+# Template project for Vefaas
+
+This is a template project for Vefaas. You can use it as a starting point for your own project.
+
+We implement an minimal agent to report weather in terms of the given city.
+
+## Structure
+
+| File | Illustration |
+| - | - |
+| `src/app.py` | The entrypoint of VeFaaS server. |
+| `src/run.sh` | The launch script of VeFaaS server. |
+| `src/requirements.txt` | Dependencies of your project. `VeADK`, `FastAPI`, and `uvicorn` must be included. |
+| `src/config.py` | The agent and memory definitions. **You may edit this file.** |
+| `config.yaml.example` | Envs for your project (e.g., `api_key`, `token`, ...). **You may edit this file.** |
+| `deploy.py` | Local script for deployment. |
+
+You must export your agent and short-term memory in `src/config.py`.
+
+## Deploy
+
+We recommand you deploy this project by the `cloud` module of VeADK.
+
+```bash
+python deploy.py
+```
+
+You may see output like this:
+
+```bash
+Successfully deployed on:
+
+https://....volceapi.com
+Message ID: ...
+Response from ...: The weather in Beijing is sunny, with a temperature of 25°C.
+App ID: ...
+```
