+# CRM Customer Management System
+
+A web-based CRM system built with Go backend and HTML/CSS/JavaScript frontend.
+
+## Features
+
+1. **Customer Management**
+   - Create customers with fields: Customer Name, Intended Product
+   - Customer list with fields: Time, Customer, Version, Description, Solution, Type, Module, Status & Progress, Reporter (all editable)
+   - Import customers from CSV files
+
+2. **Customer Dashboard**
+   - Visual charts (pie charts, line charts) for data analysis
+   - Filter data by date range
+   - View customer distribution by status, trends, product interest, and customer types
+
+## Technology Stack
+
+- Backend: Go
+- Frontend: HTML, CSS, JavaScript
+- Charts: Chart.js (via CDN)
+- Data Storage: Local JSON file
+
+## How to Run
+
+1. Navigate to the project directory:
+   ```bash
+   cd /Users/d-robotics/crm/crm-go
+   ```
+
+2. Run the server:
+   ```bash
+   ./bin/server
+   ```
+
+3. Open your browser and go to:
+   ```
+   http://localhost:8080
+   ```
+
+## Usage
+
+### Customer Management
+- Click "Customer Management" in the navigation
+- Add new customers using the form
+- Edit existing customers by clicking "Edit" button
+- Delete customers by clicking "Delete" button
+- Import customers from CSV file using the import form
+
+### Dashboard
+- Click "Dashboard" in the navigation
+- View various charts showing customer data
+- Filter data by date range
+
+## Data Storage
+
+Customer data is stored in `./data/customers.json` in JSON format.
+
