Follow the instructions of generating the doc here.
Clone the docset repo.
Copy the contents of the concourse docs repo (after generating the doc) inside the
concourse-ci.docset/Contents/Resources/Documents folder of the docset repo
(including all html files, search_index.json and css, images, js folders).
Run the generateAll.sh script (which requires bash, tar, python).
As a result there will be created a concourse-ci.tgz in the root of the docset repo.
