+- Make an individual pull request for each suggestion.
+- Use the following format: `[name](link) - Description.`
+- Additions should be added to the bottom of the relevant category.
+- Link to the startup plan page, not the company's website.
+- Keep descriptions short and simple, but descriptive.
+- Start the description with a capital and end with a full stop/period.
+- Check your spelling and grammar.
+- Make sure your text editor is set to remove trailing whitespace.
+- The pull request should have a useful title and include a link to the startup plan and why it should be included.
+- New categories or improvements to the existing categorization are welcome, but should be done in a separate pull request.

+Thank you for your suggestion!

+### Updating your PR
+
+A lot of times, making a PR adhere to the standards above can be difficult. If the maintainers notice anything that we'd like changed, we'll ask you to edit your PR before we merge it. If you're not sure how to do that, [here is a guide](https://github.com/RichardLitt/knowledge/blob/master/github/amending-a-commit-guide.md) on the different ways you can update your PR so that we can merge it.
