-Highlights
-----------
-
-* 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.

+There are a number of optional dependency groups you can install for extra functionality.
+These can be installed using ``pip install "zarr[<extra>]"``, e.g. ``pip install "zarr[gpu]"``
 
-    installation
+- ``gpu``: support for GPUs
+- ``fsspec``: support for reading/writing to remote data stores
+- ``tree``: support for pretty printing of directory trees

+conda
+~~~~~
+
+.. code-block:: console
+
+    $ conda install -c conda-forge zarr
+
+Conda does not support optional dependencies, so you will have to manually install any packages
+needed to enable extra functionality.
+
+Dependency support
+~~~~~~~~~~~~~~~~~~
+Zarr has endorsed `Scientific-Python SPEC 0 <https://scientific-python.org/specs/spec-0000/>`_ and now follows the version support window as outlined below:
+
+- Python: 36 months after initial release
+- Core package dependencies (e.g. NumPy): 24 months after initial release
+
+Development
+~~~~~~~~~~~
+To install the latest development version of Zarr, see `the contributing guide <contributing.html>`_.
