+## Deprecation notice
 
-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.
+> [!Caution]
+> This project is deprecated as of 30/09/2025 in favor of [Arsenal](https://www.nexusmods.com/helldivers2/mods/4664)'s 0.30.0 release, a GUI mod manager that supports every feature of Helldivers 2 Mod Manager CLI and more, on Linux.
+
+**Thank you for the support up until now and make sure to check out Arsenal!**
+
+## Overview
+
+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.
 
 ## Installation
 
-To install/update Helldivers 2 Mod Manager CLI run the following command in your terminal:
+Pre-requisites:
+
+- The `unzip` package must be installed for ZIP archives.
+- The `unarchiver` package is recommended for RAR and 7Z archives.
+
+To install Helldivers 2 Mod Manager CLI run the following command in the terminal:
 
 ```bash
-sh -c "$(curl -fsSL https://raw.githubusercontent.com/v4n00/h2mm-cli/refs/heads/master/install.sh)"
+bash -c "$(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.
+The script gets added to `/usr/local/bin/h2mm` (or `$HOME/.local/bin` on Steam Deck) and can be used by running `h2mm` in the shell, which will print the help message along with all available commands.
 
 ```bash
-h2mm
+h2mm --help
 ```
 
-### Available commands
+To find out how to use a command, run `h2mm COMMAND --help`. This is the most up-to-date source of information about the 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
+## Available commands
 
-### Basic usage
+- `install` or `i` - Install a mod by the file provided (directory, zip, patch)
+- `uninstall` or `u` - Uninstall a mod
+- `list` or `l` - List all installed mods
+- `enable` or `e` - Enable a mod
+- `disable` or `d` - Disable a mod
+- `rename` or `r` - Rename a mod
+- `order` or `o` - Change load order for a mod
+- `export` or `ex` - Export installed mods to a zip file
+- `import` or `im` - Import mods from a zip file
+- `modpack` or `m` - Manage modpacks (collections of mods)
+- `nexus-setup` or `ns` - Setup Nexus Mods integration
+- `update` or `up` - Update h2mm to latest version
+- `reset` or `rs` - Reset all installed mods
+- `help` or `h` - Display this help message
 
-#### 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
+## Examples
 
 ```bash
+h2mm install --help
+h2mm install ~/Downloads/mod.zip
+h2mm install ~/Downloads/mod\ files/
+h2mm install a0b1c2d3.patch_0 a0b1c2d3.patch_0.stream -n "Example mod"
 h2mm list
+h2mm uninstall --index 3
+h2mm modpack create "Example modpack"
+h2mm modpack switch "Example modpack"
 ```
 
-## Advanced usage
+> When installing, it is recommended to be in the directory where mod archives are, or to use absolute paths. Use `cd ~/Downloads` to go to the Downloads folder, and run `ls -la` to find the archives to install. Use the Tab key to auto-complete file and folder names, this helps escape spaces and special characters.
+>
+> Use the `--index` flag with commands that normally require a mod name to specify a mod by its index. The index can be obtained with `h2mm list`.
 
-### Shortcuts
+## Nexus Mods integration
 
-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.
+Nexus Mods integration allows the use the 1-click install feature of Nexus Mods (with the "Vortex" or "Mod manager download" buttons). Set up Nexus Mods integration by running `h2mm nexus-setup`. Setup includes providing the Nexus Mods API key and selecting the preferred terminal.
