1. MetaGPT takes a **one line requirement** as input and outputs **user stories / competitive analysis / requirements / data structures / APIs / documents, etc.**
2. Internally, MetaGPT includes **product managers / architects / project managers / engineers.** It provides the entire process of a **software company along with carefully orchestrated SOPs.**
   1. `Code = SOP(Team)` is the core philosophy. We materialize SOP and apply it to teams composed of LLMs.

## Examples (fully generated by GPT-4)

For example, if you type `python startup.py "Design a RecSys like Toutiao"`, you would get many outputs, one of them is data & api design

![Jinri Toutiao Recsys Data & API Design](docs/resources/workspace/content_rec_sys/resources/data_api_design.png)

It requires around **$0.2** (GPT-4 api's costs) to generate one example with analysis and design, around **$2.0** to a full project.

## Installation

### Traditional Installation

```bash
# Step 1: Ensure that NPM is installed on your system. Then install mermaid-js.
npm --version
sudo npm install -g @mermaid-js/mermaid-cli

# Step 2: Ensure that Python 3.9+ is installed on your system. You can check this by using:
python --version

# Step 3: Clone the repository to your local machine, and install it.
git clone https://github.com/geekan/metagpt
cd metagpt
python setup.py install
```

### Installation by Docker

```bash
# Step 1: Download metagpt official image and prepare config.yaml
docker pull metagpt/metagpt:v0.3
mkdir -p /opt/metagpt/{config,workspace}
docker run --rm metagpt/metagpt:v0.3 cat /app/metagpt/config/config.yaml > /opt/metagpt/config/config.yaml
vim /opt/metagpt/config/config.yaml # Change the config

# Step 2: Run metagpt demo with container
docker run --rm \
    --privileged \
    -v /opt/metagpt/config:/app/metagpt/config \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:v0.3 \
    python startup.py "Write a cli snake game"

# You can also start a container and execute commands in it
docker run --name metagpt -d \
    --privileged \
    -v /opt/metagpt/config:/app/metagpt/config \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:v0.3

docker exec -it metagpt /bin/bash
$ python startup.py "Write a cli snake game"
```

The command `docker run ...` do the following things:

- Run in privileged mode to have permission to run the browser
- Map host directory `/opt/metagpt/config` to container directory `/app/metagpt/config`
- Map host directory `/opt/metagpt/workspace` to container directory `/app/metagpt/workspace`
- Execute the demo command `python startup.py "Write a cli snake game"`

### Build image by yourself

```bash
# You can also build metagpt image by yourself.
git clone https://github.com/geekan/MetaGPT.git
cd MetaGPT && docker build -t metagpt:v0.3 .
```

## Configuration

- Configure your `OPENAI_API_KEY` in any of `config/key.yaml / config/config.yaml / env`
- Priority order: `config/key.yaml > config/config.yaml > env`

```bash
# Copy the configuration file and make the necessary modifications.
cp config/config.yaml config/key.yaml
```

| Variable Name                              | config/key.yaml                           | env                                             |
| ------------------------------------------ | ----------------------------------------- | ----------------------------------------------- |
| OPENAI_API_KEY # Replace with your own key | OPENAI_API_KEY: "sk-..."                  | export OPENAI_API_KEY="sk-..."                  |
| OPENAI_API_BASE # Optional                 | OPENAI_API_BASE: "https://<YOUR_SITE>/v1" | export OPENAI_API_BASE="https://<YOUR_SITE>/v1" |

## Tutorial: Initiating a startup

```shell
python startup.py "Write a cli snake game"
```

After running the script, you can find your new project in the `workspace/` directory.
