 ## Usage
 
+You can either use it as composer dependency or as docker command.

 ### Generate command
 
 1. Define schema file, see [tests/fixtures](tests/fixtures/) for examples.
 
 2. Generate POPO files, run:
-
-    ```sh
-    vendor/bin/popo generate -s <schema-path> \
-      -c [schema-config-filename] \
-      -o [output-path] \

+### Docker support
+
+With docker you can generate files without installing `POPO` as dependency in the project.
+
+```
+docker container run -it --rm  -v "$(pwd):/app/" -w/app oliwierptak/popo bin/popo
+```
+
+You can either run the command directly, or create an alias, e.g.:
+
+```
+alias docker-popo='docker container run -it --rm  -v "$(pwd):/app/" -w/app oliwierptak/popo bin/popo ${@}'
+```
+
+For example:
+
+```
+docker-popo generate -s tests/fixtures/popo.yml
+docker-popo report -s tests/fixtures/popo.yml
+```
