+# The Linux Kernel Module Programming Guide
+
+This project keeps the Linux Kernel Module Programming Guide up to date, with [working examples](examples/) for recent 5.x kernel versions.
+The guide has been around since 2001 and most copies of it on the web only describe old 2.6.x kernels.
+
+The book can be freely accessed via https://sysprog21.github.io/lkmpg/ or [latest PDF file](https://github.com/sysprog21/lkmpg/releases).
+The original guide may be found at [Linux Documentation Project](http://www.tldp.org/LDP/lkmpg/).
+You may check other [freely available programming books](https://ebookfoundation.github.io/free-programming-books-search/) listed by The [Free Ebook Foundation](https://ebookfoundation.org/) or [Linux online books](https://onlinebooks.library.upenn.edu/webbin/book/browse?type=lcsubc&key=Linux) collected by [The Online Books Page](https://onlinebooks.library.upenn.edu/).
+
+## Getting Started
+
+### Summary
+1. Get the latest source code from the [GitHub page](https://github.com/sysprog21/lkmpg).
+2. Install the prerequisites.
+3. Generate PDF and/or HTML documents.
+
+### Step 1: Get the latest source code
+
+Make sure you can run `git` with an Internet connection.
+
+```shell
+$ git clone https://github.com/sysprog21/lkmpg.git && cd lkmpg
+```
+
+### Step 2: Install the prerequisites
+
+To generate the book from source, [TeXLive](https://www.tug.org/texlive/) ([MacTeX](https://www.tug.org/mactex/)) is required.
+
+For Ubuntu Linux, macOS, and other Unix-like systems, run the following command(s):
+
+```bash
+# Debian / Ubuntu
+$ sudo apt install make texlive-full
+
+# Arch / Manjaro
+$ sudo pacman -S make texlive-binextra texlive-bin
+
+# macOS
+$ brew install mactex
+$ sudo tlmgr update --self
+```
+
+Note that `latexmk` is required to generated PDF, and it probably has been installed on your OS already. If not, please follow the [installation guide](https://mg.readthedocs.io/latexmk.html#installation).
+
+In macOS systems, package `Pygments` may not be pre-installed. If not, please refer to the [installation guide](https://pygments.org/download/) before generate documents.
+
+Alternatively, using [Docker](https://docs.docker.com/) is recommended, as it guarantees the same dependencies with our GitHub Actions workflow.
+After install [docker engine](https://docs.docker.com/engine/install/) on your machine, pull the docker image [twtug/lkmpg](https://hub.docker.com/r/twtug/lkmpg) and run in isolated containers.
+
+```shell
+# pull docker image and run it as container
+$ docker pull twtug/lkmpg
+$ docker run --rm -it -v $(pwd):/workdir twtug/lkmpg
+```
+
+[nerdctl](https://github.com/containerd/nerdctl) is a Docker-compatible command line tool for [containerd](https://containerd.io/), and you can replace the above `docker` commands with `nerdctl` counterparts.
+
+### Step 3: Generate PDF and/or HTML documents
+
+Now we could build document with following commands:
+
+```bash
+$ make all              # Generate PDF document
+$ make html             # Convert TeX to HTML
+$ make clean            # Delete generated files
+```
