 # Harmony
 
 ## Description
-Harmony aims to provide secure, robust, and open source encrypted communication with high call quality. It is designed for individuals, communities, as well as enterprises with a space and channel structure. In addition to providing a secure communication platform, developers may build upon the platform much easier than other platforms.

It is designed for individuals, communities, as well as organizations with a space and channel structure. In addition to providing a secure communication platform, developers may build upon the platform much easier than other platforms.  
 
 This repository includes the core server software. It's free to self-host or use any hosted instance. Enterprise customers will have the option to purchase support services and hosted instances. Authentication is meant to be used with the [Nextania account services](https://github.com/nextania/account). OAuth2 will be supported in the future.
 
-The Harmony client currently only exists for browsers. Other clients will be developed in the future.

 Note: Harmony is not a federated service for the sake of simplicity. It is a centralized service that can be self-hosted.
 
+## How to run
+You will need Rust, MongoDB, and Redis before running the server.
+The following environment variables need to be set:
+`MONGODB_URI` - The URI to the MongoDB database.
+`MONGODB_DATABASE` - The name of the MongoDB database.
+`REDIS_URI` - The URI to the Redis database.
+`JWT_SECRET` - The secret used for JWTs.
+To run the server, you can use `cargo run --bin harmony`.
+
+In addition, if you would like to run the WebRTC voice node, you will need to set the following environment variables:
+`REDIS_URI` - The URI to the Redis database.
+`REGION` - The region of the voice node.
+To run the voice node, you can use `cargo run --bin pulse`.
+
+The voice node needs to be run using a server with a public IP address for WebRTC to function properly. Additionally, a sizeable amount of bandwidth is required.
