-# Core PowerShell Host
-
-This host is based off the infamous `host06` example. It relies only on managed
-code, and is cross-platform. It needs a fair bit of work, but it loads
-profiles, has tab-completion, and can be used to debug PowerShell scripts.
-
-## Executable
-
-The `bin/powershell[.exe]` executable for Core PowerShell is built by this
-project, as it is the top dependency of the graph, and has `emitEntryPoint:
-true`, meaning a native executable is produced automatically by CLI (no need to
-own a separate native host). It is also the project that deploys the `ps1xml`
-types and formatting files, as well as the default profile and the included
-PowerShell modules.
-
-Note that many of these should probably live with System.Management.Automation,
-but we're waiting on a bug fix from CLI to move them.
-
-## update-content.sh
-
-This script is used to update our current tree's files with those that live in
-`src/monad`. We only need to update them when new changes are merged from
-Source Depot, and the build scripts are much simpler without this logic. With
-the files living here, the `content` key in the `project.json` handles the
-deployment for us in a cross-platform manner.
