Your best suggestions to implement Google AMP ?

Try searching this forum for Ampproject because I have posted quite a few solutions as to how I implemented Ampproject and CodeIgniter.

My first post was way back in March 2016.

Remember to install the Ampproject browser plugin because W3.org validations do not work.

OK so I found 2 threads with 0 reply :

But it doesn't really help me because it just explains what AMP is. I'm rather looking for a solution to convert HTML to AMPHTML easily. For example through the cache output, making another AMP cache, through a converting library or something like that.

because when you have a project with millions of page, you can not really just do it manually...
