-## Cody Enterprise features
+## Setting up Cody Enterprise
 
-To cater to your Enterprise requirements, Cody offers the following features:
+You can set up Cody for your Enterprise instance by two methods:
 
-### IDE token expiry
+1. Sourcegraph Cloud
+2. Self-hosted Sourcegraph
 
-Site administrators can set the duration of access tokens for users connecting Cody from their IDEs (VS Code, JetBrains, etc.). This can be configured from the **Site admin** page of the Sourcegraph Enterprise instance. Available options include **7, 14, 30, 60, and 90 days**.
+## Cody on Sourcegraph Cloud
 
-![ide-token-expiry](https://storage.googleapis.com/sourcegraph-assets/Docs/token-expiry.png)
+With [Sourcegraph Cloud](/cloud/), you get Cody as a managed service, and you **do not** need to enable Cody as is required for self-hosted setup. However, by contacting your account manager, Cody can still be enabled or disabled on-demand on your Sourcegraph instance.
 
-### Guardrails
+## Self-hosted Sourcegraph Enterprise
 
-<Callout type= "note">Guardrails for public code is currently in Beta and is supported with VS Code and JetBrains IDEs extensions.</Callout>
+### Prerequisites
 
-Open source attribution guardrails for public code, commonly called copyright guardrails, reduce the exposure to copyrighted code. This involves implementing a verification mechanism within Cody to ensure that any code generated by the platform does not replicate open source code.
+- You have Sourcegraph version `5.1.0` or more
+- A Sourcegraph Enterprise subscription with [Cody Gateway](/cody/core-concepts/cody-gateway) or an account with a third-party LLM provider
 
-Guardrails for public code are available to all Sourcegraph Enterprise instances and are **disabled** by default. You can enable them from the Site configuration section by setting `attribution.enabled` to `true`.
+### Enable Cody on your Sourcegraph instance
 
-Guardrails don't differentiate between license types. It matches any code snippet that is at least **ten lines** long from the **290,000** indexed open source repositories.
+Site admins can only enable Cody on the Sourcegraph instance. To do so,
 
-### Admin controls
+- First, configure your desired LLM provider either by [using Sourcegraph Cody Gateway](/cody/core-concepts/cody-gateway) (recommended) or by directly using a third-party LLM provider
+- Next, go to **Site admin > Site configuration** (`/site-admin/configuration`) on your instance and set:
 
-<Callout type="note">Admin controls are supported with VS Code and JetBrains IDE extension.</Callout>
+```json
+    {
+      // [...]
+      "cody.enabled": true,
+      "completions": {
+        "provider": "sourcegraph"
+      }
+    }
+```
 
-Site administrators have selective control over users' access to Cody Enterprise, which is managed via the Sourcegraph role-based access control system. This provides a more intuitive user interface for assigning permission to use Cody.
+- Cody is enabled on your self-hosted Sourcegraph enterprise instance
 
-### Analytics
+## Disable Cody
 
-<Callout type= "note">Cody Analytics are supported with VS Code IDE extension and on the latest versions of JetBrains IDEs.</Callout>
+To turn Cody off:
 
-Cody Enterprise users can view analytics for their instance. A separately managed cloud service for Cody analytics handles user auth, gets metrics data from Sourcegraph's BigQuery instance, and visualizes the metrics data.
+- Go to **Site admin > Site configuration** (`/site-admin/configuration`) on your instance and set:
 
-The following metrics are available for Cody Enterprise users:
+```json
+    {
+      // [...]
+      "cody.enabled": false
+    }
+```
 
-| **Metric Type** |                                                                                                                                           **What is measured?**                                                                                                                                            |

+- Next, remove `completions` configuration if they exist
 
-To enable Cody Analytics:
+## Enable Cody only for some users
 
-- Create an account on [Sourcegraph Accounts](https://accounts.sourcegraph.com/)
-- A user already having a Sourcegraph.com account gets automatically migrated to Sourcegraph Accounts. Users can sign in to Cody Analytics using their email and password
-- Users without a Sourcegraph.com account should contact one of our team members. They can help with both the account setup and assigning instances to specific users
-- Map your user account to a Sourcegraph instance, and this gives you access to Cody analytics
+How to enable Cody only for _some_ users depends on what version of Sourcegraph you are running.
 
-### Multi-repository context
+### Sourcegraph v5.3+
 
-Cody supports multi-repository context, allowing you to search up to 10 repositories simultaneously for relevant information. Open a new chat, type `@`, and select `Remote Repositories.`
+In Sourcegraph v5.3+, access to Cody is managed via user roles. By default, all users have access.
 
-Keep @-mentioning repos that you want to include in your context. This flexibility lets you get more comprehensive and accurate responses by leveraging information across multiple codebases.
+First, ensure Cody is enabled in your site configuration. Go to **Site admin > Site configuration** (`/site-admin/configuration`) on your instance and set:
 
-### @-mention directory
+```json
+    {
+      // [...]
+      "cody.enabled": true,
+      // Make sure cody.restrictUsersFeatureFlag is not in your configuration! If it is, remove it.
+    }
+```
 
-To better support teams working with large monorepos, Enterprise users can `@-mention` directories when chatting with Cody. This helps you define more specific directories and sub-directories within that monorepo to give more precise context.
+<Callout type="info"> Ensure `cody.restrictUsersFeatureFlag` is **not** in your site configuration. If it is, remove it or else the old feature-flag approach from Sourcegraph 5.2 and earlier will be used.</Callout>
 
-To do this, type `@` in the chat, and then select **Directories** to search other repositories for context in your codebase.
+Next, go to **Site admin > Users & Auth > Roles** (`/site-admin/roles`) on your instance. On that page, you can:
 
-![@-mention-directory](https://storage.googleapis.com/sourcegraph-assets/Docs/cody-ent-at-mention-dir-1124.png)
+- Control whether users **by default** have access to Cody (expand `User [System]` and toggle **Cody** > **Access** as desired)
+- Control whether groups of users have access to Cody (`+Create role` and enable the **Cody** > **Access** toggle as desired)
 
-Please note that you can only `@-mention` remote directories (i.e., directories in your Sourcegraph instance) but not local directories. This means any recent changes to your directories can't be utilized as context until your Sourcegraph instance re-indexes any changes.
+### Sourcegraph v5.2 and earlier
 
-If you want to include recent changes that haven't been indexed in your Sourcegraph instance, you can `@-mention` specific files, lines of code, or symbols.
+In Sourcegraph v5.2 and earlier, you should use the feature flag `cody` to turn Cody on selectively for some users. To do so:
 
-## Supported LLM models
+- Go to **Site admin > Site configuration** (`/site-admin/configuration`) on your instance and set:
 
-Sourcegraph Enterprise supports different LLM providers and models, such as models from Anthropic and OpenAI. You can do this by adjusting your Sourcegraph instance configuration.
+```json
+    {
+      // [...]
+      "cody.enabled": true,
+      "cody.restrictUsersFeatureFlag": true
+    }
+```
 
-<FeatureParity type='ent' />
-For the supported LLM models listed above, refer to the following notes:
+- Next, go to **Site admin > Feature flags** (`/site-admin/feature-flags`)
+- Add a feature flag called `cody`
+- Select the `boolean` type and set it to `false`
+- Once added, click on the feature flag and use **add overrides** to pick users that will have access to Cody

-### Supported model configuration
+## Configure Cody for LLM providers
 
-Use the drop-down menu to make your desired selection and get a detailed breakdown of the supported model configuration for each provider on Cody Enterprise. This is an on-site configuration. Admins should pick a value from the table for `chatModel` to configure their chat model.
+Cody supports several LLM providers and models. You can access these models via the Cody Gateway, directly using your own model provider account or infrastructure.
 
-<FeatureParity type='configuration' />
+There are two ways of configuring Cody for LLM providers:
