional gems to install to make it work
+(assuming that you are using http://livereload.com/[LiveReload]):
+
+	gem install guard-rspec guard-livereload
+
+When running `guard start` within the `src/asciidoc/` folder, any changes to the
+`src/asciidoc/index.adoc` file will automatically be written at
+`src/asciidoc/build/index.html`.
+
+== Troubleshooting
+
+* If you are using LiveReload, make sure to select _Allow access to file URLs_ in the
+  LiveEdit plugin options of your browser.
+* The icon used to enable _LiveReload_ can be a bit confusing. The dot is empty when it is
+  disabled and full when the plugin is active. Make sure to enable it on the tab
+  displaying the `index.html` file.
+* Ensure you are _not_ running guard start at all as two instances could not run at the
+  same time. To exit a current session in a clean way, just type e in the shell.
+
+== Documentation notes
+
+Some notes on documentation
+
+* Documentation is wrapped at 90 chars, ensure that you manually wrap your edits
+* Tabs are used for indentation, do not use spaces
+* Follow the existing style when inserting `source` blocks
+* https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/[Asciidoctor Quick Reference]
+* https://asciidoctor.org/docs/user-manual/[Asciidoctor Manual]
+* https://asciidoctor.org/docs/asciidoc-writers-guide/[Asciidoctor Writers Guide]

+### Understand the basics
 
-### Code of Conduct
+Not sure what a pull request is, or how to submit one? Take a look at GitHub's
+excellent [help documentation][] first.
 
-This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc).
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
+### Search Stack Overflow first; discuss if necessary
 
-### How to Contribute
+If you're unsure why something isn't working or wondering if there is a better
+way of doing it please check on Stack Overflow first and if necessary start
+a discussion. This is the official list of
+[Spring project tags](https://spring.io/questions). In short the issue tracker
+should be used to report issues and make feature requests.
 
-#### Discuss
+### Search JIRA; create an issue if necessary
 
-If you have a question, check StackOverflow using
-[this list of tags](https://spring.io/questions), organized by Spring project.
-Find an existing discussion or start a new one if necessary.
+Is there already an issue that addresses your concern? Do a bit of searching
+in our [JIRA issue tracker][] to see if you can find something similar. If you
+do not find something similar, please create a new JIRA issue before submitting
+a pull request unless the change is truly trivial -- for example: typo fixes,
+removing compiler warnings, etc.
 
-If you suspect an issue, perform a search in the
-[Github issue tracker](https://github.com/spring-projects/spring-framework/issues), using a few different keywords.
-When you find related issues and discussions, prior or current, it helps you to learn and
-it helps us to make a decision.
+### Sign the Individual Contributor License Agreement (ICLA)
 
-#### Create a Ticket
+If you have not previously done so, please fill out and submit the
+[Spring ICLA form][]. You'll receive a token when this process is complete.
+Keep track of this; you may be asked for it later!
 
-Reporting an issue or making a feature request is a great way to contribute. Your feedback
-and the conversations that result from it provide a continuous flow of ideas. 
+Note that emailing/postal mailing a signed copy is _not_ necessary. Submission
+of the web form is all that is required.
 
-Before you create a ticket, please take the time to [research first](#discuss).
+Once you've completed the web form, simply add the following in a comment on
+your pull request:
 
-If creating a ticket after a discussion on StackOverflow, please provide a self-sufficient description in the ticket, independent of the details on StackOverview. We understand this is extra work but the issue tracker is an important place of record for design discussions and decisions that can often be referenced long after the fix version, for example to revisit decisions, to understand the origin of a feature, and so on.
+    I have signed and agree to the terms of the Spring Individual Contributor
+    License Agreement.
 
-When ready create a ticket in the [Github issue tracker](https://github.com/spring-projects/spring-framework/issues).
+You do not need to include your token/id. Please add the above statement to all
+future pull requests as well, simply so that the Spring Framework team knows
+immediately that this process is complete.
 
-#### Ticket Lifecycle
+## Create a Branch
 
-When an issue is first created, it may not be assigned and will not have a fix version.
-Within a day or two, the issue is assigned to a specific committer and the target
-version is set to "Waiting for Triage". The committer will then review the issue, ask for
-further information if needed, and based on the findings, the issue is either assigned a fix
-version or rejected.
+### Branch from `master`
 
-When a fix is ready, the issue is marked "Resolved" and may still be re-opened. Once a fix
-is released, the issue is permanently "Closed". If necessary, you will need to create a new,
-related ticket with a fresh description.
+Master currently represents work toward Spring Framework 4.0. Please submit
+all pull requests there, even bug fixes and minor improvements. Backports to
+`3.2.x` will be considered on a case-by-case basis.
 
-#### Submit a Pull Request
 
-You can contribute a source code change by submitting a pull request.
+### Use short branch names
 
-1. If you have not previously done so, please sign the
-[Contributor License Agreement](https://cla.pivotal.io/sign/spring). You will also be reminded
-automatically when you submit a pull request.
+Branches used when submitting pull requests should preferably be named
+according to JIRA issues, e.g. 'SPR-1234'. Otherwise, use succinct, lower-case,
+dash (-) delimited names, such as 'fix-warnings', 'fix-typo', etc. In
+[fork-and-edit][] cases, the GitHub default 'patch-1' is fine as well. This is
+important, because branch names show up in the merge commits that result from
+accepting pull requests and should be as expressive and concise as possible.
 
-1. For all but the most trivial of contributions, please [create a ticket](#create-a-ticket).
-The purpose of the ticket is to understand and discuss the underlying issue or feature.
-We use the GitHub issue tracker as the preferred place of record for conversations and
-conclusions. In that sense discussions directly under a PR are more implementation detail
-oriented and transient in nature.
+## Use Spring Framework Code Style
 
-1. Always check out the `master` branch and submit pull requests against it
-(for target version see [settings.gradle](settings.gradle)).
-Backports to prior versions will be considered on a case-by-case basis and reflected as
-the fix version in the issue tracker.
+The complete [Spring Framework Code Style][] reference is available on the wiki, but
+here's a quick summary:
 
-1. Use short branch names, preferably based on the GitHub issue (e.g. `22276`), or
-otherwise using succinct, lower-case, dash (-) delimited names, such as `fix-warnings`.
+### Mind the whitespace
 
-1. Choose the granularity of your commits consciously and squash commits that represent
-multiple edits or corrections of the same logical change. See
-[Rewriting History section of Pro Git](https://git-scm.com/book/en/Git-Tools-Rewriting-History)
-for an overview of streamlining commit history.
+Please carefully follow the whitespace and formatting conventions already
+present in the framework.
 
-1. Format commit messages using 55 characters for the subject line, 72 lines for the
-description, followed by the issue fixed, e.g. `Fixes #22276`.
-See the
-[Commit Guidelines section of Pro Git](https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines)
-for best practices around commit messages and use `git log` to see some examples.
+1. Tabs, not spaces
+1. Unix (LF), not DOS (CRLF) line endings
+1. Eliminate all trailing whitespace
+1. Wrap Javadoc at 90 characters
+1. Aim to wrap code at 90 characters, but favor readability over wrapping
+1. Preserve existing formatting; i.e. do not reformat code for its own sake
+1. Search the codebase using `git grep` and other tools to discover common
+    naming conventions, etc.
+1. Latin-1 (ISO-8859-1) encoding for Java sources; use `native2ascii` to convert
+    if necessary
 
-1. List the GitHub issue number in the PR description.
 
-If accepted, your contribution may be heavily modified as needed prior to merging.
-You will likely retain author attribution for your Git commits granted that the bulk of
-your changes remain intact. You may also be asked to rework the submission.
+### Add Apache license header to all new classes
 
-If asked to make corrections, simply push the changes against the same branch, and your
-pull request will be updated. In other words, you do not need to create a new pull request
-when asked to make changes.

-See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source)
-wiki page for instructions on how to check out, build, and import the Spring Framework
-source code into your IDE.
+### Update Apache license header in modified files as necessary
 
-### Source Code Style
+Always check the date range in the license header. For example, if you've
+modified a file in 2015 whose header still reads:
 
-The wiki pages
-[Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and

-defines the source file coding standards we use along with some IDEA editor settings we customize.
+```java
+/*
+ * Copyright 2002-2011 the original author or authors.
+```
 
-### Reference Docs
+Then be sure to update it to 2015 accordingly:
 
-The reference documentation is in the [src/docs/asciidoc](src/docs/asciidoc) directory and, in
-[Asciidoctor](https://asciidoctor.org/) format. For trivial changes, you may be able to browse,
-edit source files, and submit directly from GitHub.
+```java
+/*
+ * Copyright 2002-2015 the original author or authors.
+```
 
-When making changes locally, use `./gradlew asciidoctor` and then browse the result under
-`build/asciidoc/html5/index.html`.
+### Use @since tags for newly-added public API types and methods
 
-Asciidoctor also supports live editing. For more details read
-[Editing AsciiDoc with Live Preview](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/).
-Note that if you choose the
-[System Monitor](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/#using-a-system-monitor)
-option, you can find a Guardfile under `src/docs/asciidoc`.
+For example:
+
+```java
+/**
+ * ...
+ *
+ * @author First Last
+ * @since 4.2.3
+ * @see ...
+ */
+```
+
+## Prepare Your Commit
+
+### Submit JUnit test cases for all behavior changes
+
+Search the codebase to find related tests and add additional `@Test` methods
+as appropriate. It is also acceptable to submit test cases on a per JIRA issue
+basis, for example:
+
+```java
+package org.springframework.beans.factory.support;
+
+/**
+ * Unit tests for SPR-8954, in which a custom {@link InstantiationAwareBeanPostProcessor}
+ * forces the predicted type of a FactoryBean, effectively preventing retrieval of the
+ * bean from calls to #getBeansOfType(FactoryBean.class). The implementation of
+ * {@link AbstractBeanFactory#isFactoryBean(String, RootBeanDefinition)} now ensures
+ * that not only the predicted bean type is considered, but also the original bean
+ * definition's beanClass.
+ *
+ * @author Chris Beams
+ */
+public class Spr8954Tests {
+
+    @Test
+    public void cornerSpr8954() {
+        // ...
+    }
+}
+```
+
+
+### Squash commits
+
+Use `git rebase --interactive --autosquash`, `git add --patch`, and other tools
+to "squash" multiple commits into a single atomic commit. In addition to the man
+pages for git, there are many resources online to help you understand how these
+tools work. The [Rewriting History section of Pro Git][] provides a good overview.
+
+
+### Use real name in git commits
+
+Please configure git to use your real first and last name for any commits you
+intend to submit as pull requests. For example, this is not acceptable:
+
+    Author: Nickname <user@mail.com>
+
+Rather, please include your first and last name, properly capitalized, as
+submitted against the Spring Individual Contributor License Agreement (ICLA):
+
+    Author: First Last <user@mail.com>
+
+This helps ensure traceability against the ICLA and also goes a long way to
+ensuring useful output from tools like `git shortlog` and others.
+
+You can configure this via the account admin area in GitHub (useful for
+fork-and-edit cases); _globally_ on your machine with
+
+    git config --global user.name "First Last"
+    git config --global user.email user@mail.com
+
+or _locally_ for the `spring-framework` repository only by omitting the
+'--global' flag:
+
+    cd spring-framework
+    git config user.name "First Last"
+    git config user.email user@mail.com
+
+
+### Format commit messages
+
+Please read and follow the [Commit Guidelines section of Pro Git][].
+
+Most importantly, please format your commit messages in the following way
+(adapted from the commit template in the link above):
+
+    Short (50 chars or less) summary of changes
+
+    More detailed explanatory text, if necessary. Wrap it to about 72
+    characters or so. In some contexts, the first line is treated as the
+    subject of an email and the rest of the text as the body. The blank
+    line separating the summary from the body is critical (unless you omit
+    the body entirely); tools like rebase can get confused if you run the
+    two together.
+
+    Further paragraphs come after blank lines.
+
+     - Bullet points are okay, too
+
+     - Typically a hyphen or asterisk is used for the bullet, preceded by a
+       single space, with blank lines in between, but conventions vary here
+
+    Issue: SPR-1234, SPR-1235
+
+
+1. Use imperative statements in the subject line, e.g. "Fix broken Javadoc link".
+1. Begin the subject line with a capitalized verb, e.g. "Add, Prune, Fix,
+    Introduce, Avoid, etc."
+1. Do not end the subject line with a period.
+1. Restrict the subject line to 50 characters or less if possible.
+1. Wrap lines in the body at 72 characters or less.
+1. Mention associated JIRA issue(s) at the end of the commit comment, prefixed
+    with "Issue: " as above.
+1. In the body of the commit message, explain how things worked before this
+    commit, what has changed, and how things work now.
+
+For examples of this style, issue a `git log --author=cbeams` in the
+`spring-framework` git repository. For convenience, here are several such commits:
+
+- https://github.com/spring-projects/spring-framework/commit/08e2669b84ec0faa2f7904441fe39ac70b65b078

+- https://github.com/spring-projects/spring-framework/commit/b787a68f2050df179f7036b209aa741230a02477
+
+## Run the Final Checklist
+
+### Run all tests prior to submission
+
+See the [building from source][] section of the `README` for instructions. Make
+sure that all tests pass prior to submitting your pull request.
+
+
+### Submit your pull request
+
+Subject line:
+
+Follow the same conventions for pull request subject lines as mentioned above
+for commit message subject lines.
+
+In the body:
+
+1. Explain your use case. What led you to submit this change? Why were existing
+    mechanisms in the framework insufficient? Make a case that this is a
+    general-purpose problem and that yours is a general-purpose solution, etc.
+1. Add any additional information and ask questions; start a conversation or
+    continue one from JIRA.
+1. Mention the JIRA issue ID.
+1. Also mention that you have submitted the ICLA as described above.
+
+Note that for pull requests containing a single commit, GitHub will default the
+subject line and body of the pull request to match the subject line and body of
+the commit message. This is fine, but please also include the items above in the
+body of the request.
+
+
+### Mention your pull request on the associated JIRA issue
+
+Add a comment to the associated JIRA issue(s) linking to your new pull request.
+
+
+### Expect discussion and rework
+
+The Spring team takes a very conservative approach to accepting contributions to
+the framework. This is to keep code quality and stability as high as possible,
+and to keep complexity at a minimum. Your changes, if accepted, may be heavily
+modified prior to merging. You will retain "Author:" attribution for your Git
+commits granted that the bulk of your changes remain intact. You may be asked to
+rework the submission for style (as explained above) and/or substance. Again, we
+strongly recommend discussing any serious submissions with the Spring Framework 
+team _prior_ to engaging in serious development work.
+
+Note that you can always force push (`git push -f`) reworked / rebased commits
+against the branch used to submit your pull request. In other words, you do not
+need to issue a new pull request when asked to make changes.

+## Spring Framework
+The Spring Framework provides a comprehensive programming and configuration
+model for modern Java-based enterprise applications -- on any kind of deployment
+platform. A key element of Spring is infrastructural support at the application
+level: Spring focuses on the "plumbing" of enterprise applications so that teams
+can focus on application-level business logic, without unnecessary ties to
+specific deployment environments.
 
-This is the home of the Spring Framework: the foundation for all [Spring projects](https://spring.io/projects). Collectively the Spring Framework and the family of Spring projects is often referred to simply as "Spring". 
+The framework also serves as the foundation for [Spring Integration][], [Spring Batch][]
+and the rest of the Spring [family of projects][]. Browse the repositories under
+the [Spring organization][] on GitHub for a full list.
 
-Spring provides everything required beyond the Java programming language for creating enterprise applications for a wide range of scenarios and architectures. Please read the [Overview](https://docs.spring.io/spring/docs/current/spring-framework-reference/overview.html#spring-introduction) section as reference for a more complete introduction.

-For access to artifacts or a distribution zip, see the [Spring Framework Artifacts](https://github.com/spring-projects/spring-framework/wiki/Spring-Framework-Artifacts) wiki page.
+## Downloading Artifacts
+See [downloading Spring artifacts][] for Maven repository information. Unable to
+use Maven or other transitive dependency management tools?
+See [building a distribution with dependencies][].
 
 ## Documentation
+See the current [Javadoc][] and [reference docs][].
 
-The Spring Framework maintains reference documentation ([published](https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/) and [source](src/docs/asciidoc)), Github [wiki pages](https://github.com/spring-projects/spring-framework/wiki), and an
-[API reference](https://docs.spring.io/spring-framework/docs/current/javadoc-api/). There are also [guides and tutorials](https://spring.io/guides) across Spring projects.
+## Getting Support
+Check out the [spring][spring tags] tags on [Stack Overflow][]. [Commercial support][]
+is available too.
 
-## Build from Source
+## Issue Tracking
+Report issues via the [Spring Framework JIRA][]. Understand our issue management
+process by reading about [the lifecycle of an issue][]. Think you've found a
+bug? Please consider submitting a reproduction project via the
+[spring-framework-issues][] GitHub repository. The [readme][] there provides
+simple step-by-step instructions.
 
-See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source) Wikipedia page and the [CONTRIBUTING.md](CONTRIBUTING.md) file.
+## Building from Source
+The Spring Framework uses a [Gradle][]-based build system. In the instructions
+below, [`./gradlew`][] is invoked from the root of the source tree and serves as
+a cross-platform, self-contained bootstrap mechanism for the build.
 
-## Stay in Touch
+### Prerequisites
 
-Follow [@SpringCentral](https://twitter.com/springcentral), [@SpringFramework](https://twitter.com/springframework), and its [team members](https://twitter.com/springframework/lists/team/members) on Twitter. In-depth articles can be found at [The Spring Blog](https://spring.io/blog/), and releases are announced via our [news feed](https://spring.io/blog/category/news).
+[Git][] and [JDK 8 update 20 or later][JDK8 build]
+
+Be sure that your `JAVA_HOME` environment variable points to the `jdk1.8.0` folder
+extracted from the JDK download.
+
+### Check out sources
+`git clone git@github.com:spring-projects/spring-framework.git`
+
+### Import sources into your IDE
+Run `./import-into-eclipse.sh` or read `import-into-idea.md` as appropriate.
+> **Note:** Per the prerequisites above, ensure that you have JDK 8 configured properly in your IDE.
+
+### Install all spring-\* jars into your local Maven cache
+`./gradlew install`
+
+### Compile and test; build all jars, distribution zips, and docs
+`./gradlew build`
+
+... and discover more commands with `./gradlew tasks`. See also the [Gradle
+build and release FAQ][].

-== Spring Framework Concourse pipeline
-
-The Spring Framework uses https://concourse-ci.org/[Concourse] for its CI build and other automated tasks.
-The Spring team has a dedicated Concourse instance available at https://ci.spring.io with a build pipeline
-for https://ci.spring.io/teams/spring-framework/pipelines/spring-framework-5.1.x[Spring Framework 5.1.x].
-
-=== Setting up your development environment
-
-If you're part of the Spring Framework project on GitHub, you can get access to CI management features.
-First, you need to go to https://ci.spring.io and install the client CLI for your platform (see bottom right of the screen).
-
-You can then login with the instance using:
-
-[source]
-----
-$ fly -t spring login -n spring-framework -c https://ci.spring.io
-----
-
-Once logged in, you should get something like:
-
-[source]
-----
-$ fly ts
-name                  url                   team                  expiry
-spring                https://ci.spring.io  spring-framework      Wed, 25 Mar 2020 17:45:26 UTC
-----
-
-=== Pipeline configuration and structure
-
-The build pipelines are described in `pipeline.yml` file.
-
-This file is listing Concourse resources, i.e. build inputs and outputs such as container images, artifact repositories, source repositories, notification services, etc.
-
-It also describes jobs (a job is a sequence of inputs, tasks and outputs); jobs are organized by groups.
-
-The `pipeline.yml` definition contains `((parameters))` which are loaded from the `parameters.yml` file or from our https://docs.cloudfoundry.org/credhub/[credhub instance].
-
-You'll find in this folder the following resources:
-
-* `pipeline.yml` the build pipeline
-* `parameters.yml` the build parameters used for the pipeline
-* `images/` holds the container images definitions used in this pipeline
-* `scripts/` holds the build scripts that ship within the CI container images
-* `tasks` contains the task definitions used in the main `pipeline.yml`
-
-=== Updating the build pipeline
-
-Updating files on the repository is not enough to update the build pipeline, as changes need to be applied.
-
-The pipeline can be deployed using the following command:
-
-[source]
-----
-$ fly -t spring set-pipeline -p spring-framework-5.1.x -c ci/pipeline.yml -l ci/parameters.yml
-----
-
-NOTE: This assumes that you have credhub integration configured with the appropriate secrets.

-# Spring Framework - Eclipse/STS Project Import Guide
-
-This document will guide you through the process of importing the Spring Framework
-projects into Eclipse or the Spring Tool Suite (STS). It is recommended that you have a
-recent version of Eclipse or STS. As a bare minimum you will need Eclipse with full Java
-8 support, the AspectJ Development Tools (AJDT), and the Groovy Compiler.
-
-The following instructions have been tested against
-[Spring Tool Suite](https://spring.io/tools) (_STS_) 3.9.4 and 4.0.0.M11 with
-[Eclipse Buildship](https://projects.eclipse.org/projects/tools.buildship) (Eclipse
-Plug-ins for Gradle). The instructions should work with the latest Eclipse distribution
-as long as you install
-[Buildship](https://marketplace.eclipse.org/content/buildship-gradle-integration). Note
-that STS 4 comes with Buildship preinstalled.
-
-## Steps
-
-_Within your locally cloned `spring-framework` working directory:_
-
-1. Precompile `spring-oxm` with `./gradlew :spring-oxm:compileTestJava`
-2. Import into Eclipse (File -> Import -> Gradle -> Existing Gradle Project -> Navigate
-   to directory -> Select Finish)
-3. If prompted, exclude the `spring-aspects` module (or after the import by closing or
-   deleting the project)
-4. In the `spring-oxm` project, add the two folders (`castor` and `jaxb`) in
-   `build/generated-sources` to the build path (right click on them and select
-   `Build Path -> Use as Source Folder`)
-5. To apply project specific settings run `./gradlew eclipseBuildship`
-7. Code away
-
-## Known Issues
-
-1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
-  - See `*RepackJar` tasks in the build.
-2. `spring-aspects` does not compile due to references to aspect types unknown to Eclipse.
-  - If you install [AJDT](https://www.eclipse.org/ajdt/downloads/) into Eclipse it should
-    work.
-3. While JUnit tests pass from the command line with Gradle, some may fail when run from
-   the IDE.
-  - Resolving this is a work in progress.
-  - If attempting to run all JUnit tests from within the IDE, you will likely need to set
-    the following VM options to avoid out of memory errors:
-	`-XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=2048m`
-
-## Tips
-
-In any case, please do not check in your own generated `.classpath` file, `.project`
-file, or `.settings` folder. You'll notice these files are already intentionally in
-`.gitignore`. The same policy holds for IDEA metadata.

+Spring Framework - Eclipse/STS Project Import Guide
+
+This script will guide you through the process of importing the Spring
+Framework projects into Eclipse or the Spring Tool Suite (STS). It is
+recommended that you have a recent version of Eclipse or STS. As a bare
+minimum you will need Eclipse with full Java 8 support, the AspectJ
+Development Tools (AJDT), and the Groovy Compiler.
+
+This script has been tested against:
+
+- STS:     3.6.3.RELEASE (Eclipse Luna SR1 4.4.1)
+- AJDT:    2.2.4.e44x-20141118-0700 (Luna 4.4)
+
+If you need to download and install Eclipse or STS, please do that now
+by visiting one of the following sites:
+
+- Eclipse downloads: https://download.eclipse.org/eclipse/downloads
+- STS downloads: https://spring.io/tools/sts/all
+- STS nightly builds: https://dist.springsource.com/snapshot/STS/nightly-distributions.html
+
+If you need to install a recent CI build for AJDT (i.e., so that the
+spring-aspects module properly compiles in Eclipse/STS), click on the
+"Artifacts" tab of a successful CI build and copy the link to the
+"update site" which you can then use to install or update AJDT within
+Eclipse/STS.
+
+- AJDT CI builds: https://build.spring.io/browse/AJDT-AE44
+
+Once Eclipse/STS is installed, press enter, and we'll begin.

+
+# this command:
+# - wipes out any existing Eclipse metadata
+# - generates OXM test classes to avoid errors on import into Eclipse
+# - generates metadata for all subprojects
+# - skips metadata gen for the root project (-x :eclipse) to work
+#   around Eclipse's inability to import hierarchical project structures
+COMMAND="./gradlew --no-daemon cleanEclipse :spring-oxm:compileTestJava eclipse -x :eclipse"
+
+cat <<EOM
+
+------------------------------------------------------------------------
+STEP 1: Generate subproject Eclipse metadata
+
+The first step will be to generate Eclipse project metadata for each of
+the spring-* subprojects. This happens via the built-in "Gradle wrapper"
+script (./gradlew in this directory). If this is your first time using
+the Gradle wrapper, this step may take a few minutes while a Gradle
+distribution is downloaded for you.
+
+The command run will be:
+
+    $COMMAND
+
+Press enter when ready.
+EOM
+
+read
+
+$COMMAND || exit
+
+cat <<EOM
+
+------------------------------------------------------------------------
+STEP 2: Import subprojects into Eclipse/STS
+
+Within Eclipse/STS, do the following:
+
+- File > Import... > Existing Projects into Workspace
+- When prompted for the 'root directory', provide $PWD.
+- Press enter. You will see the modules show up under "Projects".
+- All projects should be selected/checked. Click Finish.
+- When the project import is complete, you should have no errors.
+
+When the above is complete, return here and press the enter key.
+EOM
+
+read
+
+COMMAND="./gradlew --no-daemon :eclipse"
+
+cat <<EOM
+
+------------------------------------------------------------------------
+STEP 3: Generate root project Eclipse metadata
+
+Unfortunately, Eclipse does not support importing project hierarchies,
+so we had to skip root project metadata generation during step 1. In
+this step we simply generate root project metadata so that you can
+import it in the next step.
+
+The command run will be:
+
+    $COMMAND
+
+Press the enter key when ready.
+EOM
+
+read
+
+$COMMAND || exit
+
+cat <<EOM
+------------------------------------------------------------------------
+STEP 4: Import root project into Eclipse/STS
+
+Follow the project import steps listed in step 2 above to import the
+root "spring" project.
+
+Press enter when complete, and move on to the final step.
+EOM
+
+read
+
+cat <<EOM
+------------------------------------------------------------------------
+STEP 5: Enable Git support for all projects
+
+- In the Eclipse/STS Package Explorer, select all spring* projects.
+- Right-click to open the context menu and select Team > Share Project...
+- In the Share Project dialog that appears, select Git and press Next.
+- Check "Use or create repository in parent folder of project".
+- Click Finish.
+
+When complete, you'll have Git support enabled for all projects.
+
+You're ready to code! Goodbye!

+The following has been tested against Intellij IDEA 13.1
 
 ## Steps
 
 _Within your locally cloned spring-framework working directory:_
 
-1. Precompile `spring-oxm` with `./gradlew :spring-oxm:compileTestJava`
-2. Import into IntelliJ (File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle)
-3. When prompted exclude the `spring-aspects` module (or after the import via File-> Project Structure -> Modules)
-4. Code away
+1. Pre-compile `spring-oxm` with `./gradlew cleanIdea :spring-oxm:compileTestJava`
+2. Import into IDEA (File->import project->import from external model->Gradle)
+3. Set the Project JDK as appropriate (1.8+)
+4. Exclude the `spring-aspects` module (Go to File->Project Structure->Modules)
+5. Code away
 
 ## Known issues
 
-1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
-See `*RepackJar` tasks in the build and https://youtrack.jetbrains.com/issue/IDEA-160605).
-2. `spring-aspects` does not compile due to references to aspect types unknown to
-IntelliJ IDEA. See https://youtrack.jetbrains.com/issue/IDEA-64446 for details. In the meantime, the
-'spring-aspects' can be excluded from the project to avoid compilation errors.
-3. While JUnit tests pass from the command line with Gradle, some may fail when run from
-IntelliJ IDEA. Resolving this is a work in progress. If attempting to run all JUnit tests from within
-IntelliJ IDEA, you will likely need to set the following VM options to avoid out of memory errors:
+1. `spring-oxm` should be pre-compiled since it's using repackaged dependencies (see *RepackJar tasks)
+2. `spring-aspects` does not compile out of the box due to references to aspect types unknown to IDEA.
+See https://youtrack.jetbrains.com/issue/IDEA-64446 for details. In the meantime, the 'spring-aspects'
+should be excluded from the overall project to avoid compilation errors.
+3. While all JUnit tests pass from the command line with Gradle, many will fail when run from IDEA.
+Resolving this is a work in progress. If attempting to run all JUnit tests from within IDEA, you will
+likely need to set the following VM options to avoid out of memory errors:
     -XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=2048m
-4. If you invoke "Rebuild Project" in the IDE, you'll have to generate some test
-resources of the `spring-oxm` module again (`./gradlew :spring-oxm:compileTestJava`)
