+### How to run this image
+- currently this image must be build locally.(in future can be pulled from docker hub)
+- create folder to mount inside docker container
+    - `mkdir -p ./data/mariadb ./data/app/config ./data/app/saved_qrcode`
+- Run and build this image as host machine user
+    - `PUID="$(id -u)" PGID="$(id -g)" docker-compose up --build -d`
+- Run and build this image as specific user
+    - `PUID="1000" PGID="1000" docker-compose up --build -d`
+- Run app installation <IP>:8080/install
+    - Provide Database credentials
+- Default login: <IP>:8080
+    - user: superadmin
+    - password: superadmin
+
+### Roadmap
+- Make install process run via docker-compose.
+    - Work is partially done. docker-entrypoint.sh is created.(currently disabled due to next steps are pending)
+    - qrcode/install/database.php should be adjusted to create database without form submission.
+- Make it possible to set PUID and GUID, from environment variable in docker-compose.yml .
+- Reduce image size by removing unnecessary dependencies.
+- Automate Build image and push to docker hub.
+- Audit security flaws and fix it if needed.
+
+### some debug commands
+- `docker-compose logs`
+- `PUID="$(id -u)" PGID="$(id -g)" docker-compose config`
+- `ps -aef | grep apache2`
