You have your own Blog? Perfect! Just share the link to your Post, choose a category, tag it and your Post will be indexed.
If you don't have a Blog, no problem, use the Texteditor to share your Code Examples. You can even link to your gists inside your text.
It's up to you how you share your Knowledge.
This is just a prototype - to show how it could work. You can contribute in any way. Give Feedback, share your Ideas about this and of course coding ;-)
Go to Posts to see how your Snippets could look like. If you want to add a snippet you need a account - just register or login with the test account: snippet/snippet
If you want to test it on your own machine, you can use the composer file from the distribution package - but there is still the documentation missing.
