+If you want to customize the image by adding some packages, e.g. `lsphp80-pspell`, just extend it with a Dockerfile. 
 1. We can create a `custom` folder and a `custom/Dockerfile` file under the main project.

 ```
 FROM litespeedtech/openlitespeed:latest
-RUN apt-get update && apt-get install lsphp74-pspell -y
+RUN apt-get update && apt-get install lsphp80-pspell -y
 ```
 3. Add `build: ./custom` line under the "image: litespeedtech" of docker-composefile. So it will looks like this
