Flakes is intended to be used for business facing web applications. If you're building an internal tool to help your sales team manage leads or are building an inventory tracking solution for your watch business, you'll need Flakes.
Flakes is a starting point, It helps you get a quick start. It is not a collection of everything you'll ever need and it doesn't aim to become one.
Flakes is a collection of components. These components follow the Flakes aesthetic and go well together. Since these components are low level abstractions like forms and grids, you really can build almost anything you'll need.
I've built a few example layouts for you play around with. Check out the example layouts using the navigation to your left to get a feel for what is possible.
Until now, Flakes has been a one man show with me designing and developing for it. When you work on something for long enough, you'll run out of ideas on how to improve it. If you are keen on contributing I'd love to have you make a pull request with your change. If it's a sufficiently big change, I'd recommend filing an issue on Github to discuss the change to avoid duplicate or unnecessary work.
If you need help with something the documentation does not cover, send me an email and I'd be happy to help you. firstname.lastname@example.org
Please report all bugs on the Github issues page. If you have some time, I'd appreciate it a whole lot more if you could make a pull request with a fix.
