This project was developed using the yarn package manager. Find out how to install yarn for your operating system. After cloning this project, go into the root folder and run yarn install. Once that is done, run yarn global add gatsby-cli. This will add the gatsby-cli as a global executable. Run yarn global bin to see where it has been installed. If this location is not part of your PATH environment variable, add the pathname as to PATH as well. If gatsby has been installed successfully, running gatsby --version will show you the version of the installed executable.
Thereafter, develop using gatsby develop or yarn start. The webapp will be running on http://localhost:8000/.
