How to convert my website to Composr cms

I have a education website: Học tiếng anh giao tiếp online

But it is hard to maintain. I see that Compo cms is quite good. So, how can i convert my website to Compo cms.

Thank you.

Hi,

It would very much depend what the site was built in.

If it was built by hand in HTML, each page would need converting by hand. You'd most likely copy and paste the HTML into new pages in Composr, with some edits to match whatever new theme styles used in your Composr theme's CSS.
If it is built in some other CMS, Composr would need an importer written for that particular CMS.
