+The argo-status-pages application provides a simple way to configure connection and appearence parameters through the `config.json` file. For example:
+
+```json
+{
+  "services": {
+    "Service_A": {
+      "fullname": "Service A",
+      "category": "Category A"
+    },
+    "Service_B": {
+      "fullname": "Service B",
+      "category": "Category A"
+    }
+  },
+  "service_categories": {
+    "Category A": ["Service_A", "Service_B"]
+  },
+  "ngi_categories": {
+    "Service_A": "Service_A",
+    "Service_B": "Service_B"
+  },
+  "api": {
+    "endpoint": "api.devel.example.com",
+    "reportName": "CORE"
+  },
+  "title": "Test Status Page",
+  "copyright": "Copyright 2022 - All rights reserved",
+  "theme": {
+    "header-gradient-color-start": "#05cae7",
+    "header-gradient-color-end": "#000",
+    "footer-gradient-color-start": "#05cae7",
+    "footer-gradient-color-end": "#000",
+    "footer-copyright-text-color": "#fff"
+  }
+}
+```
+
+The `public` directory of the project may host specific assets such as the `favicon.ico`, the `logo.svg` or the `footer_logo.svg`.
+In addition to the image assets, a `.env` file may exist on the `public` directory that will define the `REACT_APP_TITLE`
+variable for the argo-status-pages title.
