+## Routing
+
+The Universal Profile implementation allows for attaching multiple instances of Universal Receiver Delegate to it. This is due to LSP1 Routing. You could have a single General Purpose Unviersal Receiver Delegate and multiple instances of Specific Unviersal Receiver Delegate.
+
+A General Purpose Universal Receiver Delegate has its address stored under the [LSP1UniversalReceiverDelegate Singleton](../../standards//generic-standards/lsp1-universal-receiver-delegate.md#lsp1universalreceiverdelegate-singleton) data key. This contract will be called on any LSP1 hook, meaning that it can potentially react on any [TypeID](../type-ids.md#universal-receiver-type-ids).
+
+A Specific Universal Receiver Delegate has its address stored under the [LSP1UniversalReceiverDelegate Mapping](../../standards//generic-standards/lsp1-universal-receiver-delegate.md#lsp1universalreceiverdelegate-mapping) data key. This contract will be called on specific LSP1 hook, depending on the [TypeID](../type-ids.md#universal-receiver-type-ids) that was passed as a parameter in the hook, meaning that it only reacts on a single specific [TypeID](../type-ids.md#universal-receiver-type-ids).
