New content and complex changes

To add new chapters, write longer snippets of text or add images, you first need to fetch a copy of the documentation on your local computer.

Either use the GitHub app for your operating system (mentioned above) or git command line to get the repository locally. The repository address is located on your own GitHub repository fork front page:

git clone

Then, create a branch for your new changes to sit in. Naming the branch in relation to the changes you will make can help.

git checkout -b contributing

Download the GitBook Editor application to your computer.

Then you can open the documentation in GitBook Editor (File > Open book).

Make any changes in the documentation using GitBook and then save changes (Book > Save all).

If you don't want to download the GitBook Editor app you can also go to the GitBook website, sign up for free with your GitHub account, then work directly in your browser.

Making a pull request

After you are done editing, you have to create a pull request on GitHub. PoppyGirls will get notified about the pull request, review your changes, suggest any corrections if needed and then pull your changes to the master version.

In your own repository on GitHub press do Compare & pull request


Fill in the information why this change is being made. The reviewer can see the details of the actual change, so you don't need repeat the content of the change.

Then press Create pull request.

GitHub emails will notify you for the follow up process.

Building the documentation (advanced users)

If you want to build the HTML version on your computer, without installing the desktop application of the GitBook Editor, you can also build the book with a command line tool.

You have to install npm and calibre (the way depends on your OS).

git clone
cd poppy-docs/

npm install gitbook-cli -g
gitbook install
gitbook build ./
gitbook pdf ./
