-## Hints and Tips
-For a connection profile, Hyperledger Composer looks for a `connection.json` file in the user's `<HOME>/.composer-connection-profiles`
-directory.  
-
-e.g. If your connection profile is specified in `<HOME DIR>/.composer-connection-profiles/auction-app/connection.json` then you
-would need to specify `auction-app` as your connection profile.
-
-Additionally the business network identifier that you'll need to specify is that which the business network was deployed with.
-Here is an example connection.json profile:
-```
-{
-    "type": "hlf",
-    "keyValStore": "/Users/me/.composer-credentials/kvs",
-    "membershipServicesURL": "grpc://some.ip.address.here:7054",
-    "peerURL": "grpc://some.ip.address.here:7051",
-    "eventHubURL": "grpc://some.ip.address.here:7053",
-    "deployWaitTime": 300,
-    "invokeWaitTime": 10,
