-Helldivers 2 Mod Manager CLI is a command line interface for managing Helldivers 2 mods. Since there is no mod manager GUI for Helldivers 2 on Linux yet, this small script aims to provide a simple way to manage mods on Linux.
-
-## Installation
-
-To install/update Helldivers 2 Mod Manager CLI run the following command in your terminal:
-
-```bash
-sh -c "$(curl -fsSL https://raw.githubusercontent.com/v4n00/h2mm-cli/refs/heads/master/install.sh)"
-```
-
-Running this script will require sudo permissions. **DO NOT TRUST** random scripts from the internet. If you want to review the script before running it, check out the mod repository for yourself.
-
-## Usage
-
-The script gets added to `/usr/local/bin/h2mm` and can be used by running `h2mm` in your shell, which will show the help message explaining how to use the script.
-
-```bash
-h2mm
-```
-
-### Available commands
-
-- `install` - Install a mod with files
-- `uninstall` - Uninstall a mod by name
-- `list` - List all installed mods
-- `export <zip_name>` - Export installed mods to a zip file
-- `import <zip_name>` - Import mods from a zip file
-- `reset` - Reset all installed mods
-- `help` - Display the help message
-
-### Basic usage
-
-#### Install a mod
-
-```bash
-h2mm install /path/to/mod.zip
-h2mm install /path/to/mod/files
-h2mm install -n "Example mod" mod.patch_0 mod.patch_0.stream # -n is mandatory when using files
-h2mm install -n "Example mod" mod* # using a wildcard to include all files
-```
-
-Important: If the mod has more than 1 variant, you need to install the one you want by unarchiving it separately.
-
-#### Uninstall a mod
-
-```bash
-h2mm uninstall "Example mod"
-h2mm uninstall -i 1 # uninstall mod with index 1
-```
-
-#### List installed mods
-
-```bash
-h2mm list
-```
-
-## Advanced usage
-
-### Shortcuts
-
-You can use the short form of the commands to save some time. The shortcuts are:
-
-- `i` for `install`
-- `u` for `uninstall`
-- `l` for `list`
-- `ex` for `export`
-- `im` for `import`
-- `r` for `reset`
-
-### 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 zip file will be saved in the current directory.
-
-This will serve as either a backup or a way to have multiple mod setups.
-
-```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.

-## Planned features
-
-- [ ] ! Enable/disable mods
-- [ ] !! Easier way to change mod presets
-- [ ] !! Change to `.tar.xz` for exporting and importing
-- [ ] !!! Find a way to make use of `manifest.json` and simplify installing variants
+# 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.
+
+This script is complete, the version will always [remain at 0.x.x](https://0ver.org/)
+
+## Installation and updating
+
+To install/update Helldivers 2 Mod Manager CLI run the following command in your terminal:
+
+```bash
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/v4n00/h2mm-cli/refs/heads/master/install.sh)"
+```
+
+> [!CAUTION]
+> Running this script will require sudo permissions. **DO NOT TRUST** random scripts from the internet. If you want to review the script before running it, check out the mod repository for yourself.
+
+If for some reason, the installation command doesn't work you can:
+1. Go to https://raw.githubusercontent.com/v4n00/h2mm-cli/refs/heads/master/install.sh
+1. Right click -> Save page as...
+1. Go to your downloads folders `cd ~/Downloads`
+1. Give the script execution permissions `chmod +x install.sh`
+1. Run the script `./install.sh`
+
+## Usage
+
+The script gets added to `/usr/local/bin/h2mm` and can be used by running `h2mm` in your shell, which will show the help message explaining how to use the script.
+
+```bash
+h2mm
+```
+
+### Available commands
+
+- `install` - Install a mod by the file provided (directory, zip, patch).
+- `uninstall` - Uninstall a mod by name (or index).
+- `list` - List all installed mods.
+- `enable` - Enable a mod by name (or index).

+
+### Basic usage
+
+#### Install mod(s)
+
+```bash
+h2mm install /path/to/mod.zip
+h2mm install /path/to/mod/files
+h2mm install /path/to/mod.zip /path/to/mod2.zip /path/to/mod/files
+h2mm install -n "Example mod" mod.patch_0 mod.patch_0.stream # -n is mandatory when using files
+h2mm install -n "Example mod" mod* # using a wildcard to include all files
+```
+
+> [!NOTE]  
+> If the mod has more than 1 variant, you need to install the one you want by unarchiving it separately and providing the directory.
+
+#### Uninstall a mod
+
+```bash
+h2mm uninstall "Example mod"
+h2mm uninstall -i 1 # uninstall mod with index 1
+```
+
+#### Enable/disable mods
+
+```bash
+h2mm enable "Example mod"
+h2mm enable -i 1 # enable mod with index 1
+h2mm disable "Example mod"
+h2mm disable -i 1 # disable mod with index 1
+```
+
+#### List installed mods
+
+```bash
+h2mm list
+```
+
+## Compatibility
+
+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.
+
+Status of platforms:
+
+- Linux :white_check_mark:
+- Steam Deck - untested (should work) :grey_question:
+- Windows - WSL :white_check_mark:
+
+> 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`.
+
+## Advanced usage
+
+### Shortcuts
+
+You can use the short form of commands to save some time. The shortcuts are:
+
+- `i` for `install`
+- `u` for `uninstall`
+- `e` for `enable`
+- `d` for `disable`
+- `l` for `list`
+- `ex` for `export`
+- `im` for `import`
+- `mc` for `modpack-create`
+- `ms` for `modpack-switch`
+- `ml` for `modpack-list`
+- `md` for `modpack-delete`
+- `mo` for `modpack-overwrite`
+- `mr` for `modpack-reset`
+- `r` for `reset`
+
+### Modpacks support
+
+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.
+
+```bash
+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.
