 ### Composed Subgraphs
 
-- You can only compose up to a **maximum of 5 source Subgraphs**
-- Composed Subgraphs can only use **datasources from the same chain**
-- **Nested composition is not yet supported**: Composing on top of another composed Subgraph isn’t allowed at this time
-- Aggregated entities can be used in composition, but the composed entities on them cannot also use aggregations directly
-- Developers cannot compose an onchain datasource with a Subgraph datasource (i.e. you can’t do normal event handlers and call handlers and block handlers in a composed Subgraph)
