# Preface
This section describes in brief some CLI commands. Please read [the general notes on the command line interface ](index ) before continuing.
# Adding users
When first installed, The Arsse has no users configured. You may add users by executing the following command:
```sh
sudo -u www-data php arsse.php user add "user@example.com" "example password"
```
The password argument is optional: if no password is provided, a random one is generated and printed out:
```console
$ sudo -u www-data php arsse.php user add "jane.doe"

# Setting and changing passwords
Setting's a user's password is practically identical to adding a password:
```sh
sudo -u www-data php arsse.php user set-pass "user@example.com" "new password"
```
As when adding a user, the password argument is optional: if no password is provided, a random one is generated and printed out:
```console
$ sudo -u www-data php arsse.php user set-pass "jane.doe"

## Setting and changing passwords for Fever
Before a user can make use of [the Fever protocol ](/en/Supported_Protocols/Fever ), a Fever-specific password for that user must be set. It is _highly recommended_ that this not be the samer as the user's main password. The password can be set by adding the `--fever` option to the normal password-changing command:
```sh
sudo -u www-data php arsse.php user set-pass --fever "user@example.com" "fever password"
```
As when setting a main password, the password argument is optional: if no password is provided, a random one is generated and printed out:
```console
$ sudo -u www-data php arsse.php user set-pass --fever "jane.doe"
