 We work with API proposals on which we iterate a few times before making stable API. Those proposals can be tested by extension authors. The proposed API is defined in [`vscode.proposed.d.ts`](https://github.com/Microsoft/vscode/blob/master/src/vs/vscode.proposed.d.ts). This is what you have to do to try out a proposed API:
 
 * You must use [Insiders](https://code.visualstudio.com/insiders/) because proposed APIs change frequently.
-* You must have this line in the package.json file of your extension: `"enableProposedApi": true.`
+* You must have this line in the package.json file of your extension: `"enableProposedApi": true`.
 * Copy the latest version of the [`vscode.proposed.d.ts`](https://github.com/Microsoft/vscode/blob/master/src/vs/vscode.proposed.d.ts)-file into your project.
 
 Note that you cannot publish an extension that uses a proposed API. We may likely make breaking changes in the next release and we never want to break existing extensions.
