 ### Persistent services
 
-The following table displays the list of **persistent** services created as part of the on-premises installation:
-
-| Database      | Purpose | Required version     |
-| :---        | :----   |  :--- |
-| MongoDB      | Stores all account data (account settings, users, projects, pipelines, builds etc.)       | 7.x   |
-| Postgresql   | Stores data about events for the account (pipeline updates, deletes, etc.). The audit log uses the data from this database.        | 16.x or 17.x      |
-| Redis   | Used for caching, and as a key-value store for cron trigger manager.        | 7.0.x      |
-| RabbitMQ  | Used for message queueing.        | 3.13 \| 4.0.x      |
+Codefresh relies on several persistent services to store its data:
+
+- **MongoDB**: Stores all account data (account settings, users, projects, pipelines, builds etc.)
+- **PostgreSQL**: Stores data about events for the account (pipeline updates, deletes, etc.). The audit log uses the data from this database.
+- **Redis**: Used for caching, and as a key-value store for cron trigger manager.
+- **RabbitMQ**: Used for message queueing.

+The following table reflects the recommended and supported versions of these databases for different Codefresh releases:
