+# Open WebUI + Ollama (Self-Contained) on Linux
+
+This stack runs Open WebUI and Ollama in Docker with persistent storage, and starts automatically at boot via systemd.
+
+## 1) Install Docker and compose plugin
+
+Ubuntu/Debian example:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y docker.io docker-compose-plugin
+sudo systemctl enable --now docker
+```
+
+## 2) Copy this folder to your Linux host
+
+Example destination:
+
+```bash
+/opt/openwebui-ollama-src
+```
+
+## 3) Run installer
+
+```bash
+cd /opt/openwebui-ollama-src
+chmod +x install-linux.sh
+./install-linux.sh
+```
+
+What it does:
+- Copies `docker-compose.yml` to `/opt/openwebui-ollama`
+- Installs and enables `openwebui-ollama.service`
+- Starts the stack immediately
+
+## 4) Open WebUI
+
+Browse to:
+
+```text
+http://<linux-host-ip>:3000
+```
+
+## 5) Validate boot persistence
+
+```bash
+sudo systemctl status openwebui-ollama.service
+sudo reboot
+# after reboot
+sudo systemctl status openwebui-ollama.service
+docker ps
+```
+
+## Optional: Pull additional Ollama models
+
+```bash
+docker exec ollama ollama pull qwen2.5:7b
+docker exec ollama ollama pull mistral:7b
+```
