+# deno-mkdirp
+
+`mkdir -p` 4 `deno`.
+
+## Import
+
+```ts
+import { mkdirp } from "https://deno.land/x/std/mkdirp/mkdirp.ts";
+```
+
+## API
+
+Same as [`deno.mkdir`](https://deno.land/typedoc/index.html#mkdir).
+
+### `mkdirp(path: string, mode?: number) : Promise<void>`
+
+Creates directories if they do not already exist and makes parent directories as needed.
