+#### Major Dependencies
+Currently, the major dependencies that Neural Search depends on are [ML-Commons](https://github.com/opensearch-project/ml-commons) and [K-NN](https://github.com/opensearch-project/k-NN).
+Make sure to check on them when you observe a failure that affects Neural Search.
+See [Building on Lucene Version updates](#building-on-lucene-version-updates) as an example where K-NN caused a build failure.
+Also, please note that it may take time for developers to create a fix for your current dependency issue.

 ## Backwards Compatibility Testing
 
 The purpose of Backwards Compatibility Testing and different types of BWC tests are explained [here](https://github.com/opensearch-project/opensearch-plugins/blob/main/TESTING.md#backwards-compatibility-testing). The BWC tests (i.e. Restart-Upgrade, Mixed-Cluster and Rolling-Upgrade scenarios) should be added with any new feature being added to Neural Search.
