Port the extension for OpenCart3 to all versions of OpenCart 2.*, 1.*, 4.*

github.com/messor-network...

We are looking for an OpenCart specialist for constant cooperation.
Do not take it if you are not sure about the quality of execution or have not done it before.
Our extension was specifically written so that it was easy to port to any system. We use the JSON REST API to communicate with BacEnd
On FrontEnd, we have (html/css/VueJS) a completely independent interface - it does not have to be adjusted to different versions.

What we are waiting for at the output
A set of archives that will be installed on all versions of OpenCart
Set of instructions for porting
Example instruction
—-----
rename files in templates in tpl
Rename the directory to xxx
Add the install.php file to the root of the archive, etc.
—-----

So that we can port from new versions in the future.

Changes should affect only the files responsible for installing the module.
