# Documentation Style Guide

These are the guidelines for writing documentation.

## Titles

* Each page must have a single `#`-level title at the top.
* Chapters in the same page must have `##`-level titles.
* Sub-chapters need to increase the number of `#` in the title according to

  their nesting depth.
* All words in the page's title must be capitalized, except for conjunctions

  like "of" and "and" .
* Only the first word of a chapter title must be capitalized.

```
# Arrays

## Print Width

To be easy to read when editing the markdown code, if the sentence is too long, divide it down. The recommended column length limit is 80.

## Code Output

To create output from code, there are two rules:

* If the output is short then put it as a comment
* If the output is quite long (column) then write it in a separate section after the code section.

## Indentation

Indentation must use spaces and the tab size must be 4.
