 3. Run the shortcut.  "Dat View", the GGPK data viewer UI, should appear.  If you get an error, be sure you're using the latest release of Path of Building Community.
 4. Click `Edit Sources...` to display the "New DAT Source" popup.  Click `New` and enter a name.
 5. Paste the full path to `Content.ggpk` into the "Source from GGPK/Steam PoE path" box and hit `Enter`.  For the stand-alone client, the path must include the file-name.  (Do not put anything in the "Source from DAT files" box unless you have already manually unpacked the relevant files.)
