+Development Guide
+-----------------
+This is a guide for developers who would like to contribute to this project.
+
+GitHub Workflow
+---------------
+
+If you're interested in contributing to pgcli, first of all my heart felt
+thanks. `Fork the project <https://github.com/dbcli/pgspecial>`_ in github.
+Then clone your fork into your computer (``git clone <url-for-your-fork>``).
+Make the changes and create the commits in your local machine. Then push those
+changes to your fork. Then click on the pull request icon on github and create
+a new pull request. Add a description about the change and send it along. I
+promise to review the pull request in a reasonable window of time and get back
+to you.
+
+In order to keep your fork up to date with any changes from mainline, add a new
+git remote to your local copy called 'upstream' and point it to the main
+``pgspecial`` repo.
+
+::
+
+ $ git remote add upstream git@github.com:dbcli/pgspecial.git
+
+Once the 'upstream' end point is added you can then periodically do a ``git
+pull upstream master`` to update your local copy and then do a ``git push
+origin master`` to keep your own fork up to date.
+
+Local Setup
+-----------
+
+The installation instructions in the README file are intended for users of
+``pgspecial``. If you're developing ``pgspecial``, you'll need to install it in
+a slightly different way so you can see the effects of your changes right away
+without having to go through the install cycle every time you change the code.
+
+It is highly recommended to use virtualenv for development. If you don't know
+what a virtualenv is, this `guide
+<http://docs.python-guide.org/en/latest/dev/virtualenvs/#virtual-environments>`_
+will help you get started.
+
+Create a virtualenv (let's call it ``pgspecial-dev``). Activate it:
+
+::
+
+ virtualenv ./pgspecial-dev
+ source ./pgspecial-dev/bin/activate
+
+Once the virtualenv is activated, `cd` into the local clone of pgspecial folder
+and install pgspecial using pip as follows:
+
+::
+
+ $ pip install --editable .
+
+ or
+
+ $ pip install -e .
+
+This will install the necessary dependencies as well as install pgspecial from
+the working folder into the virtualenv. By installing it using `pip install -e`
+we've linked the pgspecial installation with the working copy. So any changes
+made to the code is immediately available in the installed version of
+pgspecial.
+
+Adding PostgreSQL Special (Meta) Commands
+-----------------------------------------
+
+If you want to add a new meta-command, you'll write a function that accepts 3
+parameters. Then you'll mark it with a ``@special_command`` decorator. For
+an example, look at ``list_roles`` in ``dbcommands.py``:
+
+ ::
+
+ @special_command('\\du', '\\du[+] [pattern]', 'List roles.')
+ def list_roles(cur, pattern, verbose):
+ # some code here
+ return [(None, cur, headers, cur.statusmessage)]
+
+Things to note:
+
+* Your function should return 4 items: ``title, cur, headers, status``.
+* ``title`` is optional. It is something you can print out as first line of your
+ output.
+* ``cur`` is cursor that contains records to iterate.
+* ``headers`` is result table's list of column headers.
+* ``status`` is optional. If provided, it will be printed out last.
+
+Now, take a closer look at the decorator. The first item in a tuple of
+arguments is the command's name. It should be unique. The second item is this
+command's syntax. The third item in the tuple is a string which is
+the documentation for that special command.
+
+The example command here, ``\du``, is a meta-command that lists all roles in
+the databases. The way you can see the SQL statement issued by PostgreSQL when
+this command is executed is to launch `psql -E` and entering ``\du``.
+
+That will print the results and also print the sql statement that was executed
+to produce that result. In most cases it's a single sql statement, but
+sometimes it's a series of sql statements that feed the results to each other
+to get to the final result.
+
+Running the tests
+-----------------
+
+The tests are using default user ``postgres`` at ``localhost``, without
+the password (authentication mode ``trust``). This can be changed in
+``tests/db_utils.py``.
+
+First, install the requirements for testing:
+
+::
+
+ $ pip install -r requirements-dev.txt
+
+After that, tests can be run with:
+
+::
+
+ $ py.test
+
+Pytest configuration can be found in the ``tool.pytest.ini_options`` table of the ``pyproject.toml`` file.
+
+Enforcing the code style (linting)
+------------------------------
+
+When you submit a PR, the changeset is checked for pep8 compliance using
+`black <https://github.com/psf/black>`_. If you see a build failing because
+of these checks, install ``black`` and apply style fixes:
+
+::
+
+ $ pip install black
+ $ black .
+
+Then commit and push the fixes.
+
+To enforce ``black`` applied on every commit, we also suggest installing ``pre-commit`` and
+using the ``pre-commit`` hooks available in this repo:
+
+::
+
+ $ pip install pre-commit
+ $ pre-commit install
+
+Git blame
+---------
+
+Use ``git blame my_file.py --ignore-revs-file .git-blame-ignore-revs`` to exclude irrelevant commits
+(specifically Black) from ``git blame``. For more information,
+see `here <https://github.com/psf/black#migrating-your-code-style-without-ruining-git-blame>`_.

+Meta-commands for Postgres
+--------------------------
+
+|Build Status| |PyPI|
+
+This package provides an API to execute meta-commands (AKA "special", or
+"backslash commands") on PostgreSQL.
+
+Quick Start
+-----------
+
+This is a python package. It can be installed with:
+
+::
+
+ $ pip install pgspecial
+
+
+Usage
+-----
+
+Once this library is included into your project, you will most likely use the
+following imports:
+
+.. code-block:: python
+
+ from pgspecial.main import PGSpecial
+ from pgspecial.namedqueries import NamedQueries
+
+Then you will create and use an instance of PGSpecial:
+
+.. code-block:: python
+
+ pgspecial = PGSpecial()
+ for result in pgspecial.execute(cur, sql):
+ # Do something
+
+If you want to import named queries from an existing config file, it is
+convenient to initialize and keep around the class variable in
+``NamedQueries``:
+
+.. code-block:: python
+
+ from configobj import ConfigObj
+
+ NamedQueries.instance = NamedQueries.from_config(
+ ConfigObj('~/.config_file_name'))
+
+Contributions:
+--------------
+
+If you're interested in contributing to this project, first of all I would like
+to extend my heartfelt gratitude. I've written a small doc to describe how to
+get this running in a development setup.
+
+https://github.com/dbcli/pgspecial/blob/master/DEVELOP.rst
+
+Please feel free to file an issue if you need help.
+
+Projects using it:
+------------------
+
+This library is used by the following projects:
+
+pgcli_: A REPL for Postgres.
+
+`ipython-sql`_: %%sql magic for IPython
+
+OmniDB_: An web tool for database management
+
+If you find this module useful and include it in your project, I'll be happy
+to know about it and list it here.

+Meta-commands for Postgres
+--------------------------
+
+|Build Status| |PyPI|
+
+This package provides an API to execute meta-commands (AKA "special", or
+"backslash commands") on PostgreSQL.
+
+Quick Start
+-----------
+
+This is a python package. It can be installed with:
+
+::
+
+ $ pip install pgspecial
+
+
+Usage
+-----
+
+Once this library is included into your project, you will most likely use the
+following imports:
+
+.. code-block:: python
+
+ from pgspecial.main import PGSpecial
+ from pgspecial.namedqueries import NamedQueries
+
+Then you will create and use an instance of PGSpecial:
+
+.. code-block:: python
+
+ pgspecial = PGSpecial()
+ for result in pgspecial.execute(cur, sql):
+ # Do something
+
+If you want to import named queries from an existing config file, it is
+convenient to initialize and keep around the class variable in
+``NamedQueries``:
+
+.. code-block:: python
+
+ from configobj import ConfigObj
+
+ NamedQueries.instance = NamedQueries.from_config(
+ ConfigObj('~/.config_file_name'))
+
+Contributions:
+--------------
+
+If you're interested in contributing to this project, first of all I would like
+to extend my heartfelt gratitude. I've written a small doc to describe how to
+get this running in a development setup.
+
+https://github.com/dbcli/pgspecial/blob/master/DEVELOP.rst
+
+Please feel free to file an issue if you need help.
+
+Projects using it:
+------------------
+
+This library is used by the following projects:
+
+pgcli_: A REPL for Postgres.
+
+`ipython-sql`_: %%sql magic for IPython
+
+OmniDB_: An web tool for database management
+
+If you find this module useful and include it in your project, I'll be happy
+to know about it and list it here.
