 The following settings aren't required for setup and can be left on their defaults.
 
 ### MAINPROMPT_LAST
-If set to true Slaude will try to move the main prompt, which is usually the block of text before the character definitions, to the bottom of the prompt we send to Slack. Can be helpful when as the context grows because this prevents the main prompt from being the first thing that falls out of memory.
+If set to true Slaude will try to move the main prompt, which is usually the block of text before the character definitions, to the bottom of the prompt we send to Slack. Can be helpful when as the context grows because this prevents the main prompt from being the first thing that falls out of memory. Both this setting and MAINPROMPT_AS_PING will break if you use double linebreaks anywhere in your main prompt or NSFW prompt as that's the only real way we have to determine where the main prompt stops and the character definition starts. That's a bit flimsier than I'd like but I'll look into other options. Single linebreaks are fine.
 
 ### MAINPROMPT_AS_PING
 If set to true does the same as above, but uses the contents of the main prompt as the PING_MESSAGE instead (see below). This completely replaces the PING_MESSAGE set in the config. Using the main prompt we get from SillyTavern has the advantage that we have access to all placeholders, like `{{char}}` and `{{user}}`, and can use presets to change the PING_MESSAGE instead of having to edit the config every time. If you put an @Claude anywhere in your main prompt or NSFW prompt it will get replaced with the actual Claude ping, same as PING_MESSAGE. The jailbreak from SillyTavern is not included in this as it gets placed apart from the rest of the main prompt. If you want your jailbreak to be in the ping message too, try putting it in the main prompt or NSFW prompt instead.
