 # Phabricator QA Mercurial Test Repository
 
 ## Using arc
 
+# NEW CHANGE
+
 The followings steps will configure arcanist for use in dev, stage, and production environments:
 
 1. Clone the following repositories to the same directory on your machine:
 
 ```bash
 $ mkdir ~/phacility; cd ~/phacility
 $ git clone https://github.com/phacility/libphutil
 $ git clone https://github.com/phacility/arcanist
 ```
 
 2. Open your ~/.bash_profile file and add the following:
 
 ```bash
 alias arc='~/phacility/arcanist/bin/arc'
 ```
 
 Doing so will allow you to use the arc command from anywhere on your machine
 
 Don't forget to:
 
 ```bash
 $ source ~/.bash_profile
 ```
 
 3. Connect to your Phabricator account (follow instructions provided):
 
 ```bash
 $ arc install-certificate
 ```
 
 4. Make some changes to files in the repository:
 
 ```bash
 $ hg clone https://hg.mozilla.org/automation/phabricator-qa-dev
 $ cd phabricator-qa-dev
 $ echo "test file" > foo.txt
 $ hg add foo.txt
 $ hg commit -m 'My new file'
 ```
 
 4. Send a diff to Phabricator and create a new revision:
 ```bash
 $ arc diff
 ```
 
 5. To update a revision, just do the same thing:
 
 $ echo "more change" >> foo.txt
 $ hg add foo.txt
 $ hg commit -m "Updated file"
 $ arc diff
 
 6. When your revision has been accepted, push it normally.
 (arc does not have push integration in Mercurial because it can't force
  merges and thus can't guarantee it will be able to do anything useful.)
