Update README.md

Updated "Setup" section to clarify that docker setup is unnecessary if using Heroku quick deploy, and restructured to include local setup instructions as well.

 - [A Heroku Account](https://www.heroku.com/)

 If deploying manually:
 - Docker ([Windows](https://docs.docker.com/docker-for-windows/install/), [macOS](https://docs.docker.com/docker-for-mac/install/), [Ubuntu](https://docs.docker.com/engine/install/ubuntu/), [other Linux distros](https://docs.docker.com/engine/install/binaries/))

 - [Heroku CLI](https://devcenter.heroku.com/articles/heroku-cli)

 ## Setup
+There are a few different ways to begin using the app, depending on your preferences:
+
+### A) Heroku Quick Deploy (Free)
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/benbusby/shoogle)
+
+### B) Manual Setup (non-Docker)
+Clone the repo and run the following commands to start the app in a local-only environment:
+
+```bash
+git clone https://github.com/benbusby/shoogle.git
+cd shoogle
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+./run
+```
+
+### C) Manual Setup (Docker) 
 1. Ensure the Docker daemon is running, and is accessible by your user account
   - To add user permissions, you can execute `sudo usermod -aG docker yourusername`
   - Running `docker ps` should return something besides an error. If you encounter an error saying the daemon isn't running, try `sudo systemctl start docker` (Linux) or ensure the docker tool is running (Windows/macOS).
 2. Clone and deploy the docker app using a method below:

 There are other methods for deploying docker containers that are well outlined in [this article](https://rollout.io/blog/the-shortlist-of-docker-hosting/), but there are too many to describe set up for each here. Generally it should be about the same amount of effort as the Heroku deployment.

-### Prevent Downtime (Heroku)
+### Prevent Downtime (Heroku only)
 Part of the deal with Heroku's free tier is that you're allocated 550 hours/month (meaning it can't stay active 24/7), and the app is temporarily shut down after 30 minutes of inactivity. Once it becomes inactive, any Shoogle searches will still work, but it'll take an extra 10-15 seconds for the app to come back online before displaying the result, which can be frustrating if you're in a hurry.
 
 A good solution for this is to set up a simple cronjob on any device at your home that is consistently powered on and connected to the internet (in my case, a PiHole worked perfectly). All the device needs to do is fetch app content on a consistent basis to keep the app alive in whatever ~17 hour window you want it on (17 hrs * 31 days = 527, meaning you'd still have 23 leftover hours each month if you searched outside of your target window).
