NPM needs to be installed.
Open the project folder in the command line of your choice and run npm install.
Open the project with Visual Studio Code and build it.
Then, open the project where you want to use the TSLint rule and add "high-comment-quality": true to your rules dictionary.
Finally, add the path to the built project to your rulesDirectory array, e.g.:
"rulesDirectory": [
"/Users/<USER>/highCommentQualityRule/project"
]
