 After getting these up and running there are some setup tasks to do. Rename config.py-default to config.py and open the file in a text editor. You need to add:
 
 1) Your Twitter access tokens: You can find a good guide for doing this here - https://iag.me/socialmedia/how-to-create-a-twitter-app-in-8-easy-steps/ You will need to pick a unique name for the app. Which is annoying. Pick anything you want that isn't taken. Maybe add your name at the end.

 3) Change the colours if you want: Theme support is detailed below
 
 When you've setup your config.py you can run the script like this example that grabs your home timeline:
 
 `python3 teletext-twitter -t` (add -h to show options - also listed below)

 All of the files in that folder are sent across to the TV every so often, therefore the script constantly overwrites it with new tweets (up to 5 - space permitting!) so that it will update on your screen.
