+- You can use a custom link syntax for references to TypeScript code which will

+
+  ```
+  link to [`runFourSlashTest`][0]
+
+  [0]: <src/harness/fourslash.ts - function runFourSlashTest(>
+  ```
+
+  Will look at the file `src/harness/fourslash.ts` in microsoft/TypeScript to 
+  find the line of code `function runFourSlashTest` and provide a direct link 
+  in the wiki. You can audit them via the script `npm run lint`.
