+This plugin handles scoring and private answer submission and revealing.
+
+### How It Works
+
+#### Scoring
+
+* `SCORE [score]`: Add _score_ to your score.
+* `SCORES`: Show all scores.
+* `CLEAR`: Clear scores.
+
+#### Inputs and Revealing
+
+* `INPUT [answer]`: Set your answer to _answer_.
+* `REVEAL`: Show all submitted answers.
+
+#### Timing
+
+* `START [seconds]`: Start a timer for _seconds_ seconds.  It will send reminders with N minutes remaining, along with 30 and 15 seconds.  When time runs out, `REVEAL` will be called automatically.
+* `STOP`: Stops all timers.
+
+### To-Do
+
+* Allow the specification of a game leader, who is the only person who can `REVEAL`.
