+
+## 🎯 System Overview
+
+The Mold Cost Calculator is a web-based application that calculates mold manufacturing costs based on various technical specifications and complexity factors. The system is designed for footwear industry professionals to get accurate cost estimates for different types of molds.
+
+### Key Features
+- **Multi-factor cost calculation** based on mold type, complexity, and texture
+- **Country-specific tax rates** for accurate regional pricing
+- **User management system** with role-based access control
+- **Comprehensive admin panel** for system oversight
+- **Real-time cost breakdown** with detailed component analysis
+
+---
+
+## 💰 Cost Calculation System
+
+### Base Calculation Formula
+
+The system uses a multi-layered calculation approach:
+
+```
+Total Cost = (Base Price + Complexity Cost + Texture Cost) × (1 + Tax Rate)
+```
+
+Where:
+- **Base Price** = DEFAULT_NET_BASE × Mold Type Factor
+- **Complexity Cost** = Base Price × (Slider Factor + Cavity Factor + High Sidewall Factor)
+- **Texture Cost** = Base Price × Texture Factor
+
+### Default Values
+- **DEFAULT_NET_BASE**: $12.50 (base unit cost)
+- **Tax Rates**: Varies by country (see below)
+
+---
+
+## 📊 Cost Factors & Pricing

+## ⚙️ System Configuration
+
+### Cost Factor Management
+
+#### Updating Cost Factors
+Cost factors are defined in `app/constants.py`:
+
+```python
+COST_FACTORS = {
+    'mold': {
+        'Flat': 1.0,
+        'Flat with Top/Heel Tip': 1.25,
+        # ... other factors
+    },
+    'complexity': {
+        'high_sidewall': 0.18,
+        'slider': 0.1,
+        'cavity': 0.12
+    },
+    'texture': {
+        'adidas_digital': 0.0,
+        'customized texture': 0.15,
+        'laser': 0.2
+    }
+}
+```
+
+#### Updating Tax Rates
+Tax rates are also in `app/constants.py`:
+
+```python
+TAX_RATES = {
+    'China': 0.06,
+    'Vietnam': 0.10,
+    'Indonesia': 0.07
+}
+```
+
+#### Updating Default Base Price
+Change `DEFAULT_NET_BASE` in `app/constants.py`:
+
+```python
+DEFAULT_NET_BASE = 12.5  # Change this value
+```
+
+### Database Management
+
+#### Creating Admin Users
+Use the CLI command to create admin users:
+
+```bash
+# Set environment variables
+export ADMIN_USERNAME="admin"
+export ADMIN_EMAIL="admin@company.com"
+export ADMIN_PASSWORD="secure_password"
+export ADMIN_COMPANY="Company Name"
+
+# Run the command
+flask init-db
+```
+
+#### Database Migrations
+The system uses Alembic for database migrations:
+
+```bash
+# Create a new migration
+flask db migrate -m "Description of changes"
+
+# Apply migrations
+flask db upgrade
+```
+
+### Environment Configuration

+# Automated Deployment with Podman and rsync
+
+This document describes how to automatically deploy the `mold_cost_calculator` application using Podman and rsync.
+
+---
+
+## 1. Build the Image Locally
+
+```
+podman build -t mold_cost_calculator:latest .
+```
+
+---
+
+## 2. Save the Image as a Tarball
+
+```
+podman save -o mold_cost_calculator.tar mold_cost_calculator:latest
+```
+
+---
+
+## 3. Transfer the Image to the Server Using rsync
+
+Replace `user@server1:/path/to/deploy/dir` with your actual server username and path:
+
+```
+rsync -avz mold_cost_calculator.tar user@server1:/path/to/deploy/dir/
+```
+
+---
+
+## 4. Load the Image on the Server
+
+SSH into your server and run:
+
+```
+podman load -i /path/to/deploy/dir/mold_cost_calculator.tar
+```
+
+---
+
+## 5. Stop and Remove the Old Container (if running)
+
+```
+podman stop mold_cost_calculator || true
+podman rm mold_cost_calculator || true
+```
+
+---
+
+## 6. Run the New Container
+
+```
+podman run -d --name mold_cost_calculator -p 5001:5001 --restart=always \
+  -v /path/to/instance:/app/instance \
+  -v /path/to/logs:/app/logs \
+  localhost/mold_cost_calculator:latest
+```
+- Adjust volume paths as needed.
+
+---
+
+## 7. (Optional) Automate with a Script
+
+Create a script `deploy.sh`:
+
+```bash
+#!/bin/bash
+set -e
+
+# 1. Build image
+podman build -t mold_cost_calculator:latest .
+
+# 2. Save image
+podman save -o mold_cost_calculator.tar mold_cost_calculator:latest
+
+# 3. Rsync to server
+rsync -avz mold_cost_calculator.tar user@server1:/path/to/deploy/dir/
+
+# 4. SSH and deploy on server
+ssh user@server1 <<'ENDSSH'
+  cd /path/to/deploy/dir/
+  podman load -i mold_cost_calculator.tar
+  podman stop mold_cost_calculator || true
+  podman rm mold_cost_calculator || true
+  podman run -d --name mold_cost_calculator -p 5001:5001 --restart=always \
+    -v /path/to/instance:/app/instance \
+    -v /path/to/logs:/app/logs \
+    localhost/mold_cost_calculator:latest
+ENDSSH
+```
+- Make it executable: `chmod +x deploy.sh`
+- Update all `/path/to/...` and `user@server1` as needed.
+
+---
+
+## Notes
+- Ensure Podman is installed on both local and server machines.
+- Adjust volume paths and ports as needed for your environment.
+- Nginx should be configured to reverse proxy to port 5001 on the server.
+- For further automation, consider using CI/CD tools.

+# Developer Guide
+
+This guide contains information relevant to developers working on the Mold Cost Calculator application, including the deployment process and other technical details.
+
+## Environments
+
+The application is set up with two distinct, isolated environments running on the `server1` host:
+
+-   **Production:** The live application accessible at `moldcost.jimmygan.com`.
+-   **Staging:** A complete replica of the production environment for testing, accessible at `dev.moldcost.jimmygan.com`.
+
+## Automated CI/CD Deployment Workflow (v2.0)
+
+The project uses a self-hosted Continuous Integration/Continuous Deployment (CI/CD) pipeline on the production server (`server1`). This is achieved using a "branch-aware" `post-receive` Git hook.
+
+### How It Works
+
+The deployment process is fully automated and triggered by `git push`:
+
+1.  A developer pushes code to a specific branch (`development` or `master`).
+2.  The push action is received by the bare Git repository located at `/var/repo/mold_cost_online_tool.git`.
+3.  The `post-receive` hook script is automatically triggered.
+4.  The script inspects the branch name:
+    -   If the push is to the `development` branch, it executes the **staging** deployment script (`redeploy.staging.sh`).
+    -   If the push is to the `master` branch, it executes the **production** deployment script (`redeploy.sh`).
+5.  The respective deployment script handles pulling the latest code, rebuilding the correct container image, and restarting the application services for that specific environment.
+
+This workflow provides a safe and automated way to test changes in a production-like staging environment before deploying them to the live production environment.
+

+    style I fill:#d4edda,stroke:#333
+    style K fill:#d4edda,stroke:#333
+```
+
+### Database Synchronization
+
+To ensure the staging environment has relevant data for testing, the production database is synced to the staging database automatically every night. This is handled by a cron job on the server that executes the `sync_prod_to_staging_db.sh` script. This process overwrites the staging database completely, ensuring a fresh, but isolated, dataset.
+
+The development database is `mold_cost_development` and runs in a container named `mold_cost_db_development`. It is completely isolated from the production database.
+
+To keep the development database populated with realistic data, we use a script to sync the production database to it.
+
+#### Database Sync Script
+
+The script `sync_prod_to_dev_db.sh` is located in the project root. It performs the following actions:
+1.  Dumps the entire contents of the `production` database.
+2.  Drops and recreates the `development` database.
+3.  Restores the dump into the `development` database.
+
+**WARNING:** This is a destructive operation for the development database. Any changes made directly to the development DB will be wiped out when the script runs.
+
+#### Automating with Cron
+
+To run this sync automatically, you should set up a cron job on the server (`server1`). A good practice is to run it nightly.
+
+1.  SSH into `server1`.
+2.  Open the crontab editor: `crontab -e`
+3.  Add the following line to run the script every day at 3:00 AM:
+    ```
+    0 3 * * * /home/jimmyg/mold_cost_online_tool/sync_prod_to_dev_db.sh
+    ```
+4.  Make sure the script is executable: `chmod +x /home/jimmyg/mold_cost_online_tool/sync_prod_to_dev_db.sh`
+
+Logs for the sync process are stored at `/home/jimmyg/mold_cost_online_tool/logs/db_sync.log`.
+
+## Finalizing Setup
+
+Once all the above is configured, the setup is complete. You can now:
+*   Push to the `development` branch to deploy to `dev.moldcost.jimmygan.com`.
+*   Push to the `master` branch to deploy to `moldcost.jimmygan.com`.
+*   Have the development database automatically sync with production data nightly.
+
+You should perform a one-time, manual run of the sync script to initially populate the development database.
