Let's get started by cloning a repository that has built in errors.

Open that repository with VS Code and then install the packages.

npm install

Running Kropply

Open mergesort.test.ts. All you need to do now is to save it.


Wait a bit for suggestions to generate. In the background, Kropply is running Jest to capture the errors.
On the left hand side panel you should see the number of suggestions on top of the Kropply logo.
