The toughest part about implementing a new plugin or framework is time spent browsing the documentation. Well-organized documentation is easy to find on larger projects – not so much on smaller releases.
Thankfully DevDocs has compiled all sources together onto one website. On DevDocs you’ll find the API/source documentation for everything from HTML & CSS to systems like Angular, Laravel, and Sass.
While this doesn’t contain every single project known to man, it does contain all the largest and most useful languages/frameworks for developers. There’s also a handy search bar to limit based on keywords related to your problem.
DevDocs is also completely free which makes it super handy for, well, every situation.
If you’d rather take it offline you can download copies locally to your machine.
The site even has a help page with keyboard shortcuts & tricks for navigating quicker.
And naturally this whole project has been released for free on GitHub so you’re able to contribute and even download a copy of the whole webapp locally for future reference.
