 ## Basic Rules
 
-- `$()` to turn refs into reactive variables
-- `$$()` to access the original refs from reactive variables
+- Ref-creating APIs have `$`-prefixed versions that create reactive variables instead. They also do not need to be explicitly imported. These include:
+  - `ref`
+  - `computed`
+  - `shallowRef`
+  - `customRef`
+  - `toRef`
+- `$()` can be used to destructure an object into reactive variables, or turn existing refs into reactive variables
+- `$$()` to "escape" the transform, which allows access to underlying refs
 
 ```js
-import { ref, watch } from 'vue'
+import { watchEffect } from 'vue'
 
 // bind ref as a variable
-let count = $(ref(0))
+let count = $ref(0)
 
-// no need for .value
-console.log(count)
-
-// get the actual ref
-watch($$(count), c => console.log(`count changed to ${c}`))
+watchEffect(() => {
+  // no need for .value
+  console.log(count)
+})
 
 // assignments are reactive
 count++
+
+// get the actual ref
+console.log($$(count)) // { value: 1 }
+```
+
+Macros can be optionally imported to make it more explicit:
+
+```js
+// not necessary, but also works
+import { $, $ref } from 'vue/macros'
+
+let count = $ref(0)
+const { x, y } = $(useMouse())
 ```
 
-### Shorthands
+### Global Types
 
-A few commonly used APIs have shorthands (which also removes the need to import them):
+To enable types for the macros globally, include the following in a `.d.ts` file:
 
-- `$(ref(0))` -> `$ref(0)`
-- `$(computed(() => 123))` -> `$computed(() => 123)`
-- `$(shallowRef({}))` -> `$shallowRef({})`
+```ts
+/// <reference types="vue/macros-global" />
+```
