+
+File descriptors are numbers that represent files.
+They are mostly used in file related syscalls.
+
+# `FILE_DESCRIPTOR_ARRAY_CHUNK_SIZE` - macro
+The amount of file descriptors a `file_descriptor_array_chunk_T` (reference needed) can hold.
+
+# `file_descriptor_t` - typedef
+This is a typedef of `ìnt32_t` and represents a file descriptor.
+
+# `std_file_descriptors_E` - enum
+These are reserved file descriptors.
+* `FILE_DESCRIPTOR_INVALID` - This represents an invalid file descriptor, just like NULL is an invalid pointer.
+
+# `file_descriptor_array_chunk_T` - struct
+| Name   | Type                                           | Description                                                                            |

+| next   | file_descriptor_array_chunk_T*                 | The next chunk                                                                         |
+| lookup | vfs_node_T* [FILE_DESCRIPTOR_ARRAY_CHUNK_SIZE] | The array of file pointers, that the file descriptors reference                        |
+| bitmap | bitmap_T                                       | This bitmap indicates which file descriptors of this chunk are free nad which are used |
+| amount | uint32_t                                       | The amount of file descriptors which the chunk actually holds                          |

+| base_chunk | file_descriptor_array_chunk_T* | The first chunk in the array |
+
+# `file_descriptor_request(fd_array, node)` - function (file_descriptor_t)
+Requests and returns new file descriptor, which will be linked with _**node**_.
+
+# `file_descriptor_resolve(fd_array, fd)` - function (vfs_node_T*)
+Returns the VFS node, with which _**fd**_ is linked.
+
+# `file_descriptor_free(fd_array, fd)` - function (void)
+Frees _**fd**_ and marks it as reclaimable.
+
+# `file_descriptor_array_alloc()` - function (file_descriptor_array_T*)
+Allocates a new chunked file descriptor array.
+
+# `file_descriptor_array_destruct(fd_array)` - function (void)
+Destructs _**fd_array**_ and all its resources, like e.g. chunks.
+
+# `file_descriptor_array_chunk_alloc(prev)` - function (file_descriptor_array_chunk_T*)
+Allocates a new chunk for a file descriptor array.
+_**prev**_ has to be the last chunk of an array or NULL when the chunk is the base chunk for a fresh file descriptor array.
+
+# `file_descriptor_array_chunk_destruct(chunk)` - function (void)
+Destructs _**chunk**_ and all its resources.

+title: "Code Style"
+summary: "Read this, before contributing!"
+---
+
+The following code style should be applied to the whole noxos codebase.
+Pull Requests that don't follow this code style will be rejected.
+
+# 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. meaningfully names.
+The times of 80-char 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 (definitely written 100% sober):
+```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`
