README: Cleanup, add Versioning and Update sections
This clarifies the correspondance between this repo's branches and the upstream ones, as well as documents the update workflow used by maintainers to sync the headers, which can be used by anyone for their own builds (or if they're running cutting edge Godot snapshots before this repo gets updated).

 # godot-headers

-#### `GDNative / NativeScript`
+This repository contains C headers for
+[**Godot Engine**](https://github.com/godotengine/godot)'s *GDNative* API,
+which can be used to write *NativeScripts*.

-> `GDNative` enables the use of dynamically linked libraries inside of [**Godot**](https://github.com/godotengine/godot).
+> `GDNative` enables the use of dynamically linked libraries inside of

+## Versioning
+
+This repositories follows the same branch versioning as the main [Godot Engine
+repository](https://github.com/godotengine/godot):
+
+- `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.
+
+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.
