+
+The objective of ParaTest is to support parallel testing in PHPUnit. Provided you have well-written PHPUnit tests, you can drop `paratest` in your project and
+start using it with no additional bootstrap or configurations!
+
+Benefits:
+
+* Zero configuration. After the installation, run with `vendor/bin/paratest` to parallelize by TestCase or `vendor/bin/paratest --functional` to parallelize by Test. That's it!
+* Code Coverage report combining. Run your tests in N parallel processes and all the code coverage output will be combined into one report.
+
+# Installation
+
+To install with composer run the following command:
+
+    composer require --dev brianium/paratest
+    
+# Versions
+
+Only the latest version of PHPUnit is supported, and thus only the latest version of ParaTest is actively maintained.
+
+This is because of the following reasons:
+
+1. To reduce bugs, code duplication and incompatibilities with PHPUnit, from version 5 ParaTest heavily relies on PHPUnit `@internal` classes
+1. The fast pace both PHP and PHPUnit have taken recently adds too much maintenance burden, which we can only afford for the latest versions to stay up-to-date
+
+# Usage
+
+After installation, the binary can be found at `vendor/bin/paratest`. Run it
+with `--help` option to see a complete list of the available options.
+
+## Test token
+
+The `TEST_TOKEN` environment variable is guaranteed to have a value that is different
+from every other currently running test. This is useful to e.g. use a different database
+for each test:
+
+```php
+if (getenv('TEST_TOKEN') !== false) {  // Using ParaTest
+    $dbname = 'testdb_' . getenv('TEST_TOKEN');
+} else {
+    $dbname = 'testdb';
+}
+```
+
+A `UNIQUE_TEST_TOKEN` environment variable is also available and guaranteed to have a value that is unique both
+per run and per process.
+
+## Code coverage
+
+The cache is always warmed up by ParaTest before executing the test suite.
+
+### PCOV
+
+If you have installed `pcov` but need to enable it only while running tests, you have to pass thru the needed PHP binary
+option:
+
+```
+php -d pcov.enabled=1 vendor/bin/paratest --passthru-php="'-d' 'pcov.enabled=1'"
+```
+
+### xDebug
+
+If you have `xDebug` installed, activating it by the environment variable is enough to have it running even in the subprocesses:
+
+```
+XDEBUG_MODE=coverage vendor/bin/paratest
+```
+
+## Initial setup for all tests
+
+Because ParaTest runs multiple processes in parallel, each with their own instance of the PHP interpreter,
+techniques used to perform an initialization step exactly once for each test work different from PHPUnit.
+The following pattern will not work as expected - run the initialization exactly once - and instead run the
+initialization once per process:
+
+```php
+private static bool $initialized = false;
+
+public function setUp(): void
+{
+    if (! self::$initialized) {
+         self::initialize();
+         self::$initialized = true;
+    }
+}
+```
+
+This is because static variables persist during the execution of a single process.
+In parallel testing each process has a separate instance of `$initialized`.
+You can use the following pattern to ensure your initialization runs exactly once for the entire test invocation:
+
+```php
+static bool $initialized = false;
+
+public function setUp(): void
+{
+    if (! self::$initialized) {
+        // We utilize the filesystem as shared mutable state to coordinate between processes
+        touch('/tmp/test-initialization-lock-file');
+        $lockFile = fopen('/tmp/test-initialization-lock-file', 'r');
+
+        // Attempt to get an exclusive lock - first process wins
+        if (flock($lockFile, LOCK_EX | LOCK_NB)) {
+            // Since we are the single process that has an exclusive lock, we run the initialization
+            self::initialize();
+        } else {
+            // If no exclusive lock is available, block until the first process is done with initialization
+            flock($lockFile, LOCK_SH);
+        }
+
+        self::$initialized = true;
+    }
+}
+```
+
+## Troubleshooting
+
+If you run into problems with `paratest`, try to get more information about the issue by enabling debug output via
+`--verbose --debug`.
+
+When a sub-process fails, the originating command is given in the output and can then be copy-pasted in the terminal
+to be run and debugged. All internal commands run with `--printer [...]\NullPhpunitPrinter` which silence the original
+PHPUnit output: during a debugging run remove that option to restore the output and see what PHPUnit is doing.
+
+## Windows
+
+Windows users be sure to use the appropriate batch files.
+
+An example being:
+
+`vendor\bin\paratest.bat ...`
+
+ParaTest assumes [PSR-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md) for loading tests.
+
+For convenience, ParaTest for Windows uses 79 columns mode to prevent blank lines in the standard
+80x25 windows console.
+
+## Caveats
+
+1. Constants, static methods, static variables and everything exposed by test classes consumed by other test classes
+(including Reflection) are not supported. This is due to a limitation of the current implementation of `WrapperRunner`
+and how PHPUnit searches for classes. The fix is to put shared code into classes which are not tests _themselves_.
+
+## Integration with PHPStorm
+
+ParaTest provides a dedicated binary to work with PHPStorm; follow these steps to have ParaTest working within it:
+
+1. Be sure you have PHPUnit already configured in PHPStorm: https://www.jetbrains.com/help/phpstorm/using-phpunit-framework.html#php_test_frameworks_phpunit_integrate
+2. Go to `Run` -> `Edit configurations...`
+3. Select `Add new Configuration`, select the `PHPUnit` type and name it `ParaTest`
+4. In the `Command Line` -> `Interpreter options` add `./vendor/bin/paratest_for_phpstorm`
+5. Any additional ParaTest options you want to pass to ParaTest should go within the `Test runner` -> `Test runner options` section
+
+You should now have a `ParaTest` run within your configurations list.
+It should natively work with the `Rerun failed tests` and `Toggle auto-test` buttons of the `Run` overlay.
+
+### Run with Coverage
+
+Coverage with one of the [available coverage engines](#code-coverage) must already be [configured in PHPStorm](https://www.jetbrains.com/help/phpstorm/code-coverage.html) 
+and working when running tests sequentially in order for the helper binary to correctly handle code coverage
+
