-
-> [!CAUTION]
-> I encourage you to read the manual installation steps to understand what will get installed in your computer by this package.
-
-# Installing from Source
-
-Firstly, you'll need to build the package, this also includes man pages, default config, themes and other files you might need.
-
-To build it you only need to have some basic packages (should come pre-installed in almost all distros): `make`, `gcc` or another `gcc`ish compiler, and libpam headers. If it builds, it surely works anyways.
-
-```sh
-git clone https://github.com/javalsai/lidm.git
-cd lidm
-make # 👍
-```
-
-> [!NOTE]
-> There's pre-built binaries on the [releases tab](https://github.com/javalsai/lidm/releases) too.
-
-Then you can install the files onto your filesystem with:
-
-```sh
-make install
-```
-
-And additionally, to install service files (start-up behavior). <sup>[more docs](./assets/services/README.md)</sup>
-
-```sh
-# automatically detects your init system
-# and install service file (for tty7)
-make install-service
-
-# or if you don't like autodetection
-make install-service-systemd # systemd
-make install-service-dinit # dinit
-make install-service-runit # runit
-make install-service-openrc # openrc
-make install-service-s6 # s6
-```
-
-# AUR
-
-[AUR packages](https://aur.archlinux.org/packages?K=lidm\&SeB=n) will automatically install most files.
-
-> [!CAUTION]
-> [service files](./assets/pkg/aur#services) have to be manually installed by now.
-
-# Nix Flake
-
-You can install by doing
-
-```sh
-nix profile install github:javalsai/lidm
-```
-
-or try it out without installing by:
-
-```sh
-nix run github:javalsai/lidm
-```
-
-> [!CAUTION]
-> This doesn't include [service files](./assets/pkg/aur#services) neither

 ## Features
 
-* Simple as C, you only need a C compiler and standard unix libraries to build this.
-* Fully customizable, from strings, including action keys, to colors (I hope you know ansi escape codes)
-* Automatically detects xorg and wayland sessions, plus allowing to launch the default user shell (if enabled in config)
-* Starts with many init systems (systemd, dinit, runit, openrc and s6).

+# PAM
+
+If your distribution does not use the standard PAM service name `login` (`/etc/pam.d/login`) for its PAM services or if you want to use another PAM file, simply set the `LIDM_PAM_SERVICE` env variable to your PAM service name.
+
+When the env variable is empty it defaults to the `login` PAM service or whatever fallback your distribution packager has defined during compilation.

+
+> [!CAUTION]
+> I encourage you to read the manual installation steps to understand what will get installed in your computer by this package.
+
+# Installing from Source
+
+Firstly, you'll need to build the package, this also includes man pages, default config, themes and other files you might need.
+
+To build it you only need to have some basic packages (should come pre-installed in almost all distros): `make`, `gcc` or another `gcc`ish compiler, and libpam headers. If it builds, it surely works anyways.
+
+```sh
+git clone https://github.com/javalsai/lidm.git
+cd lidm
+make # 👍
+```
+
+> [!NOTE]
+> There's pre-built binaries on the [releases tab](https://github.com/javalsai/lidm/releases) too.
+
+Then you can install the files onto your filesystem with:
+
+```sh
+make install
+```
+
+And additionally, to install service files (start-up behavior). <sup>[more docs](./assets/services/README.md)</sup>
+
+```sh
+# automatically detects your init system
+# and install service file (for tty7)
+make install-service
+
+# or if you don't like autodetection
+make install-service-systemd # systemd
+make install-service-dinit # dinit
+make install-service-runit # runit (/etc/sv)
+make install-service-runit-etc # runit (/etc/runit/sv)
+make install-service-openrc # openrc
+make install-service-s6 # s6 (/etc/sv)
+make install-service-s6-etc # s6 (/etc/s6/sv)
+
+#  For runit and s6, some distros (e.g. Artix) like to put it in /etc/<init>/sv
+# to better isolate their packages while other distros (e.g. Void) just put it
+# in /etc/sv
+```
+
+# AUR
+
+[AUR packages](https://aur.archlinux.org/packages?K=lidm&SeB=n) will automatically install most files.
+
+> [!CAUTION]
+> [service files](./assets/pkg/aur#services) have to be manually installed by now.
+
+# Nix Flake
+
+You can install by doing
+
+```sh
+nix profile install github:javalsai/lidm
+```
+
+or try it out without installing by:
+
+```sh
+nix run github:javalsai/lidm
+```
+
+> [!CAUTION]
+> This doesn't include [service files](./assets/pkg/aur#services) neither
+
+# Nix Module
+
+<details>
+<summary>Sidenote</summary>
+
+The nix module lacks on several aspects, if you know much about nix and know
+how to improve this package, feel free to open an issue or a PR to help. The
+nix package maintainer position is open too.
+
+</details>
+
+Lidm includes a nix module in `assets/pkg/nix/module.nix` that you can add
+(along the included nix files) and import in your `configuration.nix`.
+
+Once imported you'll need to add:
+
+```nix
+services.displayManager.enable = true;
+systemd.services.lidm.enable = true;
+```
+
+Optionally, you can configure it setting `services.lidm.config`. You can either
+pass:
+
+- A string to copy the config from a theme in `themes/` with said name
+  (**name**, e.g `"cherry"`).
+- An attribute tree with the same names as the config file, e.g:
+
+```nix
+with config.lidm.keysEnum; {
+    strings = {
+        f_poweroff = "custom_poweroff";
+    };
+
+    behavior = {
+        include_defshell = true;
+        source = [
+            "path1"
+            "path2"
+        ];
+    };
+
+    functions = { poweroff = F1; };
+
+    # etc...
+};
+```
+
+> _it's not necessary to cover all keys and anything can be put there, even if it's not valid config_

+This is a guide listing all possible options packagers have to tweak behavior of lidm and the extra stuff to package.
+
+# Components
+
+If you want to package lidm for a distribution you have to package the binary and:
+
+- Man pages ([`../assets/man/`](../assets/man/))
+- Service files ([`../assets/services/`](../assets/services/))
+- PAM (see [#preprocessor-defines](#preprocessor-defines))
+- And optionally you can include some default themes in `/usr` ([`../themes/`](../themes/))
+
+# Preprocessor Defines
+
+Most of the behavior that can be tweaked using preprocessor `#define`s, to include some simply add `CPPFLAGS+='-D{{name}}={{value}}'` to your `make` command. e.g:
+
+```sh
+make \
+    CPPFLAGS+='-DSESSIONS_XSESSIONS=\"/var/empty\"' \
+    CPPFLAGS+='-DSESSIONS_WAYLAND=\"/var/empty\"'
+```
+
+The list of possible `#define`s is:
+
+| Name                   | Default                         | Description                                                                | Env Override?            |
+| ---------------------- | ------------------------------- | -------------------------------------------------------------------------- | ------------------------ |
+| `PAM_SERVICE_FALLBACK` | `"login"`                       | Name of the default PAM module to use. Defaults to the distro's `"login"`. | Yes (`LIDM_PAM_SERVICE`) |
+| `SESSIONS_XSESSIONS`   | `"/usr/share/xsessions"`        |                                                                            | No                       |
+| `SESSIONS_WAYLAND`     | `"/usr/share/wayland-sessions"` |                                                                            | No                       |
+| `LIDM_CONF_PATH`       | `"/etc/lidm.ini"`               | Path of the default configuration.                                         | Yes (`LIDM_CONF`)        |
+
+# Other Build Settings
+
+## Compiler
+
+Lidm attempts to support being built by `gcc` and `clang` with preference over the first. However, if you wish to take advantage of LLVM's optimizations over GNU's you can change the compiler with `make CC=clang` or try any other compiler.
+
+## Compiler Flags
+
+Compiler flags should be passed with `CFLAGS`, its `-O3 -Wall` by default so adding anything will overwrite this.
+
+## Target Directory
+
+`DESTDIR` can be used to for installation recipes to install on alternative root directories. Along with `PREFIX` (defaults to `/usr`) for systems which don't use the common `/usr` structure. e.g. `make install DESTDIR=$out PREFIX=`
+
+```txt
+$ fd -t f . --base-directory $out
+bin/lidm
+etc/lidm.ini
+share/man/man1/lidm.1
+share/man/man5/lidm-config.5
+```
+
+# Build Recipes for Packaging
+
+To ease most of the installation process there's several `make` recipes to install man pages and service files, I encpurage you to check their source yourself, but:
+
+- `make` / `make lidm`: Builds the app binary.
+- `make install`: Attempts to install the binary, place a default config file in `/etc/lidm.ini` and install the man pages.
+- `make install-service-(systemd|dinit|runit|openrc|s6)(|-etc)`: Just check the source, service files for different init systems and `-etc` variants for alternative paths.
+- `make print-version`: Outputs the current version in the `Makefile` for scripts that might want to extract that info.
+
+You can choose to use these packages or create your own service files / etc. There's are merely suggestions on what to use.
