| # Before we go on, two things to note: | |
| # First, on web scraping: | |
| # You should always check the terms of the site you are extracting data from, to make sure scraping (often referred to as `crawling`) is not prohibited. One way to do this is to visit the website’s `robots.txt` page, and ensure that a) there is nothing explicitly stating that crawlers are not permitted, and b) ideally, the site simply states that all user agents are permitted (indicated by a line saying `User-Agect: *`). Both of those are the case for our use-case today (see https://www.ultimatetennisstatistics.com/robots.txt). | |
| # And second, about those custom fonts: |
This is about how to split a GitHub pull request, following a real in-the-wild example.
So it happened that I once wanted to fix a bug (#832) on the shelljs repository.
I forked the repository, cloned it and created a new branch called ln-directory-dest. I fixed the bug, created a pull request, and implemented initial review feedback.
At this point, I had added the commits A, B, C, D, E and [F](https://github.com/Loilo/shelljs/commit/946ab48bf5cf9c8aac03407
