 After running
 
+Startup.cs
+
+```cs
+public void ConfigureServices(IServiceCollection services)
+{
+    ...
+
+    Configuration.ResolveVariables();
+
+    ...
+}
+```
+
+ResolveVariables will take any variable path and resolve it. It even works across .json files. As long as the data is stored inside the ConfigurationRoot, it is resolvable
+
+## Variable Identification
+
+In the ResolveVariables function you can declare what a variable is (default `{{variable}}`). 
+
+Example: 
+
+Startup.cs
+
 ```cs
-IConfigurationRoot configuration = ...
-configuration.ResolveVariables();
+public void ConfigureServices(IServiceCollection services)
+{
+    ...
+
+    Configuration.ResolveVariables("${", "}");
+
+    ...
+}
+```
+
+appsettitngs.json
+
+```json
+{
+    "General":
+    {
+        "HttpListenPort": "3000",
+        "HttpsListenPort": "3001",
+        "WebUrl": "https://localhost:${General.HttpsListenPort}"
+    },
+    "Pages":
+    {
+        "AuthorizeAddress": "${General.WebUrl}/api/beta/authorize",
+        "DashboardAddress": "${General.WebUrl}/dashboard"
+    }
+}
+```
+
+Now anything inside the `${variable}` is considered a variable.
+
+## Nested variables (variables inside variables)
+
+If the need arises you can also resolve variables within other variables
+
+Example: 
+
+Assuming `ASPNETCORE_ENVIRONMENT = Development`
+
+appsettings.json
+
+```json
+{
+    "App":
+    {
+        "Development": {
+            "ClientId": "FooId"
+        }
+    },
+    "Auth":
+    {
+        "ClientID": "${App.${ASPNETCORE_ENVIRONMENT}.ClientId}"
+    }
+}
+```
+
+Will become
+
+```json
+{
+    "App":
+    {
+        "Development": {
+            "ClientId": "FooId"
+        }
+    },
+    "Auth":
+    {
+        "ClientID": "${App.Development.ClientId}"
+    }
+}
 ```
 
-ResolveVariables will take any variable path and resolve it. It even works across .json files. As long as the data is stored inside the ConfigurationRoot, it is resolvable
+Which will resolve to 
+
+```json
+{
+    "App":
+    {
+        "Development": {
+            "ClientId": "FooId"
+        }
+    },
+    "Auth":
+    {
+        "ClientID": "FooId"
+    }
