+<h1>ras-pi</h1>
+A comprehensive, end-to-end guide to the fundamentals of coding, network
+protocols, Linux, and the Raspberry Pi.
+
+<h2>Getting Started</h2>
+Run the following commands on a fresh installation on a Raspberry Pi:
+```
+sudo apt install git;
+git clone https://github.com/SLCPL-CreativeLab/ras-pi;
+cd ras-pi/scripts;
+sudo chmod a+x install.sh;
+sudo ./install.sh;
+
+# If you want to expose services to the internet, run this command as well.
+sudo ./cloudflared.sh;
+```
+
+<h3>Expose Services to the Internet</h3>
+To enable cloudflared to expose services to the internet, you must
+  - Make a Cloudflare account & purchase a domain;
+  - Run the command `cloudflared tunnel login`;
+  - Run the command ./cloudflared.sh in ~/ras-pi/scripts;
+
+To temporarily expose a single service to the internet, use this
+command: `cloudflared tunnel --url=http://localhost:PORT`, where
+PORT is the service you'd like to expose. The ports used with the
+standard services are:
+  - 5090 (the manual mirror of raspi.vintagecoding.net)
+  - 5091 (the AI web application)
+  - 5092 (the personal Netflix replacement)
+
+See `cloudflared.md` for more information.
