 typically have a master switch to enable/disable it and some other configuration.
 Configuration is specific to each server the bot is invited to.
 
-For all the examples here, I'm assuming the default command prefix of `$rb_`.
-If you set a different one in `config.py`, translate accordingly.
-
 ## Log channel
 
 The first thing you'll want to do is configure a channel where bot messages
 type
 
 ```
-$rb_config setwarningchannel
+/config setwarningchannel
 ```
 
 This ensures warnings will go somewhere appropriate.
 their attention. E.g. to tag the `@Mod` role type
 
 ```
-$rb_config setwarningmention @Mod
+/config setwarningmention @Mod
 ```
 
 Entering that will configure who to mention, and it will also mention them right
 ## Help!!
 
 I don't remember the commands for my own bot, so I don't expect you will either.
-The only thing you need to remember is `$rb_help`. The bot will reply with a
-summary of all the top-level commands available. As an example:
-
-```
-Auto Kick:
-  autokick       Automatically kicks all new users as soon as they join
-Configuration:
-  config         Manages general bot configuration
-Crosspost Detection:
-  crosspost      Manages crosspost detection and handling
-General:
-  deletemessages Mass deletes messages
-  hello          Simple test reply
-  shutdown       Shuts down the bot
-  testwarn       Posts a test warning
-Join Age:
-  joinage        Tracks recently joined users with options to mass kick or ban
-Join Raids:
-  joinraid       Manages join raid detection and handling
-Logging:
-  logging        Manages event logging
-Pattern Matching:
-  pattern        Manages message pattern matching
-URL Spam:
-  urlspam        Manages URL spam detection
-Username Pattern:
-  username       Manages username pattern detection
-No Category:
-  help           Shows this message
-
-Type $rb_help command for more info on a command.
-You can also type $rb_help category for more info on a category.

+## Configuration
 
-Commands:
-  getwarningchannel Shows the mod warning channel
-  getwarningmention Shows the user/role to mention in warning messages
-  setwarningchannel Sets the mod warning channel
-  setwarningmention Sets a user/role to mention in warning messages
+There are four top-level commands used for configuring most functionality.

-You can also type $rb_help category for more info on a category.
-```
+- `/get <setting>` - Shows the current value for a configuration setting.
+- `/set <setting> <new_value>` - Sets a new value.
+- `/enable <module>` - Enables a module.
+- `/disable <module>` - Disables a module.

 ### Autokick
 
 supervise and disable as soon as the threat has passed.
 
 Subcommands
-- `enable`/`disable` - Toggle autokicking
-- `getbancount`/`setbancount` - If the same person keeps rejoining after being
+- `/enable` or `/disable autokick` - Toggle autokicking
+- `/get` or `/set autokick_bancount` - If the same person keeps rejoining after being
     kicked, ban them after this many rejoins.
-- `getofflineonly`/`setofflineonly` - Whether to only kick users who join with
+- `/get` or `/set autokick_offlineonly` - Whether to only kick users who join with
     a status of offline. That's not impossible in ordinary use, but it's
     suspect and likely indicative of bots versus real users.
 
 General config that isn't specific to one cog.
 
 Subcommands
-- `getwarningchannel`/`setwarningchannel` - Determines the channel where log
+- `/config get_warning_channel` or `set_warning_channel` - Determines the channel where log
     messages are posted. Setting the warning channel doesn't take an argument; it
     uses the current channel you typed the command in.
-- `getwarningmention`/`setwarningmention` - The user or role you want tagged when
+- `/config get_warning_mention` or `set_warning_mention` - The user or role you want tagged when
     the bot needs to alert someone of suspicious activity. Needs to be a proper
     autocompleted @ mention, not just the name.
 
+### Bang Commands
+
+Bang commands are one-word chat commands starting with an exclamation (a "bang")
+similar to what Twitch bots use. When a user types the command by itself in a
+message, the bot will respond with the configured text. E.g. a `!rules` command
+can be defined that summarizes the guild rules, and typing `!rules` in chat
+will get a reply with the list of rules.
+
+Subcommands
+- `/command define` - Defines a command or redefines an existing one.
+- `/command undefine` - Deletes a previously created command.
+- `/command list` - Lists all defined commands.
+- `/command invoke` - Silently invokes a bang command without typing anything visible in chat
+
 ### Crosspost detection
 
 Detects an extremely common pattern we see of someone joining and copy/pasting
 time span, it's ban hammer time.
 
 Subcommands
-- `enable`/`disable` - Master toggle for this entire feature.
-- `getwarncount`/`setwarncount` - How many duplicate messages will cause a
+- `/enable` or /`disable crosspost` - Master toggle for this entire feature.
+- `/get` or `/set crosspost_warncount` - How many duplicate messages will cause a
     warning message to be posted that alerts the mods.
-- `getbancount`/`setbancount` - How many duplicate messages should result in an
+- `/get` or `/set crosspost_bancount` - How many duplicate messages should result in an
     automatic ban. Should be greater than the warning count.
-- `gettimespan`/`settimespan` - Sets the time window within which to look for
+- `/get` or `/set crosspost_timespan` - Sets the time window within which to look for
     duplicates. Value is in seconds. Spammers usually fire these off very quickly,
     so a minute or less is more than enough.
-- `getminlength`/`setminlength` - For text-only messages, sets the minimum length
+- `/get` or `/set crosspost_minlength` - For text-only messages, sets the minimum length
     to be considered for duplicate detection. Maybe a benign (but annoying) user
     posts "lol" at everything in multiple channels. Use this to filter for that
     case.
 These are just general top-level commands, not subcommands.
 
 Commands
-- `deletemessages <@user> <timespan>` - Manually deletes a bunch of messages by a
+- `/delete_messages <@user> <timespan>` - Manually deletes a bunch of messages by a
     particular user. Useful if you banned but accidentally forgot to delete
     recent history, or to clean up after someone had a bit of a manic posting
     spree. The timespan is a value like "30s" for 30 seconds, "5m" for 5
     minutes, or "1h30m" for an hour and a half. NOTE: This only works for fairly
     recent messages. You can't use it to delete things posted way back in the
     scrollback.
-- `hello` - Just for testing bot responsiveness. Or a desperate need to be seen.
-- `shutdown` - Terminates the bot. I forgot this was here. I've never needed it.
+- `/hello` - Just for testing bot responsiveness. Or a desperate need to be seen.
+- `/shutdown` - Terminates the bot. I forgot this was here. I've never needed it.
     If somehow the bot goes rogue and you're not there to ctrl+C it, use this.
-- `testwarn` - Posts a test mod warning in the configured warning channel with
+- `/testwarn` - Posts a test mod warning in the configured warning channel with
     the configured mention user/role.
 
-### Join age
-
-This cog isn't really needed any more since the Members tab was added to Discord.
-It's used for seeing who joined most recently. The list of recent joins is only
-kept in memory, and it keeps a limited number, so it's really only useful for
-the past few days.
-
-Subcommands
-- `enable`/`disable` - Toggle join tracking.
-- `getjointime`/`setjointime` - How long to track a join, in seconds.
-- `search <timespan>` - Shows all users who joined in the last x length of time.
-    Values are like `30s` for 30 seconds, `5m` for 5 minutes, `1h30m` for an hour
-    and a half, etc.

 ### Join raids
 
 While not as common in the past year or two, we used to get a suspicious number
 spikes in joins.
 
 Subcommands
-- `enable`/`disable` - Toggle the feature.
-- `getjoincount`/`setjoincount` - Sets the minimum number of suspicious joins.
-- `getjointime`/`setjointime` - Sets the span of time that number of joins must

 Subcommands
-- `enable`/`disable` - You get the full firehose or you get nothing.
+- `/enable` or `/disable logging` - You get the full firehose or you get nothing.
 
 ### Patterns
 
 of complex and is detailed in its [own document](patterns.md).
 
 Subcommands
-- `add ...` - Adds a new pattern to look for (see [Patterns](patterns.md)).
-- `remove <name>` - Removes a previously added pattern by name.
-- `list` - Show all configured patterns.
-- `setpriority <name> <priority>` - Alters the priority of a pattern. The

+- `/pattern remove <name>` - Removes a previously added pattern by name.
+- `/pattern list` - Show all configured patterns.
+- `/pattern setpriority <name> <priority>` - Alters the priority of a pattern. The
     priority is a unitless value used to pick which pattern wins if a message
     matches more than one. Patterns without priorities set have a default value
     of 100. The highest value wins.

docs/patterns.md

 complexity without needing to make code changes in the bot and redeploy it. A
 guild can have any number of custom patterns. The commands are:
 
-* `$rb_pattern add <name> <statement>` - Add a new named pattern
-* `$rb_pattern remove <name>` - Remove a named pattern
-* `$rb_pattern list` - List all named patterns
+* `/pattern add <name> <statement>` - Add a new named pattern
+* `/pattern remove <name>` - Remove a named pattern
+* `/pattern list` - List all named patterns
 
 The pattern `<name>` can be anything. If it contains spaces, enclose it in
 double quotes, e.g. `"my filter"`.
 Automatically delete a banned word:
 
 ```
-$rb_pattern add "bad word" delete if content.plain contains "darn"
+/pattern add "bad word" delete if content.plain contains "darn"
 ```
 
 Ban anyone who posts a URL within the first 30 minutes of joining the server.
 
 ```
-$rb_pattern add "url spam" ban if author.joinage < 30m and (content.plain contains "http://" or content.plain contains "https://")
+/pattern add "url spam" ban if author.joinage < 30m and (content.plain contains "http://" or content.plain contains "https://")
 ```
 
 Automatically reply to anyone asking when lunch is.
 
 ```
-$rb_pattern add "lunch" reply "Lunch is at noon." if content.plain == "When is lunch?"
+/pattern add "lunch" reply "Lunch is at noon." if content.plain == "When is lunch?"
 ```
 
 ## Grammar

docs/setup.md

 setting files are a good candidate for timely backups, btw, if that influences
 your choice. Maybe a synced cloud folder?)
 
-If you'd like, you can also change the command prefix. The bot recognizes commands
-by looking for messages that start with this prefix. E.g. if the prefix is `$rb_`
-(the default) then typing the message `$rb_help` will invoke the `help` command
-and respond with a list of other commands.
-
 ## Run the script
 
 I wrote this for Python 3.9, and its only dependency is the Discord.py library.
     python main.py
     ```
 
-It will take a few seconds to connect and when you see output like this it means
-it's ready and listening for things to happen.
