+A web client for ChatGPT, using OpenAI's API.
 
-## Quick start with docker
-```bash
-docker run -p 80:80 wongsaang/chatgpt-ui:latest
+## 📢Updates
+
+---
+
+Version 2 is a major update that separates the backend functionality as an independent project, hosted at [chatgpt-ui-server](https://github.com/WongSaang/chatgpt-ui-server). 
+
+If you still wish to use the old version, please visit the [v1 branch](https://github.com/WongSaang/chatgpt-ui/tree/v1).
+
+Version 2 introduces the following new features:
+
+- 😉 Separation of the frontend and backend, with the backend now using the Python-based Django framework.
+- 😘 User authentication, supporting multiple users.
+- 😀 Ability to store data in an external database (defaulting to Sqlite).
+- 😎 Session persistence, allowing the API to answer questions based on your context.
+
+
+## Quick start with Docker Compose

+### Run services
+
+Below is a docker-compose.yml template:
+
+```yaml
+version: '3'
+services:
+  client:
+    image: wongsaang/chatgpt-ui-client:latest
+    environment:
+      - SERVER_DOMAIN=http://backend:8000
+    depends_on:
+      - backend
+    volumes:
+      - backend_static:/app/static
+    ports:
+      - '80:80'
+    networks:
+      - chatgpt_ui_network
+  backend:
+    image: wongsaang/chatgpt-ui-server:latest
+    environment:
+      #      - DB_URL=postgres://postgres:postgrespw@localhost:49153/chatgpt # If this parameter is not set, the built-in Sqlite will be used by default. It should be noted that if you do not connect to an external database, the data will be lost after the container is destroyed.
+      - DJANGO_SUPERUSER_USERNAME=admin # default superuser name
+      - DJANGO_SUPERUSER_PASSWORD=password # default superuser password

+### After running
+
+After running the services, you can access the web client at http://localhost, and an admin panel at http://localhost/admin.
+
+Before you can start chatting, you need to log in to the admin panel to add an OpenAI API key. In the Settings model, add a record with the name "openai_api_key" and the value as your API key.
