As @proudofsimin had requested to list down the changes in the updated timeline for easier understanding, there are as follows:

• We have added a section called Installation page to our overall tutorial structure, and added it under our week 2 tasks.
• Instead of keeping the "Usage with Docker" and "Usage with Heroku" under Tutorials, it is to be included under How-to guides (only links for those pages will be under tutorials so that users can quickly navigate to them if they are searching for it, this resolves the conflict between the tutorials and the how-to guide sections).
• Remaining things are almost the same, just diluted the timeline to 17 weeks, @proudofsimin you can update them on your docs (where you are tracking the completion of tasks w.r.t. PRs).

We have also kept our Team proposal docs updated with these changes, and if any further changes are required we will update it in this Docs.
