Run the following lines in a terminal window and type
git clone https://github.com/botfront/botfront-starter cd botfront-starter docker-compose up
First, it's going to download all the Docker images required (it's going to take a while, be patient). Then it's going to start all the services.
You can safely ignore the errors in the logs: we just need to setup Botfront and it's all going to be fixed.
Open http://localhost:8888 and follow the instructions. (If it doesn't work just wait a few more seconds for the service to be ready)
