Readme to the Module Contact me for Joomla 5

Even though there are already a lot of modules written for Joomla, I have not been able to find a Contact module that is suitable for me.
Most probably - this is only the first version of the module. I plan to improve it to perfection.
You can see the current version of the working module on my CV site, the module code in the repository.
File structure + Language files:

You can install the module in the standard method:
System -> Install Extensions -> Upload Package File.
In the module settings add a position for module output and published it:

As a result, a form should appear on the selected position:

I planned to add the ability to customize in the Joomla admin: the choice of fields, which to display in the module, adding styles for fields, email to which to send emails, perhaps a few more settings.
