+there's no configuration besides a `.env` file with two keys:
+
+- the bot's token `DISCORD_TOKEN`,
+- channel id for a sentence game `SENTENCE_CHANNEL`. if you don't want to enable the sentence game, set the key to `-1`.
 
 ## why?
 because we needed a tiny, self hostable bot to remember things of importance for our equally tiny discord server.
 
 ## what it do?
-DMs a user a link to any message they reacte with 🔖 to (tip: you can change the `EMOJI` constant in `bot.rb` to any built-in emoji). also sends part of the message for quick access. that's it.
+- DMs a user a link to any message they react with 🔖 to (tip: you can change the `BOOKMARK_EMOJI` constant in `bot.rb` to any built-in emoji). this also sends part of the message for quick access,
+- lets users pin messages to the channel by reacting with 📌 on that message (change `PIN_EMOJI` to change the emoji). if there are no more of that emoji reactions on the message, it gets unpinned.
+- lets users make sentences one word (or more) at a time in `SENTENCE_CHANNEL`. to finish a sentence, send either of these as a message: `?`, `!`, `.`, `...`, `?!`
 
 ## how?
 requires [ruby](https://www.ruby-lang.org/) >= 3.0 and [bundler](https://bundler.io) >= 2.3.19. the only two dependencies are `dotenv` and `discordrb`, as specified in the `Gemfile`.
+
+quick setup:
 ```bash
+$ git clone https://git.poto.cafe/yagich/potomark-bot-rb.git && cd potomark-bot-rb
 $ echo 'DISCORD_TOKEN=YOUR.DISCORD.TOKEN.HERE' > .env
+$ echo 'SENTENCE_CHANNEL=SENTENCE_GAME_CHANNEL_ID' >> .env
 $ bundle install
 $ ruby bot.rb
 ```
