+# Build instructions
+**DISCLAIMER: To build this project you need a linux system (WSL could work for windows users, but I haven't tested it)**
+
+
+First you need to clone the repository:
+
+`git clone https://codeberg.org/antifallobst/noxos/`
+
+then there are a few tools required, that need to be installed:
+* **gcc** - compiler
+* **ld** - linker
+* **nasm** - assembler
+* **cmake** - build system
+* **xorriso** - ISO creation tools
+* **qemu** - emulator
+
+There is a shell script to setup the workspace and compile.
+Just run it using the following commands:
+```bash
+cd noxos
+./build.sh
+```
+If the Bootloader (Limine ([github](https://github.com/limine-bootloader/limine))) isn't downloaded yet, the script will download it.
+
+The final ISO file will be written to the *build* directory.
+
+To launch the ISO, run the `run.sh` script.
+
+# UEFI Emulation
+To emulate an UEFI system, you need to install the `ovmf` package.
+Then you can do `./run.sh uefi` to start qemu with uefi instead of bios.
+
+# Debugging
+## Logs
+When running through the script, qemu is configured to write the kernels logs to *STDOUT* and a file called *noxos.log*.
+## GDB
+You can connect GDB to qemu.
+To achieve this, run `./run.sh debug`.
+QEMU will wait until you connect GDB to it as a 'remote' target on `localhost:1234`.
+```bash
+gdb build/cmake/kernel/kernel
+target remote localhost:1234
+c
+```
+(note, that the last to commands have to be 'executed' in gdb not in your shell)

+# Code Style
+## Naming conventions
+- **structs** are suffixed with **_T**
+- **typedefs** are suffixed with **_t**
+- **enums** are suffixed with **_E**
+- **global**  variables are prefixed with **g_**
+
+Everything is **snake_case**.
+
+## Code readability
+To make the code as readable and self explaining as possible, there are a few patterns that should be used.
+
+### Avoid abbreviations
+Give your variables, functions, etc. meaningfull names.
+The times of 80char wide screens are over, feel free to use that space :D
+
+Example: `sym_at_idx` -> `get_symbol_at_index`
+
+But you're not forced to (anything) write out everything.
+For example the **Interrupt Descriptor Table** is simply referred to as **idt** (this abbreviation is btw standard).
+
+### Avoid indentation nesting
+In a perfect codebase, the maximum indention level would be 3.
+The goal of NoxOS is not to be a perfect codebase, but please avoid huge indention nesting.
+To achieve this, you can break parts into extra functions and/or use the early return pattern.
+
+Example:
+```c
+bool likes_pigs (void* a) {
+    if (a != NULL) {
+        if (a == 0xACAB) {
+            return false;
+        }
+    }
+    return true;
+}
+```
+->
+```c
+bool likes_pigs (void* a) {
+    if (a != NULL)   { return true; }
+    if (a != 0xACAB) { return true; }
+    
+    return false;
+}
+```
+
+### align declarations
+
+Please align declarations, definitions, etc like in the example:
+```c
+char      am_i_a_variable  = '?';
+uint64_t  number           = 0;
+bool      i_waste_bits     = true;
+```
+
+### namespaces
+Unlike C++ C has no namespaces.
+To achieve the goal of namespaces, please prefix your functions, structs, etc. with the "namespace" they are in.
+
+Example: `out_byte` -> `io_out_byte`

+Welcome :D
+
+Nice, that you're interested in contributing.
+
+There are several ways to contribute to NoxOS:
+- Write code
+- Maintain Documentation
+    - Typos
+    - Grammar
+    - Is the documentation up to date?
+- Plan stuff (e.g. syscalls)
+- open Issues
+
+# Before Contribution
+Please read the [Code-Style wiki entry](https://codeberg.org/antifallobst/noxos/wiki/Code-Style) before you start to contribute.
+
+For workspace setup and build instructions look at [this wiki entry](https://codeberg.org/antifallobst/noxos/wiki/Build-instructions).
+
+**We don't accept any Assholes! If you're a fascist, racist, or discriminate others for anything, go fuck yourself.**
+
+# Contributing
+
+When you contribute code, please [document](https://codeberg.org/antifallobst/noxos/wiki/Kernel-documentation) it.
+You don't have to (and you also shouldn't) write romans, but a few lines for every in a header exposed function, struct etc. help others (and yourself) understanding how to interact with your code.
+
+
+## What dafuq is ...?
+OS development can be quite complicated/confusing. That's Ok.
+Stuff like Paging can be really weird, if you don't have osdev experience.
+But there are learning resources and places, where you can ask questions.
+
+**A small overview about such resources and places:**
+- The [osdev wiki](https://wiki.osdev.org) is like wikipedia - just for hobby os developers.
+- The [osdev subreddit](https://reddit.com/r/osdev) is a great place to ask questions and share knowledge
+- Intel's [developer manual](https://www.intel.com/content/www/us/en/developer/articles/technical/intel-sdm.html) is a more advanced but kinda precise information source
+
+Also feel free to join the [NoxOS Matrix space](https://matrix.to/#/#noxos:systemausfall.org),
+where you can chat with other NoxOS devs and ask questions.
+**But Stay Respectful, Or We `sudo rm -rf /` Your PC ;)** 
+
+# Where to start?
+
+Get the codebase and play a bit around with it.
+Try to understand basic concepts of the codebase, the [documentation](https://codeberg.org/antifallobst/noxos/wiki/Kernel-documentation) will help you.
+After that you can search the [Issues](https://codeberg.org/antifallobst/noxos/issues) for the `Good First Issue` label,
+to find easy improvements, etc. that you can try to implement.
+Another option is to ask in the [Matrix Space](https://matrix.to/#/#noxos:systemausfall.org).

 NoxOS is a small x86 operating system (currently just a kernel).
 The kernel is booted using the limine boot protocol and is fully documented.
