 ## Changes
+* [#320](https://github.com/cleverage/process-bundle/issues/320) README: add an installation section (`composer require`, bundle registration without Symfony Flex), linking to the quick start.
 * [#319](https://github.com/cleverage/process-bundle/issues/319) Composer: require PHP `^8.2` instead of `>=8.2` (PHP 9 is no longer accepted before being tested), remove the authorization of the `symfony/flex` plugin, which is not required (the CI installs it globally).
 * [#318](https://github.com/cleverage/process-bundle/issues/318) `CommandRunnerTask`, `ProcessLauncherTask` and `SubprocessInstance` receive the project directory, the path of the console and the environment (`%kernel.project_dir%`, `%kernel.environment%`) instead of the kernel: passing a `KernelInterface` is deprecated, the arguments will only accept strings in v6.0. `SubprocessInstance` writes the JSON buffer of `ProcessLauncherTask` (`json_buffering`) in the system temporary directory instead of `var/` of the project (which may be read-only), no longer creates the unused `<log dir>/process` directory, and omits `--env` when no environment is given (default environment of the console). Update documentation, add tests.
 * [#317](https://github.com/cleverage/process-bundle/issues/317) The bundle throws exceptions implementing `ProcessExceptionInterface` instead of raw SPL exceptions (124 `throw`): new `Exception\UnexpectedValueException`, `RuntimeException`, `InvalidArgumentException` and `LogicException`, extending the SPL exceptions thrown before (same messages, the existing `catch` keep working). All the errors of the bundle can be caught with `ProcessExceptionInterface`, except the exceptions of the Symfony components. Update documentation, add tests.
