+# Contribution Guidelines
+Please ensure your pull request adheres to the following guidelines:
+
+* Listings in the [README](README.md) should be for SugarCE only. 
+* Please search previous suggestions before making a new one, as yours may be a duplicate.
+* Please make an individual commit for each listing in a pull request.
+* Put a link to each library in your pull request ticket, so they're easier to look at.
+* There should be no code, e.g. zip files, in the pull request (or the repository itself). This is information and listing purposes only. 
+* Use the following format for libraries: \[LIBRARY\]\(LINK\) - DESCRIPTION.
+* New categories, or improvements to the existing categorization are welcome.
+* All listings within a category should be alphabetical. 
+* Keep descriptions short and simple. 
+* End all descriptions with a full stop/period.
+* Check your spelling and grammar.
+* Make sure your text editor is set to remove trailing whitespace.
+
+Thank you!
