+Guidelines for Contributors
+===========================
+
+Contributions to the project are welcome. Please feel free to submit pull requests
+using the standard `GitHub flow <https://guides.github.com/introduction/flow/>`_.
+
+
+Version Control
+^^^^^^^^^^^^^^^
+
+The CFELPyUtils library is developed using the `Git <https://git-scm.com>`_ version
+control system.
+
+It uses the branching strategy proposed by Vincent Driessen and commonly known as
+`Gitflow <https://nvie.com/posts/a-successful-git-branching-model>`_.
+
+
+Python
+^^^^^^
+
+The CFELPyUtils library is mainly developed in `Python  <https://www.python.org>`_.
+
+* All code in the library must run with both version 2 and 3 of Python, except for
+  facility-specific code that specifically requires one of the two versions (for
+  example, Python 2 for the LCSL facility). The code must specifically support all the
+  currently active versions of python:
+
+  * Python 2
+
+    * 2.7
+
+  * Python 3
+
+    * 3.5
+    * 3.6
+    * 3.7
+
+* The `python-future <https://python-future.org>`_ project should be used to ensure
+  that code contributed to the project is compatible with all the supported versions of
+  Python.
+
+* The Python coding style should follow for the most part the `Google Python \
+  Coding Style <https://github.com/google/styleguide/blob/gh-pages/pyguide.md>`_.
+
+* All docstrings should be written following the `Google Style \
+  <https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html>`_.
+
+* `Pylint <https://www.pylint.org>`_ should be run on the code before
+  submission, as stated in the Google Python Coding Style Guide. In the root
+  folder of the CFELPyUtils repository, contributors can find  a 'pylintrc' file with
+  the settings that should be applied when linting the code. Please see `here
+  <http://pylint.pycqa.org/en/latest/user_guide/run.html?highlight=pylintrc>`_ how to
+  use the pylintrc file.
+  
+* The `Black <https://github.com/psf/black>`_ Python code formatter should be run on
+  the code before submission.
+
+
+C/C++
+^^^^^
+
+Some extension can, for performance reason, be written using the `C++
+<https://en.wikipedia.org/wiki/C%2B%2B>`_ or  `C
+<https://en.wikipedia.org/wiki/C_(programming_language)>`_ programming languages.
+
+* All C++ code in OnDA must follow at most the C++98 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* Part of the C++11 standard can be used when writing extensions. However, it must be
+  possible to compile the code using version 4.8 of the 'gcc' compiler (in order to
+  create the Linux binary Python wheel).
+
+* All C code in OnDA must follow at most the C99 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* The `Cython <http://cython.org>`_ project should be used to interface C/C++ code with
+  Python.

+Contributions to the project are welcome. Please feel free to submit pull requests

+
+
+Version Control
+^^^^^^^^^^^^^^^
+
+The CFELPyUtils library is developed using the `Git <https://git-scm.com>`_ version
+control system.
+
+It uses the branching strategy proposed by Vincent Driessen and commonly known as
+`Gitflow <https://nvie.com/posts/a-successful-git-branching-model>`_.
+
+
+Python
+^^^^^^
+
+The CFELPyUtils library is mainly developed in `Python  <https://www.python.org>`_.
+
+* All code in the library must run with both version 2 and 3 of Python, except for
+  facility-specific code that specifically requires one of the two versions (for
+  example, Python 2 for the LCSL facility). The code must specifically support all the
+  currently active versions of python:
+
+  * Python 2
+
+    * 2.7
+
+  * Python 3
+
+    * 3.5
+    * 3.6
+    * 3.7
+
+* The `python-future <https://python-future.org>`_ project should be used to ensure
+  that code contributed to the project is compatible with all the supported versions of
+  Python.
+
+* The Python coding style should follow for the most part the `Google Python \
+  Coding Style <https://github.com/google/styleguide/blob/gh-pages/pyguide.md>`_.
+
+* All docstrings should be written following the `Google Style \
+  <https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html>`_.
+
+* `Pylint <https://www.pylint.org>`_ should be run on the code before
+  submission, as stated in the Google Python Coding Style Guide. In the root
+  folder of the CFELPyUtils repository, contributors can find  a 'pylintrc' file with
+  the settings that should be applied when linting the code. Please see `here
+  <http://pylint.pycqa.org/en/latest/user_guide/run.html?highlight=pylintrc>`_ how to
+  use the pylintrc file.
+  
+* The `Black <https://github.com/psf/black>`_ Python code formatter should be run on
+  the code before submission.
+
+
+C/C++
+^^^^^
+
+Some extension can, for performance reason, be written using the `C++
+<https://en.wikipedia.org/wiki/C%2B%2B>`_ or  `C
+<https://en.wikipedia.org/wiki/C_(programming_language)>`_ programming languages.
+
+* All C++ code in OnDA must follow at most the C++98 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* Part of the C++11 standard can be used when writing extensions. However, it must be
+  possible to compile the code using version 4.8 of the 'gcc' compiler (in order to
+  create the Linux binary Python wheel).
+
+* All C code in OnDA must follow at most the C99 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* The `Cython <http://cython.org>`_ project should be used to interface C/C++ code with
+  Python.

+Guidelines for Contributors
+===========================
+
+Contributions to the project are welcome. Please feel free to submit pull requests
+using the standard `GitHub flow <https://guides.github.com/introduction/flow/>`_.
+
+
+Version Control
+^^^^^^^^^^^^^^^
+
+The CFELPyUtils library is developed using the `Git <https://git-scm.com>`_ version
+control system.
+
+It uses the branching strategy proposed by Vincent Driessen and commonly known as
+`Gitflow <https://nvie.com/posts/a-successful-git-branching-model>`_.
+
+
+Python
+^^^^^^
+
+The CFELPyUtils library is mainly developed in `Python  <https://www.python.org>`_.
+
+* All code in the library must run with both version 2 and 3 of Python, except for
+  facility-specific code that specifically requires one of the two versions (for
+  example, Python 2 for the LCSL facility). The code must specifically support all the
+  currently active versions of python:
+
+  * Python 2
+
+    * 2.7
+
+  * Python 3
+
+    * 3.5
+    * 3.6
+    * 3.7
+
+* The `python-future <https://python-future.org>`_ project should be used to ensure
+  that code contributed to the project is compatible with all the supported versions of
+  Python.
+
+* The Python coding style should follow for the most part the `Google Python \
+  Coding Style <https://github.com/google/styleguide/blob/gh-pages/pyguide.md>`_.
+
+* All docstrings should be written following the `Google Style \
+  <https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html>`_.
+
+* `Pylint <https://www.pylint.org>`_ should be run on the code before
+  submission, as stated in the Google Python Coding Style Guide. In the root
+  folder of the CFELPyUtils repository, contributors can find  a 'pylintrc' file with
+  the settings that should be applied when linting the code. Please see `here
+  <http://pylint.pycqa.org/en/latest/user_guide/run.html?highlight=pylintrc>`_ how to
+  use the pylintrc file.
+  
+* The `Black <https://github.com/psf/black>`_ Python code formatter should be run on
+  the code before submission.
+
+
+C/C++
+^^^^^
+
+Some extension can, for performance reason, be written using the `C++
+<https://en.wikipedia.org/wiki/C%2B%2B>`_ or  `C
+<https://en.wikipedia.org/wiki/C_(programming_language)>`_ programming languages.
+
+* All C++ code in OnDA must follow at most the C++98 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* Part of the C++11 standard can be used when writing extensions. However, it must be
+  possible to compile the code using version 4.8 of the 'gcc' compiler (in order to
+  create the Linux binary Python wheel).
+
+* All C code in OnDA must follow at most the C99 ISO standard, and the code
+  must compile on a Linux RHEL7/CentOS7 platform using the standard development stack
+  that comes with these systems.
+
+* The `Cython <http://cython.org>`_ project should be used to interface C/C++ code with
+  Python.
