+# All my Friends
+
+This is scratching a weird itch that started when I saw my friends mostly online.
+
+## Important paths
+
+* `src/heyarne/all_my_friends/server.clj`: Contains a simple HTTP server that serves static files and has a handler for uploads
+* `src/heyarne/all_my_friends/client.cljs`: Is the starting point for the client application
+* `resources/config.edn`: Uses [aero](https://github.com/juxt/aero/tree/1ecae6465405643aaacd54b9b45b4fdb92d1cf7a) for configuration.
+* `resources/public`: Contains HTML and CSS files. `resources/public/js` is automatically compiled.
+* `deps.edn`: Client and server dependencies and build configuration
+* `shadow-cljs.edn`: Client-side build config for [shadow-cljs](https://shadow-cljs.github.io/docs/UsersGuide.html)
