-docker run \
-  --name memos \
-  --publish 5230:5230 \
-  --volume ~/.memos/:/var/opt/memos \
-  neosmemo/memos:latest \

+If the `~/.memos/` does not have a `memos_prod.db` file, then memos will auto generate it. Memos will be running at [http://localhost:5230](http://localhost:5230).
 
-⚠️ Please DO NOT use `dev` tag of docker image if you have no experience.
+### Docker Compose
 
-## 🏗 Development
+Example Compose YAML file: [`docker-compose.yaml`](./docker-compose.yaml).
 
-Memos is built with a curated tech stack. It is optimized for developer experience and is very easy to start working on the code:
+If you want to upgrade the version of memos, use the following command.
 
-1. It has no external dependency.
-2. It requires zero config.
-3. 1 command to start backend and 1 command to start frontend, both with live reload support.
+```sh
+docker-compose down && docker image rm neosmemo/memos:latest && docker-compose up -d
+```

+Memos is built with a curated tech stack. It is optimized for developer experience and is very easy to start working on the code:
+
+1. It has no external dependency.
+2. It requires zero config.

+
+## Prerequisites
+
+- [Go](https://golang.org/doc/install)
+- [Air](https://github.com/cosmtrek/air#installation) for backend live reload
+- [Node.js](https://nodejs.org/)
+- [yarn](https://yarnpkg.com/getting-started/install)
+
+## Steps
+
+1. pull source code
+
+   ```bash
+   git clone https://github.com/usememos/memos
+   ```
+
+2. start backend using air(with live reload)
+
+   ```bash
+   air -c scripts/.air.toml
+   ```
+
+3. start frontend dev server
+
+   ```bash
+   cd web && yarn && yarn dev
+   ```
+
+Memos should now be running at [http://localhost:3000](http://localhost:3000) and change either frontend or backend code would trigger live reload.
