 ## 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.</Callout>

-    - **Go**: Enable [auto-indexing](/code-search/code-navigation/auto_indexing) and Sourcegraph will start indexing your dependencies.

-    - **Java, Scala, Kotlin**: Enable [auto-indexing](/code-search/code-navigation/auto_indexing) and set up a [JVM dependencies code host](/integration/jvm).
