 ### Optional: Slim down image using [Slim(toolkit)](https://github.com/slimtoolkit/slim)
 
 ```bash
-slim build --new-expose=3000 --http-probe-ports=3000  --include-path /usr/local --mount ./example-models:/example-models:z --env MOJO_CONFIG=/example-models/example-docker.conf idscorpuslinguistics/derekovecs
+slim build --include-path /usr/local/share/perl5 --mount ./example-models:/example-models:z --env MOJO_CONFIG=/example-models/example-docker.conf idscorpuslinguistics/derekovecs
 ```
 
 Will build an image `ids-kl/derekovecs.slim` reduced to ~25% of the original size.
