Learn to Code Over 10 Tutorials
From Award-Winning Teacher Michael Hartl

Get started coding fast… with access to all 10 Learn Enough courses: online books + streaming video, progress tracking, exercises, and certificates of completion. Includes the Ruby on Rails Tutorial online book and videos (print edition published by Addison-Wesley). Get help with community exercise answers and a private Slack chat group.

Individual tutorials and downloads also available à la carte.

I’ve been working as a Rails developer for 2.5 years now. My first dev job actually used a copy of Learn Enough’s Rails tutorial as its training manual. The fact that I’d already completed the tutorial before applying meant that I was weeks/months ahead of the curve. I can’t recommend these tutorials highly enough. For me (and my wife, who’s also a Learn Enough–trained web developer), they were life-changing.

Learn the most valuable skill in the 21st Century

Learning to code may just be the most valuable skill you can learn in the 21st Century. The Learn Enough online courses get you there by creating a solid foundation and then building all the way to a professional-grade web application that works like Twitter.
You learn fundamentals that can help you solve harder problems.

Since I started coding 2 years ago, I have paid thousands of dollars for Udemy, Skillshare, Frontend Masters, etc., etc., and this is by far the best content I have seen yet. Thanks for all your hard work!

Just completed the whole tutorial, and I feel I’ve developed a new super power. Amazing book, it explains the concepts clearly and illustrates them with powerful examples, I have taken rails tutorials before, but this book gave me the basis to fully understand and be able to code in rails effortlessly.

Well, just wanted to say thank you. Best tutorial as far as I know on RoR. See you on twitter.

My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP… This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on Rails Tutorial is what I used to switch back to Rails again… Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it.

— Damian H.

I’ve just completed all 14 chapters of the Ruby on Rails Tutorial, and I’m very, very satisfied with the results. I’ve been a very active software engineer since the late 70’s, always staying up with current technologies, and having a ball along the way. The way I like to do tutorials is to type in every line of code myself, read the material at least twice, and do all exercises. Your tutorial has been more than worth that effort!

I’ve taken many ‘tutorials’ in the last 40 or so years, and I have come to expect that the tutorial writer ‘burns out’ somewhere around the middle of the tutorial, and it gets worse as the pages wear on. It is quite clear to me that you applied all your tools that you’ve used in preparing your physics class materials, and brought them with you to this work of yours. I am grateful for your effort, your attention to detail is simply amazingly consistent from start to finish. This tutorial has greatly aided in my transitioning from desktop / cpp to distributed apps / ruby.

Thanks to you, I feel that I have been very effectively jump-started into my role as principal engineer of my tiny new company, and hopefully will have a ball with this technology for at least another decade.

With great thanks,

About the Git Tutorial

Going through Git is wonderful. I am actually learning… I’ve done three other Git tutorials and still felt so lost. Doing it all now makes so much sense. It’s like a light bulb.

— Janelle S.

Michael does a great job of structuring this tutorial and thrusts the users quick into the world of Git with real examples and a hands-on approach. Just one of a series of great books. Highly recommended.

— Satisfied Reader

Thanks to the Git skills I started building with your tutorial, I now run Git workshops to teach other students this great tech.

— Eric Z.

I stumbled upon your website by luck a couple weeks back and since then I have gone through the Developer Fundamentals series, which I have to say exceeded my expectations and filled in many gaps in my knowledge which multiple other online tutorials failed to do.

I want to thank you for the amazing job you have done with the tutorials. They are likely the best tutorials I have ever read.

— Pedro I.

I have been trying to learn web development and programming on and off for the past 3 years and your website is the first one that I feel does the job right.

— Janelle S.

Just bought the new ebook and want to say keep up the great work!! The Learn Enough to Be Dangerous series re-ignited my desire to code after 10+ years of “meh”.

— Diane Y.

The Learn Enough Society and the courses are incredible. It’s the best value in the market of online courses in my opinion. Like you say, it’s learning to tech, which is very useful in our world.

— Sébastien D.

I just meant to tell you: your tutorial books from the Learn Enough series are awesome! The books are well-written, clear, concise, super-useful, and even fun to read. Thank you so, so much for this! I have bought the first three and will buy whatever you publish next. Keep up doing this very good work and thanks again.

— Pierre W.

Have been following the whole “Learn Enough to Be Dangerous” series and am VERY impressed with it. I am a project manager who works with software developers daily. These sessions have provided me with a huge amount very useful information, to the extent that I now not only understand what the dev guys are talking about, but am starting to use the tools (command line, Git, etc.) that they use.

— Brian

Michael Hartl is one of the best educators around when it comes to web development. I have been following him for a long time, and everything he produces is top quality. If you are looking for a quick way to become a thorough and productive professional web developer, Hartl’s books are a great place to start.

Hi, my name is Philip, and I’m a beginning learner of web development. I’ve dabbled in small ways in Ruby/Rails for about a year and a half. Occasionally, I write ruby scripts to solve problems at my job. I also dabble in learning: JavaScript, Ember, more Ruby/Rails, brief intro readings into Scala.

I’ve tried Codeschool, Codecademy, and I’ll stop there, so you don’t spend the next 3 hours reading all the different learning resources I’ve tried.

Ruby on Rails Tutorial (Rails 5) is undoubtedly, the most effective and educational resource I’ve ever come across when it comes to learning anything about web development or writing any code on any level.

Here’s what you seem to understand that everyone else just gets wrong: There’s a big spectrum between the very beginner basics: declaring variables, to voodoo, magical, incantational trickery of witchcraft, like building your own web server.

Almost all tutorials make this mistake. The first couple “lessons” are good for people who don’t even have a clue what computer programming is and then suddenly, there’s a big jump to what seem to be concepts that only seasoned developers have mastered.

Thanks for such a great, educational guide in Ruby on Rails.

— Philip
