If you're reading this, then you probably came from https://sthom.kiwi/my-projects. Thanks for checking this out.
Paste is a tiny pastebin clone that I wrote to learn the Rust programming language. It's a simple file upload/download
server, with minimal features and configuration.

Uploading pastes is as simple as writing a file and running a cURL command. Of course, you'll need my secret token ;)
cat my-cool-file.txt | curl -H "Authorization: Bearer <your-secret-token>" -F file=@- https://paste.sthom.kiwi

If you want to run it yourself, maybe try something from https://github.com/topics/pastebin instead.
If you're adamant to use this particular pastebin clone, then instructions are in the GitHub repo linked above.
