-Authentication happens via pyOIDC with CSH SSO, authenticating as the user who is viewing the page.
-We have two different realms, and the site changes depending which realm is in use.

-The server uses heavy caching via lru_cache to speed up the results as much as possible

-Setup
-------
-
-For local development setup follow these steps:
+## Usage
+To run packet using the flask dev server use this command:
+```bash
+python3 wsgi.py
+```
+The Flask debug mode flag can be set using via the config system explained above.
 
-1. ```pip install -r requirements.txt```
-2. `Create config.py` or set environment variables
-    - Several of these variables require keys and information, please reach out to an RTP for testing information
-3. Run `wsgi.py`
+Alternative you can run it through [gunicorn](https://gunicorn.org/) using this command:
+```bash
+gunicorn -b :8000 packet:app --access-logfile -
+```
 
+### CLI
+Packet makes use of the Flask CLI for exposing functionality to devs and admins. This is primarily designed to be used 
+locally with the target DB set via the server's config values.
 
-Commands
---------
+To use the CLI just set the project up as normal and then run the `flask` command in the project's root directory. 
+It'll automatically load up the app and show you a list of available commands. For more details on a particular command 
+use the help flag like this:
+```bash
+flask {command} --help
+```
 
-The flask CLI provides all the methods needed to setup a packet and a packet season
+**WARNING:** Be sure to double check which DB you're pointed at when using one of the admin or DB commands.
 
-```
-  create-packets  Creates a new packet season for each of the freshmen in the given CSV.
-  create-secret   Generates a securely random token.
-  db              Perform database migrations.
-  ldap-sync       Updates the upper and misc sigs in the DB to match ldap.
-  sync-freshmen   Updates the freshmen entries in the DB to match the given CSV.
-  fetch-results   Fetches and prints the results from a given packet season.
-```
+All DB commands are from the `Flask-Migrate` library and are used to configure DB migrations through Alembic. See their 
+docs [here](https://flask-migrate.readthedocs.io/en/latest/) for details.
