+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at yo@massappeal.co. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

 ## Overview
 
 SideMenu is a simple and versatile side menu control written in Swift.
- * **It can be implemented in storyboard without a single line of [code](#code-less-storyboard-implementation).**
- * Four standard animation styles to choose from (there's even a parallax effect if you want to get weird).
- * Highly customizable without needing to write tons of custom code.
- * Supports continuous swiping between side menus on boths sides in a single gesture.
- * Global menu configuration. Set-up once and be done for all screens.
- * Menus can be presented and dismissed the same as any other view controller since this control uses [custom transitions](https://developer.apple.com/library/content/featuredarticles/ViewControllerPGforiPhoneOS/CustomizingtheTransitionAnimations.html).
- * Animations use your view controllers, not snapshots.
- * Properly handles screen rotation and in-call status bar height changes.

+#### UISideMenuNavigationController

+/// SideMenuManager instance associated with this menu. Default is `SideMenuManager.default`. This property cannot be changed after the menu has loaded.
+open weak var sideMenuManager: SideMenuManager! = SideMenuManager.default

+

+@IBInspectable open var leftSide: Bool = false
+
+/// Indicates if the menu is anywhere in the view hierarchy, even if covered by another view controller.
+open var isHidden: Bool
+```
+#### UISideMenuNavigationControllerDelegate
+To receive notifications when a menu is displayed from a view controller, have it adhere to the  `UISideMenuNavigationControllerDelegate` protocol:
+``` swift
+extension MyViewController: UISideMenuNavigationControllerDelegate {
+
+    func sideMenuWillAppear(menu: UISideMenuNavigationController, animated: Bool) {
+        print("SideMenu Appearing! (animated: \(animated))")
+    }
+
+    func sideMenuDidAppear(menu: UISideMenuNavigationController, animated: Bool) {
+        print("SideMenu Appeared! (animated: \(animated))")
+    }
+
+    func sideMenuWillDisappear(menu: UISideMenuNavigationController, animated: Bool) {
+        print("SideMenu Disappearing! (animated: \(animated))")
+    }
+
+    func sideMenuDidDisappear(menu: UISideMenuNavigationController, animated: Bool) {
+        print("SideMenu Disappeared! (animated: \(animated))")
+    }
+
+}
+```
+### Advanced
+For simplicity, `SideMenuManager.default` serves as the primary instance as most projects will only need one menu across all screens. If you need to show a different SideMenu, such as from a modal view controller presented from a previous SideMenu, do the following:
+1. Declare a variable containing your custom `SideMenuManager` instance. You may want it to define it globally and configure it in your app delegate if menus will be used on multiple screens.
+``` swift
+let customSideMenuManager = SideMenuManager()
+```
+2. Setup and display menus with your custom instance the same as you would with the  `SideMenuManager.default` instance.
+3. If using Storyboards, subclass your instance of `UISideMenuNavigationController` and set its `sideMenuManager` property to your custom instance. This must be done before `viewDidLoad` is called:
+``` swift
+class MySideMenuNavigationController: UISideMenuNavigationController {
+
+    let customSideMenuManager = SideMenuManager()
+
+    override func awakeFromNib() {
+        super.awakeFromNib()
+
+        sideMenuManager = customSideMenuManager
+    }
+
+}
+```
+Alternatively, you can set  `sideMenuManager` from the view controller that segues to your UISideMenuNavigationController:
+``` swift
+override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
+    if let sideMenuNavigationController = segue.destination as? UISideMenuNavigationController {
+        sideMenuNavigationController.sideMenuManager = customSideMenuManager
+    }
+}
+```
+*Important: displaying SideMenu instances directly over each other is not supported. Use `menuPushStyle = .subMenu` instead.*
 ## Known Issues
 Don't try to change the status bar appearance when presenting a menu. When used with quick gestures/animations, it causes the presentation animation to not complete properly and locks the UI. This was fixed in iOS 9.3. See [radar 21961293](http://www.openradar.me/21961293) for more information.
