+## CadQuery Module for FreeCAD
+

+- [Installation](installation.md)

+
+### Introduction
+This project adds a workbench to FreeCAD that makes it easy to get started using the [CadQuery API](http://dcowden.github.io/cadquery/).
+
+![User Interface](cqfm_user_interface.png)
+
+There are two philosophies that are probably the most influential in the design of this project.
+
+1. _"Batteries Included"_ - A user should not have to install a lot of requirements to get started.
+2. _Flexibility_ - A user should be able to customize this workbench for their workflow. Being able to use an external code editor is an example.
+
+A stock code editor is included, along with examples showing everything from basic to advanced CadQuery scripting. This workbench also includes [cqparts](https://github.com/fragmuffin/cqparts), which is a library that adds support for parts and assemblies with constraints on top of CadQuery.
+
+Customizable settings are available, including settings that allow the use of an external code editor, if desired.

+
+This process can be repeated to update the module every time changes are pushed to the master branch on GitHub.
+
+### Manual
+Sometimes a different version or branch of the workbench may be needed, other than what is installed using the addon manager. The steps below outline
+1. Download the [latest released version](https://github.com/jmwright/cadquery-freecad-module/releases)
+2. Extract the archive file
+3. Copy the entire extracted directory to FreeCAD's `Mod` directory on your system. Typical `Mod` directory locations are listed below.
+
+**Linux Mod Locations**
+- /usr/lib/freecad/Mod
+- /usr/local/lib/freecad/Mod
+- ~/.FreeCAD/Mod
+
+**Windows Mod Locations**
+- C:\Program Files\FreeCAD 0.14\Mod
+- C:\Program Files (x86)\FreeCAD 0.14\Mod
+- C:\Users\[your_user_name]\Application Data\FreeCAD\Mod
+
+**Mac Mod Locations**
+- /Applications/FreeCAD.app/Contents/Mod
+- /Applications/FreeCAD.app/Mod
+- /Users/[your_user_name]/Library/Preferences/FreeCAD/Mod
+- ~/Library/Preferences/FreeCAD/Mod
+
+### Troubleshooting
+If you are running Ubuntu Linux, you may need to run the following line in a terminal before using this module.
+```
+sudo apt-get install python-pyside.qtnetwork
+```
+
+### Next Steps
+Once the workbench is installed, the next step is to read through the [usage instructions](usage.md).
