+# Development Guide
+
+This is a guide for developers who would like to contribute to this project.
+
+If you're interested in contributing to mycli, thank you. We'd love your help!
+You'll always get credit for your work.
+
+## GitHub Workflow
+
+1. [Fork the repository](https://github.com/dbcli/mycli) on GitHub.
+
+2. Clone your fork locally:
+    ```bash
+    $ git clone <url-for-your-fork>
+    ```
+
+3. Add the official repository (`upstream`) as a remote repository:
+    ```bash
+    $ git remote add upstream git@github.com:dbcli/mycli.git
+    ```
+
+4. Set up a [virtual environment](http://docs.python-guide.org/en/latest/dev/virtualenvs)
+   for development:
+
+    ```bash
+    $ cd mycli
+    $ pip install virtualenv
+    $ virtualenv mycli_dev
+    ```
+
+    We've just created a virtual environment that we'll use to install all the dependencies
+    and tools we need to work on mycli. Whenever you want to work on mycli, you
+    need to activate the virtual environment:
+
+    ```bash
+    $ source mycli_dev/bin/activate
+    ```
+
+    When you're done working, you can deactivate the virtual environment:
+
+    ```bash
+    $ deactivate
+    ```
+
+5. Install the dependencies and development tools:
+
+    ```bash
+    $ pip install -r requirements-dev.txt
+    $ pip install --editable .
+    ```
+
+6. Create a branch for your bugfix or feature based off the `master` branch:
+
+    ```bash
+    $ git checkout -b <name-of-bugfix-or-feature> master
+    ```
+
+7. While you work on your bugfix or feature, be sure to pull the latest changes from `upstream`. This ensures that your local codebase is up-to-date:
+
+    ```bash
+    $ git pull upstream master
+    ```
+
+8. When your work is ready for the mycli team to review it, push your branch to your fork:
+
+    ```bash
+    $ git push origin <name-of-bugfix-or-feature>
+    ```
+
+9. [Create a pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/)
+   on GitHub.
+
+
+## Running the Tests
+
+While you work on mycli, it's important to run the tests to make sure your code
+hasn't broken any existing functionality. To run the tests, just type in:
+
+```bash
+$ ./setup.py test
+```
+
+Mycli supports Python 2.7 and 3.4+. You can test against multiple versions of
+Python by running tox:
+
+```bash
+$ tox
+```
+
+
+### Test Database Credentials
+
+The tests require a database connection to work. You can tell the tests which
+credentials to use by setting the applicable environment variables:
+
+```bash
+$ export PYTEST_HOST=localhost
+$ export PYTEST_USER=user
+$ export PYTEST_PASSWORD=myclirocks
+$ export PYTEST_PORT=3306
+$ export PYTEST_CHARSET=utf8
+```
+
+The default values are `localhost`, `root`, no password, `3306`, and `utf8`.
+You only need to set the values that differ from the defaults.
+
+
+### CLI Tests
+
+Some CLI tests expect the program `ex` to be a symbolic link to `vim`.
+
+In some systems (e.g. Arch Linux) `ex` is a symbolic link to `vi`, which will
+change the output and therefore make some tests fail.
+
+You can check this by running:
+```bash
+$ readlink -f $(which ex)
+```
+
+
+## Coding Style
+
+Mycli requires code submissions to adhere to
+[PEP 8](https://www.python.org/dev/peps/pep-0008/).
+It's easy to check the style of your code, just run:
+
+```bash
+$ ./setup.py lint
+```
+
+If you see any PEP 8 style issues, you can automatically fix them by running:
+
+```bash
+$ ./setup.py lint --fix
+```
+
+Be sure to commit and push any PEP 8 fixes.

+Features
+--------
+
+`mycli` is written using [prompt_toolkit](https://github.com/jonathanslenders/python-prompt-toolkit/).
+
+* Auto-completion as you type for SQL keywords as well as tables, views and
+  columns in the database.
+* Syntax highlighting using Pygments.
+* Smart-completion (enabled by default) will suggest context-sensitive completion.
+    - `SELECT * FROM <tab>` will only show table names.
+    - `SELECT * FROM users WHERE <tab>` will only show column names.
+* Support for multiline queries.
+* Favorite queries with optional positional parameters. Save a query using
+  `\fs alias query` and execute it with `\f alias` whenever you need.
+* Timing of sql statments and table rendering.
+* Config file is automatically created at ``~/.myclirc`` at first launch.
+* Log every query and its results to a file (disabled by default).
+* Pretty prints tabular data (with colors!)
+* Support for SSL connections

+
+## Detailed Install Instructions:
+
+### Fedora
+
+Fedora has a package available for mycli, install it using dnf:
+
+```
+$ sudo dnf install mycli
+```
+
+### RHEL, Centos
+
+I haven't built an RPM package for mycli for RHEL or Centos yet. So please use `pip` to install `mycli`. You can install pip on your system using:
+
+```
+$ sudo yum install python-pip
+```
+
+Once that is installed, you can install mycli as follows:
+
+```
+$ sudo pip install mycli
+```
+
+### Windows
+
+Follow the instructions on this blogpost: https://www.codewall.co.uk/installing-using-mycli-on-windows/
+
+### Cygwin
+
+1. Make sure the following Cygwin packages are installed:
+`python3`, `python3-pip`.
+2. Install mycli: `pip3 install mycli`
+
+### Thanks:
+
+This project was funded through kickstarter. My thanks to the [backers](http://mycli.net/sponsors) who supported the project.
+
+A special thanks to [Jonathan Slenders](https://twitter.com/jonathan_s) for
+creating [Python Prompt Toolkit](http://github.com/jonathanslenders/python-prompt-toolkit),
+which is quite literally the backbone library, that made this app possible.
+Jonathan has also provided valuable feedback and support during the development
+of this app.
+
+[Click](http://click.pocoo.org/) is used for command line option parsing
+and printing error messages.
+
+Thanks to [PyMysql](https://github.com/PyMySQL/PyMySQL) for a pure python adapter to MySQL database.
+
+
+### Compatibility
+
+Mycli is tested on macOS and Linux.
+
+**Mycli is not tested on Windows**, but the libraries used in this app are Windows-compatible.
+This means it should work without any modifications. If you're unable to run it
+on Windows, please [file a bug](https://github.com/dbcli/mycli/issues/new).
+
+### Configuration and Usage
+
+For more information on using and configuring mycli, [check out our documentation](http://mycli.net/docs).
+
+Common topics include:
+- [Configuring mycli](http://mycli.net/config)
+- [Using/Disabling the pager](http://mycli.net/pager)
+- [Syntax colors](http://mycli.net/syntax)

+  ```
+

+
+  In the config file ~/.myclirc set `destructive_warning = False` which will

+1.3.0:
+======
+
+Features:
+---------
+* Add a new special command (\T) to change the table format on the fly. (Thanks: [Jonathan Bruno](https://github.com/brewneaux))
+  eg:
+  ```
+  mycli> \T tsv
+  ```
+* Add `--defaults-group-suffix` to the command line. This lets the user specify
+  a group to use in the my.cnf files. (Thanks: [Irina Truong](http://github.com/j-bennet))
+
+  In the my.cnf file a user can specify credentials for different databases and
+  invoke mycli with the group name to use the appropriate credentials.
+  eg:
+  ```
+  # my.cnf
+  [client]
+  user   = 'root'
+  socket = '/tmp/mysql.sock'
+  pager = 'less -RXSF'
+  database = 'account'
+
+  [clientamjith]
+  user     = 'amjith'
+  database  = 'user_management'
+
+  $ mycli --defaults-group-suffix=amjith   # uses the [clientamjith] section in my.cnf
+  ```
+
+* Add `--defaults-file` option to the command line. This allows specifying a
+  `my.cnf` to use at launch. This also makes it play nice with mysql sandbox.
+
+* Make `-p` and `--password` take the password in commandline. This makes mycli
+  a drop in replacement for mysql.
+
+1.2.0:
+======
+
+Features:
+---------
+
+* Add support for wider completion menus in the config file.
+
+  Add `wider_completion_menu = True` in the config file (~/.myclirc) to enable this feature.
+
+Bug Fixes:
+---------
+
+* Prevent Ctrl-C from quitting mycli while the pager is active.
+* Refresh auto-completions after the database is changed via a CONNECT command.
+

+* Honor the `pager` setting in my.cnf files. (Thanks: [Irina Truong](http://github.com/j-bennet))
+
+Bug Fixes:
+----------
+
+* Fix a crashing bug in completion engine for cross joins.
+* Make `<null>` value consistent between tabular and vertical output.
+
+Internal Changes:
