-Set your Slack status via the command line
+Set your Slack status via the command line
+
+## Example usage
+
+Set auth token (it will store it in `~/.config/slack-status-cli` or your `$XDG_CONFIG_HOME` dir
+
+    slack-status -auth-token <your auth token>
+
+Set status without emoji
+
+    slack-status Walking the dog
+
+Set status with emoji
+
+    slack-status :walking-the-dog: Walking the dog
+    slack-status --emoji :walking-the-dog: Walking the dog
+
+Set status with duration (eg. `10m`, `2h`, `7d12h`)
+
+    slack-status 10m :walking-the-dog: Walking the dog
+    slack-status :walking-the-dog: Walking the dog for 10m
+    slack-status --duration 10m --emoji :walking-the-dog: Walking the dog
+
+Set status with duration and snooze notifications
+
+    slack-status --snooze --duration 12h --emoji :bed: Good night
+    slack-status --snooze :bed: Good night for 12h
+
+Set a status that contains a duration
+
+    # Set status to "On a break" for 5 minutes
+    slack-status :sleeping: On a break for 5m
+    # Set status to "On a break for 5m"  for 5 minutes
+    slack-status --duration 5m :sleeping: On a break for 5m
+    # Set status to "On a break for 5m"  with no duration
+    slack-status :sleeping: "On a break for 5m"
+
+Clear existing status and snooze durations
+
+    slack-status
+
+Snooze notifications without updating your status
+
+    slack-status --duration 15m --snooze
+
+## Future
+
+I plan to do a bit of work to bundle this for easier distribution and maybe support multiple workspaces.
