+# Installation time settings
+## Network ports
+During installation, the installer tries to start a web server on port `0.0.0.0:9000`. If this port is already in use, the startup will fail. You can change the port that the installer will use:
+### Linux
+Start the installer using `SD_UI_BIND_PORT=1234 ./start.sh` (Replace 1234 with the port number you want to use). If you also want to limit the web server to only listen to `localhost`, you can use `SD_UI_BIND_PORT=1234 SD_UI_BIND_IP=127.0.0.1 ./start.sh`
+
+### Windows
+First, open a `cmd` window, in which you run the following commands (replace `X` by the drive letter of your installation drive):
+```
+cd /d X:\stable-diffusion-ui
+set SD_UI_BIND_PORT=1234
+"Start Stable Diffusion UI.cmd"
+```
+If you also want to limit the web server to only listen to `localhost`, you can use:
+```
+cd /d X:\stable-diffusion-ui
+set SD_UI_BIND_PORT=1234
+set SD_UI_BIND_IP=127.0.0.1
+"Start Stable Diffusion UI.cmd"
+```
+
+# Runtime settings
+The runtime settings are stored in the following files:
+* `scripts/config.json`
+* `scripts/config.bat` (Windows) 
+* `scripts/config.sh` (Linux)
+The `.bat` and `.sh` files contain settings required for the startup of the application. The `.json` file has settings needed at runtime.
