+## Versioning
 
-## Branches
+This repositories follows the same branch versioning as the main [Godot Engine
+repository](https://github.com/godotengine/godot):
 
-We maintain branches on this repo that relate directly to the main builds of Godot.
-Make sure you use the correct branch for the version of Godot you are using!
+- `master` tracks the current development branch. As this is a moving target,
+  the headers in this repository may not always be fully in sync with upstream.
+  See [**Updating Headers**](#updating-headers) if you need to bring
+  them up to date.
+- `3.x` tracks the development of the next 3.x minor release. Like `master`, it
+  might not always be fully up-to-date with upstream.
+- Other versioned branches (e.g. `3.3`, `3.2`) track the latest stable release
+  in the corresponding branch.
 
-| Branch | Version of Godot |
-| --- | --- |
-| [master](https://github.com/GodotNativeTools/godot_headers) | Godot master  |
-| [3.2](https://github.com/GodotNativeTools/godot_headers/tree/3.2) | Godot 3.2.x  |
-| [3.1](https://github.com/GodotNativeTools/godot_headers/tree/3.1) | Godot 3.1.x  |
-| [3.0](https://github.com/GodotNativeTools/godot_headers/tree/3.0) | Godot 3.0.x  |
+Stable releases are also tagged on this repository:
+[**Tags**](https://github.com/godotengine/godot-headers/tags).
+
+**For any project built against a stable release of Godot, we recommend using
+this repository as a Git submodule, checking out the specific tag matching your
+Godot version.**

+## Updating Headers
+
+See [**Versioning**](#versioning) for details on the Godot versions tracked by
+each branch of this repository.
+
+If the relevant branch is not up-to-date for your needs, or if you want to sync
+the headers with your own modified version of Godot, here is the update
+procedure used to sync this repository with upstream releases:
+
+- Compile [Godot Engine](https://github.com/godotengine/godot) at the specific
+  version/commit which you are using.
+- Use the compiled executable to generate the `api.json` file with:
+  `godot --gdnative-generate-json-api api.json`
+- Copy the file `modules/gdnative/gdnative_api.json` to this repository.
+- Copy the files and folders from `modules/gdnative/include` to this repository,
+  overwriting existing content. (To be sure to be in sync, you can delete the
+  folders of this repository first, then copy the upstream folders in place.)
+  Make sure that you compiled the correct Godot version so that the generated
+  `gdnative_api_struct.gen.h` is up-to-date.
