# How to Update Remote Origin

## Method 1: Change Existing Remote URL (Recommended)

If you already have a remote set and want to change it:

```powershell
# View current remote
git remote -v

# Option A: Update with HTTPS URL
git remote set-url origin https://github.com/YOUR_USERNAME/YOUR_REPO_NAME.git

# Option B: Update with SSH URL
git remote set-url origin git@github.com:YOUR_USERNAME/YOUR_REPO_NAME.git

# Verify the change
git remote -v
```

---

## Method 2: Remove and Re-add Remote

If you want to completely remove and add a new remote:

```powershell
# Remove existing remote
git remote remove origin

# Add new remote
git remote add origin https://github.com/YOUR_USERNAME/YOUR_REPO_NAME.git

# Verify
git remote -v
```

---

## Method 3: Using Your GitHub Repository

### Step 1: Create Repository on GitHub
1. Go to https://github.com/new
2. Repository name: `RAG-Capstone-Project`
3. Description: `Retrieval-Augmented Generation system with TRACE evaluation`
4. Select Public or Private
5. **IMPORTANT**: Don't initialize with README, .gitignore, or license
6. Click "Create repository"

### Step 2: Copy Your Repository URL
After creating, GitHub will show you the URL. Copy it (should look like):
```
https://github.com/YOUR_USERNAME/RAG-Capstone-Project.git
```

### Step 3: Update Remote in Your Local Repository
```powershell
cd "D:\CapStoneProject\RAG Capstone Project"

git remote set-url origin https://github.com/YOUR_USERNAME/RAG-Capstone-Project.git

# Verify
git remote -v
```

## Complete Step-by-Step Example

Let's say your GitHub username is `john-doe`:

```powershell
# 1. Navigate to project
cd "D:\CapStoneProject\RAG Capstone Project"

# 2. Update the remote URL
git remote set-url origin https://github.com/john-doe/RAG-Capstone-Project.git

# 3. Verify it was updated
git remote -v

# 4. Push to GitHub (first time)
git push -u origin main

# 5. For future pushes (just use)
git push
```

## Using SSH Instead of HTTPS

### Step 1: Generate SSH Key (if you don't have one)
```powershell
ssh-keygen -t ed25519 -C "your_email@example.com"
```

### Step 2: Add SSH Key to GitHub
1. Copy the public key: `cat ~/.ssh/id_ed25519.pub`
2. Go to https://github.com/settings/keys
3. Click "New SSH key"
4. Paste your public key
5. Save

### Step 3: Update Remote to SSH
```powershell
git remote set-url origin git@github.com:YOUR_USERNAME/RAG-Capstone-Project.git

# Verify
git remote -v

# Test connection
ssh -T git@github.com
```

## Troubleshooting

### Problem: "fatal: remote origin already exists"
```powershell
# Remove the old remote first
git remote remove origin

# Then add the new one
git remote add origin https://github.com/YOUR_USERNAME/RAG-Capstone-Project.git
```

### Problem: "Permission denied (publickey)"
This means SSH authentication failed. Use HTTPS instead:
```powershell
git remote set-url origin https://github.com/YOUR_USERNAME/RAG-Capstone-Project.git
```

### Problem: "fatal: Authentication failed"
This means your GitHub credentials are incorrect. Use a Personal Access Token:
1. Generate token: https://github.com/settings/tokens
2. When pushing, use the token as password

### Check Current Configuration
```powershell
# View remote URLs
git remote -v

# View detailed remote info
git remote show origin

# View git config
git config --local -l
```
