I want to use Lexical Editor for my website. So far I have used TinyMCE and it was easy to use: I downloaded TinyMCE, saved it on the server and inserted the necessary JS into my web pages.
But I don't understand the instructions on https://lexical.dev/docs/getting-started/quick-start how to use Lexical, where can I download it (to put it to the server) or how should I use it on my site?
