+Increase Bus Factor by providing ssh access to server.
+
+# How it works
+
++ The server admin runs the installation and sets a password, ssh-key, number
+  of days to add the key after.
++ The server admin gives the "bus factor" the password.
++ In case of an incident, the "bus factor" visits the webpage and enters the
+  provided password.
++ If the correct password is entered, the server admin is notified via all the
+  configured backends that the correct password has been added.
++ If the server admin doesn't wish the ssh-key to be added, they can login and
+  run `cancel-adding-key.sh` in the installation directory.
+	+ If the command is run within the configured number of days, then the key
+	  is not added and everything returns back to normal and the server starts
+	  listening for password again. No new setup is necessary.
+	+ If the command is not run within the configured number of days, then the
+	  ssh key is added.
+
+
+# Installation
+
++ Clone the repository.
+	+ `git clone https://gitlab.com/ceda_ei/the-long-night.git`
++ Install the dependencies
+	+ `pip3 install -r requirements.txt`
++ Create a config file by running `./installation.py`.
++ Install `gunicorn`.
+	+ `pip3 install gunicorn`
++ Run `gunicorn3 -b 127.0.0.1:5000 server:app`. Change port if you want to run
+  gunicorn on a different port.
++ Set up a reverse proxy from your webserver to `localhost:5000`.
