# Libraries

Code Repositories allow you to use local and external libraries, as well as share your own code within your Foundry environment. Different languages require different steps to share and use libraries:

### Python

* [Share Python libraries](../../transforms-python/share-python-libraries/index.md)
* [Discover and use shared Python libraries](../../transforms-python/use-python-libraries/index.md)

### Java

* [Share Java Code & Macros](../../transforms-java/share-code/index.md)
