+# How to setup
+Setting up is quite easy. I both cases I would suggest docker
+
+## Production Environment
+
+* fetch certificate for frontend and backend 
+  certbot certonly -d frontend.domain.de -d backend.domain.de --standalone
+* Setup proxy
+  Apache2:
+    <IfModule mod_ssl.c>
+    <VirtualHost *:443>
+      ServerName frontend.domain.de
+
+      SSLEngine on
+      SSLCertificateFile /etc/letsencrypt/live/frontend.domain.de/fullchain.pem
+      SSLCertificateKeyFile /etc/letsencrypt/live/frontend.domain.de/privkey.pem
+      Include /etc/letsencrypt/options-ssl-apache.conf
+
+      #-# Request header rules
+      RequestHeader set X-Forwarded-Proto "https"
+
+      ProxyPreserveHost On
+      ProxyRequests Off
+
+      ProxyPass / http://localhost:8181/
+      ProxyPassReverse / http://localhost:8181/ timeout=120
+
+      LogLevel warn
+      ErrorLog ${APACHE_LOG_DIR}/frontend.domain.de.error.log
+
+    </VirtualHost>
+    <VirtualHost *:443>
+      ServerName backend.domain.de
+      
+      SSLEngine on
+      SSLCertificateFile /etc/letsencrypt/live/bamort.trokan.de/fullchain.pem
+      SSLCertificateKeyFile /etc/letsencrypt/live/bamort.trokan.de/privkey.pem
+      Include /etc/letsencrypt/options-ssl-apache.conf

+      ProxyPreserveHost On
+      ProxyRequests Off
+
+      ProxyPass / http://localhost:8182/
+      ProxyPassReverse / http://localhost:8182/ timeout=120
+
+      LogLevel warn
+      ErrorLog ${APACHE_LOG_DIR}/backend.domain.de.error.log
+      TransferLog ${APACHE_LOG_DIR}/backend.domain.de.transfer.log
+      CustomLog ${APACHE_LOG_DIR}/backend.domain.de.access.log combined
+    </VirtualHost>
+    </IfModule>
+
+* Set URLS  to configure frontend and backend
+  edit ./docker/.env
+    #- Environment variables for Bamort production environment
+
+    #- API Configuration
+    API_URL=https://backend.domain.de
+    VITE_API_URL=https://backend.domain.de
+
+    #- Database Configuration Backend
+    DATABASE_TYPE=mysql
+    #DATABASE_URL=bamort:your_secure_user_password@tcp(mariadb:3306)/bamort?charset=utf8mb4&parseTime=True&loc=Local
+
+    #- MariaDB Configuration 
+    MARIADB_ROOT_PASSWORD=your_secure_root_password
+    MARIADB_PASSWORD=your_secure_user_password
+    MARIADB_DATABASE=bamort
+    MARIADB_USER=bamort
+
+    API_PORT=8180
+    BASE_URL=https://frontend.domain.de
+    TEMPLATES_DIR=./templates
+    EXPORT_TEMP_DIR=./export_temp
+  
+  !!! Do not configure DATABASE_URL for production in .env !!!
+
+* edit ./frontend/src/utils/api.js because the env variable does not work reliably
+    const API = axios.create({
+      baseURL: import.meta.env.VITE_API_URL || 'https://backend.domain.de', // Use env variable with fallback
+    })
+
+* edit ./docker/docker-compose.yml
+    Set VITE_API_URL and VITE_BASE_URL to https://backend.domain.de and https://frontend.domain.de
+
+* run ./docker/start-prd.sh
+* test https://backend.domain.de/api/public/version
+  should responde like this: {"version":"0.1.30","gitCommit":"unknown"}
+
+
+## Development Environment
+* Edit ./docker/.env
+  set 
+    API_URL=http://localhost:8180
+    VITE_API_URL=http://localhost:8180
+    API_PORT=8180
+    BASE_URL=http://localhost:5173
+
+* run ./docker/start-dev.sh
+
+Frontend is not reachable at http://localhost:5173 and backend at http://localhost:8180.
+Both containers are reacting on code changes and reload or rebuild automatically
+Database is automatically created with env variables in MARIADB_* set your DATABASE_URL accordingly
+Database is filled at first creation with values from ./docker/initdb/*.sql
