 Paths are pretty complex to reason about because, especially for a static site generator, they can come from so many places.
 
-The current browser URL? Technically a path. A full file path to a piece of content? Also a path. What about a slug for a piece of content? Yet another path.
+A full file path to a piece of content? Also a path. What about a slug for a piece of content? Yet another path.
 
 It would be silly to type these all as `string` and call it a day as it's pretty common to accidentally mistake one type of path for another. Unfortunately, TypeScript does not have [nominal types](https://en.wikipedia.org/wiki/Nominal_type_system) for type aliases meaning even if you made custom types of a server-side slug or a client-slug slug, you can still accidentally assign one to another and TypeScript wouldn't catch it.
 
@@ -12,13 +12,13 @@ Luckily, we can mimic nominal typing using [brands](https://www.typescriptlang.o
 
 ```typescript
 // instead of
-type ClientSlug = string
+type FullSlug = string
 
 // we do
-type ClientSlug = string & { __brand: "client" }
+type FullSlug = string & { __brand: "full" }
 
 // that way, the following will fail typechecking
-const slug: ClientSlug = "some random slug"
+const slug: FullSlug = "some random string"
 ```
 
 While this prevents most typing mistakes _within_ our nominal typing system (e.g. mistaking a server slug for a client slug), it doesn't prevent us from _accidentally_ mistaking a string for a client slug when we forcibly cast it.

 Here are the main types of slugs with a rough description of each type of path:
 
-- `ClientSlug`: client-side slug, usually obtained through `window.location`. Contains the protocol (i.e. starts with `https://`)
-- `CanonicalSlug`: should be used whenever you need to refer to the location of a file/note. Shouldn't be a relative path and shouldn't have leading or trailing slashes `/` either. Also shouldn't have `/index` as an ending or a file extension.
-- `RelativeURL`: must start with `.` or `..` to indicate it's a relative URL. Shouldn't have `/index` as an ending or a file extension.
-- `ServerSlug`: cannot be relative and may not have leading or trailing slashes.
 - `FilePath`: a real file path to a file on disk. Cannot be relative and must have a file extension.
+- `FullSlug`: cannot be relative and may not have leading or trailing slashes. It can have `index` as it's last segment. Use this wherever possible is it's the most 'general' interpretation of a slug.
+- `SimpleSlug`: cannot be relative and shouldn't have `/index` as an ending or a file extension. It _can_ however have a trailing slash to indicate a folder path.
+- `RelativeURL`: must start with `.` or `..` to indicate it's a relative URL. Shouldn't have `/index` as an ending or a file extension but can contain a trailing slash.
 
 To get a clearer picture of how these relate to each other, take a look at the path tests in `quartz/path.test.ts`.
