 ## Setting up code navigation for your codebase
 
 <Callout type="info">
-	There are several options for setting up precise code navigation listed
-	below. However, we always recommend you start by manually indexing your repo
-	locally using the [approriate
-	indexer](/code-navigation/writing-an-indexer#quick-reference) for your
-	language. Code and build systems can vary by project and ensuring you can
-	first succesfully run the indexer locally leads to a smoother experience
-	since it is vastly easier to debug and iterate on any issues locally before
-	trying to do so in CI/CD or in Auto-Indexing.
+	Auto-indexing is a fast way to get started, but for complex or
+	authenticated builds we recommend [running SCIP indexing in your CI
+	pipeline](/code-navigation/how-to/adding-scip-to-workflows). This reuses
+	your existing build configuration and secrets, delivering more reliable,
+	repeatable precise code navigation. For best results, verify the indexer
+	runs successfully on your machine first, then add it as a CI job.
