 If you'd like a very detailed description of declaration files and how they work, I recommend perusing the [official documentation](https://www.typescriptlang.org/docs/handbook/declaration-files/introduction.html). But I will give a specific use-case walkthrough here.
 
-First, we need to find out which functions of the library we are actually going to use. If we look over the bump.lua documentation, we see that the library asks us to initialize a "world" using *bump.newWorld*, add rectangles to the world with *world:add*, and declare their movements using *world:move*.
