+This is a very basic mod manager for 7 Days to Die on Linux.
+
+## Dependencies
+
+This program requires:
+
+- Python 3.7 or newer
+- Tcl/Tk (python-tk on Debian, tk on Arch)
+
+## General Usage
+
+This mod manager works by storing your mods in a separate directory outside of
+your 7 Days to Die installation, then creating or breaking symlinks to the
+individual mods from the `Mods` folder within your 7 Days to Die installation
+to enable and disable them, respectively.
+
+Upon first use, you will be prompted for the locations of your mods folder and
+7 Days to Die installation. After configuring these, they are stored in
+`seven-mods.cfg`.
+
+seven-days also allows the user to create separate mod profiles. If, for
+instance, you frequent a multiplayer server with a certain set of mods, but
+have a different prefered set of mods for single player, then you could create
+two mod profiles, called `multiplayer` and `singleplayer`, for instance.
+Loading a mod profile will instantly change the enabled mods to the ones that
+were enabled when the profile was last saved.
+
+## CLI Version
+
+The main source file for the CLI version is `seven-mods.py`. General usage is:
+
+`python seven-mods.py <command> <args...>`
+
+The available commands are:
+
+- `list`: show a listing of all installed mods. Disabled mods appear in red.
+Enabled ones appear in green, and are followed by an asterisk (`*`).
+- `enable`: enable mods. A list of mod names can be given, separated by spaces.
+The mod names are the names of their respective folders, *not* the names listed
+in their respective `ModInfo.xml` files. Alternatively, to enable all mods,
+simply type `-a` rather than listing them all out.
+- `disable`: disable mods. Arguments are the same as for `enable`, including
+`-a` to disable all mods.
+- `toggle`: toggles mods on or off. Does *not* support `-a`.
+- `save`: saves the currently enabled mods to a profile. The only argument
+that should be given is the name of the profile to save. If the profile already
+exists, then it will be overwritten.
+- `load`: sets the enabled mods to those defined by the given profile.
+
+Tip: If you run the script from the directory in which you store your mods,
+then bash autocompletion works for mod names - hence why it uses the ugly
+folder names rather than the nice `ModInfo.xml` names.
+
+Warning: Due to Python's built-in `input()` function being jank on Linux, it
+may be easier to start out by just using the `list` command, accepting the
+defaults (by just striking the return key without typing anything), then editing
+the `seven-mods.cfg` file later. This is not ideal, so a better solution may
+come in the future.
+
+## GUI Version
+
+A GUI version that uses tkinter is planned, but not yet ready. It'll be great
+though!
