 ## Making a SasView Development Environment
 
-### Develop using `venv`
+### Prerequisite: Obtaining the source code
 
-If you're familiar with working with developing in Python, then the very quick version is:
+Obtain the SasView source using `git`. This step is the same whether you are using `venv` or Pixi to create the development environment. You will likely need to coordinate
+updates to `sasdata` and `sasmodels`. The
+[`bumps`](https://github.com/bumps/bumps) and
+[`periodictable`](https://github.com/python-periodictable/periodictable)
+packages are far more loosely coupled, but depending on what you are
+doing you may also want them as development packages.
 
 ```shell
 # clone the repository
 git clone https://github.com/sasview/sasdata/
 git clone https://github.com/sasview/sasmodels/
 git clone https://github.com/sasview/sasview/

+### Develop using `venv`

+```shell
 cd sasview
 
-# create the virtual environment
+# Create the virtual environment
 python -m venv .venv
 # .venv\Scripts\activate & REM Windows: activate environment
 . .venv/bin/activate  # Linux/Mac: activate environment
 
-# install repositories in editable/developer mode in the venv
-# use "python -m ..." to ensure the venv's pip is used
+# Install repositories in editable/developer mode in the venv
+# Use "python -m ..." to ensure the venv's pip is used
 python -m pip install -e ../sasdata
 python -m pip install -e ../sasmodels
 python -m pip install -e .[dev,test]
 
-# test if sasview launches
+# Test if sasview launches
 python -m sas

 1.  Create a Python virtual environment in the `.venv` directory.
 1.  Activate the `.venv` so that Python and its modules from the venv are used.
     Note that the particular syntax above works for the `bash` and `zsh` shells under Linux, Windows and macOS;
