-## zPages
-
-> **Deprecation Notice**: zPages is scheduled for removal in a future version. See [Issue #5571](https://github.com/open-telemetry/opentelemetry-java/issues/5571) for details.
-
-OpenTelemetry Java zPages are a collection of dynamic HTML web pages embedded in your app that
-display stats and trace data. Learn more
-in [this blog post](https://medium.com/opentelemetry/zpages-in-opentelemetry-2b080a81eb47).
-
-### Register the zPages
-
-**Note:** The package `com.sun.net.httpserver` is required to use the default zPages setup. Please
-make sure your
-version of the JDK includes this package.
-
-To setup the zPages, register zPages with your `OpenTelemetrySdk` and
-call `startHttpServerAndRegisterAllPages(int port)` on your ZPageServer instance:
-
-```java
-public class MyMainClass {
-  public static void main(String[] args) throws Exception {
-    // Create a new ZPageServer
-    ZPageServer zpageServer = ZPageServer.create();
-    // Configure OpenTelemetrySdk with zPages
-    OpenTelemetry openTelemetry =
-        OpenTelemetrySdk.builder().setTracerProvider(zpageServer.buildSdkTracerProvider()).build();
-
-    // Start zPages server
-    zpageServer.startHttpServerAndRegisterAllPages(8080);
-    // ...Do work (this is just an example)
-    long count = 0;
-    while (true) {
-      Tracer tracer = openTelemetry.getTracer("demo");
-      Span span = tracer.spanBuilder("exampleSpan" + ++count).startSpan();
-      try (Scope scope = span.makeCurrent()) {
-        System.out.println("Inside a span...");
-        TimeUnit.SECONDS.sleep(2);
-      }
-      span.end();
-    }
-  }
-}
-```
-
-Note that `startHttpServerAndRegisterAllPages()` will create a new `HttpServer` and register the zPages
-with it. If you already have an existing or shared `HttpServer`, you can instead call
-`registerAllPagesToHttpServer(HttpServer server)`:
-
-```java
-public class MyMainClass {
-  public static void main(String[] args) throws Exception {
-    // ...configure OpenTelemetrySdk with zPages
-
-    // Start zPages server
-    HttpServer server = HttpServer.create(new InetSocketAddress(8000), 10);
-    zPageServer.registerAllPagesToHttpServer(server);
-    server.start();
-    // ... do work
-  }
-}
-```
-
-### Access the zPages
-
-#### View all available zPages on the `/` index page
-
-The index page `/` lists all available zPages with a link and description.
-
-#### View trace spans on the `/tracez` zPage
-
-The /tracez zPage displays information on running spans, sample span latencies, and sample error
-spans. The data is aggregated into a summary-level table:
-
-![tracez-table](img/tracez-table.png)
-
-You can click on each of the counts in the table cells to access the corresponding span
-details. For example, here are the details of the `ChildSpan` latency sample (row 1, col 4):
-
-![tracez-details](img/tracez-details.png)
-
-#### View and update the tracing configuration on the `/traceconfigz` zPage
-
-The /traceconfigz zPage displays information about the currently active tracing configuration and
-provides an interface for users to modify relevant parameters. Here is what the web page looks like:
