 ### Terminology
 
 Here is some important terminology you should know if you're working inside VSCode:
-- A **URI** is a path to a file, like `/Users/.../my_file.txt`. 
 - An **Editor** is the thing that you type your code in. If you have 10 tabs open, that's just one editor! Editors contain tabs (or "models").
 - A **Model** is an internal representation of a file's contents. It's shared between editors (for example, if you press `Cmd+\` to make a new editor, then the model of a file like `A.ts` is shared between them. Two editors, one model. That's how changes sync.).
+- Each model has a **URI**, which is just a path to a file, like `/Users/.../my_file.txt`. (A URI or "resource" is generally just a path).
+
 - The **Workbench** is the wrapper that contains all the editors, the terminal, the file system tree, etc.
 - Usually you use the `ITextModel` type for models and the `ICodeEditor` type for editors. There aren't that many other types.
-- Often URIs are called **resource**.

 Actions or "commands" are functions you register on VSCode so that either you or the user can call them later. You can run actions as a user by pressing Cmd+Shift+P (opens the command pallete), or you can run them internally by using the commandService to call them by ID. We use actions to register keybinding listeners like Cmd+L, Cmd+K, etc. The nice thing about actions is the user can change the keybindings.

 We have a service `voidSettingsService` that stores all your Void settings (providers, models, global Void settings, etc). Imagine this as an implicit dependency for any of the core Void services:
