+## Changes
+* [#90](https://github.com/cleverage/process-bundle/issues/90) Installation documentation: describe the Symfony Flex recipe ([symfony/recipes-contrib#2081](https://github.com/symfony/recipes-contrib/pull/2081)), which registers the bundle and creates `config/packages/clever_age_process.yaml` importing the `config/packages/process/` directory, and the manual setup without Flex.

-Remember to add the following line to `config/bundles.php` (not required if Symfony Flex is used):
+With [Symfony Flex](https://symfony.com/doc/current/setup/flex.html), the
+[recipe](https://github.com/symfony/recipes-contrib/tree/main/cleverage/process-bundle) registers the bundle and creates:
+- `config/packages/clever_age_process.yaml`: the [global configuration](#global-configuration), which imports the
+  `config/packages/process/` directory,
+- `config/packages/process/`: the directory of your processes, one file per process (see
+  [process definition](reference/01-process_definition.md)).
+
+Without Flex, add the following line to `config/bundles.php`:
 
 ```php
 CleverAge\ProcessBundle\CleverAgeProcessBundle::class => ['all' => true],
 ```
 
+Then create the `config/packages/process/` directory and the configuration that imports it:
+
+```yaml
+# config/packages/clever_age_process.yaml
+imports:
+    - { resource: process/ }
+
+clever_age_process:

 Some tasks and transformers use the Symfony serializer (`NormalizerTask`, `DenormalizerTask`, `SerializerTask`,
 `DeserializerTask`, the `normalize` and `denormalize` transformers) or validator (`ValidatorTask`) services. If they are
 not enabled, the container still compiles, and a process using one of these tasks or transformers fails with an explicit
