+# LINDI - Linked Data Interface
 
-Linked Data Interface (LINDI) - cloud-friendly access to NWB data
\ No newline at end of file
+warning: Please note, LINDI is currently under development and not yet operational.
+
+LINDI is a Python library that facilitates handling NWB (Neurodata Without Borders) files in an efficient, flexible manner that minimizes the need for excessive data downloads. Our goal is to enable composition of NWB files by integrating data from multiple sources.
+
+Key features include:
+
+- A read-only [Zarr store](https://zarr.readthedocs.io/en/stable/) for hdf5 files, including NWB (in progress)
+- Generation of a relatively small JSON file representing the NWB Zarr store, inspired by [kerchunk](https://github.com/fsspec/kerchunk).
+- An [h5py](https://www.h5py.org/)-like interface for accessing NWB Zarr stores that can be used with [pynwb](https://pynwb.readthedocs.io/en/stable/), although this feature is not yet functional.
+- The ability to assemble composite NWB files that draw from multiple sources, which is also not yet functional.
+
+This project was inspired by [kerchunk](https://github.com/fsspec/kerchunk) and [hdmf-zarr](https://hdmf-zarr.readthedocs.io/en/latest/index.html).
+
+## Installation
+
+Clone this repo and then
+
+```bash
+cd lindi
+pip install -e .
+```
+
+## Example usage
+
+```python
+import lindi
+import pynwb
+
+# Here's an example DANDI NWB file
+
+# https://neurosift.app/?p=/nwb&dandisetId=000717&dandisetVersion=draft&url=https://api.dandiarchive.org/api/assets/3d12a902-139a-4c1a-8fd0-0a7faf2fb223/download/
+h5_url = "https://api.dandiarchive.org/api/assets/3d12a902-139a-4c1a-8fd0-0a7faf2fb223/download/"
+
+
+# Create the read-only Zarr store for the h5 file
+store = lindi.LindiH5Store.from_file(h5_url)
+
+# Create the reference file system object
+rfs = store.to_reference_file_system()
+
+# For reference, save it to a file
+with open("example.zarr.json", "w") as f:
+    json.dump(rfs, f, indent=2)
+
+# Create the client from the reference file system
+client = lindi.LindiClient.from_reference_file_system(rfs)
+
+# Try to read using pynwb
+# (This part does not work yet)
+with pynwb.NWBHDF5IO(file=client, mode="r") as io:
+    nwbfile = io.read()
+    print(nwbfile)
+```
