Description

Description

The link in word here points to an anchor that does not exist in file:

### Pull Request guidelines

- Don't create a pull request on an issue that doesn't exist, create an issue first and if the changes you are proposing are said to be okay, you can go ahead and create a pull request
- Don't work on the main branch, create your own branch by following the instructions [here](#-how-to-make-a-pull-request)

Maybe it should point here: #### 👌🏾 How to fill a pull request template(Text) ?
