+#### Dependencies
 
 - On macOS, you need Xcode or Command Line Tools for Xcode (`xcode-select --install`) for required headers and libraries.
 - On Ubuntu/Debian-like Linux distributions, you need `libgl1-mesa-dev xorg-dev`.
 - On CentOS/Fedora-like Linux distributions, you need `libX11-devel libXcursor-devel libXrandr-devel libXinerama-devel mesa-libGL-devel libXi-devel`.
 
+#### Building Locally
+
+There are various make targets available, the most obvious being:
+
+```
+make test
+make build
+make install
+```
+
+As long as you have your `GOBIN` environment variable set up properly (and in `PATH`), you should be able to run `aminal`.
