+# Base 64
+----------
+
+The `base64.h` header has only two functions, one to encode and one to decode to/from base 64.
+
+Example usage:
+```c
+char *recv_callback(arena_t *arena, buffer_t msg) {
+    buffer_t decoded = base64Decode(arena, msg);
+    alloc(arena, char); // allocate an extra char for the null pointer
+    return (char *)decoded.data;
+}
+
+buffer_t send_callback(arena_t *arena) {
+    char msg[] = "Hello World!";
+    buffer_t buf = {
+        .data = msg,
+        .len = arrlen(msg) - 1, // don't include the null pointer
+    };
+    buffer_t encoded = base64Encode(arena, buf);
+    return encoded;
+}
+
+int main() {
+    arena_t arena = arenaMake(ARENA_VIRTUAL, GB(1));
+    run_server(&arena, 8080, recv_callback, send_callback);
+    arenaCleanup(&arena);
+}
+```
