-> [!CAUTION]
-> (They should add `> [!DISCLAIMER]` fr) I wrote this readme with the same quality as the code, behing this keyboard there's half a brainrotcell left writing what it remembers of this program, so don't take this to seriously, I'm typing as I think without filter lol, but the program works, or should. Also, about any "TODO" in this readme (Or the code), I didn't forget finishing it, I actually don't care. And, references to ~~code~~ **anything** are likely to be outdated, check the commit history to know what I was refering to exactly if you care.

-# Backstory
-I travelling in the summer to visit family with an old laptop that barely supports x86_64, and ly recently added some avx2 instructions I think (I just get invalid op codes), manually building (any previous commit too) didn't work because of something in the `build.zig` file, so out of boredom I decided to craft up my own simple display manager on the only language this thing can handle, ✨C✨ (I hate this and reserve the right for the rust rewrite, actually solid).
-
-I spedrun it, basically did in in 3 days on the same couch on [unhelty back positions (even worse)](https://i.redd.it/4bkje8amisu61.png) while touching *some* grass (:o), and I'm bad af in C, so this is spaghetti code on **another** level. I think it doesn't do almost anything unsafe, I mean, I didn't check allocations and it's capable of reallocating memory until your username uses all memory and crashes the system due to a off by 1 error, but pretty consistent otherwise (Probably).

-# Requirements
-* A computer with unix based system.
-* That system should have the resources neccessary for this program to make sense (Sessions, users...).
-* A compiler (optional, you can compile by hand, but I doubt you want to see the code).
-* Make (Also optional, but does things atomatically, make sure `gcc` and `mkdir -p` work as expected).
 
 # Usage
-Regarding arguments: If a single argument is provided (don't even do `--` or standard parsing...), it passes that argument to `chvt` on startup, used (at least) by the dinit service.
+### Arguments
+If a single argument is provided (don't even do `--` or standard parsing...), it passes that argument to `chvt` on startup, used (at least) by the dinit service.
 
+### Program
 On top of pure intuition:
 * You can change focus of session/user/passwd with up/down arrows.
 * In case arrow keys do nothing on the focused input (Either is empty text or doesn't have more options), it tries to change session and if there's only one session it changes user.
@@ -64,16 +70,22 @@ On top of pure intuition:
 * ESC and then left/right arrows will force to change the option of the focused input, useful if you're editing the current input and arrow keys just move.
 * Editing a predefined option on a user or a shell session, will put you in edit mode preserving the original value, other cases start from scratch.

 # Configuring
 Copy any `.ini` file from [`themes/`](./themes/) (`default.ini` will always be updated) to `/etc/lidm.ini` and/or configure it to your liking. Also, don't place empty lines (for now).
 
-Also configurable colors are just gonna be put inside `\x1b[...m`, ofc you can add an m to break this and this can f* up really bad or even make some nice UI effect possible, but please don't, you should also be able to embed the `\x1b` byte in the config as I won't parse escape codes, I think that the parser is just gonna grab anything in the config file from the space after the `=` (yes, I'ma enforce that space, get good taste if you don't like it) until the newline, you can put any abomination in there.

 The default fg style should disable decorators set up in other elements (cursive, underline... it's just adding 20 to the number btw, so if cursive is 4 (iirc), disabling it is 24).
 
-# Contributing
-Don't do this to yourself, but you can ofc, you can also fork or whatever (make sure to comply with GNU's GPLv3), but I want to do the rust rewrite 😡 (after it, I'll leave this around in case somebody with ancient hardware needs it, or if somebody wants to port it for a microwave...)
+> [!TIP]
+> If you don't like seeing an element, you can change the fg color of it to be the same as the bg, making it invisible.
 
-This is also GPLv3 bcs I was too lazy to look for the "do anything I don't care" license, also it's funny legally trapping people into FOSS. **EDIT:** just realized ly uses it and I coudl've just copied it :(, idk how bad GPLv3 respect to changing license and I *could* rebase but that never goes well, so I'll consult my lawyer (chatGPT) later.

 * KillerTofus, [made the AUR package](https://github.com/javalsai/lidm/pull/2)! Saved me from reading the Arch Wiki 💀.
+* DeaDvey, the most awesomest of all, did some pretty HARDCORE gramer cheking. (and trolling, he wrote that, 33 commits of just readme changes ffs)
+* grialion, made a simple C implementation of `chvt` instead of insecurely relying on `kbd utils`'s command.
+* cerealexperiments_, found a missing newline (had the guts to read the source code, crazy ik)
 * ChatGPT, in times of slow laptops where pages take ages to load, a single tab connected to a bunch of burning cloud GPUs feeding corporate hype is all you need to get quick answers for your questions, as long as you know how to filter AI crap ofc.

-# Milestones
-* If this ~~video~~ **repo** gets to 100 ~~likes~~ **stars**, I'll make an arch aur package and properly document installation on multiple init systems.

+# AUR Packages
+These files are just for reference, I'll manually edit and publish them, at least until I automate it with github actions (like updating version automatically on a release).
+
+There are three packages that follow standard conventions:
+* [`lidm`](https://aur.archlinux.org/packages/lidm): Builds latest release (manually updated per release basis)
+* [`lidm-bin`](https://aur.archlinux.org/packages/lidm-bin): Fetches latest release binary (compiled by GitHub Actions, also updated per release)
+* [`lidm-git`](https://aur.archlinux.org/packages/lidm-git): Fetches latest commit and builds it (should be updated automatically)
+
+> [!IMPORTANT]
+> None of those packages include the service files, I'm considering automatically detecting it on the package function or providing it as separate services (standard practice again).
+>
+> Depending on how good these packages go (my first packages :P) I'll make service ones too.
+
+## Services
+Summary of what to do to install service files anyways:
+* **systemd:** Copy `assets/services/systemd.service` to `/etc/systemd/system/lidm.service` and enable the service (`systemctl enable lidm`)
+* **dinit:** Copy `assets/services/dinit` to `/etc/dinit.d/lidm` and enable the service (`dinitctl enable lidm`)

+# Contributing
+
+Contributions are welcome! Here's how you can help:
+
+- [Contributing code](#code)
+- [Reporting issues](#issues)
+
+## Code
+
+For small fixes or incremental improvements simply fork the repo and follow the process below. For larger changes submit an [RFC:](RFC.md)
+1. [Fork](https://help.github.com/articles/fork-a-repo/) the repository and [clone](https://help.github.com/articles/cloning-a-repository/) your fork.
+
+2. Start coding!
+    - Configure clangd LSP by generating `compile_commands.json` (e.g. `bear -- make` or `compiledb make`)
+    - Implement your feature.
+    - Check your code works as expected.
+    - Run the code formatter: `clang-format -i $(git ls-files "*.cpp" "*.h")`
+
+3. Commit your changes to a new branch (not `master`, one change per branch) and push it:
+    - Commit messages should:
+        - Header line: explain the commit in one line (use the imperative)
+        - Be descriptive.
+        - Have a first line with less than *80 characters* and have a second line that is *empty* if you want to add a description.
+
+4. Once you are happy with your changes, submit a pull request.
+     - Open the pull request.
+     - Add a short description explaining briefly what you've done (or if it's a work-in-progress - what you need to do)
+
+## Issues
+
+1. Do a quick search on GitHub to check if the issue has already been reported.
+2. [Open an issue](https://github.com//javalsai/lidm/issues/new) and describe the issue you are having - you could include:
+     - Screenshots.
+     - Ways to reproduce the issue.
+     - Your lidm version.
+     - Your platform (e.g. arch linux or Ubuntu 15.04 x64)
+
+After reporting you should aim to answer questions or clarifications as this helps pinpoint the cause of the issue.
