+## How to Dynamically Assign Team Messages
+
+This plugin also allows system admins and team admins to change the team message of an appropriate team through a slash command, rather than adjusting the config.json.
+
+We have provided three options that are formatted identically to the channel welcomes:
+- `/welcomebot get_team_welcome` - prints the current team's welcome message if the dynamic message or the config.json message exists.
+- `/welcomebot set_team_welcome [welcome message]` - sets the current team's welcome message to the one defined in the slash command.
+- `/welcomebot delete_team_welcome` - deletes the current team's welcome message. This however does NOT delete any messages set inside of the config.json.

 ## Development
 
 This plugin contains a server and webapp portion.
