+# Vaccins
+
+To start your Phoenix server:
+
+  * Install dependencies with `mix deps.get`
+  * Install Node.js dependencies with `npm install` inside the `assets` directory
+  * Start Phoenix endpoint with `mix phx.server`
+
+Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
+
+Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).
