English [Auto] Welcome in this section we're going to transition from looking at the side of Wordpress development and start focusing on building plugins. The first thing we have to do is review that a theme determines how a site looks. Whereas a plugin extends WordPress functionality. So this raises the question of should code go in a function stop ph P file inside of a theme or should it go in its own plugin. Now what you'll find is a lot of the code that we write for plugins could also be executed within a theme's function stop ph P file. Ideally the thing you want to think about is this functionality something that you would want to keep on the site if someone changed themes. So if someone were to change themes they would lose all functionality inside of the function stop each file. If this is not something you want to happen then you want to take that functionality pull it out and put it into a plugin. However if this is functionality that will only ever work with this specific theme then it may make sense to include it in the function stop ph P until you start getting too much code at which point it may make sense to architect it as a plugin Instead of course sometimes it's perfectly clear when you need to write a plug in versus a theme. However we will start our exploration of building themes with some familiar code that you may find in a function stop file then we'll dive deeper into more specific concepts and code from there. So let's start off with looking at the basic files in code we need to start building a WordPress plugin.
