Contribution Guidelines

Please, ensure your pull request adheres to the following guidelines.

Common sense

Search previous suggestions before making a new one, as yours may be a duplicate.
Make sure your section or item is useful before submitting. That implies it having enough content and every item a good succinct description.
Make an individual pull request for each suggestion.
The pull request and commit should have a useful title.

Check your spelling and grammar. Yeah, it includes capitalized titles. No, it doesn't include This Kind Of Capitalization.
Make sure your text editor is set to remove trailing whitespace.
When adding a item, section or subsection, do not forget to add an anchor link in the table of contents, matching the current list format.

Additions should be added to the bottom of the relevant category, and in the following format: - [Item name](link).

Note the - symbol. Your item must be included in a list, and a list is a section.

If your item doesn't fit any section or subsection already available, create one use the following format:

## Section Title

###### Subsection Title
- [Item name](link)

Thank you for your suggestions!
