HI @neelimagoogly , Thanks for the PR !
Its a good practice to use Github Keywords in issues/ PR https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/using-keywords-in-issues-and-pull-requests . For example for This PR
It could be

• Resolve Create User Manual and Tutorial #132

Here , this resolve keyword with issue which is resolved / contributed by PR will be closed automatically when PR is reviewed and merged !
And also one suggestion on branching and commit messages ( I also personally need to work on commit msgs though haha )
We use [commitizen](https://commitizen-tools.github.io/commitizen/) , It would be easy and good on long run if you have proper naming for your branch and commit . In long term People may forget and try to checkout the work done or even for the developer itself it would be hard to track and manage branches if it is patch 1 patch 2 if you name it differently then will be easy to follow , for eg : for this PR it could be docs/tutorial

@kshitijrajsharma @omranlm I know this PR has been merged, can we now link the content to this page https://fair-dev.hotosm.org/documentation ? I can then also build an FAQ and link to documentation and we can even add some of the videos/tutorials there.
