+Exercises in Programming Style
 ==============================
 
 Comprehensive collection of well-known, and not so well-known, programming styles using a simple computational task, term frequency.
 
-Additions are welcome!
+Additions are welcome! 
+
+You can contribute: 
+- an example program that follows one of the existing styles, but written in a different programming language 
+- an entirely new programming style
+- new names for the existing styles
+- discussion of names, pros and cons of each style
+
+Please follow the conventions suggested by the existing code base
+specifically:
+
+- If you are contributing a program in a different programming language,
+add that file to the corresponding style folder and call it tf-nn.ext,
+where nn is the style number and ext is the language's standard
+extension suffix.
+
+- If you are contributing a new style, make a new folder called
+nn-funname and add an example program in that folder called
+tf-nn.ext. (nn is the next avalaible number in the collection)
+Additionally, add a README.md file that clearly describes the
+contraints for writing programs in that style. I will only consider
+new styles corresponding to constraints that are clearly different
+from the ones that already exist in the collection. (different
+programs written in existing styles are exercises for students, and
+should not be here)
+
+Contributions of new names and discussion should be done under Issues
+or on the Wiki part of this repo.
+
+Love,
+Crista
+
+P.S. Never stop exercising!
