+# Pixel Server
+
+This site is intended as a backing server to serve pixels being loaded on a web page. Note that the limit of data retrieved here is merely:
+
+> a pixel with query string `x` was requested
+
+No PII data is recorded.
+
+## Prerequisites
+* This project was built, tested, and peformance checked using `.NET Core 2.1`.
+* It is intended (and has been tested) for deployment to an `Azure AppService`
+* The backing data store is `Application Insights`, so you will need to create one prior to deployment.
+
+## Usage
+To add a tracking pixel, simply embed an image of the following form.
+
+```
+Markdown:
+
+
+RST:
+.. image:: https://.azurewebsites.net/api/impressions?path=
+
+Img URL:
+
+```
+
+## Deployment and Setup
+
+This site is currently configured to leverage `Application Insights` as a connected service. With the code that is currently checked in, the order to deploy your own version of this site is as follows:
+
+* Deploy site in `release` configuration to your AppService
+* Enable Application Insights on your AppService
+
+## Enabling Application Insights on your AppService
+
+First, install the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest). Use the `az login` command to sign in with the appropriate email to access your azure subscriptions. After that, ensure you've created an `Application Insights` where it is visible to your target AppService.
+
+Then, leverage the following az commands:
+
+```
+#retrieve the InstrumentationKey for your previously created appinsights
+$key = az resource show -g -n --resource-type "Microsoft.Insights/components" --query properties.InstrumentationKey
+
+#set the application insight for web app
+az webapp config appsettings set -g -n --settings "APPINSIGHTS_INSTRUMENTATIONKEY = $key"
+```
+
+Or, if you the above is too much trouble. Go through the UI.
+
