+# About
+
+<!--
+
+!IMPORTANT!
+
+Everything in this README between "# About" and "# Install" is automatically
+generated and will be overwritten the next time the doc generator is run.
+
+To make changes to this section, please update the @packageDocumentation section
+of src/index.js or src/index.ts
+
+To experiment with formatting, please run "npm run docs" from the root of this
+repo and examine the changes made.
+
+-->
+
+Collects all `Uint8Array` values from an (async)iterable and returns them as a single `Uint8Array`.
+
+## Example
+
+```javascript
+import toBuffer from 'it-to-buffer'
+
+// This can also be an iterator, generator, etc
+const values = [Buffer.from([0, 1]), Buffer.from([2, 3])]
+
+const result = toBuffer(values)
+
+console.info(result) // Buffer[0, 1, 2, 3]
+```
+
+Async sources must be awaited:
+
+```javascript
+import toBuffer from 'it-to-buffer'
+
+const values = async function * () {
+  yield Buffer.from([0, 1])
+  yield Buffer.from([2, 3])
+}
+
+const result = await toBuffer(values())
+
+console.info(result) // Buffer[0, 1, 2, 3]
+```
+
+# Install
+
+```console
+$ npm i it-queueless-pushable
+```
+
+## Browser `<script>` tag
+
+Loading this module through a script tag will make it's exports available as `ItQueuelessPushable` in the global namespace.

+```html
+<script src="https://unpkg.com/it-queueless-pushable/dist/index.min.js"></script>
