 Minimal Development Install for Ubuntu and other Linux distributions
 ====================================================================
 
+***THIS IS A WORK IN PROGRESS***
 
-This is tested on a minimal Ubuntu 22.04 docker image (`docker pull ubuntu:22.04; docker run -it ubuntu:22.04`) as of 2022-09-27 by Alan De Smet.
 
-For non-Ubuntu systems, you'll need to adjust package installation to your system.
+You will need:
 
-You need git (to get glance) and python's venv module (to at least isolate glance's install, but also any other modules you need that aren't available from the system).
+- git
+- python3
+- python3's venv support
 
-As root:
+On Debian or Ubuntu, this might do the job if you have sudo access:
 
 ```
-apt update
-apt install -y git python3-venv
+sudo apt install git python3 python3-venv
 ```
 
-**Optional**: To allow glance to use system-wide module installations, do this. This takes about 933 MiB on a _minimal_ Ubuntu install.
+For other distributions you'll need to adjust package installation to your system.
 
-As root:
+**Optionally**, you can install other dependencies system-wide. On Debian/Ubuntu this looks like:
 
 ```
-DEBIAN_FRONTEND=noninteractive apt-get install -y python3-numpy python3-matplotlib python3-mako python3-mock python3-scipy python3-pillow python3-cartopy python3-pil python3-netcdf4 python3-h5py libgeos-dev
+sudo DEBIAN_FRONTEND=noninteractive apt-get install -y build-essential python3-numpy python3-matplotlib python3-mako python3-mock python3-scipy python3-pil python3-cartopy python3-pil python3-netcdf4 python3-h5py libgeos-dev python3-venv python3.10-venv python3-setuptools-whl python3-pip-whl
 ```
 
+If you don't do so, the `pip` command later will handle installing from PyPI.
 
-**Optional**: This provide a system-wind module isntall for the GUI components. It takes about 430 MiB on a _minimal_ Ubuntu install.
+**Optionally**, if you want the GUI, you'll need QT5 installed. If you're on Debian or Ubuntu, this might work:
 
-As root:
+```
+sudo DEBIAN_FRONTEND=noninteractive apt-get install -y libqt5gui5
+```
+
+**Optionally**, you can install the pyqt5 dependencies system-wide as well:
 
 ```
-apt install -y python3-pyqt5 
+sudo DEBIAN_FRONTEND=noninteractive apt-get install -y python3-pyqt5
 ```
 
+
+
+
 **If** you didn't install the system-wide packages, you'll need basic build tools to install some modules (at least cartopy). In that case, you'll need this. It's about 100 MiB on a _minimal_ Ubuntu install.
