-## Running NATS and Consul (Development Only)
-
-> ⚠️ This setup is insecure and should only be used for development. For production, use a secure cluster environment with TLS certificates.
-
-### Docker Compose Configuration
-
-Create a `docker-compose.yaml` file:
-
-```yaml
-version: "3"
-
-services:
-  nats-server:
-    image: nats:latest
-    container_name: nats-server
-    command: -js --http_port 8222
-    ports:
-      - "4222:4222"
-      - "8222:8222"
-      - "6222:6222"
-    tty: true
-    restart: always
-
-  consul:
-    image: consul:1.15.4
-    container_name: consul
-    ports:
-      - "8500:8500"
-      - "8601:8600/udp"
-    command: "agent -server -ui -node=server-1 -bootstrap-expect=1 -client=0.0.0.0"
-    restart: always
-```
-
-### Start the Services
-
-```bash
-docker compose up -d
-```
-
----
-
-## Generate Peer Configuration
-
-```bash
-mpcium-cli generate-peers -n 3
-```
-
-Example output:
-
-```json
-{
-  "node0": "12345678-1234-1234-1234-123456789abc",
-  "node1": "23456789-2345-2345-2345-23456789abcd",
-  "node2": "34567890-3456-3456-3456-3456789abcde"
-}
-```
-
----
-
-## Cluster Configuration
-
-### 1. Create and Update `config.yaml`
-
-```bash
-cp config.yaml.template config.yaml
-```
-
-Edit `config.yaml`:
-
-```yaml
-nats:
-  url: nats://127.0.0.1:4222
-consul:
-  address: localhost:8500
-
-mpc_threshold: 2
-environment: development
-badger_password: "your_badger_password"
-event_initiator_pubkey: "your_event_initiator_pubkey"
-```
-
-### Generate a Strong Password (Recommended)
-
-```bash
-< /dev/urandom tr -dc 'A-Za-z0-9!@#$^&*()-_=+[]{}|;:,.<>?/~' | head -c 16; echo
-```
-
-Example:
-
-```yaml
-badger_password: "F))ysJp?E]ol&I;^"
-```
-
-### 2. Register Peers to Consul
-
-```bash
-mpcium-cli register-peers
-```
-
----
-
-## Event Initiator Setup
-
-### Generate the Initiator
-
-```bash
-mpcium-cli generate-initiator
-```
-
-> 💡 Use `--encrypt` in production.
-
-### Add Public Key to `config.yaml`
-
-From `event_initiator.identity.json`:
-
-```json
-{
-  "public_key": "09be5d070816aadaa1b6638cad33e819a8aed7101626f6bf1e0b427412c3408a"
-}
-```
-
-Update `config.yaml`:
-
-```yaml
-event_initiator_pubkey: "09be5d070816aadaa1b6638cad33e819a8aed7101626f6bf1e0b427412c3408a"
-```
-
----
-
-## Configure Node Identities
-
-### 1. Create Node Folders
-
-```bash
-mkdir node{0..2}
-for dir in node{0..2}; do
-  cp config.yaml peers.json "$dir/"
-  mkdir -p "$dir/identity"
-done
-```
-
-### 2. Generate Identity for Each Node
-
-Example for `node0`:
-
-```bash
-cd node0
-mpcium-cli generate-identity --node node0
-```
-
-> 💡 For production, use encryption:
->
-> ```bash
-> mpcium-cli generate-identity --node node0 --encrypt
-> ```
-
-### Generate Strong Password for Encryption
-
-```bash
-< /dev/urandom tr -dc 'A-Za-z0-9!@#$^&*()-_=+[]{}|;:,.<>?/~' | head -c 16; echo
-```
-
-### 3. Distribute Identity Files to All Nodes
-
-```bash
-cp identity/node0_identity.json ../node1/identity/node0_identity.json
-cp identity/node0_identity.json ../node2/identity/node0_identity.json
-```
-
-Repeat this for `node1` and `node2`.
-
-### Folder Structure Example
-
-```
-├── node0
-│   ├── config.yaml
-│   ├── identity
-│   │   ├── node0_identity.json
-│   │   ├── node0_private.key
-│   │   ├── node1_identity.json
-│   │   └── node2_identity.json
-│   └── peers.json
-├── node1
-│   ├── config.yaml
-│   ├── identity
-│   │   ├── node0_identity.json
-│   │   ├── node1_identity.json

-│   │   ├── node1_identity.json
-│   │   ├── node2_identity.json
-│   │   └── node2_private.key
-│   └── peers.json

-## Start Mpcium Nodes
-
-Start each node:
-
-```bash
-cd node0
-mpcium start -n node0
-```
-
-```bash
-cd node1
-mpcium start -n node1
-```
+### Set everything up in one go
 
 ```bash
-cd node2
-mpcium start -n node2
+. setup.sh
 ```
 
-> 💡 In production, avoid hardcoded passwords:
->
-> ```bash
-> mpcium start -n node0 --prompt-credentials
-> ```
+Detailed steps can be found in [SETUP.md](SETUP.md).
