+## Rest demo
+
+This  demo shows interacting with the Github API via Invoke-WebRequest.
 
 rest.ps1:
-Invoke-RestMethod is used to get the json of a repo as a PowerShell object,
-the object is then manipulated and the "private" parameter is changed to 'false'.
-The object is converted back to json formating and Posted back to the repo API
-
-The benefit of PowerShell is shown at the end of the script with PS objects.
-Enabling users to get info on multiple repos and then sort that data as objects.
-
-curlDemo.txt:
-This shows the equavilent bash commmands to change the private status of a Github repo
+Invoke-WebRequest and ConvertFrom-Json are used to get the issues of a repo.
+The issues are processed as objects to find the most commented on issues.
