 `abra` is a command-line tool for managing your own [Co-op Cloud](https://coopcloud.tech). It can provision new servers, create apps, deploy them, run backup and restore operations and a whole lot of other things. Please see [docs.coopcloud.tech](https://docs.coopcloud.tech) for more extensive documentation.
 
+## Quick install
+
+```bash
+curl https://install.abra.autonomic.zone | bash
+```
+
+Or using the latest release candidate (extra experimental!):
+
+```bash
+curl https://install.abra.autonomic.zone | bash -s -- --rc
+```

+Woops, Abra is unable to connect to connect to %s.
+
+Here are a few tips for debugging your local SSH config. Abra uses plain 'ol
+SSH to make connections to servers, so if your SSH config is working, Abra is
+working.
+
+In the first place, Abra will always try to read your Docker context connection
+string for SSH connection details. You can view your server context configs
+with the following command. Are they correct?
+
+    abra server ls
+
+Is your ssh-agent running? You can start it by running the following command:
+
+    eval "$(ssh-agent)"
+
+If your SSH private key loaded? You can check by running the following command:
+
+    ssh-add -L
+
+If you are using a non-default public/private key, you can configure this in
+your ~/.ssh/config file which Abra will read in order to figure out connection
+details:
+
+Host foo.coopcloud.tech
+  Hostname foo.coopcloud.tech
+  User bar
+  Port 12345
+  IdentityFile ~/.ssh/bar@foo.coopcloud.tech
+
+If you're only using password authentication, you can use the following config:
+
+Host foo.coopcloud.tech
+  Hostname foo.coopcloud.tech
+  User bar
+  Port 12345
+  PreferredAuthentications=password
+  PubkeyAuthentication=no
+
+Good luck!
