+### Initial setup
+
+Now you have a Tilde Friends instance running. The first thing you'll want to do is create your account. Click "login" in the top right corner, then "Register".
+Enter your username and password.
+
+> The first user to create an account and log in will be granted administrative privileges.
+> Further administration can be done at <http://localhost:12345/~core/admin/>
+
+Next, create a Scuttlebutt identity by pressing the "Create an identity" button.
+This will create a pair of keys that are used to sign your messages with.
+
+Because of the way Scuttlebutt is designed, you cannot log into your account without your keys. 
+Tilde Friends locks your keys behind a password, but if you were to destroy your database, the keys would be gone forever, and with it your possibility to send messages using this account. Click on the `identity` app and under "Identities", export your newly created identity.
+
+You'll be prompted with a dialog box saying "This app is requesting the following permission:ssb_id_export".
+This is because applications are not trusted to have access to your keys by default.
+Click on "Allow" and you'll see a list of 12 words. You need to write those down in a password manager or on a piece of paperand keep it private and secure.
+
+> Warning: Nobody needs to know these 12 words. Anybody that has access to those keys can post messages as you, see your private messages and documents and much more.
+
+Now that your keys are safe, we can start connecting to the outside world.
+
+### Replication
+
+You've probably noticed asdtring of random characters by now. This is your public key, a unique identifier for your account you can share to anyone. If you go back to the home menu and into the `ssb` app, you can click on your public key. This will lead you to your profile, which is empty at the time. Edit it and enter your name.
