-## Prerequisites
+## Requirements
 
-- [NodeJS](https://nodejs.org/en/)
-- Node Package Manager ([NPM](https://www.npmjs.com/))
-- MongoDB
-- Redis
+- **[Bun](https://bun.sh/)** - runtime and package manager. `npm` / `yarn` / `pnpm` are **not** supported.
+- **[MongoDB](https://www.mongodb.com/)** - primary data store.
+- **[Redis](https://redis.io/)** (or a compatible drop-in such as [Dragonfly](https://www.dragonflydb.io/)) - cache layer.
+- **[Sonic](https://github.com/valeriansaliou/sonic)** - full-text search backend.
+- **[Kompressor](https://github.com/Kompakkt/Kompressor)** - mesh processing backend (3d meshes, gaussian splatting, point clouds, ...).
 
-## Development setup
+The Kompakkt configuration for Sonic is available at [`sonic-config.cfg`](https://github.com/Kompakkt/Mono/blob/main/sonic-config.cfg) in the Kompakkt/Mono repository.
 
-In order to setup your own development environment, you have to have [NodeJS](https://nodejs.org/en/) as well as Node Package Manager ([NPM](https://www.npmjs.com/)) installed.
+## Development setup
 
-Clone this repository, cd to the project directory and run the following commands:
+Clone the repository, then install the dependencies with Bun:
 
-```
-$ git clone https://github.com/Kompakkt/Common.git src/common
-$ npm i
+```bash
+git clone https://github.com/Kompakkt/Server
+cd Server
+bun install
 ```
 
-Ensure that MongoDB and Redis is running then start the server with
+Shared code from upstream Kompakkt packages (`@kompakkt/common`) is pulled in automatically as a git-pinned npm dependency.
 
+### Starting the supporting services
+
+Make sure MongoDB, Redis/Dragonfly, Sonic and Kompressor are running locally (see the `CONFIGURATION_*` environment variables in `src/configuration.ts` for the hostnames, ports and credentials the server expects by default). Also see "Running the full stack" below.
+
+### Starting the server
+
+For local development with hot reload:
+
+```bash
+bun run dev
 ```
-$ npm run start
-```
+
+The server listens on port **3030** by default.
+
+## Running the full stack
+
+This repository only contains the Server. To run Server, Repo and Viewer together (with all required supporting services such as Redis, Sonic, MongoDB and Kompressor), use the [Kompakkt/Mono](https://github.com/Kompakkt/Mono) development environment.
