Jack Kornfield introduces the Buddha’s Eightfold path in a short blog post. He points out that the Buddha’s path takes us to just this moment, in this place, wherever you are. You can find his post here: Where Does the Eightfold Path Go?
Lion’s Roar has a good introduction to the Eightfold path, and then provides links to articles on each aspect of the Eightfold path by teachers from several Buddhist traditions. You can find the introductory article and links here: What is the Eightfold Path?
Tricycle also has a good introduction to the Eightfold path, taken from the book “What the Buddha Taught,” by Walpola Sri Rahula. You can find the introductory article here: The Noble Eightfold Path Rahula’s book is often recommended as a great introduction to the Buddha’s teaching. If you can’t get to the Tricycle or Lion’s Roar links, you can find Dr. Rahula’s book online here: What the Buddha Taught
The chapter on the Eightfold path is Chapter 5, starting on p. 32 of the book.
