 # mesh-catalog
 
-The `mesh-catalog` module of the mesh catalogue: claims the seat `mesh-catalog`.
+The `mesh-catalog` module of the mesh catalogue: deprecated. It no longer claims the seat `mesh-catalog`: the indexer of the delivery claims it and serves its verbs from the bus (ADR 0604). This module stays, with its tools, until it is retired.
