I have developed this theme as a personal project

You need to have npm and Angular CLI installed in your pc. Npm is aviable with NodeJS in here. After you install npm, install Angular CLI by typping the following command in your terminal

npm install -g @angular/cli

Just clone the repo and excecute the following command inside the folder proyect

npm install

Now just run

npm start

Wait to compile and go to http:https://localhost:4200 after compile finish

thsnks.
