After you git clone the repo, run npm install to install all relevant packages.
After you run the npm install, you can run npm start to run the site locally.
Anytime you edit a file, the correct process will do what it needs to do and then restart.
If the website isn't working, then you might not have created the env.njk file. You'll need to create a file called env.njk in the
src/views folder, and then you'll want to copy {% set baseUrl = "http://localhost:3000/" %} into that file.
