Tech is the New Literacy

Everyone knows how important technical skills are. Tech is power. Tech is freedom. Not knowing tech can be a source of fear and insecurity. But there’s so much to learn that it can be truly overwhelming. Where do you even start?

Learn Enough is based on the idea that you don’t have to learn everything to get started—you just have to learn enough to be dangerous. By teaching you the technical skills you need in the shortest time possible, the Learn Enough tutorials help you take your career to the next level—or start a new career entirely.

Are you ready to Learn Enough to be dangerous?

How Learn Enough Works

We’ve got options for your learning

At Learn Enough, we offer books, videos, and online course subscriptions to teach you the most important parts of the most important subjects. We’ll sometimes refer to this as “learning to code”, but it’s really much more than that. Learning tech means learning the tools and technologies used by software developers as well as learning “soft” skills like Technical sophistication The ability to figure out tech problems on your own, including concrete skills like coding, as well as fuzzy skills like Googling the error message and knowing when to just reboot the darn thing —which can often be harder to learn than the “hard” skills!

The Learn Enough All Access Bundle includes the entire Learn Enough introductory sequence and the full Ruby on Rails Tutorial. That’s 9 tutorials with over 2500 pages of content and 53 hours of video covering Command Line, Text Editor, Git, HTML, CSS & Layout, JavaScript, and Ruby, along with a comprehensive introduction to building professional-grade web applications with Ruby on Rails.

How We Teach

Our method of teaching involves working on real projects using the actual tools used every day by software developers. At every point, you’ll know why you’re doing what you’re doing and the ultimate goal you’re aiming for.

Some other courses try to guide you through challenging subjects entirely in a web browser. One advantage of this in-browser approach is that there is much less that can go wrong—but the downside is that in real life, things go wrong all the time. Instead of shielding you completely from such errors, Learn Enough treats each one as a valuable opportunity for improving your understanding.

This learning approach is based on the teaching experience of the principal instructor at Learn Enough: Michael Hartl, creator of the Ruby on Rails Tutorial and author or coauthor of 10 different Learn Enough tutorials. As a graduate student, Michael taught the core physics curriculum at Caltech, where he was a popular instructor with the students and received a Lifetime Achievement Award for Excellence in Teaching. Now he’s applying his teaching skills to help you learn enough tech to be dangerous. Meet the Learn Enough Founders

It’s an Amazing Series of Tutorials

But Don’t Just Take Our Word for it...

Q: What is Jimmy Wales' favorite book?

A: It changes often. At the moment, it’s Ruby on Rails Tutorial by Michael Hartl. :)

About the Command Line Tutorial

Michael Hartl’s guide to the command line is an awesome tutorial for beginners and a great refresher for experienced programmers as well.

I bought the Learn Enough command line program and videos last fall, and it’s paid off sooooo many times in my new job. During my first week, I had a manager sitting right beside me giving me the “go here, go there, do this, etc.” Having watched, read, and done the exercises, I was confident in getting around the CLI—and even had him asking, ”What was that shortcut?” For this, I thank you. Now I need a “Learn even more CLI to be dangerouser.”

— Thomas Thackery

I’m just writing to say I enjoyed Learn Enough Command Line to Be Dangerous. I’m a senior CS student and was actually already familiar with the UNIX console, however, I didn’t find your book boring or tedious at any point, quite the contrary! It was a nice refresher of the basics, and I actually learned some new tricks (being able to search inside the manpages for instance). The chapter + exercise format was effective in solidifying concepts for me.

— 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.

About the Ruby on Rails Tutorial

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.

— Mauricio Guzmán


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

— Robert Hopman


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.

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,

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.

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
