Working on the Docs

This page is about working with the DDEV documentation. See the Writing Style Guide for stylistic guidance.

Fix Docs Using Web Browser

The documentation is built and checked automatically with various GitHub Actions workflows. While it may help to check your work locally for more involved PRs, you can more quickly make suggestions using GitHub in a browser:

  1. Click the pencil in the upper right. That will take you to the right page on GitHub.
  2. Click the pencil button on GitHub and follow the instructions to create your change.
  3. Save your changes and follow the prompts to create a PR.
  4. In the checks on your PR, click the “details” link by docs/readthedocs.org:ddev to browse the docs build created by your PR.
  5. Once the PR has run its checks, you’ll see an item labeled docs/readthedocs.org:ddev. Click “Details” to review a docs build that includes your changes: Documentation preview build link
  6. Take a look at the “Check docs” action to make sure there were no linting or spelling errors.

Fork / Clone the DDEV Repository

To start making changes you’ll need a local copy of the DDEV documentation, so fork the DDEV repository which includes the documentation.

After forking the repository, you can clone it to your local machine.

Make Changes

Now that you’ve got a local copy, you can make your changes.

Action Path
Documentation ./docs/content/users/*
./docs/content/developers/*
MkDocs configuration ./mkdocs.yml
Front end ./docs/content/assets/extra.css
./docs/content/assets/extra.js

Preview Changes

Preview your changes locally by running make mkdocs-serve.

This will launch a web server on port 8000 and automatically refresh pages as they’re edited.

No need to install MkDocs locally!

It’s easiest to install MkDocs locally, but you don’t have to. The make mkdocs-serve command will look for and use a local binary, otherwise using make to build and serve the documentation. If you don’t have make installed on your system, you can directly run the command it would have instead:

TAG=$(arch)
if [ "${TAG}" = "arm64" ]; then TAG="${TAG}v8-1.5.2"; else TAG=1.5.2; fi
docker run -it -p 8000:8000 -v "${PWD}:/docs" -e "ADD_MODULES=mkdocs-material mkdocs-redirects mkdocs-minify-plugin mdx_truly_sane_lists mkdocs-git-revision-date-localized-plugin" -e "LIVE_RELOAD_SUPPORT=true" -e "FAST_MODE=true" -e "DOCS_DIRECTORY=./docs" "polinux/mkdocs:$TAG"

Installing mkdocs locally on macOS

On macOS with recent versions of Homebrew use this technique to install mkdocs:

brew install pipx
export PIPX_BIN_DIR=/usr/local/bin
pipx install mkdocs
pipx runpip mkdocs install -r docs/mkdocs-pip-requirements
pipx ensurepath

Check Markdown for Errors

Run make markdownlint before you publish changes to quickly check your files for errors or inconsistencies.

markdownlint-cli required!

The make markdownlint command requires you to have markdownlint-cli installed, which you can do by executing npm install -g markdownlint-cli

Check for Spelling Errors

Run make pyspelling to check for spelling errors. Output will be brief if all goes well:

➜  make pyspelling
pyspelling:
Spelling check passed :)

If you’ve added a correctly-spelled word that gets flagged, like “Symfony” for example, you’ll need to add it to .spellcheckwordlist.txt in the root of DDEV’s repository.

pyspelling and aspell required!

It’s probably best to install packages locally before attempting to run make pyspelling:

sudo -H pip3 install pyspelling pymdown-extensions
sudo apt-get install aspell

Publish Changes

If all looks good, it’s time to commit your changes and make a pull request back into the official DDEV repository.

When you make a pull request, several tasks and test actions will be run. One of those is a task named docs/readthedocs.org:ddev, which builds a version of the docs containing all the changes from your pull request. You can use that to confirm the final result is exactly what you’d expect.
