+## Configuration
+
+After installing the XhprofTrace library and the XHProf extension, you need to configure them to ensure they work correctly in your environment.
+
+### XhprofTrace Library
+
+The XhprofTrace library requires minimal configuration. However, you should ensure that the `xhprof.output_dir` is set in your `php.ini` file. This directory is where the XHProf profiling data will be saved. For example:
+
+```ini
+xhprof.output_dir = "/path/to/your/directory"
+```
+
+### XHProf Extension
+
+To adjust the profiling granularity and other settings of the XHProf extension, you can modify the following settings in your `php.ini` file:
+## Advanced Examples
+
+The XhprofTrace library offers flexibility to customize your profiling needs. Below are some advanced examples showcasing its capabilities.
+
+### Filtering Profiling Data
+
+You can filter the profiling data to focus on specific parts of your application. This is useful for isolating performance issues:
+
+```php
+use MarjovanLier\XhprofTrace\Trace;
+
+Trace::enableXhprof([
+    'ignored_functions' => ['time_nanosleep', 'str_repeat']
+]);
+
+// Your application code here...
+
+Trace::disableXhprof();
+```
+
+In this example, `ignored_functions` is used to exclude specific functions from the profiling data.
+
+### Integrating with Other Tools
+
+XhprofTrace can be integrated with other tools for more comprehensive analysis. For example, integrating with a visualization tool:
+
+```php
+use MarjovanLier\XhprofTrace\Trace;
+
+Trace::enableXhprof();
+
+// Your application code here...
+
+Trace::disableXhprof();
+
+// Generate a URL to view the profiling report using an external tool
+$url = Trace::generateReportURL('https://external-tool.com/view?data=', '/path/to/report/file');
+
+echo "View the profiling report: " . $url;
+```
+
+This example demonstrates how to generate a URL for viewing the profiling report with an external visualization tool.
+
+### Customizing the Report Output
+
+You can customize the output of the profiling report to include additional information or format it differently:
+
+```php
+use MarjovanLier\XhprofTrace\Trace;
+
+Trace::enableXhprof();
+
+// Your application code here...
+
+Trace::disableXhprof();
+
+// Customize the report output
+Trace::displayReportCLI([
+    'format' => 'json',
+    'include_memory_usage' => true
+]);
+```
+
+This example shows how to customize the report output format and include memory usage information.
+
+- `xhprof.sampling_interval`: Determines the sampling interval in microseconds. A lower value increases the granularity of the profiling data but may impact performance. The default value is `100000` (100ms).
+

+## Troubleshooting & FAQ
+
+### Common Issues
+
+#### Installation Problems
+- **Issue**: XHProf extension not found after installation.
+  - **Solution**: Ensure the `extension=xhprof.so` (Linux/macOS) or `extension=php_xhprof.dll` (Windows) line is correctly added to your `php.ini`. Restart your web server or PHP-FPM service afterwards.
+
+#### Configuration Errors
+- **Issue**: Profiling data not being generated.
+  - **Solution**: Check the `xhprof.output_dir` setting in your `php.ini` to ensure it points to a writable directory.
+
+#### Runtime Errors
+- **Issue**: Profiler causes unexpected application behavior.
+  - **Solution**: Disable the profiler to isolate the issue. If the problem persists, it may not be related to XhprofTrace.
+
+### FAQ
+
+- **How do I interpret profiling data?**
+  Profiling data provides insights into function call counts, CPU time, and memory usage. Use visualization tools like XHProf UI for a more intuitive analysis.
+
+- **How can I improve profiling performance?**
+  Increase the `xhprof.sampling_interval` to reduce the amount of data collected. Note that this will also decrease the granularity of the profiling data.
+
+- **How can I contribute to the XhprofTrace library?**
+  Contributions are welcome! Check the repository's issues for open tasks or create a pull request with your improvements.
