# Best practises for contribute developing

I'm interested in contribute documenting the algorithms and properties of Cadabra.

As a first step, I forked the repository. Then, I created a new branch called documentation, and start the conversion of a couple of algorithms.

I've tried to create a pull request for the changes... but it seems to be a problem with something called Travis CI!

Questions

• Which branch should I create the request to? feature/python3 or master?

• Is it a (real) problem the Travis CI build ?

• Do you have any suggestions for the best practises of development?

Cheers.
