It assumes you have\nknowledge of how to write code in a notebook environment.\n\nOverview\n--------\n\nGemini in Colab Enterprise can help you explain code cells\nin a Colab Enterprise notebook. You might want to do this when you're working\nwith someone else's notebook and want to get a quick understanding of what\nthe code does. Or you might need to remind yourself how parts of your notebook\nwork after a long period of time without working on it.\n\nAfter you get an explanation of a code cell, you can browse any\nincluded code snippets and review the sources. You can also use the\n**Explain code** chat dialog to discuss the code and ask follow-up questions.\nFor more details, see [Explain a code cell](#explain).\n\nBefore you begin\n----------------\n\n| As an early-stage technology, Gemini for Google Cloud\n| products can generate output that seems plausible but is factually incorrect. We recommend that you\n| validate all output from Gemini for Google Cloud products before you use it.\n| For more information, see\n| [Gemini for Google Cloud and responsible AI](/gemini/docs/discover/responsible-ai).\n\n1.

Users who are granted the `dataform.repositories.list` permission or the [Code Creator\n| (`roles/dataform.codeCreator`)](/iam/docs/understanding-roles#dataform.codeCreator) role in a project can list the names of code assets in that project by using the Dataform API or the Dataform command-line interface (CLI). Non-administrators using BigQuery Studio can only see code assets that they created or that were shared with them.\n\nExplain a code cell\n-------------------\n\nTo explain a code cell using Gemini for Google Cloud,\ndo the following:\n\n1. In the Google Cloud console, go to\n the Colab Enterprise **My notebooks** page.\n\n [Go to My notebooks](https://console.cloud.google.com/vertex-ai/colab/notebooks)\n2. In the **Region** menu, select the region that contains your notebook.\n\n3. Click the notebook that you want to open.\n\n4. In your notebook, click a code cell that has code in it.\n\n5. Click\n spark **Available\n AI features** , and then click **Explain code**.\n\n An **Explain code** chat dialog appears that includes\n an explanation of your code.\n6. Read through the explanation, browse the example code snippets,\n and review the sources. Use this chat dialog to discuss the code and\n ask follow-up questions.\n\n7. To close the **Explain code** dialog, click\n close **Close**.\n\nTurn off Gemini in Colab Enterprise\n-----------------------------------\n\n\nTo turn off Gemini in Colab Enterprise for a\nGoogle Cloud project, an administrator must turn off the\nGemini for Google Cloud API. See\n[Disabling services](/service-usage/docs/enable-disable#disabling).\n\n\nTo turn off Gemini in Colab Enterprise for a specific user, an\nadministrator needs to revoke the\n[Gemini for\nGoogle Cloud User](/iam/docs/understanding-roles#cloudaicompanion.user) (`roles/cloudaicompanion.user`) role for that user. See\n[Revoke\na single IAM role](/iam/docs/granting-changing-revoking-access#revoke-single-role).\n\nWhat's next\n-----------\n\n- Read the [Gemini for Google Cloud\n overview](/gemini/docs/overview).\n\n- For more ways to write and edit code with Gemini\n assistance, see the following:\n\n - [Chat about your notebook with Gemini](/colab/docs/chat)\n - [Use code completion and code generation](/colab/docs/use-code-completion)\n - [Explain and fix errors](/colab/docs/explain-errors)\n - [Use the Data Science Agent](/colab/docs/use-data-science-agent)\n- Learn [how Gemini for Google Cloud uses\n your data](/gemini/docs/discover/data-governance)."]]
