+love2d signage
+===
+
+As used in digital signage displays in HSWAW.
+
+Originally hosted on code.hackerspace.pl/informatic/love2d-signage, now in hscloud.
+
+
+Building & Running
+---
+
+ $ nix-build -A hswaw.signage.prod
+ $ result/bin/signage
+
+If the result doesn't run and complains about OpenGL not being available, try building the 'local' target instead, which will use your host `<nixpkgs>`:
+
+ $ nix-build -A hswaw.signage.local
+
+For non-NixOS systems you'll need something like `nixgl` to work around Nixpkgs-GL-on-Non-NixOS badness anyways.
+
+Custom configs
+---
+
+You can either modify config.lua and rebuild, or specify a custom config at runtime by settin gthe `SIGNAGE_CONFIG` environment variable.
