 Building KasmVNC
 =================
 
+Building the KasmVNC Server using Docker
+----------------------------------------
+
+```bash
+git submodule init
+git submodule update --remote --merge
+sudo docker build -t kasmvnc:dev -f builder/dockerfile.ubuntu_jammy.dev .
+sudo docker run -it -v ./:/src -p 6901:6901  kasmvnc:dev
+```
+
+Now from inside the container.
+
+```bash
+# build frontend
+cd kasmweb
+npm install
+npm run build # <-- only run this on subsequent changes to front-end code
+cd ..
+# build dependencies
+sudo builder/scripts/build-webp
+sudo builder/scripts/build-build-libjpeg-turbo
+# Build KasmVNC
+builder/build.sh
+```
+
+Now run Xvnc and Xfce4 from inside the container
+
+```bash
+/src/xorg.build/bin/Xvnc -interface 0.0.0.0 -PublicIP 127.0.0.1 -disableBasicAuth -RectThreads 0 -Log *:stdout:100 -httpd /src/kasmweb/dist -sslOnly 0 -SecurityTypes None -websocketPort 6901  :1 &
