To make changes edit the source files in the source/docs folder.
You can add a new file to the source/docs folder (or an appropriate sub-folder) to create a new page.
It is probably easiest to copy an existing file and change the name if you are new to writing text in markdown.
To submit changes to this repo, raise a PR in the usual way detailing documentation changes in the description.
The Digital Handbook was built using the gds-way as a starting point.
To preview or build the website, we need to use the terminal.
You can use the Dockerfile provided:
docker build . -t digital-handbook
docker run --rm -p 4567:4567 -p 35729:35729 -v $(pwd):/usr/src/docs -it digital-handbook
Alternatively, you can simply run the startup.sh script, which automates the above steps:
./startup.sh
Otherwise, the following steps will get Middleman running locally.
Install Ruby with Rubygems, preferably with a Ruby version manager, and the Bundler gem.
A .ruby-version file is provided for use with rbenv. If you update it, please update the Dockerfile.
Clone the repository using:
git clone https://github.com/cabinetoffice/digital-handbook
cd digital-handbook
If you are using a Mac with Apple silicon (such as an M1 chip), you must run additional commands.
Note If you are using an Intel Mac, skip this and go to the ‘Install the required gems’ step.
Tell Bundler to use libraries relating to the Apple silicon architecture:
bundle lock --add-platform arm64-darwin-21
bundle config --local specific_platform true
bundle config --local build.ffi --enable-libffi-alloc
We need to make sure the EventMachine gem is built with OpenSSL from Homebrew and not the default macOS version of OpenSSL.
First, install OpenSSL 1.1:
brew install openssl@1.1
Do not worry if Homebrew says OpenSSL 1.1 is already installed.
Then tell your Mac to use the Homebrew installation of OpenSSL 1.1 when looking for packages (this will last until you end your terminal session):
export PKG_CONFIG_PATH=$(brew --prefix openssl@1.1)/lib/pkgconfig
Then in the application folder type the following to install the required gems:
bundle config set path 'vendor/bundle'
bundle install
Whilst writing documentation we can run a middleman server to preview how the published version will look in the browser. After saving a change the preview in the browser will automatically refresh.
The preview is only available on our own computer. Others will not be able to access it if they are given the link.
Type the following to start the server:
bundle exec middleman server
If all goes well something like the following output will be displayed:
== The Middleman is loading
== LiveReload accepting connections from ws://192.168.0.8:35729
== View your site at "http://Laptop.local:4567", "http://192.168.0.8:4567"
== Inspect your site configuration at "http://Laptop.local:4567/__middleman", "http://192.168.0.8:4567/__middleman"
You should now be able to view a live preview at http://localhost:4567.
If you want to publish the website without using a build script you may need to build the static HTML files.
Type the following to build the HTML:
bundle exec middleman build
This will create a build subfolder in the application folder which contains
the HTML and asset files ready to be published.
If you want to verify that all of the external links in every page work (i.e.
do not return an HTTP error code), use the check_links.rb script.
bundle exec ruby check_links.rb
This script is automatically run as part of CI, but skipped on the main branch (so that the main branch can always be deployed).
This repo is continuously deployed from the main branch by GitHub Actions, using the workflow defined in /.github/workflows/deploy-to-pages.yaml.
