 You can quickly scaffold a new Practice Exercise by running the `bin/add-practice-exercise` script ([source](https://github.com/exercism/generic-track/blob/main/bin/add-practice-exercise)) from the track's root directory:
 
 ```shell

 As an example, some tracks do not use classes but only work with functions.
 If your track usually works with objects though, you should adapt the implementation to what best fits your track.
 
+#### Add example implementation
+
+To ensure that it is possible to write code that passes the tests, an example implementation needs to be added.
+
+```exercism/note
+The code does _not_ have to be idiomatic, it only has to pass the tests.
+```
+
+You can verify the example implementation passes all the tests by running the `bin/verify-exercises` script ([source](https://github.com/exercism/generic-track/blob/main/bin/verify-exercises)) from the track's root directory:
+
+```shell
+bin/verify-exercises <exercise-slug>
+```
+
+Use the output to verify that the example implementation passes all the tests.
+
+```exercism/note
+If you're working on a track repo without this file, feel free to copy them into your repo using the above source link.
+```
+
+```exercism/advanced
+Under the hood, the `bin/verify-exercises` script does several things:
+
+- Copy the exercise to a temporary directory
+- Overwrite the stub file(s) with the example implementation file(s)
+- If the test file has skipped tests, they will be "unskipped"
+- Run the tests
+```
+
+### Lint exercise
+
+The final step is to run [the linter](/docs/building/configlet/lint) to check if the track's (configuration) files are properly structured - both syntactically and semantically.
+
+First, make sure you have the latest version of [`configlet`](/docs/building/configlet/) by running:
+
+```shell
+bin/fetch-configlet
+```
+
+The run [the linter](/docs/building/configlet/lint) by running:
+
+```shell
+bin/configlet lint
+```
+
+Use the output to verify that all is well.
