 ## Status / Future
 This is now a bit of a monster of many minds and yet continues to bear fruit.  I plan to continue to use this code to try new geometries and features to share.  I am still working on a new generator, but feel this one can continue to evolve and inform the other effort.
 
-## Generating a Design
+## Installation
+
+There are three different environments in which you can run this application. Depending on which you choose, the installation process will vary.
+
+- [Docker Environment](#docker-environment-installation)
+- [Conda Environment](#conda-environment-installation)
+- [Python Environment](#python-environment-installation)
+
+### Docker Environment Installation
+
+Running the application with Docker is the most convenient way to do so. In addition to a straightforward installation, this also allows you to generate models in the background without having to keep a shell open.
+
+*Note:* If you are using Windows, see [Docker Autobuild](#docker-autobuild).
+
+Before you proceed, ensure you have installed [Docker](https://www.docker.com/) and the `docker` command is available from your terminal.
+
+There are two tools you can use to help manage the Docker containers associated with this project. 
+
+#### Make
+
+If you prefer, you can use `make` to manage the containers. Type `make help` to see the available commands.
+
+#### Bash Script
+
+The `dactyl.sh` bash script provides a CLI to manage the containers. Type `./dactyl.sh --help` to see all CLI options.
+
+In addition to the CLI you can run `./dactyl.sh` without any arguments to use an interactive menu. 
+
+Upon running the script, you will be prompted to build the dactyl-keyboard Docker image.
+
+Once the image is built, you can choose which containers to run on an as-needed basis. In general, you can start, stop, rebuild, inspect, and remove the containers via the CLI/Menu. 
+
+You can also remove all of the Docker artifacts by running the included uninstaller.
+
+*Tip:* Run `./dactyl.sh shell --session` to jump into a bash session inside of the shell container.
+
+### Conda Environment Installation
+
+After the Docker installation, Anaconda is the next best option. Before you begin, ensure you have installed [Anaconda](https://docs.anaconda.com/anaconda/install/index.html) and the `conda` command is available from your terminal.
+
+You can install all of the dependencies by hand, but you can automate the install by running the bash script `./conda.sh`. This will create a python 3.7 environment named `dactyl-keyboard` and install all of the required dependencies.
+
+If you would like to install into a conda environment manually, check the bash script to see all of the required commands.
+
+If you would like to remove the conda artifacts, run `./conda.sh --uninstall`.
+
+### Python Environment Installation
+
+You can install the application in a regular python environment, but it is not recommended. You will not be able to take advantage of the updated geometry generated by the CadQuery engine, as this is only available via the Docker/Anaconda installation.
 
 **Setting up the Python environment - NEW**
 * [Install Python 3.X](https://www.python.org/downloads/release/python-385/) or use your [favorite distro / platform (Anaconda)](https://www.anaconda.com/products/individual) 
 * It is advisable, but not necessary, to setup a virtual environment to prevent package/library incompatibility 
 * [Install Numpy](https://pypi.org/project/numpy/), easiest method is `pip install numpy` or `pip3 install numpy` on linux.
