 * `ssh-agent` must be running in the current session.
 
+## Installation
+Just save the file `bw_add_sshkeys.py` in a folder where it can by found when calling it from the command line. On linux you can see these folders by running `echo $PATH` from the command line. To install for a single user, you can - for example - save the script under `~/.local/bin/` and make it executable by running `chmod +x ~/.local/bin/bw_add_sshkeys.py`.

+## Setting up the Bitwarden CLI tool
+Download the [Bitwarden CLI](https://bitwarden.com/help/cli/), extract the binary from the zip file, make it executable and add it to your path so that it can be found on the command line.
+
+On linux you will likely want to move the executable to `~/.local/bin` and make it executable `chmod +x ~/.local/bin/bw`. `~/.local/bin` is likely already set as a path. You can confirm that by running `which bw`, which should return the path to the executable. You can use the same approach to turn `bw_add_sshkeys.py` into an executable.
+
+If you want to build the Bitwarden CLI by yourself, see [these instructions on the bitwarden github page](https://contributing.bitwarden.com/getting-started/clients/cli).
