### Accessing the Database
After installation, you can use phpMyAdmin to access the database by visiting `http://127.0.0.1:8080` or `https://127.0.0.1:8443`. The default username is `root`, and the password is the same as the one you supplied in the `.env` file.
+## Customization
+If you want to customize the image by adding some packages, e.g. `lsphp74-pspell`, just extend it with a Dockerfile.
+1. We can create a `custom` folder and a `custom/Dockerfile` file under the main project.
+2. Add the following example code to `Dockerfile` under the custom folder
+```
+FROM litespeedtech/openlitespeed:latest
+RUN apt-get update && apt-get install lsphp74-pspell
+```
+3. Add `build: ./custom` line under the "image: litespeedtech" of docker-composefile. So it will looks like this
+```
+ litespeed:
+ image: litespeedtech/openlitespeed:${OLS_VERSION}-${PHP_VERSION}
+ build: ./custom
+```
+4. Build and start it with command:
+```
+docker-compose up --build
+```
+
