Welcome to the Raspberry Pi Documentation

This repository contains the Asciidoc source and the toolchain to build the Raspberry Pi Documentation.

NOTE: This repository has undergone some recent changes. See our blog post for more details.

Building the Documentation

Instructions on how to checkout the documentation repo, and then install the toolchain needed to convert from Asciidoc to HTML and build the documentation site.

Checking out the Repository

Install git if you don't already have it, and check out the documentation repo as follows,

$ git clone https://github.com/raspberrypi/documentation.git
$ cd documentation

Installing the Toolchain

On Linux

You can install the necessary dependencies on Linux as follows,

$ sudo apt-get -qq -y install ruby ruby-bundler ruby-dev build-essential python3 git ninja-build

This works on both regular Ubuntu Linux — and has been tested in a minimal Docker container — and also under Raspberry Pi OS if you are working from a Raspberry Pi.

On macOS

If you don't already have it installed you should go ahead and install HomeBrew,

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Then you need to install Ruby,

$ brew install ruby@2.7

NOTE: Homebrew defaults to Ruby 3.0 which is incompatible with Asciidoctor.

Set up Homebrew Version of Ruby

If you're using csh or tcsh add the following lines to your .cshrc or .tcshrc,

setenv PATH /usr/local/opt/ruby/bin:${PATH}
setenv PATH ${PATH}:/usr/local/lib/ruby/gems/2.7.0/bin
setenv LDFLAGS -L/usr/local/opt/ruby@2.7/lib
setenv CPPFLAGS -I/usr/local/opt/ruby@2.7/include
setenv PKG_CONFIG_PATH /usr/local/opt/ruby@2.7/lib/pkgconfig

or if you're using bash add the following lines to your .bash_profile,

export PATH="/usr/local/opt/ruby/bin:$PATH"
export PATH="$PATH:/usr/local/lib/ruby/gems/2.7.0/bin"
export PATH="/usr/local/opt/ruby@2.7/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/ruby@2.7/lib"
export CPPFLAGS="-I/usr/local/opt/ruby@2.7/include"
export PKG_CONFIG_PATH="/usr/local/opt/ruby@2.7/lib/pkgconfig"

Install Dependencies

Go ahead and brew install the other dependencies,

$ brew install python@3
$ brew install ninja

Configuring the Repository

After you've installed the toolchain, you'll need to install the required Ruby gems. Make sure you're in the documentation directory and then run,

$ bundle install

Building the Documentation Site

After you've installed the toolchain and configured the repository you can build the documentation with,

$ make

This will automatically convert the build/jekyll/ files to HTML and put them into documentation/html/.

You can also start a local server to view the compiled site by running,

$ make serve_html

As the local server launches, the local URL will be printed in the terminal -- open this URL in a browser to see the locally-built site.

To build without an active internet connection, run

$ OFFLINE_MODE=1 make

which will copy the fonts.html and header.html files from offline_includes (instead of downloading them from esi.raspberrypi.org).
