+- `stateChanger.complete()`
+  - Designed to be called when you've reached the end of your list and there are no more items to fetch. This will render a "No more data" string, or the `no-data` slot.

 ### Props
 
-- `triggerLoad: () => Promise<void>` - **required** - The function to call when the user scrolls to the bottom of the list.
-- `loopTimeout: number = 1000` - optional - If the `loopMaxCalls` is reached within this duration (in milliseconds), a cool down period is triggered.
-- `loopMaxCalls: number = 5` - optional - The number of calls to the `triggerLoad` function within timeout which should trigger cool down period.
+- `triggerLoad: () => Promise<void>` - **required**
+  - The async function to call when we should attempt to load more data to show.
+- `intersectionOptions` - optional
+- The options to pass to the `IntersectionObserver` instance. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/IntersectionObserver/IntersectionObserver#options) for more details. Default is `{ rootMargin: "0px 0px 200px 0px" }`, making it trigger the `loadMore` function 200px before it actually intersects with the root element (window by default). This has the effect of beginning to load the next page of data before the user has actually reached the bottom of the list, making the experience feel more smooth.
+  - It may also be required to pass in a reference to your scroll container as the `root` option, if your scroll container is not the window.
+- `loopTimeout: number = 1000` - optional
+  - If the `loopMaxCalls` is reached within this duration (in milliseconds), a cool down period is triggered.
+- `loopMaxCalls: number = 5` - optional
+  - The number of calls to the `triggerLoad` function within timeout which should trigger cool down period.
 
 ### Slots
 
-- `loading` - Shown while calling `triggerLoad` and waiting on a response.
-- `no-results` - Shown when there are no results to display.
-- `no-data` - Shown when `stateChanger.complete()` is called, indicating the end of scroll.
-- `error` - Shown when there is an error. Slot has an `attemptLoad` prop passed to it which is the `triggerLoad` function, designed for a "Retry" button or similar.
+- `loading`
+  - Shown while calling `triggerLoad` and waiting on a response.
+- `no-results`
+  - Shown when there are no more results to display and we haven't fetched any data yet (i.e. data is less than count of items to be shown on first "page").
+- `no-data`
+  - Shown when `stateChanger.complete()` is called, indicating we've fetched and displayed all available data.
+- `error`
+  - Shown when there is an error or `stateChanger.error()` has been called. The slot has an `attemptLoad` prop passed to it which is just the internal `triggerLoad` function, designed for a "Retry" button or similar.
