 Sokobot is available on top.gg and can be added to your server [in one click](https://top.gg/bot/713635251703906336/)! You can alternatively add it using the direct link [here](https://discord.com/api/oauth2/authorize?client_id=713635251703906336&permissions=8192&scope=bot).
 ### Self-hosting
 Grab the [latest .jar](https://github.com/PolyMarsDev/Sokobot/releases) or [build it yourself](#compiling). Then, create a Discord Bot Application [here](https://discord.com/developers/applications/) and paste the bot token into ``token.txt``. Then, ensure the two files are in the same directory and run the .jar file.
+Please note, this bot differs a bit from the public bot. For example, there is no voting rewards (custom emotes are always unlocked), no leaderboard, no progress saving, etc.
