 ## API
 
+### alloc(size)
+
+Create a new `Uint8Array`. If `globalThis.Buffer` is defined, it will be used in preference to `globalThis.Uint8Array`.
+
+#### Example
+
+```js
+import { alloc } from 'uint8arrays/alloc`
+
+const buf = alloc(100)
+```
+
+### allocUnsafe(size)
+
+Create a new `Uint8Array`. If `globalThis.Buffer` is defined, it will be used in preference to `globalThis.Uint8Array`.
+
+On platforms that support it, memory referenced by the returned `Uint8Array` will not be initialized.
+
+#### Example
+
+```js
+import { allocUnsafe } from 'uint8arrays/alloc`
+
+const buf = allocUnsafe(100)
+```
