+Zarr-Python is a Python library for reading and writing Zarr groups and arrays. Highlights include:
 
-* Create N-dimensional arrays with any NumPy dtype.
-* Chunk arrays along any dimension.
-* Compress and/or filter chunks using any NumCodecs_ codec.
-* Store arrays in memory, on disk, inside a Zip file, on S3, ...
-* Read an array concurrently from multiple threads or processes.
-* Write to an array concurrently from multiple threads or processes.
-* Organize arrays into hierarchies via groups.
+* Specification support for both Zarr v2 and v3.
+* Create and read from N-dimensional arrays using NumPy-like semantics.
+* Flexible storage enables reading and writing from local, cloud and in-memory stores.
+* High performance: Enables fast I/O with support for asynchronous I/O and multi-threading.
+* Extensible: Customizable with user-defined codecs and stores.
