+```

 ## Managing Script Language Containers (SLCs)
 
 The Notebook Connector (NC) supports building different flavors of [Exasol Script Language Containers](https://github.com/exasol/script-languages-release) (SLCs) using the [script-languages-container-tool](https://github.com/exasol/script-languages-container-tool).
