 # Go wrapper library for OpenCL 2.2
 
+This library provides a complete wrapper for the OpenCL 2.2 API.
+If you require a different API level, refer to [the opencl-go project][opencl-go] to see which versions are available.
+
 **This is work-in-progress. The wrapper is not yet in a state to provide useful functionality**
 
+## Usage
+
+To build and work with this library, you need an OpenCL SDK installed on your system.
+Refer to [the documentation on opencl-go][opencl-go] on how to do this.
+
+The API requires knowledge of the [OpenCL API][opencl-api]. While the wrapper hides some low-level C-API details,
+there is still heavy use of `unsafe.Pointer` and the potential for memory access-violations if used wrong.

 // It also provides convenience functions where practical. For example: PlatformInfoString().
