How to compile API documentation of specified tag of ember-data?

Hi I am using ember-data tagged v.1.13.4 and I would like to use its API documentation. There is always the newest version available at Ember - 4.6 - Ember API Documentation but it sometimes make things darker. I found this project - but alas I don’t know how to use is (the very fast is to fast for me - there are steps I don’t get). Is it possible to keep local ember api documentation regarding specified version (tag)? How to do it? Thanks!
