How to create module in version-16.0.0 without using Builder

I am new to dolibarr. I was going through the module development document and I found we have to copy modMyModule.class.php file from dev/skeletons folder. I guess in version 16.0.0, dev folder is removed. Is there is any updated documentation available. Or I am searching it in wrong place. Can anyone help me to find out the way

Hello,

You need to use the Module Builder to create modules.

There is no option to create without builder?

It’s easier with the builder, but if you want to do it manualy, you have the module skeleton on the modulebuilder directory : dolibarr/htdocs/modulebuilder/template at develop · Dolibarr/dolibarr · GitHub

Thanks for the response. I found it. Is there is any document which explain the file structure to create new theme?
