 of Pimcore, so that you can leverage the full functionality.
 
 You can either use this image directly by mounting Pimcore into the container, or as a template for your customized 
-
 ready-to-deploy images. As a starting point please see [example docker-compose configuration](https://github.com/pimcore/skeleton/blob/HEAD/docker-compose.yaml).

+## Image flavors
+We're providing 3 different image flavors: 
+- PHP image for FPM and CLI (e.g. `php8.1-latest`)
+- PHP debug image based on PHP image above, including preconfigured Xdebug for FPM and CLI (e.g. `php8.1-debug-latest`)
+- Supervisord image based on PHP image above, for cron & queue processing  (e.g. `php8.1-supervisord-latest`)
+
+## Versioning
+Our images are versioned using a version-suffix staring with `-v` following SemVer.   
+With that we're able to allow smooth upgrades, breaking changes are only delivered with major versions.  
+Additionally we're offering 2 special tag suffixes: 
+- `-latest` always points to the latest available tag (recommended for local development)
+- `-dev` always points to the work in progress
+
+We're also offering special tags for specific PHP versions, e.g. `php8.1.11-v1.0`. 
+
+## Examples 
+
+### PHP images
+```text
+php8.1-latest # always use the latest PHP 8.1 image
+php8.1-v1 # always point to the latest minor version of v1
+php8.1-v1.0 # pin to specific image version, always using the latest bugfixes from PHP 8.1
+php8.1.11-v1.0 # pin to a specific PHP version & image version 
+php8.1-dev # development image (build from the default branch) 
+```
+
+### PHP Debug images
+Same as PHP images, but using `-debug` after the PHP version:
+```text
+php8.1-debug-latest
+php8.1-debug-v1
+...
+```
+
+### Supervisord
+Same as PHP images, but using `-supervisor` after the PHP version:
+```text
+php8.1-supervisor-latest
+php8.1-supervisor-v1
+...
+```
