+
+
+**CocoaLumberjack** is a fast & simple, yet powerful & flexible logging framework for macOS, iOS, tvOS and watchOS.
+
+## How to get started
+
+First, install CocoaLumberjack via [CocoaPods](http://cocoapods.org), [Carthage](https://github.com/Carthage/Carthage), [Swift Package Manager](https://swift.org/package-manager/) or manually.
+Then use `DDOSLogger` for iOS 10 and later, or `DDTTYLogger` and `DDASLLogger` for earlier versions to begin logging messages.
+
+### CocoaPods
+
+```ruby
+platform :ios, '9.0'
+
+target 'SampleTarget' do
+  use_frameworks!
+  pod 'CocoaLumberjack/Swift'
+end
+```
+Note: `Swift` is a subspec which will include all the Obj-C code plus the Swift one, so this is sufficient.
+For more details about how to use Swift with Lumberjack, see [this conversation](https://github.com/CocoaLumberjack/CocoaLumberjack/issues/405).
+
+For Objective-C use the following:
+```ruby
+platform :ios, '9.0'
+
+target 'SampleTarget' do
+    pod 'CocoaLumberjack'
+end
+```
+
+### Carthage
+
+Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.
+
+To install with Carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage)
+
+Cartfile
+```
+github "CocoaLumberjack/CocoaLumberjack"
+```
+
+
+### Swift Package Manager
+
+As of CocoaLumberjack 3.6.0, you can use the Swift Package Manager as integration method.
+If you want to use the Swift Package Manager as integration method, either use Xcode to add the package dependency or add the following dependency to your Package.swift:
+
+```swift
+.package(url: "https://github.com/CocoaLumberjack/CocoaLumberjack.git", from: "3.7.0"),
+```
+
+Note that you may need to add both products, `CocoaLumberjack` and `CocoaLumberjackSwift` to your target since SPM sometimes fails to detect that `CocoaLumerjackSwift` depends on `CocoaLumberjack`.
+
+### Install manually
+
+If you want to install CocoaLumberjack manually, read the [manual installation](https://raw.githubusercontent.com/CocoaLumberjack/CocoaLumberjack/master/Documentation/GettingStarted.md#manual-installation) guide for more information.
+
+### Swift Usage
+
+Usually, you can simply `import CocoaLumberjackSwift`. If you installed CocoaLumberjack using CocoaPods, you need to use `import CocoaLumberjack` instead.
+
+```swift
+DDLog.add(DDOSLogger.sharedInstance) // Uses os_log
+
+let fileLogger: DDFileLogger = DDFileLogger() // File Logger
+fileLogger.rollingFrequency = 60 * 60 * 24 // 24 hours
+fileLogger.logFileManager.maximumNumberOfLogFiles = 7
+DDLog.add(fileLogger)
+
+...
+
+DDLogVerbose("Verbose")
+DDLogDebug("Debug")
+DDLogInfo("Info")
+DDLogWarn("Warn")
+DDLogError("Error")
+```
+
+### Obj-C usage
+
+If you're using Lumberjack as a framework, you can `@import CocoaLumberjack;`.
+Otherwise, `#import <CocoaLumberjack/CocoaLumberjack.h>`
+
+```objc
+[DDLog addLogger:[DDOSLogger sharedInstance]]; // Uses os_log
+
+DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; // File Logger
+fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
+fileLogger.logFileManager.maximumNumberOfLogFiles = 7;
+[DDLog addLogger:fileLogger];
+
+...
+
+DDLogVerbose(@"Verbose");
+DDLogDebug(@"Debug");
+DDLogInfo(@"Info");
+DDLogWarn(@"Warn");
+DDLogError(@"Error");
+```
+### Objective-C ARC Semantic Issue
+
+When integrating Lumberjack into an existing Objective-C it is possible to run into `Multiple methods named 'tag' found with mismatched result, parameter type or attributes` build error.
+
+Add `#define DD_LEGACY_MESSAGE_TAG 0` before importing CocoaLumberjack or add `#define DD_LEGACY_MESSAGE_TAG 0` or add `-DDD_LEGACY_MESSAGE_TAG=0` to *Other C Flags*/*OTHER_CFLAGS* in your Xcode project.
+
+## [swift-log](https://github.com/apple/swift-log) backend
+
+CocoaLumberjack also ships with a backend implementation for [swift-log](https://github.com/apple/swift-log).
+Simply add CocoaLumberjack as dependency to your SPM target (see above) and also add the `CocoaLumberjackSwiftLogBackend` product as dependency to your target.
+
+You can then use `DDLogHandler` as backend for swift-log, which will forward all messages to CocoaLumberjack's `DDLog`. You will still configure the loggers and log formatters you want via `DDLog`, but writing log messages will be done using `Logger` from swift-log.
+
+In your own log formatters, you can make use of the `swiftLogInfo` property on `DDLogMessage` to retrieve the details of a message that is logged via swift-log.

+
+## CocoaLumberjack 3
+
+### Migrating to 3.x
+
+* To be determined
+
+## Features
+
+### Lumberjack is Fast & Simple, yet Powerful & Flexible.
+
+It is similar in concept to other popular logging frameworks such as log4j, yet is designed specifically for Objective-C, and takes advantage of features such as multi-threading, grand central dispatch (if available), lockless atomic operations, and the dynamic nature of the Objective-C runtime.
+
+### Lumberjack is Fast
+
+In most cases it is an order of magnitude faster than NSLog.
+
+### Lumberjack is Simple
+
+It takes as little as a single line of code to configure lumberjack when your application launches. Then simply replace your NSLog statements with DDLog statements and that's about it. (And the DDLog macros have the exact same format and syntax as NSLog, so it's super easy.)
+
+### Lumberjack is Powerful:
+
+One log statement can be sent to multiple loggers, meaning you can log to a file and the console simultaneously. Want more? Create your own loggers (it's easy) and send your log statements over the network. Or to a database or distributed file system. The sky is the limit.
+
+### Lumberjack is Flexible:
+
+Configure your logging however you want. Change log levels per file (perfect for debugging). Change log levels per logger (verbose console, but concise log file). Change log levels per xcode configuration (verbose debug, but concise release). Have your log statements compiled out of the release build. Customize the number of log levels for your application. Add your own fine-grained logging. Dynamically change log levels during runtime. Choose how & when you want your log files to be rolled. Upload your log files to a central server. Compress archived log files to save disk space...
+
+## This framework is for you if:
+
+-   You're looking for a way to track down that impossible-to-reproduce bug that keeps popping up in the field.
+-   You're frustrated with the super short console log on the iPhone.
+-   You're looking to take your application to the next level in terms of support and stability.
+-   You're looking for an enterprise level logging solution for your application (Mac or iPhone).

+## Data Collection Practices
+
+Per [App privacy details on the App Store](https://developer.apple.com/app-store/app-privacy-details/), Apple is requesting app developers to provide info about their data collection, us SDK maintainers must provide them with the same data.
+
+### Data collection by the framework
+
+**By default, CocoaLumberjack does NOT collect any data on its own.** 
+
+[See our Data Collection Practices list.](https://cocoalumberjack.github.io/DataCollection/index.html)
+
+### Indirect data collection through the framework
+
+CocoaLumberjack is a logging framework which makes it easy to send those logs to different platforms.
+
+This is why collecting data might happen quite easily, if app developers include any sensitive data into their log messages.
+
+**Important note: app developers are fully responsible for any sensitive data collected through our logging system!**
+
+In consequence, you must comply to the Apple's privacy details policy (mentioned above) and document the ways in which user data is being collected.
+Since the number of scenarios where data might be indirectly collected through CocoaLumberjack is quite large, it's up to you, as app developers, to properly review your app's code and identify those cases.
+What we can do to help is raise awareness about potential data collection through our framework.
+
+Private data includes but isn't limited to:
+
+- user info (name, email, address, ...)
+- location info
+- contacts
+- identifiers (user id, device id, ...)
+- app usage data
+- performance data
+- health and fitness info
+- financial info
+- sensitive info
+- user content
+- history (browsing, search, ...)
+- purchases
+- diagnostics
+- ...
+
+_Example_: `DDLogInfo("User: \(myUser)")` will add the `myUser` info to the logs, so if those are forwarded to a 3rd party or sent via email, that may qualify as data collection.

+/**
+ * Welcome to CocoaLumberjack!
+ *
+ * The project page has a wealth of documentation if you have any questions.
+ * https://github.com/CocoaLumberjack/CocoaLumberjack
+ *
+ * If you're new to the project you may wish to read "Getting Started" at:
+ * Documentation/GettingStarted.md
+ *
+ * Otherwise, here is a quick refresher.
+ * There are three steps to using the macros:
+ *
+ * Step 1:
+ * Import the header in your implementation or prefix file:
+ *
+ * #import <CocoaLumberjack/CocoaLumberjack.h>
+ *
+ * Step 2:
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
+ *
+ * Step 2 [3rd party frameworks]:
+ *
+ * Define your LOG_LEVEL_DEF to a different variable/function than ddLogLevel:
+ *
+ * // #undef LOG_LEVEL_DEF // Undefine first only if needed
+ * #define LOG_LEVEL_DEF myLibLogLevel
+ *
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel myLibLogLevel = DDLogLevelVerbose;
+ *
+ * Step 3:
+ * Replace your NSLog statements with DDLog statements according to the severity of the message.
+ *
+ * NSLog(@"Fatal error, no dohickey found!"); -> DDLogError(@"Fatal error, no dohickey found!");
+ *
+ * DDLog works exactly the same as NSLog.
+ * This means you can pass it multiple variables just like NSLog.

+ * This class provides a log formatter that prints the dispatch_queue label instead of the mach_thread_id.
+ *
+ * A log formatter can be added to any logger to format and/or filter its output.
+ * You can learn more about log formatters here:
+ * Documentation/CustomFormatters.md
+ *
+ * A typical `NSLog` (or `DDTTYLogger`) prints detailed info as `[<process_id>:<thread_id>]`.
+ * For example:
+ *
+ * `2011-10-17 20:21:45.435 AppName[19928:5207] Your log message here`
+ *
+ * Where:
+ * `- 19928 = process id`
+ * `-  5207 = thread id (mach_thread_id printed in hex)`
+ *
+ * When using grand central dispatch (GCD), this information is less useful.
+ * This is because a single serial dispatch queue may be run on any thread from an internally managed thread pool.
+ * For example:
+ *
+ * `2011-10-17 20:32:31.111 AppName[19954:4d07] Message from my_serial_dispatch_queue`
+ * `2011-10-17 20:32:31.112 AppName[19954:5207] Message from my_serial_dispatch_queue`
+ * `2011-10-17 20:32:31.113 AppName[19954:2c55] Message from my_serial_dispatch_queue`
+ *
+ * This formatter allows you to replace the standard `[box:info]` with the dispatch_queue name.
+ * For example:
+ *
+ * `2011-10-17 20:32:31.111 AppName[img-scaling] Message from my_serial_dispatch_queue`
+ * `2011-10-17 20:32:31.112 AppName[img-scaling] Message from my_serial_dispatch_queue`
+ * `2011-10-17 20:32:31.113 AppName[img-scaling] Message from my_serial_dispatch_queue`
+ *
+ * If the dispatch_queue doesn't have a set name, then it falls back to the thread name.
+ * If the current thread doesn't have a set name, then it falls back to the mach_thread_id in hex (like normal).
+ *
+ * Note: If manually creating your own background threads (via `NSThread/alloc/init` or `NSThread/detachNeThread`),
+ * you can use `[[NSThread currentThread] setName:(NSString *)]`.

+/**
+ * Define the standard options.
+ *
+ * We default to only 4 levels because it makes it easier for beginners
+ * to make the transition to a logging framework.
+ *
+ * More advanced users may choose to completely customize the levels (and level names) to suite their needs.
+ * For more information on this see the "Custom Log Levels" page:
+ * Documentation/CustomLogLevels.md
+ *
+ * Advanced users may also notice that we're using a bitmask.
+ * This is to allow for custom fine grained logging:
+ * Documentation/FineGrainedLogging.md
+ *
+ * -- Flags --
+ *
+ * Typically you will use the LOG_LEVELS (see below), but the flags may be used directly in certain situations.
+ * For example, say you have a lot of warning log messages, and you wanted to disable them.
+ * However, you still needed to see your error and info log messages.
+ * You could accomplish that with the following:
+ *
+ * static const DDLogLevel ddLogLevel = DDLogFlagError | DDLogFlagInfo;
+ *
+ * When LOG_LEVEL_DEF is defined as ddLogLevel.
+ *
+ * Flags may also be consulted when writing custom log formatters,
+ * as the DDLogMessage class captures the individual flag that caused the log message to fire.
+ *
+ * -- Levels --
+ *
+ * Log levels are simply the proper bitmask of the flags.
+ *
+ * -- Booleans --
+ *
+ * The booleans may be used when your logging code involves more than one line.
+ * For example:
+ *
+ * if (LOG_VERBOSE) {
+ *     for (id sprocket in sprockets)
+ *         DDLogVerbose(@"sprocket: %@", [sprocket description])
+ * }
+ *
+ * -- Async --
+ *
+ * Defines the default asynchronous options.
+ * The default philosophy for asynchronous logging is very simple:
+ *
+ * Log messages with errors should be executed synchronously.
+ *     After all, an error just occurred. The application could be unstable.
+ *
+ * All other log messages, such as debug output, are executed asynchronously.
+ *     After all, if it wasn't an error, then it was just informational output,
+ *     or something the application was easily able to recover from.
+ *
+ * -- Changes --
+ *
+ * You are strongly discouraged from modifying this file.
+ * If you do, you make it more difficult on yourself to merge future bug fixes and improvements from the project.
+ * Instead, create your own MyLogging.h or ApplicationNameLogging.h or CompanyLogging.h
+ *
+ * For an example of customizing your logging experience, see the "Custom Log Levels" page:
+ * Documentation/CustomLogLevels.md

+
+## What's for
+SDWebImageSVGKitPlugin is a SVG coder plugin for [SDWebImage](https://github.com/rs/SDWebImage/) framework, which provide the image loading support for [SVG](https://en.wikipedia.org/wiki/Scalable_Vector_Graphics) using [SVGKit](https://github.com/SVGKit/SVGKit) SVG engine.
+
+Note: iOS 13+/macOS 10.15+ supports native SVG rendering (called [Symbol Image](https://developer.apple.com/documentation/uikit/uiimage/configuring_and_displaying_symbol_images_in_your_ui/)), with system framework to load SVG. Check [SDWebImageSVGCoder](https://github.com/SDWebImage/SDWebImageSVGCoder) for more information.
+
+## Example
+
+To run the example project, clone the repo, and run `pod install` from the Example directory first.
+
+You can modify the code or use some other SVG files to check the compatibility.
+
+## Requirements
+
++ iOS 8+
++ tvOS 9+
++ macOS 10.10+
+
+## Installation
+
+#### CocoaPods
+
+SDWebImageSVGKitPlugin is available through [CocoaPods](https://cocoapods.org). To install
+it, simply add the following line to your Podfile:
+
+```ruby
+pod 'SDWebImageSVGKitPlugin'
+```
+
+Note: The [SVGKit](https://github.com/SVGKit/SVGKit) dependency seems does not follow sem-version and didn't not release versions frequently. You can manually specify a branch or CID dependency for it. Like below:
+
+```
+pod 'SVGKit', :git => 'https://github.com/SVGKit/SVGKit.git', :branch => '3.x'
+```
+
+#### Carthage
+
+SDWebImageSVGKitPlugin is available through [Carthage](https://github.com/Carthage/Carthage).
+
+```
+github "SDWebImage/SDWebImageSVGKitPlugin"
+```
+
+## Usage
+
+### Use UIImageView (render SVG as bitmap image)
+
+To use SVG coder, you should firstly add the `SDImageSVGKCoder` to the coders manager. Then you can call the View Category method to start load SVG images.
+
+Because SVG is a [vector image](https://en.wikipedia.org/wiki/Vector_graphics) format, which means it does not have a fixed bitmap size. However, `UIImage` or `CGImage` are all [bitmap image](https://en.wikipedia.org/wiki/Raster_graphics). For `UIImageView`, we will only parse SVG with a fixed image size (from the SVG viewPort information). But we also support you to specify a desired size during image loading using `SDWebImageContextThumbnailPixelSize` context option. And you can specify whether or not to keep aspect ratio during scale using `SDWebImageContextImagePreserveAspectRatio` context option.
+
++ Objective-C
+
+```objectivec
+SDImageSVGKCoder *svgCoder = [SDImageSVGKCoder sharedCoder];
+[[SDImageCodersManager sharedManager] addCoder:svgCoder];
+UIImageView *imageView;
+// this arg is optional, if don't provide, use the viewport size instead
+CGSize svgImageSize = CGSizeMake(100, 100);
+[imageView sd_setImageWithURL:url placeholderImage:nil options:0 context:@{SDWebImageContextThumbnailPixelSize : @(svgImageSize)];
+```
+
++ Swift
+
+```swift
+let svgCoder = SDImageSVGKCoder.shared
+SDImageCodersManager.shared.addCoder(svgCoder)
+let imageView: UIImageView
+imageView.sd_setImage(with: url)
+// this arg is optional, if don't provide, use the viewport size instead
+let svgImageSize = CGSize(width: 100, height: 100)
+imageView.sd_setImage(with: url, placeholderImage: nil, options: [], context: [.imageThumbnailPixelSize : svgImageSize])
+```
+
+### Use SVGKImageView (render SVG as vector image)
+
+[SVGKit](https://github.com/SVGKit/SVGKit) also provide some built-in image view class for vector image loading (scale to any size without losing detail). The `SVGKLayeredImageView` && `SVGKFastImageView` are the subclass of `SVGKImageView` base class. We supports these image view class as well. You can just use the same API like normal `UIImageView`.
+
+For the documentation about `SVGKLayeredImageView`, `SVGKFastImageView` or `SVGKImageView`, check [SVGKit](https://github.com/SVGKit/SVGKit) repo for more information.
+
+**Note**: If you only use these image view class and don't use SVG on `UIImageView`, you don't need to register the SVG coder to coders manager. These image view loading was using the [Custom Image Class](https://github.com/rs/SDWebImage/wiki/Advanced-Usage#customization) feature of SDWebImage.
+
+**Attention**: These built-in image view class does not works well on `UIView.contentMode` property, you need to re-scale the layer tree after image was loaded. We provide a simple out-of-box solution to support it. Set the `sd_adjustContentMode` property to `YES` then all things done.
+
++ Objective-C
+
+```objectivec
+SVGKImageView *imageView; // can be either `SVGKLayeredImageView` or `SVGKFastImageView`
+imageView.contentMode = UIViewContentModeScaleAspectFill;
+imageView.sd_adjustContentMode = YES; // make `contentMode` works
+[imageView sd_setImageWithURL:url];
+```
+
++ Swift:
+
+```swift
+let imageView: SVGKImageView // can be either `SVGKLayeredImageView` or `SVGKFastImageView`
+imageView.contentMode = .aspectFill
+imageView.sd_adjustContentMode = true // make `contentMode` works
+imageView.sd_setImage(with: url)
+```
+
+## Export SVG data
+
+`SDWebImageSVGKitPlugin` provide an easy way to export the SVG image generated from framework, to the original SVG data.
+
++ Objective-C
+
+```objectivec
+UIImage *image; // Image generated from SDWebImage framework, actually a `SDSVGKImage` instance.
+NSData *imageData = [image sd_imageDataAsFormat:SDImageFormatSVG];
+```
+
++ Swift
+
+```swift
+let image: UIImage // Image generated from SDWebImage framework, actually a `SDSVGKImage` instance.
+let imageData = image.sd_imageData(as: .SVG)
+```

+# SVGKit
+
+SVGKit is a Cocoa framework for rendering SVG files natively: it's fast and powerful. Some additional info and links [are on the wiki](https://github.com/SVGKit/SVGKit/wiki)
+
+
+## Versions:
+
+Latest info at: https://github.com/SVGKit/SVGKit/wiki/Versions
+
+  - v3.x = current "in development" branch with latest changes, fixes, features
+    - NB: this is now automatically selected in GitHub as the "default" branch when you visit SVGKit's project page
+        
+# Getting Started
+
+## Run the Demo - iOS
+
+1. Open up "Demo-iOS.xcodeproj", and run it (on simulator or device). Try different SVG's. Zoom, pan, and (with the Monkey only:) hit the "Animate" button. Tap the images to see bounding-boxes / hit dectection (might need you to hit the Debug button first)
+1. If you have ANY problems building the library and embedding it in your app, compare your build settings to the Demo-iOS build settings - if something's different, it's probably the problem.
+
+# Installation (add SVGKit to your app)
+
+You have 3 main options for installing SVGKit:
+
+1. Drag/drop the .framework file into your project <-- PREFERRED / RECOMMENDED
+1. Use CocoaPods
+1. Use Carthage
+1. Drag/drop the static library into your project, and configure the build settings in your project
+
+NB: the "static library" is our backwards-compatible, manual install that always works if you have problems with CocoaPods/Carthage/Framework.
+
+## OPTION 1: Use the Framework - drag, drop, done!
+
+1. Open "SVGKit-iOS.xcodeproj"
+1. Build the project once
+1. In Project Navigator, expand the Products folder
+1. Drag/drop SVGKit.framework into your app-project
+
+NB: Frameworks are the preferred way to use libraries in Xcode. But this is a new feature, it might have bugs. If you have ANY problems, please create an Issue, but also try the Static Library method below
+
+You MAY also need to manually add the following Apple Frameworks to your app:
+  - CoreText
+  - CoreImage
+  - libxml2.dylib
+  - QuartzCore
+  - CoreGraphics
+  - UIKit
+
+You MAY also need to add the following 3rd party Frameworks to your app (included with SVGKit):
+  - CocoaLumberjack (in the SVGKit-iOS project, select the "3rd-party-frameworks" folder, and drag/drop whichever versions you need: iOS, tvOS, etc)
+    Remember to embed the library too (should show under Target -> General -> Embedded Binaries)
+    
+## OPTION 2: Using CocoaPods
+[CocoaPods](https://github.com/CocoaPods/CocoaPods) is a dependency manager for CocoaTouch. To do CocoaPods, adding the following in your podfile:
+
+```
+pod 'SVGKit'
+```
+
+It is also recommended that you setup your podfile to get SVGKit from the latest branch (October 2018: currently 3.x).
+
+```
+pod 'SVGKit', :git => 'https://github.com/SVGKit/SVGKit.git', :branch => '3.x'
+```
+
+## OPTION 3: Using Carthage
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager for Cocoa. To use Carthage, adding the following in your Cartfile:
+
+```
+github "SVGKit/SVGKit"
+```
+
+It is also recommended that you setup your Cartfile to get SVGKit from the current version (October 2018: 3.x branch).
+
+```
+github "SVGKit/SVGKit" "3.x"
+```
+
+## OPTION 4: Build the static library
+
+We have a build script that automatically builds ALL versions of the library at once, and ships them as a single file: http://stackoverflow.com/questions/3520977/build-fat-static-library-device-simulator-using-xcode-and-sdk-4/3647187#3647187
+
+It's all setup already, all you need to do is:
+
+1. Open "SVGKit-iOS.xcodeproj", switch to "SVGKit-iOS" target and Build it (cmd-B)
+3. in left navbar, scroll to bottom, and open the "Products" section
+4. right click the library ("libSVGKitBLAHBLAH.a") and select "show in finder"
+5. GO UP ONE FOLDER
+6. select the "Debug-universal" (or Release-universal if you were building in Release mode) folder
+7. Drag/drop the .a file and the "usr" folder into your project (select the "Copy files" checkbox)
+8. In Build Settings, select "Other Linker Flags" and add "-ObjC"
+9. Edit your build settings and set "C/C++ Compiler Version" = "LLVM Compiler 2.0"
+10. Add ALL the frameworks and 3rd party libraries listed below (go to "Build Phases", and "Link Binary with Libraries"):
+  - CoreText
+  - CoreImage
+  - libxml2.dylib
+  - QuartzCore
+  - CoreGraphics
+  - UIKit
+
+
+Everything else is automatic.
+
+## Usage - OS X
+
+Added in version 2.1.0 / Autumn 2018: support for macOS.
+
+You can use nearly the same API like iOS. Including `SVGKFastImageView`, `SVGKLayeredImageView`, and you can use `SVGKImage.NSImage` to export SVG layer to bitmap image.
+
+We also provide a macOS demo for SVGKit. To run the Demo, open `Demo-OSX.xcodeproj` and built to run. You can browser the different SVG files using those two different type of view to check the compatibility.
+
+## Recipes for using the library
+
+Here are some old posts (some of these APIs have changed slightly since they were written) on using SVGKit, with advice on which methods to use and why:
+
+  - GETTING STARTED, plus NEW FEATURES:  http://t-machine.org/index.php/2012/12/31/svgkit-2013-usage/
+  - QUICK RECIPES for common uses:  http://t-machine.org/index.php/2013/01/02/svgkit-2013-recipes/
+     - additiona: How to scale an SVG image on screen: http://t-machine.org/index.php/2013/04/14/svgkit-scaling-svg-images/
+  - CONTRIBUTING to the project, CORE ARCHITECTURE: http://t-machine.org/index.php/2012/12/31/svgkit-2013-development/
+ 
+  - (November 2013): New (experimental) feature - writing SVG's out to disk, preserving any changes you made programmatically: http://t-machine.org/index.php/2013/11/17/svgkit-programmatic-editing-of-svg-files-on-ios/
