Getting started with Linux kernel development

Prerequisites

The Linux kernel is written in C, so you should have at least a basic understanding of C before diving into kernel work. You don't need expert level C knowledge, since you can always pick some things up underway, but it certainly helps to know the language and to have written some userspace C programs already.

It will also help to be a Linux user. If you have never used Linux before, it's probably a good idea to download a distro and get comfortable with it before you start doing kernel work.

Lastly, knowing git is not actually required, but can really help you (since you can dig through changelogs and search for information you'll need). At a minimum you should probably be able to clone the git repository to a local directory.

技術文書の書き方

このメモは、私（@ymmt2005）が長年にわたってソフトウェアプロダクト開発に関わってきて 2022年現在こうしたほうが良いと考えているベストプラクティスです。

科学的な分析等に基づくわけではない経験則であるため、今後も随時見直すことがありますし、ここに書いてあることが常に正しいわけでもあらゆるソフトウェア開発に適するわけでもありません。

しかしながら、実務経験が豊富で、モダンな技術スタックに明るいエンジニアの経験則は一定の役に立つのではないかと考えて記します。

	* Due to a limitation in the Figma /styles endpoint, we need to use a
