 The next step is to project the data into a graph within a remote session.
 The following example shows how to run a Cypher projection and xref:aura-graph-analytics/index.adoc#implicit-sessions[create a session] at the same time.
 
+To run the example, you must first set two query parameters called `clientId` and `clientSecret` to your link:https://neo4j.com/docs/aura/api/authentication/[Aura API keys].
+
+[NOTE]
+====
+It is good practice to use link:https://neo4j.com/docs/cypher-manual/current/syntax/parameters/[query parameters] for sensitive data such as credentials.
+This also removes the need to enter the same strings multiple times.
+
+In the Aura console, you can set query parameters within the link:https://neo4j.com/docs/aura/query/operations/#query-parameters[Query tool^].
+For other environments, see the link:https://neo4j.com/docs/cypher-manual/current/syntax/parameters[Cypher manual].
+====
+
 [IMPORTANT]
+====
 Make sure that the credentials you use here are the link:https://neo4j.com/docs/aura/api/authentication/[Aura API keys] (client ID and client secret), *not* your AuraDB credentials (username and password).
 
+Aura API keys examples:
+
+* Client ID: `n1lYYI2Zxxxxxxxxxxxxxxxxv1Cddvbp`
+* Client secret: `MduaDb4CxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxINtP_7Lt`
