+# Directory contents
+
+This directory contains the changes that are required to make Agama Live to
+work with the HTTP-based version of Agama. In the future, it should contains all
+the files.
+
+## Skipping the authentication
+
+In order to skip the authentication, we decided to inject a valid authentication
+token in the browser. This token is autogenerated by the `agama-web-server serve`
+command (using the `--generate-token` option).
+
+Then, the Firefox start-up script (`startup`) takes care of injecting such a token
+in the cookies database (`/root/.mozilla/firefox/profile/cookies.sqlite`).
