-- For update deposits and withdrawals events use `yarn update:events {chainId}`
-- For update encrypted notes use `yarn update:encrypted {chainId}`
-- For update merkle tree use `yarn update:tree {chainId}`
+- To update deposit and withdrawal events use `yarn update:events {chainId} {optional: tokenOrEvent} {optional: tokenOrEvent}`
+- To update encrypted notes use `yarn update:encrypted {chainId}`

 #### NOTE!
 
-After update cached files do not forget to use `yarn update:zip`

 ### Example for Ethereum Mainnet:
 
-```
-yarn update:events 1
-yarn update:encrypted 1
-yarn update:tree 1
+You may set in [`networkConfig.js`](./networkConfig.js) the `blockSyncInterval` (def: 10_000) to the maximum value allowed by your RPC provider. Command usage follows below.
 
+```bash
+# Updating events with just the required chain id parameter
+yarn update:events 1
+# Updating events for only one token across all instances on that network
+yarn update:events 1 dai
+# Updating events for only one event on only some network
+yarn update:events 1 deposit
+# Both
+yarn update:events 1 dai deposit
+# Updating encrypted notes for some chain id
+yarn update:encrypted 1
+# Updating trees for some chain id
+yarn update:tree 1
+# Finally zips must be updated
 yarn update:zip
 ```
 
 ### Example for Binance Smart Chain:
 
-```
+```bash
 yarn update:events 56
+yarn update:events 56 bnb
+yarn update:events 56 bnb deposit
 yarn update:encrypted 56
-
+yarn update:tree 56
 yarn update:zip
