-See [developer README](README.dev.md).
+> listmonk is **alpha** software and may change and break. Use with caution. That said, it has been in active use at [zerodha.com](https://zerodha.com) for several months where it has processed hundreds of campaigns and tens of millions of e-mails.
+
+listmonk is a standalone newsletter and mailing list manager written in Go. It is fast, performant, and comes as a single binary. It uses a PostgreSQL database as its data store.
+
+### Installation and use
+
+- Download the [latest release](https://github.com/knadh/listmonk/releases) and extract the listmonk binary somewhere.
+- Copy `config.toml.sample` to `config.toml` and add your configuration (SMTP and Postgres DB credentials primarily).
+- `./listmonk --install` to setup the DB.
+- Visit `http://localhost:9000`.
+- Since there is no user auth yet, it's best to put listmonk behind a proxy like Nginx and setup basicauth on all endpoints except for the few endpoints that need to be public. Here is a [sample nginx config](https://github.com/knadh/listmonk/wiki/Production-Nginx-config) for production use.
+
+### Current features
