 ### 1.x.x -> 2.x.x
 
+Starting with 2.0.0 we require Next 15 and Redis 5.
+
+Remove `redis` from your dependencies if you don't need anything other than `@redis/client`. Then install `@redis/client`.
+
+Upgrade Next and Redis in your project to:
+```
+"next": ">=15.2.4",
+"@redis/client": ">= 5.1.1"
+```
+
+OR if you need full `redis` package
+
+```
+"next": ">=15.2.4",
+"redis": ">= 5.1.1"
+```

 ## Installation
 
+If you come from Next 14 or below, ensure to flush Redis cache before you run the project with this library. Cache format between Next 15 and Next <14 are not compatible!

 ## Next 15 Support and migration from `@neshca/cache-handler`
 
 As `@neshca/cache-handler` does not officially support Next 15+ yet, we try to keep up with Next and prepare more or less temporary workarounds. At some point we will either create a fork of `@neshca/cache-handler` to fully support Next 15 or it gets updated by the maintainers. As for now we're building a set of decorators/workarounds you can use to build cache solutions for Next 15. We might need to do a full-blown rework which will be marked with a proper major version upgrade.
