 ### Testing Type Definition Correctness
 
-This project uses [tsd](https://github.com/SamVerschueren/tsd) to test the built definition files (`*.d.ts`).
-
 Type tests are located in the `test-dts` directory. To run the dts tests, run `nr test-dts`. Note that the type test requires all relevant `*.d.ts` files to be built first (and the script does it for you). Once the `d.ts` files are built and up-to-date, the tests can be re-run by simply running `nr test-dts`.
