 ### Release Packages
 
-Stable release builds which do not require Anaconda are attached to the [latest release](https://github.com/CadQuery/CQ-editor/releases). Download the zip file for your operating system, extract it, and run the CQ-editor script for your OS (CQ-editor.cmd for Windows, CQ-editor.sh for Linux and MacOS). On Windows you should be able to simply double-click on CQ-editor.cmd. On Linux and MacOS you may need to make the script executable with `chmod +x CQ-editor.sh` and run the script from the command line. The script contains an environment variable export that may be required to get CQ-editor to launch correctly on MacOS Big Sur, so it is better to use the script than to launch CQ-editor directly.
+TBD
 
 ### Development Packages
 
-Development builds are also available, but can be unstable and should be used at your own risk. Click on the newest build with a green checkmark [here](https://github.com/jmwright/CQ-editor/actions?query=workflow%3Abuild), wait for the _Artifacts_ section at the bottom of the page to load, and then click on the appropriate download for your operating system. Extract the archive file and run the shell (Linux/MacOS) or cmd (Windows) script in the root CQ-editor directory. The CQ-editor window should launch.

-## Installation (Anaconda)
+## Installation (pip)
 
-Use conda to install:
 ```
-conda install -c cadquery -c conda-forge cq-editor=master
-```
-and then simply type `cq-editor` to run it. This installs the latest version built directly from the HEAD of this repository.
-
-Alternatively clone this git repository and set up the following conda environment:
-```
-conda env create -f cqgui_env.yml -n cqgui
-conda activate cqgui
-python run.py
-```
-
-On some linux distributions (e.g. `Ubuntu 18.04`) it might be necessary to install additonal packages:
-```
-sudo apt install libglu1-mesa libgl1-mesa-dri mesa-common-dev libglu1-mesa-dev
-```
-On Fedora 29 the packages can be installed as follows:
-```
-dnf install -y mesa-libGLU mesa-libGL mesa-libGLU-devel
+pip install git+https://github.com/jdegenstein/jmwright-CQ-Editor
+pip install --pre git+https://github.com/cadquery/cadquery
 ```
