Let's a build a simple wiki

Let's create a simple wiki software.

This wiki will be very simple, not users auth, just the ability to display pages and create/edit new pages.

The wiki should have the following methods:

GET /page/{{$category/..}}/{{$page}}.md

If the page does not exist, it should redirect to edit page.

GET /edit/{{$category/..}}/{{$page}}.md

Will be used to both edit or create a new page.

POST /etc/{{$category/..}}/{{$page}}.md

Will change the page.

DELETE /etc/{{$category/..}}/{{$page}}.md

Will delete the page.

You are free to choose how to want to implement this. Once you have the basic implemented; see if you can add some meta data to the page. What about versioning of each page. Storing images and other types of media.
