0:06 = Hello, in this video we will see how to create apps on JuliaBox
0:23 = Click on the "Launch" button to start Jupyter
0:37 = Now we go back to the dashboard and open up the "My Apps" tool
0:42 = The default values describe a built-in example app that you can run. Just hit "Deploy"
1:03 = Now you should see the app on the dashboard. Click on the "Short Link" to connect to the app. This link can also be shared with o
ther users.
1:13 = Lets wait for the app to start up. This app accepts some code on the left box and runs it when you click the button. The results
are on the right.
1:34 = Now lets see the julia code for this app
1:46 = First we copy the file from the default location to our home so that Jupyter can see it.
