+# How to improve recipe run times with mod afterburner
+
+By default, every time you run a recipe against an LST, the full LST much be parsed and checked – even if no changes have been made against it. This results in recipes taking a decent amount of time to execute – regardless of how many times you've run recipes against the same LST or how complex those recipes are.
+
+Fortunately, we've recently added a new command that can significantly speed up repeated recipe runs against the same LST(s): [mod afterburner](../cli-reference.md#mod-afterburner).
+
+In this guide, we'll describe what this command does and provide you with an example of how you might use it to improve your CLI experience.
+
+## What `mod afterburner` does
+
+The `mod afterburner` command indexes certain parts (e.g., types) of the LST in order to speed up repeated recipe runs against the same LST.
+
+While not all recipes can benefit from this optimization, common ones – especially those frequently used in IDE integrations – often will. Some examples of recipes that will benefit from this include: find types, find method usages, and any high level recipe like upgrading Java or Spring Boot versions.
+
+:::info
+The generated indexes are internal to the CLI and may change between versions. They are intended **solely** for use by the CLI in subsequent run commands.
+:::
+
+## How to use it
+
+After you've built an LST, you can run the following command to index it so that future recipe runs against it are faster:
+
+```bash
+mod afterburner <path_to_repository>
+```
+
+Once that command is run, you can run any recipe as normal after it:
+
+```bash
+mod run . --recipe FindTypes -PfullyQualifiedTypeName="java.util.List"
+```
+
