+* python >=3.8
 * numpy
 * scipy
 
 
 Install from PyPI with pip:

 ### Development install
-Install python3.7, virtualenv, and git:
+Install python3 and git:
 ```bash
 # This is for Debian/Ubuntu/other-apt-based systems; you may need an alternative command
-sudo apt install python3.7 virtualenv build-essential python3.7-dev git
-```
-
-If python 3.7 is not your default python3 version, create a virtualenv:
-```bash
-# Check python3 version:
-python3 --version
-# output on my system: Python 3.7.5rc1
-# If this indicates a version >= 3.7, you can skip all
-#  the steps involving virtualenv or referencing the venv/ directory
-
-# Create a virtual environment using python3.7 and place it in the directory `venv/`
-virtualenv -p python3.7 venv
+sudo apt install python3 build-essential python3-dev git
 ```
 
 In-place development install:
 ```bash
 # Download using git
-#git clone https://mpxd.net/code/jan/meanas.git
+git clone https://mpxd.net/code/jan/meanas.git
+
+# If you'd like to create a virtualenv, do so:
+python3 -m venv my_venv
 
 # If you are using a virtualenv, activate it
-source venv/bin/activate
+source my_venv/bin/activate
 
-# Install in-place (-e, editable) from ./meanas, including testing and example dependencies ([test, examples])
