+## Build Instructions ##
+
+Post-checkout instructions for Windows, necessary to convert the assets symlink to a Windows symlink:
+
+From git bash, inside the cloned project root:
+
+    $ rm WordPressEditor/src/main/assets
+    $ git ls-files --deleted -z | git update-index --assume-unchanged -z --stdin
+
+Then, from a Windows command prompt:
+
+    mklink /D [PROJECT_ROOT]\WordPressEditor\src\main\assets %PROJECT_ROOT%\libs\editor-common\assets
+
+Finally, update [PROJECT_ROOT]\.git\info\exclude to ignore the symlink locally:
+
+    # assets symlink
+    WordPressEditor/src/main/assets
