Currently, the project README lists some (but not all) of the available commands.

Unfortunately, it's not possible to see a full list ingame. Potential improvement ideas (goals):

• The list of slash commands is printed if typing /rarity (default, in addition to opening the UI)
• It's also available as a separate /rarity help command - similar to typical CLI programs
• The list in the project README should probably be synchronized with this, automatically if possible

Some of the commands also are misleading (e.g., /rarity validate has frequently confused users). So they need to be revisited.
