Welcome to the Raspberry Pi Documentation

This repository contains the Asciidoc source and the toolchain to build the Raspberry Pi Documentation. For details of how to contribute to the documentation see the CONTRIBUTING.md file.

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

This works on both regular Debian or 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.

You can install the necessary dependencies on Linux as follows,

$ sudo apt install -y ruby ruby-dev python3 python3-pip make ninja-build

then add these lines to the bottom of your $HOME/.bashrc,

export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"
export PATH="$PATH:$GEM_HOME/bin"

and close and relaunch your Terminal window to have these new variables activated. Finally, run

$ gem install bundler

to install the latest version of the Ruby bundle command.

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 [email protected]

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/[email protected]/lib
setenv CPPFLAGS -I/usr/local/opt/[email protected]/include
setenv PKG_CONFIG_PATH /usr/local/opt/[email protected]/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/[email protected]/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
Install Dependencies

Go ahead and brew install the other dependencies,

$ brew install [email protected]
$ brew install ninja

Install Scripting Dependencies

After you've installed the toolchain (on either Linux or macOS), you'll need to install the required Ruby gems and Python modules. Make sure you're in the documentation/ directory and then run,

$ bundle install

(which may take several minutes), followed by,

$ pip3 install --user -r requirements.txt

Building the Documentation Site

After you've installed both the toolchain and scripting dependencies, you can build the documentation with,

$ make

This will automatically use Ninja build to convert the source files in documentation/asciidoc/ to a suitable intermediate structure in build/jekyll/, and then use Jekyll AsciiDoc to convert the files in build/jekyll/ to the final output HTML files in documentation/html/.

You can also start a local server to view the built 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.

You can revert your repository to a pristine state by running,

$ make clean

which will delete the build/ and documentation/html/ directories.
