How to use it

At the right side every page you will find an Edit button, click on it and modify the text, then click Save (or press Control+S).

Use Markdown to format your text and put words inside [ ] to create internal links, then click on them and a new page will be created.


  1. Copy index.php to your web server
  2. Open index.php and customize details in $config variable
  3. Create a folder next to index.php with a very very long name (30 characters or more)
  4. Create a link in your browser to point to URL + FOLDERNAME. Example:
  5. Make sure that you have writing permissions in the Miki folder, every new Miki page is stored as a .txt file

Custom CSS styling

Create a link [customcss] so you get a page like and write the CSS code in it.
