+# Dank (dms) Greeter
+
+A greeter for [greetd](https://github.com/kennylevinsen/greetd) that follows the aesthetics of the dms lock screen.
+
+## Features
+
+- **Multi user**: Login with any system user
+- **dms sync**: Sync settings with dms for consistent styling between shell and greeter
+- **niri or Hyprland**: Use either niri or Hyprland for the greeter's compositor.
+- **Custom PAM**: Supports custom PAM configuration in `/etc/pam.d/dankshell`
+- **Session Memory**: Remembers last selected session and user
+
+## Installation
+
+The easiest thing is to run `dms greeter install` or `dms` for interactive installation.
+
+Manual installation:
+1. Install `greetd` (in most distro's standard repositories)
+2. Copy `assets/dms-niri.kdl` or `assets/dms-hypr.conf` to `/etc/greetd`
+  - niri if you want to run the greeter under niri, hypr if you want to run the greeter under Hyprland
+3. Copy `assets/greet-niri.sh` or `assets/greet-hyprland.sh` to `/etc/greetd/start-dms.sh`
+4. Edit `/etc/greetd/dms-niri.kdl` or `/etc/greetd/dms-hypr.conf` and replace `_DMS_PATH_` with the absolute path to dms, e.g. `/home/joecool/.config/quickshell/dms`
+5. Edit or create `/etc/greetd/config.toml` 
+```toml
+[terminal]
+# The VT to run the greeter on. Can be "next", "current" or a number
+# designating the VT.
+vt = 1
+
+# The default session, also known as the greeter.
+[default_session]
+
+# `agreety` is the bundled agetty/login-lookalike. You can replace `/bin/sh`
+# with whatever you want started, such as `sway`.
+
+# The user to run the command as. The privileges this user must have depends
+# on the greeter. A graphical greeter may for example require the user to be
+# in the `video` group.
+user = "greeter"
+
+command = "/etc/greetd/start-dms.sh"%
+```
+
+Enable the greeter with `sudo systemctl enable greetd`
+
+## Usage
+
+To run dms in greeter mode you just need to set `DMS_RUN_GREETER=1` in the environment.
+
+```bash
+DMS_RUN_GREETER=1 qs -p /path/to/dms
+```
+
+### Configuration
+
+#### Compositor
+
+You can configure compositor specific settings such as outputs/displays the same as you would in niri or Hyprland.
+
+Simply edit `/etc/greetd/dms-niri.kdl` or `/etc/greetd/dms-hypr.conf` to change compositor settings for the greeter
+
+#### Personalization
+
+Wallpapers and themes and weather and clock formats and things are a TODO on the documentation, but it's configured exactly the same as dms.
+
+You can synchronize those configurations with a specific user if you want greeter settings to always mirror the shell.
+
+```bash
+# For core settings (theme, clock formats, etc)
+sudo ln -sf ~/.config/DankMaterialShell/settings.json /etc/greetd/.dms/settings.json
+# For state (mainly you would configure wallpaper in this file)
+sudo ln -sf ~/.local/state/DankMaterialShell/session.json /etc/greetd/.dms/session.json
+# For wallpaper based theming
+sudo ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /etc/greetd/.dms/dms-colors.json
+```
+
+You can override the configuration path with the `DMS_GREET_CFG_DIR` environment variable, the default is `/etc/greetd/.dms`
+
+It should be writable by the greeter user.
