 Installation
 ============
 
- 1. Download both `NanoVG` and `MetalNanoVG` source codes.
- 2. Add both `NanoVG` and `MetalNanoVG`'s `src` directories to the header search
-    path.
- 3. Add `NanoVG`'s `src/nanovg.c` and `MetalNanoVG`'s `src/nanovg_mtl.m` to
-    the `Compile Sources` section in Xcode.
- 4. Link the `Metal` and `QuartzCore` frameworks.
- 5. For best performance, disable *GPU Frame Capture* and *Metal API Validation* as described [here](https://developer.apple.com/library/content/documentation/Miscellaneous/Conceptual/MetalProgrammingGuide/Dev-Technique/Dev-Technique.html#//apple_ref/doc/uid/TP40014221-CH8-SW3).

+## Swift
+
+1. Import.
+
+```Swift
+import MetalNanoVG
+```
+2. Pass the `CAMetalLayer` object when creating the NanoVG context.
+
+```Swift
+let layer = CAMetalLayer()
+let nvg = nvgCreateMTL(Unmanaged.passUnretained(layer).toOpaque(), Int32(NVG_ANTIALIAS.rawValue))
+```
+
+## Objective-C
