Android Kernel Compilation Guide

This gist is intended to assist beginners, like myself, in getting started with Android Kernel Compilation. Please note that while I'm sharing my setup and process, this guide may not be entirely accurate, and I welcome suggestions from experienced developers to improve it.

Installing Build Tools

I am on Arch, so I will be using pacman to install the base-devel package group.

sudo pacman -S base-devel

On a Debian based distro, you can use apt and install the build-essential package.

Read Shape Up by basecamp on a kindle / reMarkable / eReader

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.

There is a .pdf version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.

Part 1: Convert to a single page

NOTE: This has only been tested on Chrome
