 # ClickUp <-> Phabricator / Phorge bot
 
 Bot to help migration from ClickUp to Phabricator / Phorge (and vice-versa honestly).
 
 ## Available features
 
 * automatically import new ClickUp Tasks in Phabricator (with title, description)
     * automatically update the ClickUp Task to mention the Phabricator Task URL
     * automatically update the Phabricator Task to mention the ClickUp Task URL
     * automatically assign the right Phabricator Tag (associated to the corresponding ClickUp folder)
 * automatically import new Phabricator Tasks in ClickUp (and keeping its ClickUp parent)
 * automatically import new ClickUp Task comments into their related Phabricator Task (and vice-versa)
+* automatically update the ClickUp Task when a commit closes a Task from Phabricator
 * automatically import new Phabricator Task owner when set from ClickUp
 * automatically update the Phabricator Task status when changed from ClickUp (and vice-versa)
 * automatically update the Phabricator Task title when changed from ClickUp
 * automatically create (and attach) a Phabricator parent Task if a ClickUp task has a parent task
