-#### How to create rdb file for a new ReJSON release?
-
-e.g., testing RDB compatibility with rejson 2.2.0.
-
-1. Run docker image redis-stack:
-   ```text
-   docker run -d -p 6379:6379 --name rejson redislabs/rejson:2.2.0
-   ```
-2. Load store.json and create a key named "store":
-   ```text
-   python3 utils/load_1file_hostport.py tst/integration/data/store.json store
-   ```
-3. Save rdb:
-   ```text
-   valkey-cli save
-   ```
-4. Copy out the RDB file:
-   ```text
-   docker cp $(docker ps -q):/data/dump.rdb tst/integration/rdb_rejson/rejson-<version>.rdb
-   ```
-5. run test_json_rdb_import.py:
-   ```text
-   TEST_PATTERN=test_import_rejson_rdbs make test
-   ```
