+### registerTsProject
+
+▸ `Const` **registerTsProject**(`path`, `configFilename?`): `any`
+
+Optionally, if ts-node and tsconfig-paths are available in the current workspace, apply the require
+register hooks so that .ts files can be used for writing workspace lint rules.
+
+If ts-node and tsconfig-paths are not available, the user can still provide an index.js file in
+tools/eslint-rules and write their rules in JavaScript and the fundamentals will still work (but
+workspace path mapping will not, for example).
+
+#### Parameters
+
+| Name             | Type     | Default value     |
+| :--------------- | :------- | :---------------- |
+| `path`           | `string` | `undefined`       |
+| `configFilename` | `string` | `'tsconfig.json'` |
+
+#### Returns
+
+`any`
