-How to release pytest
---------------------------------------------
+Release Procedure
+-----------------
+
+Our current policy for releasing is to aim for a bugfix every few weeks and a minor release every 2-3 months. The idea
+is to get fixes and new features out instead of trying to cram a ton of features into a release and by consequence
+taking a lot of time to make a new one.

+=================
+Development Guide
+=================
+
+Some general guidelines regarding development in pytest for core maintainers and general contributors. Nothing here
+is set in stone and can't be changed, feel free to suggest improvements or changes in the workflow.
+
+
+Code Style
+----------
+
+* `PEP-8 <https://www.python.org/dev/peps/pep-0008>`_
+* `flake8 <https://pypi.python.org/pypi/flake8>`_ for quality checks
+* `invoke <http://www.pyinvoke.org/>`_ to automate development tasks
+
+
+Branches
+--------
+
+We have two long term branches:
+
+* ``master``: contains the code for the next bugfix release.
+* ``features``: contains the code with new features for the next minor release.
+
+The official repository usually does not contain topic branches, developers and contributors should create topic
+branches in their own forks.
+
+Exceptions can be made for cases where more than one contributor is working on the same
+topic or where it makes sense to use some automatic capability of the main repository, such as automatic docs from
+`readthedocs <readthedocs.org>`_ for a branch dealing with documentation refactoring.
+
+Issues
+------
+
+Any question, feature, bug or proposal is welcome as an issue. Users are encouraged to use them whenever they need.
+
+GitHub issues should use labels to categorize them. Labels should be created sporadically, to fill a niche; we should
+avoid creating labels just for the sake of creating them.
+
+Here is a list of labels and a brief description mentioning their intent.
+
+
+**Type**
+
+* ``type: backward compatibility``: issue that will cause problems with old pytest versions.
+* ``type: bug``: problem that needs to be addressed.
+* ``type: deprecation``: feature that will be deprecated in the future.
+* ``type: docs``: documentation missing or needing clarification.
+* ``type: enhancement``: new feature or API change, should be merged into ``features``.
+* ``type: feature-branch``: new feature or API change, should be merged into ``features``.
+* ``type: infrastructure``: improvement to development/releases/CI structure.
+* ``type: performance``: performance or memory problem/improvement.
+* ``type: proposal``: proposal for a new feature, often to gather opinions or design the API around the new feature.
+* ``type: question``: question regarding usage, installation, internals or how to test something.
+* ``type: refactoring``: internal improvements to the code.
+* ``type: regression``: indicates a problem that was introduced in a release which was working previously.
+
+**Status**
+
+* ``status: critical``: grave problem or usability issue that affects lots of users.
+* ``status: easy``: easy issue that is friendly to new contributors.
+* ``status: help wanted``: core developers need help from experts on this topic.
+* ``status: needs information``: reporter needs to provide more information; can be closed after 2 or more weeks of inactivity.
+
+**Topic**
+
+* ``topic: collection``
+* ``topic: fixtures``
+* ``topic: parametrize``
+* ``topic: reporting``
+* ``topic: selection``
+* ``topic: tracebacks``
+
+**Plugin (internal or external)**
+
+* ``plugin: cache``
+* ``plugin: capture``
+* ``plugin: doctests``
+* ``plugin: junitxml``
+* ``plugin: monkeypatch``
+* ``plugin: nose``
+* ``plugin: pastebin``
+* ``plugin: pytester``
+* ``plugin: tmpdir``
+* ``plugin: unittest``
+* ``plugin: warnings``
+* ``plugin: xdist``
+
+
+**OS**
+
+Issues specific to a single operating system. Do not use as a means to indicate where an issue originated from, only
+for problems that happen **only** in that system.
+
+* ``os: linux``
+* ``os: mac``
+* ``os: windows``
+
+**Temporary**
+
+Used to classify issues for limited time, to help find issues related in events for example.
+They should be removed after they are no longer relevant.
