 The project was originally intended to assist in the development of the Windows implementation of the [tinygo-org/bluetooth](https://github.com/tinygo-org/bluetooth) library.
 That's why it currently only contains WinRT APIs related to Bluetooth, but we are open to include new APIs if requested.
 
-> **Note**
-> Notice that the code generator is not capable of generating any WinRT types.
-> It will work with most of them, but we've added the functionalities we exclusively needed to generate the BLE APIs.
-> So some things may still be missing.
-> Check out the [known missing features](#known-missing-features) section below for more information.
+> [!IMPORTANT]
+> Due to the nature of this project we decided not to tag any releases.
+> All commits to the `main` branch are considered stable, and we encourage you to use the latest commit available.

+> Breaking changes in the `main` branch should be an exception, but we may include them in favor of the simplicity of the project.
 
 The project also contains the `winrt-go-gen` code generator and the source Windows Metadata (WinMD) files (located in `/internal/winmd/metadata`) that describe the WinRT APIs.

 ## Generated code
 
 All the generated code is stored in the `windows` folder, and is divided in folders that match the namespace of each class.

 This is because Go does not support method overloading, so we are using the overload name defined in the WinMD files.
 The [`GetGattServicesAsync` method](https://docs.microsoft.com/en-us/uwp/api/windows.devices.bluetooth.bluetoothledevice.getgattservicesasync?view=winrt-22621), for example, has an attribute defining the following overload name: `GetGattServicesWithCacheModeAsync`.
 
+This also affects static methods, which include their class name as prefix to avoid collisions between classes inside the same package.

 ## Generating the code
 
 The code is generated using `go generate`. But the Makefile includes a target (`make gen-files`) that removes all generated code and executes the `go generate` command.
