+## Building
+
+`gsrsup` builds using a handwritten [Ninja](https://ninja-build.org/) file.
+Simply run `ninja` to create a development build. You can also run Ninja with a
+custom build file to request a different profile:
+
+ - `ninja -f buildconf/asan.ninja`: Build with AddressSanitizer.
+ - `ninja -f buildconf/dbg.ninja`: Build for debugging.
+ - `ninja -f buildconf/release.ninja`: Build with optimizations.
