+### Expanding {% data variables.product.prodname_codeql %} analysis
+
+You can expand {% data variables.product.prodname_codeql %} analysis coverage for all repositories in your organization that use default setup by configuring {% data variables.product.prodname_codeql %} model packs. Model packs extend the {% data variables.product.prodname_codeql %} analysis to recognize additional frameworks and libraries that are not included in the standard {% data variables.product.prodname_codeql %} libraries. This global configuration applies to repositories using default setup and allows you to specify model packs published via the container registry. For more information, see [AUTOTITLE](/code-security/code-scanning/managing-your-code-scanning-configuration/editing-your-configuration-of-default-setup#extending-coverage-for-all-repositories-in-an-organization).
