# Lambda Runtime

**Lambda Runtime** provides the facility to add/create docker runtime images. These runtimes then can be used as runtime for **Lambda** Functions. User can create as many docker images according to different use cases for different languages and different dependency versions.

Let us create a docker runtime image for pymongo with Python3.

To create a Lambda Runtime, go to **Code > Lambda Runtime** and click on **Add New** button. Enter the basic details - Name, Tag Name, Description, Select Interpreter (Python 3 in our case) and add the pymongo dependency in Dependencies tagged input field.

Finally, click on create button & save the details and wait for a few seconds for the image to be created.

You can use this docker image in **Lambda** as a runtime environment. Please refer to the **Lambda** section for its usage.
