-#### Optional Start Parameters
+#### Update Settings Command (`updateSettings`)
 
-The Start-Command may contain an optional Pomodoro-Config, which allows you to customize the length of the work session, short break, long break, and the number of sessions. If no configuration is provided, the server will use default values.
+The `updateSettings` command allows clients to modify the Pomodoro timer configuration, including the length of work sessions, short breaks, long breaks, and the total number of sessions in a cycle. This command must include a valid password to be accepted by the server. The updateSettings command can be used when the timer is stopped.
 
-Example:
-```json
-{
-    command: "start",
-    password: "foobar",
-    config: {
-        "work": 10,          // Length of the work session in seconds
-        "shortBreak": 5,     // Length of the short break in seconds
-        "longBreak": 10,     // Length of the long break in seconds
-        "sessions": 2        // Number of total sessions
-    }
-}
-```
+- Fields in the `settings` Object:
+  - `work`: Length of the work session (in seconds).
+  - `shortBreak`: Length of the short break (in seconds).
+  - `longBreak`: Length of the long break (in seconds).
+  - `sessions`: Total number of work/break sessions in the Pomodoro cycle.
+
+All fields are mandatory and may not be ommitted.
