+> an app to make DnD NPCs with Elm Land
+
+### overview
+
+My friends and I are starting a new Dungeons and Dragons campaign, and I thought it
+would be fun to use [`elm/random`](https://package.elm-lang.org/packages/elm/random/latest/) to
+generate some NPCs with the click of a button.
+
+
+### local development
+
+```
+npx elm-land server
+```
+
+The app should be running at [http://localhost:1234](http://localhost:1234)
