 # servicepoint-life
 
-More fully featured game of life for the servicepoint display based on the example in the repo.
+This is a small terminal app that generates conways game of life rules and simulates them on the servicepoint display.
 
+It uses the [servicepoint](https://git.berlin.ccc.de/servicepoint/servicepoint/) library for the display commands.
 
+## Running
+
+With Nix flakes, you can just `nix run git+https://git.berlin.ccc.de/vinzenz/servicepoint-life`.
+
+Otherwise, you can `cargo install --git https://git.berlin.ccc.de/vinzenz/servicepoint-life` and then run `servicepoint-life`.
+
+If you want to poke at the code you can always check out the repo and `cargo run` it.
