+## Moving Out of Labs
+
+Someday, your labs project may have it's own repository. You can easily move
+all of your Git history to your new repository:
+
+    # cd to labs and checkout your project's branch
+    cd incubator-cordova-labs
+    git checkout my-branch
+
+    # add your new repository as a remote
+    git add remote my-remote <url>
+
+    # currently, my-remote is empty (has no commits)
+
+    # push my-branch to my-remote's master branch
+    git push my-remote my-branch:master
+
+    # now clone your new project (my-remote)
+    cd ..
+    git clone <url>
