+# ♜ Rook
+
+Secure secret and file sharing using WebRTC.
+
+### Running locally
+
+Before starting please ensure that you have both [Elixir](https://elixir-lang.org/install.html) and [Yarn](https://classic.yarnpkg.com/en/docs/install/) installed.
+
+To quickly set up all dependencies needed by both the server and the client run:
+
+```sh
+$ mix setup
+```
+
+To then run the app, run either:
+
+```sh
+$ mix phx.server
+```
+
+or
+
+```sh
+$ iex -S mix phx.server
+```
+
+to get an interactive IEx session.

+
+Have fun!
