Like LocalLLama subreddit is extremely helpful. You have to figure out what you want, what tools you want to use (by reading posts and asking questions), and then find some guides on setting up these tools. As you proceed you will run into issues and can easily find most of your answers in the same subreddit (or subreddits designated to the particular tools you're trying to set up) because hundreds of people had the same issues before.
Not to say that the article is useless, it's just semi-organized set of links.
