How to use the synth api correctly

[EzriLem]

This is a great project, and I really enjoy working with it! However, there are still some questions in the process of use. I self-deployed the maybe project on the server and simply entered Synth API key on the setup page. Through reading the Synth API, I find that I can realize the stock code and display the logo, etc., but how should I set up to realize the Logo display in my self-deployed project? Is there a detailed configuration document or a simple tutorial?
