 This worked fine for a while, and it had the added bonus
 that ArgoCD is reading from the same manifest git repository.

 Git will still be used as an *output* of kuberpult, but not as the source of truth.

 ## Preparation
 
 Our recommendation is to enable the database mode in 2 steps:
 
 ### Step 1: writeEslTableOnly=true
 
 Enable the Database with `db.dbOption: "postgreSQL"` and `db.writeEslTableOnly: true`.
+This requires kuberpult version <= 10.3.10.
 This means that kuberpult will connect to the DB, but only write one table.
 Kuberpult will not read from the database in this state,
 so the manifest-repository is still considered the source of truth.
