Can you use it commercially?
Free to use. Anything you distribute that includes it must be open-sourced under the same licence. Running it as an online service also counts, so a hosted version must offer its source.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
Docker deployment is the easiest way to set up SiYuan on a server.
Follow the official instructions in the project README.
