Certbot Website

Website for EFF's Certbot project. Uses Jekyll for static site generation.

Build Status


Building with GitHub Actions

If you're developing directly on this repository rather than on a fork, it's probably easiest to let GitHub Actions build the site for you.

All branches and pull requests are built and tested by GitHub Actions.

For branches, the built assets are pushed to an analagous branch in certbot/website-builds. Built assets from PRs are not saved because GitHub Actions doesn't provide a mechanism to securely push to a Github repo after PRs across forks.

To view the build of any branch, use the script, which will fetch the branch from certbot/website-builds and start a docker to serve the files.


After starting that command, you can access the website in your browser at http://localhost:8000. To shut the server down, just hit Ctrl+C in the terminal where is running.

If you are on linux and your user is not a member of the docker group, you'll need to run the command with sudo.

Building locally with Docker

  1. Clone this repo and cd into the project directory.
  2. Get the documentation submodule:
  • git submodule init
  • git submodule update
  1. docker-compose up

docker-compose serves the site with nginx to more closely mirror production. Any changes you make to your local files while the site is running will automatically be picked up and you can access the website in your browser at http://localhost:4000.

Building locally without Docker


  1. Install ruby 2.0+, node 8.0+, and npm 2.0+.
  2. gem install jekyll (requires v3.0 or higher)
  3. sudo npm install gulp-cli -g
  4. npm install

If you want to build a copy of the documentation for your local mirror of the Cerbot website, also do:

  1. git submodule init
  2. git submodule update
  3. ./ depend
  4. Install pdflatex e.g. via sudo apt install texlive texlive-latex-extra


To watch for changes and reload assets as needed via BrowserSync: gulp watch

To build the site once: gulp build

To build for production (minified javascript, no source maps): gulp build --env production The environment can also be set in the NODE_ENV environment variable. See

Editing content

Basic pages

Most pages can be edited as markdown files.

Use /index.html to edit the homepage. Use /[RELATIVE_URL]/index.html to edit internal pages.

Hosting providers list

  • Make sure to fill out the name, link, category, and reviewed fields.
  • reviewed should be a date in format 2019.7.11.
  • link is usually a link to the provider's main page; it's where clicking on the name will go.
  • for category, see descriptions here.
  • for full/partial categories, one of the links provided should have evidence of being in that category.
  • only one of tutorial, announcement, plan will show up, in that order.
  • partial should have tutorial.
  • full providers shouldn't need a tutorial to turn on https. an exception might include instructions of what to do if something goes wrong and the automatic https doesn't work.
  • if one provider offers multiple products, either split into two entries or note it in the note field.
  • the note field is good for things like noting which products have https, or that the site is available only in certain languages. it's not meant for advertising.
  • all unused fields should be ""

Installation instructions

Are generated by JavaScript with Mustache, and can be edited in _scripts/instruction-widget.


FAQ entries are a Jekyll collection. Add FAQ entries (question and answer pairs) as markdown files to the _faq_entries directory.

FAQ entries require two variables to be set in the front matter:

  • title: the "Question" the FAQ entry answers
  • weight: the position of this entry on the page - lighter FAQ entries will float to the top.


Certbot/website uses html-proofer to validate the html output of the build.

To install:

gem install html-proofer

To run the tests:

npm test

(Files with known issues are ignored.)
