## How do I add mods?
**Note:**

- `TITLEID` is different for every game.
On the Steam Deck this could be easier to do in `Desktop Mode`.

2. Open up Citra inside `RetroDECK Configurator` by pressing `Open Emulator` - `Citra`.
3. Right click on the game you want to add mods into.
4. Click on `Open Mods Location`.

6. Quit Citra
### From the mod folder directly

**Example:**
* You have a `.zip` file for a game that contains the `/load/textures/0000001000` folders.
* All you need to do is take the TITLEID folder: `0000001000` and put it into `~/retrodeck/texture_packs/citra/`
* So the end result looks like: `~/retrodeck/texture_packs/citra/0000001000`
