We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Mejorar la guía de CONTRIBUTING
Tenemos una pequeña guía que explica el procedimiento. Sin embargo, estaría bueno mejorarla un poco para que sea más fácil de seguir para persona que no sepan mucho de github y demás herramientas: https://github.com/raulcd/python-docs-es/blob/3.7/CONTRIBUTING.rst

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
--- BEGIN FILES ---
Path: `conf.py`
Content:
```
1 # Sphinx configuration file.
2 #
3 #  - import original configurations from cpython/Doc/conf.py
4 #  - append the path considering the cpython submodule is at ./cpython
5 #  - create the symbolic links under ./cpython/locale/es/LC_MESSAGES
6 #  - make the build to work under Read the Docs
7 #
8 # The git submodule was created using this Stack Overflow answer
9 # to fetch only the commit that I needed and avoid clonning the whole history
10 # https://stackoverflow.com/a/27445058
11 #
12 # This can be built locally using `sphinx-build` by running

14 #   $ sphinx-build -b html -n -d _build/doctrees -D language=es . _build/html
