-h2mm enable "Example mod"
+>
-h2mm enable -i 1 # enable mod with index 1
+> Also, use the Tab key to autocomplete the file names, as it will help you escape special characters likes spaces or quotes.

-h2mm disable -i 1 # disable mod with index 1
+#### List installed mods
-```
+
-
+```bash
-#### List installed mods

+```
-```
+
-
+#### Enable/disable mods
-## Compatibility
+
-
+```bash
-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.
+h2mm enable -n "Example mod"
-
+h2mm enable -i 3
-Status of platforms:
+h2mm disable -n "Example mod"
-
+h2mm disable -i 3
-- Linux :white_check_mark:
+```
-- Steam Deck :white_check_mark:
+
-- Windows - WSL :white_check_mark:
+#### Updating the script
-
+
-> 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`.
+```bash
-
+h2mm update
-## Advanced usage
+```
-
+
-### Shortcuts
+## Nexus Mods integration
-
+
-You can use the short form of commands to save some time. The shortcuts are:
+Nexus Mods integration allows you to use the 1-click install feature of Nexus Mods (with the "Vortex" or "Mod manager download" buttons). You can set up Nexus Mods integration by running the following command:
-
+
-- `i` for `install`
+```bash
-- `u` for `uninstall`
+h2mm nexus-setup
-- `e` for `enable`
+```
-- `d` for `disable`
+
-- `l` for `list`
+You will be walked through the setup process, which will ask you for your Nexus Mods API key and your preferred terminal.
-- `ex` for `export`
+
-- `im` for `import`
+## Compatibility
-- `mc` for `modpack-create`
+
-- `ms` for `modpack-switch`
+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.
-- `ml` for `modpack-list`
+
-- `md` for `modpack-delete`
+Status of platforms:
-- `mo` for `modpack-overwrite`
+
-- `mr` for `modpack-reset`
+- Linux :white_check_mark:
-- `r` for `reset`
+- Steam Deck :white_check_mark:
-- `up` for `update`
+- Windows - WSL :white_check_mark:
-
+
-### Modpacks support
+> 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`. Nexus Mods integration is not supported on WSL.
-
+
-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.
+## Contributing
-
+
-```bash
+Feel free to contribute to this project by creating a pull request or opening an issue.
-h2mm modpack-create "Modpack 1"
-# install, enable, disable other mods...
-h2mm modpack-create "Modpack 2"
-h2mm modpack-switch "Modpack 1"
-```
-
-### Exporting and importing
-
-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.
-
-```bash
-h2mm export modpack1.zip
-h2mm import modpack2.zip
-```
-
-### Resetting all installed mods
-
-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.
-
-```bash
-h2mm reset
-```
-
-### Database location and details
-
-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.
