[brownsarahm]

• adds community badge procedures from kwl template file
• fixes a typo to lower experience badge requirement and clarify lab requirement in additional examples
• clarifies title on some pages to make information easier to find

@AymanBx Can you confirm this answers your question?

@brownsarahm looks good, but if I may make a couple of suggestions to make it look less vague.

Possibly on lines (305-306) in badges.md it can say:

• In the community_contributions.md file on your kwl repo, add an item in a bulleted list (start the line with - )
• Include a link to your contribution like [text to display](url/of/contribution)

And in grading.md it can say:

You will maintain a list of your contributions in your KWL repo in the community_contributions.md file. Every individual change to this file (representing one contribution) should be commited to a new branch and then submitted as a PR, with a review requested from @brownsarahm.

Could you put those in as suggestions using the PR review features to add inline comments? This lets you practice with PR review features and is worth a second community badge.

Sorry, I don't know why I didn't think of that!

You can make this a suggestion using the add a suggestion button ()

(using that feature is the second badge worthy actitivy)
