-### Basic usage
+### Usage
+
+To find out how to use a command, you can run `h2mm <COMMAND> --help`.
 
 #### Install mod(s)
 
 ```bash
 h2mm install /path/to/mod.zip
-h2mm install /path/to/mod/files
+h2mm install /path/to/mod/directory/
 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]  
+> It's better to be in the directory where the mod files are located, so you don't have to specify the full path. For mod downloads, you can do `cd ~/Downloads` and then run the command.
-> If the mod has more than 1 variant, you need to install the one you want by unarchiving it separately and providing the directory.
+>
-
+> Also, use the Tab key to autocomplete the file names, as it will help you escape special characters likes spaces or quotes.
-#### 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
+h2mm list -v # verbose mode
 ```
 
+#### Uninstall a mod
+
+```bash
+h2mm uninstall -n "Example mod"
+h2mm uninstall -i 3 # get the index from the list command
+```
+
+#### Enable/disable mods
+
+```bash
+h2mm enable -n "Example mod"
+h2mm enable -i 3
+h2mm disable -n "Example mod"
+h2mm disable -i 3
+```
+
+#### Updating the script
+
+```bash
+h2mm update
+```
+
+## Nexus Mods integration
+
+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:
+
+```bash
+h2mm nexus-setup
+```
+
+You will be walked through the setup process, which will ask you for your Nexus Mods API key and your preferred terminal.

 ## Compatibility

-## 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.
