 To specify package features you can use the following syntax: `imgui[docking-experimental,freetype,sdl2-binding,opengl3-binding]`. To disable the [default features](https://learn.microsoft.com/en-us/vcpkg/concepts/default-features) you can do: `cpp-httplib[core,openssl]`
 
-The `overlay-ports` feature allows you to embed vcpkg ports inside your project, without having to fork the main vcpkg registry or creating a custom registry. You can find more information in the relevant [documentation](https://learn.microsoft.com/en-us/vcpkg/concepts/overlay-ports). The `overlay-triplets` feature allows you to customize triplets and change the default behavior (for example always preferring static libraries on Windows). To specify both in one go you can do `[vcpkg].overlay = "my-overlay"`.
