 Install the JF CLI and authenticate package managers with Artifactory.
 
+There are two ways to authenticate with Artifactory:
+
+1. Using an admin access token
+2. Using OAuth configured via Coder [`external-auth`](https://docs.coder.com/docs/admin/external-auth/) feature. This is the recommended approach.
+
+Examples of both approaches are provided below.
+
+## Examples
+
+### Using an admin access token
+
 ```hcl
 module "jfrog" {
-    source = "https://registry.coder.com/modules/jfrog"
-    agent_id = coder_agent.example.id
-    jfrog_url = "https://YYYY.jfrog.io"
-    artifactory_access_token = var.artifactory_access_token # An admin access token
-    package_managers = {
-      "npm": "npm-remote",
-      "go": "go-remote",
-      "pypi": "pypi-remote"
-    }
+  source = "https://registry.coder.com/modules/jfrog"
+  agent_id = coder_agent.example.id
+  jfrog_url = "https://YYYY.jfrog.io"
+  artifactory_access_token = var.artifactory_access_token # An admin access token
+  package_managers = {
+    "npm": "npm",
+    "go": "go",
+    "pypi": "pypi"
+  }
 }
 ```

+### Using OAuth

+You can use OAuth to authenticate with Artifactory. This is the recommended approach. To use OAuth, you must have the Coder [`external-auth`](https://coder.com/docs/v2/latest/admin/external-auth#jfrog) configured with Artifactory.
