 # Modmail v5 - WIP, UNSTABLE BUILD
 
-1. Fill in the configs from `config.yaml.example` and rename it to `config.yaml`
+> [!CAUTION]
+> This build of Modmail is currently a work in progress and is considered highly unstable and lacks essential features.
+> It is not recommended for general usage at this time. Please use the stable v4 release for production environments at https://github.com/modmail-dev/modmail.
+>
+> No migration effort will be made between pushes, bugs and vulnerabilities are expected, and data loss may occur if used.
+> We are also not accepting contributions through issues and pull requests for this branch at this time.

+1. Copy `config.yaml.example` and rename it to `config.yaml`, then edit it with your settings
 2. Install [uv](https://docs.astral.sh/uv/getting-started/installation/), then run `uv sync --locked --compile-bytecode --no-default-groups --extra speed --extra DBTYPE` to install the dependencies
    - Replace `DBTYPE` with `mongodb` or `sqlite`, only these two are supported at the moment
 3. Start the bot with `uv run python start.py`
