-# Apollo Tracing
-
-_Apollo Tracing_ is a [performance tracing specification](https://github.com/apollographql/apollo-tracing) for GraphQL servers. It works by returning tracing information about the current request alongside the computed data. While it is not part of the GraphQL specification itself, there is a common agreement in the GraphQL community that all GraphQL servers should support it.
-
-**Example**
-
-```graphql
-{
-  book(id: 1) {
-    name
-    author
-  }
-}
-```
-
-The above request would result in the below response if _Apollo Tracing_ is enabled.
-
-```json
-{
-  "data": {
-    "book": {
-      "name": "C# in Depth",
-      "author": "Jon Skeet"
-    }
-  },
-  "extensions": {
-    "tracing": {
-      "version": 1,
-      "startTime": "2021-09-25T15:31:41.6515774Z",

-            "path": ["book"],
-            "parentType": "Query",

-## Enabling Apollo Tracing
-
-_Apollo Tracing_ needs to be explicitly enabled by calling `AddApolloTracing` on the `IRequestExecutorBuilder`.
-
-```csharp
-builder.Services
-    .AddGraphQLServer()
-    .AddApolloTracing();
-```
-
-Further, we can specify a `TracingPreference`. Per default, it is `TracingPreference.OnDemand`.
-
-```csharp
-builder.Services
-    .AddGraphQLServer()
-    .AddApolloTracing(TracingPreference.Always);
-```
-
-There are three possible options for the `TracingPreference`.
-
-| Option     | Description                                                                                  |
-| ---------- | -------------------------------------------------------------------------------------------- |
-| `Never`    | _Apollo Tracing_ is disabled. Useful if we want to conditionally disable _Apollo Tracing_.   |
-| `OnDemand` | _Apollo Tracing_ only traces requests if a specific header is passed with the query request. |
-| `Always`   | _Apollo Tracing_ is always enabled, and all query requests are traced automatically.         |
-
-## On Demand
-
-When _Apollo Tracing_ is added using the `TracingPreference.OnDemand`, we are required to pass one of the following HTTP headers with our query request in order to enable tracing for this specific request.
-
-- `GraphQL-Tracing=1`
-- `X-Apollo-Tracing=1`
-
-When using `curl` this could look like the following.
-
-```bash
-curl -X POST -H 'GraphQL-Tracing: 1' -H 'Content-Type: application/json' \
-    -d '{"query":"{\n  book(id: 1) {\n    name\n    author\n  }\n}\n"}' \
-    'http://localhost:5000/graphql'
-```
