Welcome to the Always Learning wiki!

I created this wiki as a way of documenting difference frameworks, programming languages, and technologies that I learn and to teach others how to use them.

Most of the time documentation on different technologies are arranged in a way that make them confusing or difficult to follow. For example many documentation sites talk about a feature but don't provide code examples. So in order to understand that feature you have to go to multiple sites and put all the pieces together to get the full picture.

So I created this wiki as a way to overcome that problem. It's basically a cheat sheet for myself and hopefully it will help other people. Everything documented in this wiki is a framework, programming language or technology that I've personally used.

I don't plan on going over every detail of a technology. My goal is to go over the basics so you can quickly start to use the technology without getting discouraged at having to read a large amount of documentation.
