 ### Copilot auth
 
+**Individual accounts** (Pro, Pro+, Free):
+Detected from:
+- `~/.local/share/opencode/copilot-usage-token.json`
+- `~/.local/share/opencode/auth.json` with a `github-copilot` entry
+- `~/.config/opencode/copilot-quota-token.json` (optional override)
+
+**Enterprise/Organization accounts**:
+Requires configuration in `usage-config.jsonc` (see above). The plugin will:
+1. Check for `copilotEnterprise` config
+2. Use enterprise/org metrics API if configured
+3. Fall back to individual quota checking if enterprise metrics are unavailable
+4. Automatically use GitHub CLI token if no explicit token is provided
+
+**Enterprise Prerequisites**:
+- "Copilot usage metrics" policy must be set to **Enabled everywhere** for the enterprise
+- Token requires appropriate permissions:
+  - Fine-grained PAT: "Enterprise Copilot metrics" (read) or "Organization Copilot metrics" (read)
+  - Classic PAT: `manage_billing:copilot` or `read:enterprise` / `read:org`
+- GitHub Enterprise Cloud account with Copilot Enterprise or Copilot Business
+
 Copilot is detected from either of these locations:
 
 - `~/.local/share/opencode/copilot-usage-token.json`
