 ## Windows Development Setup
 
+### Step 1: Configure Git for Gitea
+
+#### Option A: Using Personal Access Token (Most Secure)
+1. Go to your Gitea instance: `https://gitea.casaparma.dscloud.me`
+2. Navigate to Settings → Applications → Generate New Token
+3. Copy the generated token
+4. Configure Git credentials:
+
+```bash
+git config --global credential.helper store
+git config --global user.name "Your-Gitea-Username"
+git config --global user.email "your-email@domain.com"
+```
+
+5. Clone the repository:
+```bash
+git clone https://gitea.casaparma.dscloud.me/Miguel/SIDEL_ScriptsManager.git
+```
+
+6. When prompted, use your username and the **token** as password.
+
+#### Option B: Using Username in URL (Quick Setup)
+```bash
+git clone https://YOUR-USERNAME@gitea.casaparma.dscloud.me/Miguel/SIDEL_ScriptsManager.git
+cd SIDEL_ScriptsManager
+```
+
+This will prompt for password only once and store it securely.

+## Git Configuration Troubleshooting
+
+### Credential Issues
+
+If you're repeatedly asked for credentials:
+
+```bash
+# Check current configuration
+git config --list | grep credential
+
+# Reset credential helper
+git config --global --unset credential.helper
+git config --global credential.helper store
+
+# For Gitea specifically, use username in URL
+git remote set-url origin https://USERNAME@gitea.casaparma.dscloud.me/Miguel/SIDEL_ScriptsManager.git
+```
+
+### Token Authentication
+
+When using Personal Access Tokens:
+- Username: Your Gitea username
+- Password: The generated token (NOT your regular password)

+### Windows-Specific Git Issues
+
+```bash
+# If you get line ending warnings
+git config --global core.autocrlf true
+
+# If you get filename issues
+git config --global core.protectNTFS false
+```
+
+### Verify Your Configuration
+
+```bash
+# Test your setup
+git fetch origin
+git status
+
+# Check remotes
+git remote -v
+
+# Check user configuration
+git config user.name
+git config user.email
