Before you start, make sure you have:
- A device to install RetroDECK on.
- Related BIOS & Firmware ready.
- Game backups of various formats or purchased titles ready to play.
### Step 1: Installation

### Step 2: Place BIOS & Firmware
Place BIOS & Firmware files in the `retrodeck/bios/` directory.
**Read up on:**
[BIOS/Firmware](../wiki_management/bios-firmware.md)
### Step 3: Place ROMs and Games
RetroDECK follows ES-DE's folder structure.
Place ROM files in their corresponding system directory inside the `retrodeck/roms/` folder (the location of the `retrodeck/roms/` folder depends on your installation location choice).
**Example:**
You have an example NES game called: `ExampleNESGame.nes`
- Place `ExampleNESGame.nes` in the `retrodeck/roms/nes/` folder.
- The result should be: `retrodeck/roms/nes/ExampleNESGame.nes`

### Step 5: Playing the Games
Launch RetroDECK via Steam or by itself. The systems you placed ROM files for should be shown and playable.
**Example:**
The NES category should now be shown in the ES-DE Frontend with `ExampleNESGame.nes` from `Step 3`.
