+## Smart Version Detection
+
+The workflow uses an intelligent three-tier detection system to identify which Python versions need testing:
+
+### How It Works
+
+When a PR is created from a pre-release branch (e.g., "November") to main:
+
+1. **New versions are created** and added to a pre-release (tagged with date, e.g., "2025.11.23")
+2. **Version directories are created** in `/bin` (e.g., `bin/python3.19.1/`, `bin/python3.25.0/`)
+3. **The releases.properties file is updated** via the releases.properties workflow
+4. **A PR is created** from the release branch to main
+5. **This workflow detects changed files** in `/bin` and extracts version numbers from directory names
+6. **Tests are run** against the version(s) found in releases.properties from that PR branch
+
+### Typical Workflow Process
+
+Here's how the smart detection works in a typical release workflow:
+
+1. **Pre-release Creation**: New Python versions (e.g., 3.19.1, 3.25.0) are added to a pre-release tagged with the date (e.g., "2025.11.23")
+
+2. **Directory Structure**: Version directories are created in `/bin`:
+   ```
+   bin/
+   ├── python3.19.1/
+   │   └── (version files)
+   └── python3.25.0/
+       └── (version files)
+   ```
+
+3. **Properties Update**: The `releases.properties` file is updated via the update-releases-properties workflow
+
+4. **PR Creation**: A PR is created from a release branch (e.g., "November") to main
+
+5. **Smart Detection**: The workflow automatically:
+   - Scans changed files in the PR
+   - Detects `bin/python3.19.1/` and `bin/python3.25.0/`
+   - Extracts versions: `3.19.1` and `3.25.0`
+   - Verifies these versions exist in `releases.properties`
+   - Runs tests only for these 2 versions (not all versions)
+
+6. **Efficiency**: Instead of testing 20+ versions, only the 2 new versions are tested, reducing CI time from 30+ minutes to ~10-20 minutes
+
+### Detection Methods
+
+#### 🥇 Primary Method: /bin Directory Detection
+
+The workflow scans for changes in the `/bin` directory and extracts version numbers from directory names:
+
+```
+bin/python3.19.1/some-file.txt  →  Detects version: 3.19.1
+bin/python3.25.0/another.txt    →  Detects version: 3.25.0
+```
+
+**Advantages:**
+- Most accurate - directly tied to actual version changes
+- Reduces CI runtime by testing only relevant versions
+- Automatically handles multiple versions in a single PR
+
+#### 🥈 Fallback Method: PR Title Detection
+
+If no `/bin` changes are detected, the workflow extracts version numbers from the PR title:
+
+```
+"Add Python 3.13.5 support"     →  Detects version: 3.13.5
+"Update 3.12.9 and 3.13.3"      →  Detects versions: 3.12.9, 3.13.3
+```
+
+**Use cases:**
+- Documentation updates mentioning specific versions
+- Configuration changes for specific versions
+- Manual testing requests
+
+#### 🥉 Final Fallback: Latest 5 Versions
+
+If no versions are detected by either method, the workflow tests the latest 5 versions from releases.properties:
+
+**Use cases:**
+- General infrastructure changes
+- Workflow updates
+- Changes that might affect all versions
+
 ## Triggering Tests
 
 ### Automatic Triggers
 
 Tests run automatically when:
 
 - **Push to main**: Tests latest version only
-- **Pull Request with pre-release files**: Tests versions detected from `.7z` filenames
-- **Pull Request with version in title**: Tests versions mentioned in PR title (fallback)
-- **Manual workflow dispatch**: Tests specified version or all versions
+- **Pull Request with /bin changes**: Tests versions detected from `/bin/pythonX.X.X/` directory names (Primary Method)
+- **Pull Request with version in title**: Tests versions mentioned in PR title (Fallback Method)
+- **Pull Request with other changes**: Tests latest 5 versions (Final Fallback)
+- **Manual workflow dispatch**: Tests specified version
 
 ### Manual Trigger

+4. Optionally specify a version to test (e.g., `3.13.5`)
 
-### PR Title Format
+### PR Title Format (Fallback Method)
 
-To test specific versions in a PR, include version numbers in the title:
+If your PR doesn't include `/bin` directory changes, you can trigger tests by including version numbers in the PR title:
 
 - ✅ `Add Python 3.13.5 support`
 - ✅ `Update docs for 3.12.9`
 - ✅ `Fix issue with Python 3.13.3 and 3.12.6.0`
-- ❌ `Update documentation` (no version, won't trigger tests unless releases.properties changed)
+- ✅ `Documentation update` (will test latest 5 versions as final fallback)
+
+### Efficiency Benefits
+
+The smart detection system significantly reduces CI runtime:
+
+- **Before**: All versions tested on every PR (~30+ minutes)
+- **After**: Only relevant versions tested (~5-10 minutes per version)
+- **Example**: PR with 2 new versions = ~10-20 minutes instead of 30+ minutes
