// Quick Matrix client setup
import 'package:rechain_matrix/rechain_matrix.dart';

final client = MatrixClient(
  homeserverUrl: 'https://matrix.rechain.network',
  userId: '@user:rechain.network',
);

# Quick Matrix client setup
from matrix_client import MatrixClient

client = MatrixClient('https://matrix.rechain.network')

# Start all services
docker compose up -d

# View logs
docker compose logs -f

1. Navigate to the relevant language folder
2. Copy the snippet file to your project
3. Follow the comments in the file for customization
4. Install required dependencies

# Copy the snippet
