+# Notes
+
+If you want to use bind mounts instead of Docker volumes, you can do so.
+
+However, the container will report back permission errors for the path `/var/www/html/images/_assets/`. Something like:
+
+````
+chevereto          | Exception thrown in /var/www/html/app/src/Legacy/Classes/LocalStorage.php:45
+chevereto          | 
+chevereto          | # Message [Code #600]
+chevereto          | Path /var/www/html/images/_assets/ is not writable
+````
+
+Those can only be solved by spawning a shell into the Docker container and fixing the permissions as follows:
+
+````
+# spawning shell into the docker container
+docker exec -it chevereto bash
+
+# fixing permissions to www-data
+mkdir -p /var/www/html/images/_assets
+chown -R www-data:www-data /var/www/html/images/*
+chmod -R 777 /var/www/html/images/*
+````
+No container restart necessary. The web application should now work flawlessly.
+
+Note: The permission issues only occur if bind mounts are used over Docker named volumes.
