-The `model-sync` gradle plugin synchronizes models between `model-api` endpoints.
+The `bulk-model-sync` Gradle plugin synchronizes models between `model-api` endpoints.
 A common example would be synchronizing a local MPS project to a `model-server`.

+IMPORTANT: For correct synchronization the used model-server is required to use IDs for roles. This can be achieved by starting the model-server with the `-useroleids` flag.

 It allows the definition of sync directions by specifying source and target endpoint.
 Based on these directions, Gradle tasks will be generated, which can be run to trigger the corresponding synchronization.
 
-Internally, the node data will be bulk exported from the source endpoint and stored as json files.
-After that, those json files serve as a specification to incrementally update the target model through via the target `model-api` endpoint.
+Internally, the node data will be bulk exported from the source endpoint and stored as JSON files.
+After that, these JSON files serve as a specification to incrementally update the target model via the target `model-api` endpoint.
 This means that only a minimal amount of write operations is used to update the target model.
