-- [Helldivers 2 Mod Manager CLI](#helldivers-2-mod-manager-cli)
+Helldivers 2 Mod Manager CLI is a command line interface for managing Helldivers 2 mods. Since there is no Linux mod manager available and I like being a nerd by using CLI tools instead of GUIs, this project was born.

-### Shortcuts
+## Compatibility
-
+
-You can use the short form of commands to save some time. The shortcuts are:
+The script is developed and tested on Arch Linux, but it should work on other Linux distributions as well. If you encounter any issues, please open an issue on the repository.
-
+
-- `i` for `install`
+Status of platforms:
-- `u` for `uninstall`
+
-- `e` for `enable`
+- Linux :white_check_mark:
-- `d` for `disable`
+- Steam Deck - untested (should work) :grey_question:
-- `l` for `list`
+- Windows - WSL :white_check_mark:
-- `ex` for `export`
+
-- `im` for `import`
+> The script works on WSL, but you need to specify the path to the Helldivers 2 mods directory manually, to find your Windows partition head to `/mnt/` and from there go to your Helldivers 2 data directory, on a typical install it should be on `/mnt/c/Program\ Files\ \(x86\)/Steam/steamapps/common/Helldivers\ 2/data`. You also need to have `unzip` installed, which can be done by running `sudo apt install unzip`.
-- `r` for `reset`
+
-
+## Advanced usage
-### Exporting and importing
+
-
+### Shortcuts
-You can export all installed mods to a zip file and import mods from the same file. This can be useful for sharing mods with others or for backing up your mods. The zip file will be saved in the current directory.

+You can use the short form of commands to save some time. The shortcuts are:
-```bash
+
-h2mm export modpack1.zip
+- `i` for `install`
-h2mm import modpack2.zip
+- `u` for `uninstall`
-```
+- `e` for `enable`
-
+- `d` for `disable`
-### Resetting all installed mods
+- `l` for `list`
-
+- `ex` for `export`
-You can reset all installed mods by running the following command. This will remove all installed mods and the database, in case things go wild.
+- `im` for `import`
-
+- `mc` for `modpack-create`
-```bash
+- `ms` for `modpack-switch`
-h2mm reset
+- `ml` for `modpack-list`
-```
+- `md` for `modpack-delete`
-
+- `mo` for `modpack-overwrite`
-### Database location and details
+- `mr` for `modpack-reset`
-
+- `r` for `reset`
-The database is stored in the `Helldivers 2` install directory, under the `data` folder with the name `mods.csv`, where the mods are also installed. The database is a simple CSV file which you can use to manually manage mods if needed, you can mostly use it to rename or reorder mods.
+
-
+### Modpacks support
-## Contributing
+
-
+You can set up modpacks by using the `modpack-*` commands. This allows you to quickly change between a set of mods. For more information, check the help message.
-Feel free to contribute to this project by creating a pull request or opening an issue.

-## Planned features

-
+# install, enable, disable other mods...
-- [x] Check for mod updates
+h2mm modpack-create "Modpack 2"
-- [x] Enable/disable mods
+h2mm modpack-switch "Modpack 1"
-- [ ] Easier way to change mod presets
+```
-- [ ] Find a way to make use of `manifest.json` and simplify installing variants
+
-- [x] [DEV] Change to `.tar.gz` for exporting and importing
+### Exporting and importing
-- [x] [DEV] Provide fixes for breaking updates
+
-- [ ] [DEV] Optimize code - throw errors in 1 line
+You can export all installed mods to a zip file and import mods from the same file. This can be useful for sharing mods with others or for backing up your mods. The archive file (`.tar.gz`) will be saved in the current directory.
-- [ ] [DEV] Rewrite some code to be more readable

+h2mm export modpack1.zip
+h2mm import modpack2.zip
