+# The RetroDECK .doom file
+
+The RetroDECK `.doom` file is a feature for easy loading of doom files with mods.
+
+## The RetroDECK .doom Parser
+
+The `.doom` parser will look for any of the core doom iwads files that could be required to run a DOOM mod in the `/retrodeck/roms/doom/` directory.
+
+Here is what files it is currently looking for:
+
+```

+ )
+```
+
+### What are core doom iwads?
+
+It is just how the RetroDECK Team defines the [IWADS](https://doomwiki.org/wiki/IWAD) Gzdoom is looking for to be able to run.
+
+- DOOM1.WAD - Doom 1 alternate name
+- DOOM.WAD - Doom 1
+- DOOM2.WAD - Doom 2
+- DOOM2F.WAD - Doom 2 French
+- DOOM64.WAD - Doom 64
+- TNT.WAD - Final Doom - TNT: Evilution
+- PLUTONIA.WAD - Final Doom - The Plutonia Experiment
+- HERETIC1.WAD - Heretic - Shareware Version
+- HERETIC.WAD - Heretic: Shadow of the Serpent Riders
+- HEXEN.WAD - Hexen
+- HEXDD.WAD - Hexen: Deathkings of the Dark Citadel (Needs HEXEN.WAD as well to be played)
+- STRIFE0.WAD - Strife: Quest for the Sigil - Demo
+- STRIFE1.WAD - Strife: Quest for the Sigil - Commercial / Veteran Edition
+- VOICES.WAD - Extra Voices for Strife: Quest for the Sigil - Commercial / Veteran Edition
+- CHEX.WAD - Chex Quest

+- HACX.WAD - Hacx
+- freedoom1.wad - Freedoom: Phase 1
+- freedoom2.wad - Freedoom: Phase 2
+- freedm.wad - FreeDM
+- doom_complete.pk3 - WadSmoosh combined file
+
+### What is doom_complete.pk3?
+
+`doom_complete.pk3` is a file made by [WadSmoosh](https://jp.itch.io/wadsmoosh). It can combine all of the "DOOM + DOOM 2 + Official addons" into one file where you can select from all the campaigns without needing to load each separate wad.
+
+## Recommended folder structure in retrodeck/roms/doom?
+
+WIP
+
+## What is the .doom file and how do you create it?
+
+The `.doom` file is just an empty text file that is populated with the exact filenames of the files you want to load and in what order from top to bottom.
+
+You should name the `.doom` file so you understand what it is, for example: `Project Brutality.doom`.
+
+Each line represent one file, as long as the mods are compatible with each other you can add how lines as you want.
+
+### What is the recommended load order of the .doom file?
+
+The general guidelines on most mod pages is:
+
+- Map WAD (Like DOOM2.WAD or DOOM.WAD).
+- Bigger mods like Project Brutality.
+- Any other mini-mods like huds, graphics or other tweaks.
+
+But this can be different, check the where you download the mods if they have any recommended order requirement.
+
+## Project Brutality .doom example:
+
+In this example you have already downloaded a bunch of mods and have the core doom files already under the `/retrodeck/roms/doom/` folder.
+
+You want to play [Project Brutality](https://www.moddb.com/mods/project-brutality) on DOOM 2 levels.
+
+On the ModDB Page of Project Brutality they say that the order to run it is:
+
+
+All you need to do is create an empty file called `Project Brutality.doom` in `/retrodeck/roms/doom/`.
+
+Each line the the file will be the order the mods are loaded, make each lines value is called exactly what the file name is called.
+
+So in the case of `Project Brutality.doom`
+
+The contents will look like this
+
+```
+DOOM2.WAD
+PB_Staging_9f2561c.pk3
+```
+
+The DOOM2.WAD is first loaded then the Project Brutality PB_Staging_9f2561c.pk3 file and the game starts.
+
+`Project Brutality.doom` is now accessible from the ES-DE interface.
+
+
+### Another Example: Doom Infinite
+
+[Doom Infinite](https://www.moddb.com/mods/doom-infinite)
+
+Create the `Doom Infinite.doom` file in `/retrodeck/roms/doom/`
+
+```
+DOOM2.WAD
+DOOM_Infinite_DEMO_0978_6.pk3
+```
+
+## Customize the RetroDECK .doom files
+
+You can customize it how you wish with the above examples as a guideline.
+There is nothing stopping you from adding more mods or create an infinite amount of `.doom` files.
+
+Maybe you want to have Project Brutality with DOOM and Doom 2 as separate entries in the ES-DE interface.
+
+
+
+`Project Brutality DOOM 2.doom`
+
+```
+DOOM2.WAD
+PB_Staging_9f2561c.pk3
+```
+
+
+`Project Brutality DOOM.doom`
+
+```
+DOOM.WAD
+PB_Staging_9f2561c.pk3
+```
+
+Want to have more minor mods into Project Brutality?
+Just keep adding the lines with the mod file names how many you want.
+
+Name the .doom file so you understand what it is and you are done:
+
+- `Project Brutality - The Ultimate Collection.doom`
+- `Project Brutality - But with Horses.doom`
+- `Project Brutality - Chex Quest with a Vengeance.doom`
+
+It is that easy.
