+## Selecting a microcontroller
+
+This crate supports multiple microcontrollers in the
+stm32f7 family. Which specific microcontroller you want to build for has to be
+specified with a feature, for example `stm32f767`. 
+
+If no microcontroller is specified, the crate will not compile.
+
+### Supported Microcontrollers
+
+* `stm32f722`
+* `stm32f723`
+* `stm32f730`
+* `stm32f732`
+* `stm32f733`
+* `stm32f745`
+* `stm32f746`
+* `stm32f756`
+* `stm32f765`
+* `stm32f767`
+* `stm32f769`
+* `stm32f777`
+* `stm32f778`
+* `stm32f779`
+
+## Using as a Dependency
+
+When using this crate as a dependency in your project, the microcontroller can 
+be specified as part of the `Cargo.toml` definition.
