+# Video Streaming Proof of Concept
+
+This project is a demo for streaming video output from multiple "client" devices to one "server". This is a basic demo
+of what sauron-cv seeks to accomplish.
+
+## Installation
+
+It is strongly recommended that you use a virtual environment. These instructions will assume you are using venv, you
+can substitute this with your preferred environment management. You will need to make sure that the `virtualenv` package
+is installed globally, either via pip or the `python3-virtualenv` package in your system package manager.
+
+When first cloning this repo, run the following:
+
+```shell
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+This will create a virtual environment, enter that virtual environment, and install the required packages.
+
+If you start a new shell, you will need to re-enter the virtual environment:
+
+```shell
+source .venv/bin/activate
+```
+
+## Running
+
+### Client
+
+To run the client with a localhost target:
+
+```shell
+python -m client
+```
+
+To target an external server, provide its IP address using the `-s` flag:
+
+```shell
+python -m client -s [server IP address]
+```
+
+### Server
+
+```shell
+python -m server
+```
+
+### Common Flags
+
+Make sure that these match between your client and server!!
