+# Cosmoshub Validator Delegations Example
 
-This example subgraph stores `Delegation` objects that represent delegations being made in a Cosmos chain. In order to do that, the handler function checks all messages within the transaction and filters them in order to decode and save just the ones that represent a delegation in the chain.
-
-## Generating a manifest
-
-The subgraph is compatible with multiple Cosmos networks so before building the subgraph you need to generate a manifest file for the network of your choice. In case of the Cosmos Hub network, run the following command:
-
-```shell
-$ yarn prepare:cosmoshub
-```
-
-For the list of supported networks, see the scripts in the [`package.json`](package.json) file.
+This example subgraph stores `Delegation` objects that represent delegations being made in the Cosmos Hub chain. In order to do that, the handler function decodes `/cosmos.staking.v1beta1.MsgDelegate` messages.
