If you mean Common Lisp, I'd say install SBCL and start playing with with the repl. Choose the editor you know best; even notepad is useful to copy and paste expressions to/from the repl. Any editor that's suited for programming will have a way to send expressions to the repl with a keystroke, which is much more comfortable. So basically, just pick VSCode.
With that, you're ready to go. Take just one book and work through it, you don't need the best book, but a book will be better structured and more complete than multiple blog posts from different people. Practical Common Lisp (http://www.gigamonkeys.com/book/) is good and freely available. I used ANSI Common Lisp (http://www.paulgraham.com/acl.html), from Paul Graham (https://news.ycombinator.com/user?id=pg), long time ago and it's also good.
If you are open to non-common-lisp lisps, I'd say pick up clojure instead of common lisp, it's more modern and thus you will find more community and up-to-date resources. Clojure for the Brave and True is a book that has been praised, but I did not read it. It has some jokes and humorous examples that might or might not suit you.
