Step by step to install Scala + Play Framework in Ubuntu 14.04 with Activator.
Install Scala
sudo apt-get remove scala-library scala
wget http://www.scala-lang.org/files/archive/scala-2.11.6.deb
sudo dpkg -i scala-2.11.6.deb
sudo apt-get update
sudo apt-get install scala
You will need the user_id from the user. This is difficult to discover at Instagram but easy from this site http://jelled.com/instagram/lookup-user-id
I used http://jelled.com/instagram/access-token for the next few steps
You will also need an access token which ends up being difficult to obtain. Log into the account and go to their Developer Page.
