+KvikIO (pronounced "kuh-VICK-eye-oh", see [here](https://ordnet.dk/ddo_en/dict?query=kvik) for pronunciation of kvik) is a Python and C++ library for high performance file IO. It provides C++ and Python
 bindings to [cuFile](https://docs.nvidia.com/gpudirect-storage/api-reference-guide/index.html),
 which enables [GPUDirect Storage (GDS)](https://developer.nvidia.com/blog/gpudirect-storage/).
 KvikIO also works efficiently when GDS isn't available and can read/write both host and device data seamlessly.
@@ -15,9 +15,92 @@ The C++ library is header-only making it easy to include in [existing projects](
 * A Python [Zarr](https://zarr.readthedocs.io/en/stable/) backend for reading and writing GPU data to file seamlessly.
 * Concurrent reads and writes using an internal thread pool.
 * Non-blocking API.
-* Handle both host and device IO seamlessly.
+* Transparently handles reads and writes to/from memory on both host and device.
 * Provides Python bindings to [nvCOMP](https://github.com/NVIDIA/nvcomp).

+import cupy
+import kvikio
+
+def main(path):
+    a = cupy.arange(100)
+    f = kvikio.CuFile(path, "w")

+    b = cupy.empty_like(a)
+    f = kvikio.CuFile(path, "r")
+    # Read whole array from file
+    f.read(b)

+        # Note: must wait for futures before exiting block
+        # at which point the file is closed.
+        future1.get()  # Wait for first read
+        future2.get()  # Wait for second read
+    assert all(a == d)

+#include <kvikio/file_handle.hpp>
+using namespace std;
+

+    future<size_t> future = f.pread(b_dev, sizeof(a), 0);  // Non-blocking
+    size_t read = future.get(); // Blocking
+    // Notice, `f` closes automatically on destruction.
