+### Basic usage
+
+`encode` encodes a `Uint8Array` to RFC4648 base32 representation, and `decode`
+decodes the given RFC4648 base32 representation to a `Uint8Array`.
+
+```ts
+import { encode, decode } from "https://deno.land/std/encoding/base32.ts";
+
+const b32Repr = "RC2E6GA=";
+
+const binaryData = decode(b32Repr);
+console.log(binaryData);
+// => Uint8Array [ 136, 180, 79, 24 ]
+
+console.log(encode(binaryData));
+// => RC2E6GA=
