+If your changes add, remove, or move source files in the `Source/` directory, you **must** regenerate the SPM symlink structure:
+
+```bash
+# Regenerate SPM layout
+swift scripts/generate_spm_sources_layout.swift

+
+**Important:** Always include the generated `spm/Sources` directory changes in your pull request. The CI will fail if the SPM layout is out of sync with the source files. Our build script automatically verifies this by cleaning and regenerating the layout during testing.

+//
+// This package provides source distribution for Texture with Swift Package Manager.
+//
+// Features:
+//   - Core AsyncDisplayKit (all nodes, layout specs, TextNode2)
+//   - PINRemoteImage integration
+//   - IGListKit Swift wrapper (TextureIGListKitExtensions)
+//
+// IGListKit Integration:
+//   The native Objective-C IGListKit API (IGListAdapter+AsyncDisplayKit, etc.) is disabled
+//   because it requires conditional compilation flags (AS_IG_LIST_KIT=1) which create
+//   Objective-C headers that cannot be bridged to Swift. Instead, use the Swift wrapper:
+//
+//   - Import: TextureIGListKitExtensions
+//   - API: adapter.setCollectionNode(node) instead of adapter.setASDKCollectionNode(node)
+//   - See Sources/TextureIGListKitExtensions/README.md for complete API mapping
+//
+// Other Limitations:
+//   - Video/MapKit/Photos features not accessible (require framework linking)
+//   - Old TextNode disabled (use modern TextNode2)

+
+### Swift Package Manager
+
+Texture supports Swift Package Manager with Package Traits for modular feature integration.
+
+#### Basic Usage (AsyncDisplayKit only)
+
+Most users just need the core AsyncDisplayKit functionality:
+
+```swift
+// In your Package.swift
+dependencies: [
+    .package(url: "https://github.com/TextureGroup/Texture.git", from: "3.3.0")
+],
+targets: [
+    .target(
+        name: "YourApp",
+        dependencies: [
+            .product(name: "AsyncDisplayKit", package: "Texture")
+        ]
+    )
+]
+```
+
+**Default Features (included automatically):**
+- Core AsyncDisplayKit (ASDisplayNode, ASImageNode, ASTextNode2, ASButtonNode, etc.)
+- PINRemoteImage integration (ASPINRemoteImageDownloader)
+- Collection views (ASCollectionNode, ASTableNode)
+- Layout specs (ASStackLayoutSpec, ASInsetLayoutSpec, etc.)
+- TextNode2 (modern text rendering, replaces legacy TextNode)
+
+**Optional Features (enable via traits):**
+- IGListKit integration (advanced collection views with modern Swift API)
+
+**⚠️ SPM Limitations:**
+Video (ASVideoNode), MapKit (ASMapNode), and Photos features are **not available** via Swift Package Manager due to technical limitations. These Objective-C classes are wrapped in conditional compilation directives (`#if AS_USE_VIDEO`) which prevents them from being exported in the Swift module interface.
+
+**If you need Video/MapKit/Photos features:**
+- Use **CocoaPods** or **Carthage** (full feature support)
+- Or use these features from **Objective-C code** (.m files)
+
+**Future directions:** We're exploring solutions like Swift wrapper modules (TextureVideoExtensions, TextureMapKitExtensions) to provide Swift API for these features via SPM.
+
+#### Advanced Usage: IGListKit Integration
+
+For advanced collection view support with IGListKit, you need **both steps**:
+
+1. **Enable the IGListKit trait** on the package dependency
+2. **Add the TextureIGListKitExtensions product** to your target
+
+```swift
+// In your Package.swift
+dependencies: [
+    .package(
+        url: "https://github.com/TextureGroup/Texture.git",
+        from: "3.3.0",
+        traits: [.init(name: "IGListKit")]  // Step 1: Enable trait
+    )
+],
+targets: [
+    .target(
+        name: "YourApp",
+        dependencies: [
+            .product(name: "AsyncDisplayKit", package: "Texture"),
+            .product(name: "TextureIGListKitExtensions", package: "Texture")  // Step 2: Add product
+        ]
+    )
+]
+```
+
+**Why both steps?** Due to Swift Package Manager limitations, traits apply to the entire package, not individual products. This means you must explicitly enable the IGListKit trait AND add the product dependency. See [Issue #8350](https://github.com/swiftlang/swift-package-manager/issues/8350) for details.
+
+**⚠️ Important Notes:**
+- **SPM uses IGListKit 5.0+** (breaking changes from 4.x used in CocoaPods/Carthage)
+- **Not a drop-in replacement** - migration and testing required
+- **No Carthage/CocoaPods support planned** - we recommend migrating to SPM
+- Provides Swift API: `ListAdapter.setCollectionNode(_:)` (replaces Objective-C `setASDKCollectionNode:`)
+
+📖 **[Read the full IGListKit migration guide →](Sources/TextureIGListKitExtensions/README.md)**
+
+#### Migrating from CocoaPods to SPM
+
+If you're migrating from CocoaPods, here's how the subspecs map to SPM features:
+
+| Feature | CocoaPods | SPM | Notes |
+|---------|-----------|-----|-------|
+| **Core** | `pod 'Texture'` (default) | `.product(name: "AsyncDisplayKit", ...)` | ✅ Always included |
+| **PINRemoteImage** | Included by default | Always included | ✅ Same behavior |
+| **Video** | Included by default | **Not available** | ❌ SPM limitation (see above) |
+| **MapKit** | Included by default | **Not available** | ❌ SPM limitation (see above) |
+| **Photos** | Included by default | **Not available** | ❌ SPM limitation (see above) |
+| **AssetsLibrary** | Included by default | **Removed** | ❌ Deprecated iOS 9.0, use Photos |
+| **IGListKit** | `pod 'Texture/IGListKit'` | Optional trait + product | ⚠️ Uses IGListKit 5.0+ |
+| **TextNode2** | `pod 'Texture/TextNode2'` | Enabled by default | ✅ Modern TextNode used |
+| **Yoga** | `pod 'Texture/Yoga'` | Not supported | Add as separate dependency |
+
+**Key differences:**
+- **TextNode2 is default**: SPM uses the modern TextNode implementation automatically (no legacy TextNode)
+- ❌ **Video/MapKit/Photos not available**: Due to Swift Package Manager limitations with conditionally compiled Objective-C classes
+- ❌ **AssetsLibrary removed**: Deprecated in iOS 9.0, use Photos framework instead
+- ⚠️ **IGListKit version**: SPM uses IGListKit 5.0+ instead of 4.x (breaking changes)
+- ℹ️ **Yoga**: Not integrated in SPM - add Yoga as a separate dependency if needed
+
+#### Note for Contributors
+
+When adding or removing source files in the `Source/` directory, you must regenerate the SPM symlink structure:
+
+```bash
+# Regenerate SPM layout
+swift scripts/generate_spm_sources_layout.swift
+
+# Commit the generated changes
+git add spm/Sources
+git commit -m "Update SPM layout for new/removed files"
+```
+
+**Important:** Always commit the generated `spm/Sources` directory changes along with your source file changes. This ensures SPM users can build the project correctly.
