+Using coala-quickstart to Generate a coala Configuration File
+=============================================================
+
+This document aims to make people aware of coala-quickstart by providing a
+brief introduction about its features and how to quickly generate
+coala configuration files for your projects.
+
+What is coala-quickstart?
+-------------------------
+
+coala-quickstart is a CLI tool that helps users to quickly get started with
+coala by generating a ``.coafile`` tailored for their project. The ``.coafile``
+is generated based on the questions answered by the users about their project.
+
+Features
+--------
+
+coala-quickstart offers the following features:
+
+- Out-of-the-box support for projects using various popular languages such as
+  C/C++, Python, JavaScript and many more with built-in check routines.
+- Automatic detection of languages used in your project.
+- Automatic identification of bears that might be relevant for your project and
+  detection of bear settings based on the languages used.
+- A clean and simple interface with a well defined flow.
+
+Installation
+------------
+
+To install the latest stable version run:
+
+::
+
+    $ pip3 install coala-quickstart
+
+To install the latest development version run:
+
+::
+
+    $ git clone https://github.com/coala/coala-quickstart.git
+    $ cd coala-quickstart
+    $ pip3 install .
+
+Usage
+-----
+
+To get started simply run:
+
+::
+
+    $ coala-quickstart
+
+This should prompt you for your project's directory. If you want to use your
+current directory, just press the return key.
+
+It will detect the languages used in your project and provide a percentage
+distribution of those languages in your project. You will now be presented
+with a list of bears that might be relevant to your project to choose from.
+Once you choose your bears you are done.
+
+At the end, you should have a file named ``.coafile`` generated at the root of
+your project directory. This contains all the settings needed by coala to lint
+and fix your code. You can also open the .coafile in your favorite editor and
+edit the settings to suit your needs.
+
+Once you have completed these steps just execute coala from your project's
+root:
+
+::
+
+    $ coala
