Everybody knows WordPress. The famous open-source CMS (Content Management System) with the largest community on PHP programming language. There is a lot of themes and plugins available for it, for free and premium. Easy to use. Easy to develop.

Theme Check is to guide you to follow the standard. You could see the official theme of WordPress for reference such as Twenty Nineteen.

There are two files required for a theme, index.php, and style.css. Theme Functions are in functions.php. Make sure that they are just theme related. To extend more, you should make plugins for that.

Keep following its security standards. Make your theme ready for i18n (internationalization). Test your theme. Make a child theme if you only want to change some small aspects.

Plugin Development

To start to develop a plugin, go to wp-content > plugins, make a folder with your plugin name, eg: plugin-name. Inside that folder, create a file with the name same as the parent folder, eg: plugin-name.php. After that, go to your admin panel, activate your new plugin, then it will be activated. Refer to this documentation.

Maybe you need to install the plugin called Query Monitor. It would help you to debug your plugin.
