+A service to manage vanity URLs for go packages.
+
+It makes it possible to install tools like this:
+#+begin_src sh
+GOPRIVATE=1 go install -v golang.fcuny.net/tools/cmd/music-organizer@latest
+#+end_src
+
+* Build
+Running =nix build= in the repository will create the binary.
+* Run
+Running =nix run= in the repository will start the server.
+* Deployment
+To update the application with the most recent code, run =make deploy=.
+* Configuration
+Add repositories to the [[file+sys:vanity.yaml][configuration file]].
