+# Flags
+
+WeTTY can be run with the `--help` flag to get a full list of flags.
+
+## Server Port
+
+WeTTY runs on port `3000` by default. You can change the default port by
+starting with the `--port` or `-p` flag.
+
+## SSH Host
+
+If WeTTY is run as root while the host is set as the local machine it will use
+the `login` binary rather than ssh. If no host is specified it will use
+`localhost` as the ssh host.
+
+If instead you wish to connect to a remote host you can specify the host with
+the `--ssh-host` flag and pass the IP or DNS address of the host you want to
+connect to.
+
+## Default User
+
+You can specify the default user used to ssh to a host using the `--ssh-user`.
+This user can overwritten by going to
+`http://yourserver:3000/wetty/ssh/<username>`. If this is left blank a user will
+be prompted to enter their username when they connect.
+
+## SSH Port
+
+By default WeTTY will try to ssh to port `22`, if your host uses an alternative
+ssh port this can be specified with the flag `--ssh-port`.
+
+## WeTTY URL
+
+If you'd prefer an HTTP base prefix other than `/wetty`, you can specify that
+with `--base`.
+
+**Do not set this to `/ssh/${something}`, as this will break username matching
+code.**
