+# gRPC Distributed Computation
+````markdown
+This project demonstrates a distributed computation system using gRPC across three different languages:
+- Python for the Add service  
+- Node.js for the Multiply service  
+- Go for the client
+
+---
+
+## Running the Add Server (Python)
+
+1. Navigate to the Python service directory:
+
+   ```bash
+   cd pythonGRPC
+````
+
+2. Activate the virtual environment:
+
+   ```bash
+   source .bin/activate
+   ```
+
+3. Run the server:
+
+   ```bash
+   python3 server.py
+   ```
+
+---
+
+## Running the Multiply Server (Node.js)
+
+1. Navigate to the Node service directory:
+
+   ```bash
+   cd nodeGRPC
+   ```
+
+2. Start the server:
+
+   ```bash
+   node server.mjs
+   ```
+
+---
+
+## Running the Client (Go)
+
+1. Navigate to the Go client directory:
+
+   ```bash
+   cd goGRPC
+   ```
+
+2. To perform a calculation:
+
+   ```bash
+   go run main.go numberA numberB
+   ```
+
+   Example:
+
+   ```bash
+   go run main.go 9 9
+   ```
+
+3. To fetch logs from both servers:
+
+   ```bash
+   go run main.go logs
+   ```
+
+---
+
+## Example Usage
+
+```bash
+# Run a new calculation
+go run main.go 9 9
+
+# Stream previous logs from Add and Multiply services
+go run main.go logs
+```
+
+---
+
+Make sure both servers are running before executing the Go client.
+
+```
+```
