+# Release Script Remote Detection Testing
+
+## Overview
+
+The improved `release.sh` script now intelligently detects the appropriate git remote to use for pushing release tags. This document describes the improvements and how to test them.
+
+## Improvements Made
+
+### 1. **Dynamic Remote Detection**
+
+Previously, the script hard-coded the remote name as `github`:
+```bash
+git push github "$RELEASE_TAG"  # Hard-coded, fails if remote has different name
+```
+
+Now, the script uses a helper function `get_github_remote()` to automatically detect the appropriate remote:
+```bash
+GITHUB_REMOTE=$(get_github_remote)
+git push "$GITHUB_REMOTE" "$RELEASE_TAG"  # Dynamic, works with any remote name
+```
+
+### 2. **Smart Priority System**
+
+The `get_github_remote()` function implements a priority-based selection:
+
+1. **Primary**: Remotes with `github.com` in the URL (e.g., `git@github.com:...`)
+   - Searches all configured remotes
+   - Selects the first one matching this pattern
+   - Ensures GitHub remotes are preferred
+
+2. **Fallback**: First available remote
+   - If no github.com remotes exist
+   - Uses the first remote in the list
+
+3. **Error**: No remotes found
+   - Script exits with error message
+   - Prevents unexpected behavior
+
+### 3. **Transparent Remote Display**
+
+The script now displays the selected remote at the start:
+
+```
+Using remote: github (git@github.com:wysaid/CameraCapture.git)
+```
+
+This allows users to verify the correct remote is being used before proceeding.
+
+## Test Scenarios
+
+### Scenario 1: Standard Setup (github.com + Local Upstream)
+
+**Configuration:**
+```bash
+github    git@github.com:wysaid/CameraCapture.git (fetch)
+github    git@github.com:wysaid/CameraCapture.git (push)
+origin    git@git.corp.kuaishou.com:facemagic/ccap.git (fetch)
+origin    git@git.corp.kuaishou.com:facemagic/ccap.git (push)
+```
+
+**Expected Behavior:**
+- Script detects both remotes
+- Prioritizes `github` (contains github.com)
+- Displays: `Using remote: github (git@github.com:wysaid/CameraCapture.git)`
+- Executes: `git push github v1.4.0`
+
+**Verification:**
+```bash
+./scripts/release.sh --dry-run
+# Look for: "Using remote: github" in output
+```
+
+### Scenario 2: Non-standard Remote Names
+
+**Configuration:**
+```bash
+upstream    git@github.com:wysaid/CameraCapture.git (fetch)
+upstream    git@github.com:wysaid/CameraCapture.git (push)
+internal    git@git.corp.kuaishou.com:facemagic/ccap.git (fetch)
+internal    git@git.corp.kuaishou.com:facemagic/ccap.git (push)
+```
+
+**Expected Behavior:**
+- Script detects `upstream` as GitHub remote (even though it's not named `github`)
+- Displays: `Using remote: upstream (git@github.com:wysaid/CameraCapture.git)`
+- Executes: `git push upstream v1.4.0`
+
+**Why This Matters:**
+- Developers with different remote naming conventions work seamlessly
+- Corporate environments with multiple remotes are supported
+- Fork/upstream patterns are automatically handled
+
+### Scenario 3: Only Local Upstream
+
+**Configuration:**
+```bash
+origin    git@git.corp.kuaishou.com:facemagic/ccap.git (fetch)
+origin    git@git.corp.kuaishou.com:facemagic/ccap.git (push)
+```
+
+**Expected Behavior:**
+- No github.com remote found
+- Script falls back to first available: `origin`
+- Displays: `Using remote: origin (git@git.corp.kuaishou.com:facemagic/ccap.git)`
+- Executes: `git push origin v1.4.0`
+
+**Note:** This works but isn't ideal for public releases to GitHub.
+
+### Scenario 4: No Remotes
+
+**Configuration:**
+```bash
+(no remotes configured)
+```
+
+**Expected Behavior:**
+- Script exits with error: `Error: No git remote found!`
+- Prevents accidental release creation
+- User must configure at least one remote
+
+## Implementation Details
+
+### Helper Function: `get_github_remote()`
+
+Located at the beginning of the script (lines 38-57):
+
+```bash
+get_github_remote() {
+    # First, try to find a remote with github.com in the URL
+    local github_remote=$(git remote -v | grep 'github\.com' | awk '{print $1}' | head -1)
+    
+    if [ -n "$github_remote" ]; then
+        echo "$github_remote"
+        return 0
+    fi
+    
+    # Fallback: return first available remote
+    local first_remote=$(git remote | head -1)
+    if [ -n "$first_remote" ]; then
+        echo "$first_remote"
+        return 0
+    fi
+    
+    # No remotes found
+    return 1
+}
+```
+
+### Usage in Script
+
+1. **Initialization (line 60):**
+   ```bash
+   GITHUB_REMOTE=$(get_github_remote)
+   ```
+
+2. **Validation (line 61-63):**
+   ```bash
+   if [ -z "$GITHUB_REMOTE" ]; then
+       exit 1
+   fi
+   ```
+
+3. **Display (line 70):**
+   ```bash
+   echo -e "  Using remote: ${GREEN}$GITHUB_REMOTE${NC} ($(git remote get-url "$GITHUB_REMOTE"))"
+   ```
+
+4. **Dry-run Command (line 314):**
+   ```bash
+   echo -e "  ${BLUE}git push $GITHUB_REMOTE $RELEASE_TAG${NC}"
+   ```
+
+5. **Actual Push (line 327):**
+   ```bash
+   git push "$GITHUB_REMOTE" "$RELEASE_TAG"
+   ```
+
+## Benefits
+
+✅ **Flexibility**: Works with any remote naming convention  
+✅ **Intelligence**: Automatically prioritizes GitHub remotes  
+✅ **Safety**: Prevents silent failures with unsupported remote configurations  
+✅ **Transparency**: Users see exactly which remote will be used  
+✅ **Robustness**: Graceful fallback for edge cases  
+✅ **Maintenance**: Script requires no manual configuration  
+
+## Migration Guide
+
+### For Existing Users
+
+**No changes required!** The script is fully backward compatible.
+
+If your project uses a remote named `github` pointing to github.com:
+- Script will detect and use it automatically
+- Behavior is identical to previous version
+
+If your project uses a different remote name:
+- Script will now work correctly instead of failing
+- No additional configuration needed
+
+### For New Projects
+
+Simply configure your remotes normally:
+```bash
+git remote add github https://github.com/yourusername/yourrepo.git
+git remote add origin https://internal-git.company.com/yourrepo.git
+```
+
+The script handles the rest automatically.
+
+## Testing the Changes
+
+### Quick Test: Dry-run Mode
+
+```bash
+# Test without actually creating tags
+./scripts/release.sh --dry-run
+
+# Expected output includes:
+# "Using remote: github (git@github.com:wysaid/CameraCapture.git)"
+# "git push github v1.4.0"  (or whichever remote is detected)
+```
+
+### Manual Test: Check Remote Detection
+
+```bash
+# Run the detection function in isolation
+bash -c '
+SCRIPT_DIR="/path/to/scripts"
+cd "$(dirname "$SCRIPT_DIR")"
+
+get_github_remote() {
+    local github_remote=$(git remote -v | grep "github\.com" | awk "{print \$1}" | head -1)
+    [ -n "$github_remote" ] && echo "$github_remote" && return 0
+    
+    local first_remote=$(git remote | head -1)
+    [ -n "$first_remote" ] && echo "$first_remote" && return 0
+    
+    return 1
+}
+
+echo "Detected remote: $(get_github_remote)"
+'
+```
+
+### Full Integration Test
+
+```bash
+# With version 1.4.0 prepared but not yet released:
+./scripts/release.sh --dry-run
+
+# Verify:
+# 1. Correct remote is shown
+# 2. All 7 validation steps pass
+# 3. Correct git commands would be executed
+# 4. Script exits with success
+```
