The next extension for the Redis challenge is now live: **Geospatial**.

Redis geospatial indexes let you store coordinates and query them efficiently. Built on top of Sorted Sets, they make it possible to perform operations like finding nearby points within a given radius.

By the end of this extension, your Redis implementation will support:

- Adding locations with `GEOADD`
- Querying locations with `GEOPOS`
- Calculating distances with `GEODIST`
- Searching for locations within a radius `GEOSEARCH`

Here’s the stage breakdown:

Please [give this a try](https://app.codecrafters.io/courses/redis/overview) and let us know how it can be improved! @UdeshyaDhungana (author of this extension) and I will be available here to help out with any tester or instruction-related issues.

I just want to say I love that you keep expanding the Redis challenge, it’s been the most fun and educational one so far 🙂
