To propose a lesson, please consult our call for lessons. Before submitting a proposal, consult as well our author guidelines and look over our published lessons and our publishing pipeline.

After your lesson has been accepted into our review process, your assigned editor will work with you to upload your lesson to this ph-submissions repository.

For more information, see our author guidelines and editor guidelines. Our translation guidelines are currently being updated.

We publish all our lessons in Markdown. Lessons should be titled: "lesson-name". The lesson markdown file will be uploaded to the corresponding language folder (for example, "en"), and placed either in the drafts/originals directory or the drafts/translations directory. Sample lessons, with proper yaml header, can be viewed in these directories.

Image files should be named: "lesson-image-1", "lesson-image-2". Image files go in the images directory, inside a folder named with the same slug as your lesson.
