+The `form_id` part can be given either directly as decimal, or hexadecimal (in this case it is prefixed with `0x`).
+For example: `skyrim.esm/78433` or `skyrim.esm/0x00013261` for the NPC named Beirand in Skyrim Special Edition.
 
 A test run will:
 1. Put the player in god mode (as some NPCs can be hostile or knock the Player).
 2. Disable Combat AI, so that NPCs should not attack player.
 3. Disable Non-combat AI, so that NPCs should not initiate actions.

 1. Execute xEdit, loading all your mods.
 2. Right-click on the left pane and select `Apply filter`.
 3. Check the check-box `Name contains` and enter `J'Zargo` in the text field below.
 4. In the `by Record Signature` list (the middle-one), make sure `NPC_` is selected, then click on the `Filter` button.
 5. In the results shown on the left pane, you see which plugins define or overwrite your NPC (in this case `skyrim.esm`), and if you expand the list you'll see the NPC's form ID (in this case `0001C195`).
