+## Parallel processing
+
+The `--parallel` option is available for speeding up the validation of CSV files by utilizing more CPU resources
+effectively.
+
+### Key Points
+
+- **Experimental Feature:** This feature is currently experimental and requires further debugging and testing. Although
+  it performs well in synthetic autotests and benchmarks. More practical use cases are needed to validate its stability.
+- **Use Case:** This option is beneficial if you are processing dozens of CSV files, with each file taking 1 second or
+  more to process.
+- **Default Behavior:** If you use `--parallel` without specifying a value, it defaults to using the maximum number of
+  available CPU cores.
+- **Thread Pool Size:** You can set a specific number of threads for the pool. For example, `--parallel=10` will set the
+  thread pool size to 10. It doesn't make much sense to specify more than the number of logical cores in your CPU.
+- **Disabling Parallelism:** Using `--parallel=1` disables parallel processing, which is the default setting if the
+  option is not specified.
+- **Implementation:** The feature relies on the `ext-parallel` PHP extension, which enables the creation of lightweight
+  threads rather than processes. This extension is already included in our Docker image. Ensure that you have
+  the `ext-parallel` extension installed if you are not using our Docker image. This extension is crucial for the
+  operation of the parallel processing feature. The application always runs in single-threaded mode if the extension is
+  not installed.
