+Install the `armv5te-musl` toolchain
 
-This template uses `cargo vendor` to cache all dependencies for the docker build. Before the first run and after changes to your dependencies you need to rebuild this dependency cache
 ```bash
-make install-dependencies

 ## Usage
 
+Build this project:
+
 ```bash
-make build
