+# play-scala-seed
+
+This is a seed project based on a giter8 template.
+
+To run the project, assuming you have sbt installed
+(it is installed for you on turing), cd into its top-level directory and
+run: 
+
+
+```sh
+sbt
+```
+
+Then, from the sbt prompt, to start it on port 1234
+
+```sh
+run 1234
+```
+
+If you are on a shared machine (eg, turing) you should
+choose a port number nobody else is using. On turing, 
+there is a script `my_tomcat_ports` that can give you
+some random port numbers to use.
+
+To stop the server, press Ctrl-d
+
+To exit the sbt prompt, press Ctrl-d again
+
+### Changes to the giter8 template
+
+I have made some changes to the 
+
+* **Added Hopper as a repository**  
+  The Scala Build Tool (sbt) knows how to fetch libraries for you.
+  I have added Artifactory on Hopper as a source of libraries.
+  
+* **Changed the Content-Security-Policy**  
+  Out-of-the-box, Play has strict security settings, including setting
+  the Content-Security-Policy header to 'self' which might prevent your
+  pages from loading other scripts. I've relaxed this.
+  
+* **Added Play JSON**  
+  I have added the library import for the JSON parsing library,
+  and a couple of examples
