+
+## Configure Grafana Alloy
+
+1. Open the `config.alloy` configuration file, which is located in the folder alongside the `alloy-installer-windows-amd64.exe` file.
+1. Set the `__path__` in the `local.file_match "ApiGateway"` > `path_targets` section to the path of the `Logs` folder specified in the `appSettings.json` file during installation of the API Gateway Service, e.g. `"C:/ProgramData/Cortex/API Gateway Service/Logs/**/ServiceFabricHttpEventLog-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]{_[0-9][0-9][0-9],}.json"`.
+1. Set the Grafana Loki `url` in the `loki.write "default"` > `endpoint` section, which can be found at the end of the file, with the url value noted down during the [Setup Grafana Loki][] steps.
+
+   A correct URL should be similar to `https://239948:eyJrIjoiaWVjNzE4MmVjOThkNTgxMMQ5MzIyZjdlMjAyYWY4NWJjO1I1OTc4NSIsIm4iOiJUZXN0S2V5IiwiaWQiOjY4Nzk0MX0=@logs-prod-008.grafana.net/api/prom/push`.
+1. Delete the line containing `bearer_token_file` in the `loki.write "default"` > `endpoint` section, which can be found at the end of the file.
+1. Save the file.
+
+### Re-Start the Grafana Alloy Service
+
+1. Open `services.msc`.
+1. Locate the `Alloy` service.
+1. Right click on the service name and select `Restart`. If the service is not already running, select `Start`.

+
+## Install Grafana Alloy
+
+1. Download the [Grafana Alloy 1.10.0][] archive.
+1. Extract content of the downloaded archive to a suitable location, e.g. `C:\Program Data\Cortex\Observability\Grafana Alloy`.
+1. Download the [Grafana Alloy.zip][] archive and extract its contents alongside the previously extracted Grafana Alloy `alloy-installer-windows-amd64.exe`.
+This archive contains the `config.alloy` configuration file and PowerShell scripts to install Grafana Alloy as a Windows service.
+1. Run Windows PowerShell as Administrator
+1. Change the location to where all the files were extracted to in step 2, e.g. `cd "C:\Program Data\Cortex\Observability\Grafana Alloy"`.
+1. Execute the `.\Install-Alloy.ps1` command to install the downloaded `alloy-installer-windows-amd64.exe` as a service.
+1. When prompted, enter the credentials that the Grafana Alloy Service should run as.
+1. When prompted to enter the bearer token, leave it blank and press Enter.
