 ## Background
 Yet another rewrite of my [personal site](https://ayo.ayco.io)

-1. Install Flask and dependencies. The following are the steps for MacOS/Linux:
+## Set up -- needs Linux
+1. Install dependencies
     1. create python environment: `python3 -m venv .venv`
     2. activate python env: `. .venv/bin/activate`
     3. install wheel: `pip install wheel`
     4. install gunicorn & flask: `pip install gunicorn flask`
 2. To start development:
-    1. Set environment variable for the flask app entry point with `export FLASK_APP=api.py`
-    2. run the development server: `flask run`; note that the default port (5000) needs to be open
+    1. allow port usage: `sudo ufw allow 5000`
+    2. run the development server: `python api.py``
 3. After development session, deactivate the python env with: `deactivate`
