+## Notes
+
+Use [newtonsoft-json](https://www.nuget.org/packages/Newtonsoft.Json/) package to parse JSON API response. To download from NuGet, You can do this a couple of ways.
+
+**Via the "Solution Explorer"**
+
+    Simply right-click the "References" folder and select "Manage NuGet Packages..."
+    Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
+    Then in the search bar in the upper right type "json.net"
+    Click "Install" and you're done.
+
+**Via the "Package Manager Console"**
+
+    Open the console. "View" > "Other Windows" > "Package Manager Console"
+    Then type the following:
+
+    Install-Package Newtonsoft.Json
+
+For more info on how to use the "Package Manager Console" check out the [nuget docs](https://docs.microsoft.com/fr-fr/nuget/tools/package-manager-console).
+
+### Patches
+
+Anybody can contribute to development. If you are contributing a source code change, use a merge request of a Git branch.
