+### I made a command. It's supposed to output formatting with spaces and tabs?
+By default, PBot collapses adjacent whitespace in command output. This is intended to
+reduce visual noise in IRC channels.
+
+If your command is registered by a plugin, use the [`cmdset`](Admin.md#cmsdset) command
+to set the `preserve_whitespace` [command metadata](Admin.md#command-metadata-list) to
+control this behavior.
+
+If your command is a command-line module, use the [`factset`](Factoids.md#factset) command
+to set the `preserve_whitespace` [factoid metadata](Factoids.md#factoid-metadata-list) instead.
