-***Project Documentation***
+***(!) This branch does not include packages. It instead includes the tools 
+required to make them. (!)***
 
-(!) Please note that documentation is incomplete and can be very outdated (!)
+***(!) The final packages only install fases box. If you want separate 
+binaries you'll have to compile them yourself. (!)***

+## Building packages
 
-- [Mirrors](docs/MIRRORS.md)
+Please refer to the official documentation of the packaging format you're

-## Goal
-
-The `fases` project tries to provide friendly, functionnal and simple core 
-utilities for a fully functionnal UNIX-like Operating System. It tries to 
-be entirely portable and working on any UNIX-like Operating System and kernel 
-such as OpenBSD and Linux. It also tries to be completly modular and as such 
-one utility should **not** depend on another in order to work. The coreutils 
-are still a work-in-progress.
-The `fases` utilities are currently tested on Artix, Alpine, OpenBSD, OS X and
-FreeBSD. We expect all utilities to work on all systems implementing POSIX 
-due to us using only POSIX-compliant functions.
-
-## Directory structure
+Building a package on Arch Linux and Arch-based OSes is simple. Just run 
+`makepkg`.

-## Licensing
-
-The `fases` project is licensed under 3 separate licenses:
-
-- POSIX core utilities are licensed under the permissive 3-clause BSD license ;
-
-- The documentation, including manpages, are licensed under the FreeBSD 
-documentation license ;
-
-- Non-POSIX utilities such as box and extras are licensed under the copyleft 
-GPLv3 license. The `fases` box binary is also licensed under the GPLv3.
-
-## Chat
-
-The `fases` project has 2 IRC channels hosted on 2 IRC Networks:
-
-- `#fases` on `LibreIRC` ([webchat](https://kiwi.andrewyu.org/#fases)):
-
-server: `irc.andrewyu.org` ;
-
-ssl: `6697` (recommended) ;
-
-plain: `6667`.
-
-- `#fases` on `Libera.Chat` ([webchat](https://web.libera.chat/#fases)):
-
-server: `irc.libera.chat` ;
-
-ssl: `6697` (recommended) ;
-
-plain: `6667`.
-
-Both of these channels are linked so all messages sent in one of them 
-is sent on the other Network.
-
-## Mailing Lists
-
-(!) The ***fases -at- andrewyu -dot- org*** mailing list is going to be 
-deprecated soon in favor of the new 
-***fases-general -at- andrewyu -dot- org*** which includes a new UI and 
-a mail archive that isn't provided by a third-party. Please use that 
-mailing list instead. (!)
-
-The `fases` project also has a mailing list ran by Andrew Yu (thanks!).
-
-The mailing list's address is: 
-***fases-general -at- andrewyu -dot- org*** 
-(
-[subscribe](https://mail.andrewyu.org/mailman/listinfo/fases-general)). 
-
-To send patches, please use `git-send-email`. A tutorial on how to use 
-it can be found [here](https://git-send-email.io/).
-
-## Donations
-
-Donations really help this project, no matter how small. People that work 
-on this project are unpaid volunteers that do it on their freetime.
-We currently only accept XMR/Monero. You can use these addresses for 
-donating.

-
-## Thank you!
-
-I would like to thank a few people there, mainly:
-
-- Andrew Yu, for making a mirror on their git server at git.andrewyu.org, and 
-linking the ##fases libera.chat channel to LibreIRC, for testing fases on
-OpenBSD and for hosting the mailing list.
-
-- Leah Rowe, for adding lots of improvements on her 
-[git repo](https://notabug.org/vimuser/fases) and for testing fases on OpenBSD.
-[Donate](https://www.patreon.com/libreleah).
-
-- Ron Nazarov, for fixing a weird bug in `yes` and adding useful features in 
-it.
-
-- Other people I forgot to add there. If I forgot to add you there, do send 
-a patch or just tell me :D.
-
-Contributions are very welcome, even if you're not a programmer. You can help 
-this project by:
-
-- Testing utilities and reporting bugs ;
-
-- Talking about fases ;
-
-- Donating XMR/Monero ;
-
-- Giving me recommendations.
+You can also run it with the `-i` argument to then install the package.
 
-Help is greatly appreciated, thanks!

-# fases - Ferass' Base System
-
-*Simple coreutils for a fully functionnal UNIX-like system*
-
-[« Go back](/README.md)
-
-## Coding Style
-
-The programming language used is ***POSIX C99*** and all code must be written 
-in ***POSIX C99***, no extensions are used.
-
-The coding style is as follows:
-
-### General
-
-- The code shall be as simple to understand as possible, add comments if 
-necessary ;
-
-- For indentation, the code shall use tab characters ;
-
-- The code shall avoid using GNU-specific functions (as that would make 
-the program less portable) ;
-
-- Each line shall not exceed 79 characters ;
-
-- Utilities shall only implement POSIX-compliant options, if the utility 
-supports options, and the specified option is invalid, the utility shall 
-print a help text (this applies only to coreutils) ;
-
-- Utilities shall only use the **standard C library and POSIX libraries** ;
-
-- For comments, instead of using `//` (as in `// Comment`), the code shall 
-use `/*` and `*/` (as in `/* Comment */`) ;
-
-- For commenting code, use `//` (as in `// printf("broken code")`) ;
-
-- **Variable names** shall describe the variable's purpose ;
-
-- The `main()` function shall be placed at the top, after function 
-prototypes, to increase code readability ;
-
-### Blocks
-
-- In a block, do not use `{` and `}` if there's only one instruction inside ;
-
-```
-for (int i; i != 3; i++)
-	printf("%d\n", i);
-```
-
-- When using `{` and `}`, `{` shall not be on it's own line ;
-
-```
-if (i) {
-	printf("%d", i);
-	i = 3;
-}
-```
-
-- The block shall only use 1 line if there's only one instruction ran and 
-that shall not exceed 79 characters ;
-
-```
-if (foo[1] == 'a') foo[1] = 'b';
-```
-
-### Functions
-
-- The function type shall be on the same line as the function name and `{` ;
-
-```
-int main() {
-	printf("Hello World.\n");
-}
-```
-
-- Function names shall describe the function's intended purpose ;
-
-- When exiting, the function shall use `return` instead of `exit()` ;
-	
-```
-int calculate(int i) {
-	int result;
-	if (i != 0)
-		result = 30 / 1;
-		return 0;
-	else
-		return 1;
-}
-```
-
-- Variable declarations shall be at the top of the function ;
-
-```
-int main() {
-	int i, result;
-	char foo;
-	bool bar;
-}
-```
-
-### Switch
-
-- In `switch (foo)`, `case` shall be indented ;
-
-```
-switch (foo) {
-	case 'b':
-		break;
-	case 'a':
-		printf("bar\n");
-	default:
-		return 0;
-}
-```
-
-### Preprocessor statements
-
-- The `#define` preprocessor statement shall only be used for setting 
-constant values ;
-
-```
-#define FOO 80
-```
-
-- Preprocessor statements shall not be indented.

-# fases - Ferass' Base System
-
-*Simple coreutils for a fully functionnal UNIX-like system*
-
-[« Go back](/README.md)
-
-## Compile
-
-You have 2 choices:
-
-- compile each utility separately;
-
-- compile only fasesiab which includes all utilities in a single binary.
-
-Modify the `config.mk` file to fit your needs in both cases.
-
-## Compiling each utility separately
-
-For example to compile `cat`, you have to run the following:
-
-	$ cd core/
-	$ make cat
-
-And to compile a non-POSIX utility such as `yes`, you have to run the 
-following:
-
-	$ cd extras/
-	$ make yes
-
-## Compiling fasesiab
-
-Fasesiab stands for Ferass' Base System in a box. It includes the entire 
-coreutils in a single and tiny binary.
-
-Before compiling, you have to prepare `fasesiab`.
-The `box.c` file should already contain some code but it may be outdated 
-so it's recommended to regenerate it:
-
-	$ make genbox
-
-Next, run the following:
-
-	$ make prepbox
-
-Now you're ready to compile! Run `make` and get a binary!
-
-	$ make box
-
-## Installation
-
-For now, you can only install fasesiab and no manpages are being installed. 
-To install, simply run the following:
-
-	$ doas make install
-
-Or, if using `sudo`:
-
-	$ sudo make install
-
-Then, you should have a binary called `box`. Make sure `/usr/local/bin/` or 
-whatever `DESTDIR` and `PREFIX` you set is in your `$PATH`.

-# fases - Ferass' Base System
-
-*Simple coreutils for a fully functionnal UNIX-like system*
-
-[« Go back](../README.md)
-
-## FAQ
-
-Here are questions someone could ask. Read it! It could answer some of your 
-questions.
-
-Q: Why another coreutils? There's already GNU, Busybox, OpenBSD's, and some more.
-
-A: Most coreutils are either non-POSIX or use non-portable functions not 
-specified by POSIX. The `fases` project separates POSIX and non-POSIX 
-utilities while others do not. Some have also quite complex code, making it 
-harder to study the code.
-
-[We're not trying to trash other coreutils. A lot of them 
-(Busybox, OpenBSD, ...) are actually really good]
-
-Q: Is fases going to work on <insert UNIX-like operating system name here>?
-
-A: Well, it depends on the system itself. If your system implements POSIX 
-functions in its libc, then it'll work. Utilities are currently tested on 
-- OpenBSD ;
-
-- FreeBSD ;
-
-- OS X/Mac OS X/MacOS (just a little) ;
-
-- Artix Linux and Arch Linux ;
-
-- Alpine Linux.
-
-No. `fases` will never work on Microsoft Windows.
-
----
-
-More coming soon.

-
-## Status
-
-The `fases` project is still incomplete as some utilities are missing, here's 
-what `fases` currently provides (most of those utilities are incomplete):
-
-- `ls`
-
-- `head`
-
-- `cat`
-
-- `yes`
-
-- `date`
-
-- `mkdir`
-
-- `echo`
-
-Other utilities are still in the making. Help is greatly appreciated.
-
-## Known bugs
-
-The `fases` project is still a Work-in-progress and as such, there are bugs.
-Please do report bugs to me, via IRC, email, or even by using Notabug.org 
-issues.
-
-| Bug                                          | Affected utility-ies |
-|-------------------------------------------------------------|-------|
-| Sometimes, `-l` would show incorrect permissions.           | `ls`  |
-| When there's a lot to print, `-l` fails with a memory error | `ls`  |
