+### Migrating from `.vscode/mcp.json`
+
+If your project uses `.vscode/mcp.json` (VS Code's MCP configuration format), migrate to `.mcp.json` for {% data variables.copilot.copilot_cli %}. The migration remaps the `servers` key to `mcpServers`.
+
+**POSIX shells (bash, zsh, fish, and others):**
+
+```shell
+jq '{mcpServers: .servers}' .vscode/mcp.json > .mcp.json
+```
+
+Requires [`jq`](https://jqlang.github.io/jq/).
+
+**PowerShell:**
+
+```powershell
+pwsh -NoProfile -Command "`$json = Get-Content '.vscode/mcp.json' -Raw | ConvertFrom-Json; `$content = ([pscustomobject]@{ mcpServers = `$json.servers } | ConvertTo-Json -Depth 100); [System.IO.File]::WriteAllText('.mcp.json', `$content, (New-Object System.Text.UTF8Encoding `$false))"
+```
+
+On Windows, replace `pwsh` with `powershell` if you are using Windows PowerShell instead of PowerShell Core.

 ## Skills reference
 
 Skills are Markdown files that extend what the CLI can do. Each skill lives in its own directory containing a `SKILL.md` file. When invoked (via `/SKILL-NAME` or automatically by the agent), the skill's content is injected into the conversation.

 ## Feature flag reference
 
-Feature flags enable functionality that is not yet generally available. Enable flags via the `COPILOT_CLI_ENABLED_FEATURE_FLAGS` environment variable (comma-separated list) or by using the `/experimental` slash command.
+Feature flags enable functionality that is not yet generally available. You can enable or disable individual flags in three ways:
+
+* **Environment variable**: Set `COPILOT_CLI_ENABLED_FEATURE_FLAGS` to a comma-separated list of flag names (for example, `"SOME_FEATURE,SOME_OTHER_FEATURE"`).
+* **Slash command**: Use `/experimental on` in an interactive session to enable all experimental-tier flags.
+* **Configuration file**: Add an `enabledFeatureFlags` object to `~/.copilot/config.json`. Set a flag to `true` to enable it or `false` to explicitly disable a flag that would otherwise be enabled by your tier.
+
+```json
+{
+    "enabledFeatureFlags": {
+        "SOME_FEATURE": true,
+        "SOME_OTHER_FEATURE": false
+    }
+}
+```
+
+> [!NOTE]
+> The legacy `feature_flags.enabled` array format is still supported as a fallback, but `enabledFeatureFlags` takes precedence when both are present.
