@halyssonJr first things first, remove the build folder. I'll check why the .gitignore is still considering the _build folder when adding the files.

[pedrominatel]

@halyssonJr please be aware of not adding the unrelated folders and files of your build and environment to the commit. Add only the files that you are working on.

Can you clarify why you've changed the docs/source/conf.py file?

[halyssonJr]

@pedrominatel, maybe i just have uncommented, but not made any changes directly to the docs/source/conf.py file

[pedrominatel]

PTAL at my considerations.

[halyssonJr]

@pedrominatelI, I try to split my commit. So I can't upload just the files I changed. In the next PR I will fix these problems

[pedrominatel]

@halyssonJr your PR is messed. You suppose to edit only one file but now you have added 191!

If you need help to understand the Git flow I'll be glad to help. Currently, your PR is not following the expectations and cant be reviewed. Ping me later if you need help.

@halyssonJr please take a look at my modifications.

New version available.

Overall looks good. Found only one small typo.
