+# JSQMessagesViewController 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 **jesse.squires.developer [at] gmail [dot] com**. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and 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.

+# Contributor Onboarding
+
+*Contributor onboarding guide for JSQMessagesViewController*
+
+This guide is intended to bring new core contributors up-to-speed on the project, organization, expectations, and best practices.
+
+-------------------------
+
+## Introduction
+
+Welcome! :smile: If you are reading this, then you are (or are about to be) a core contributor! :tada: The goal of this document is to cover everything you need to know about helping to maintain this project. If you are not familiar with the code, the docs, the demo project, and everything else in the repo, then that should be your first step. Otherwise, continue on!
+
+## Getting push access
+
+Being a **contributor** means submitting pull requests, opening issues, etc. Being a **core contributor** means getting push access and other permissions.
+
+We love freely giving push access to great contributors, and always err on trusting contributors with this responsibility. However, before granting you push access we would like to see a few things:
+
+- An interest and dedication to the project
+- Helping to triage issues, review pull requests, and diagnose bugs
+- Submitting a couple great pull requests
+
+We really prefer to grant push access to contributors who have a decent amount of time to share each week or month. If you cannot be extremely active on the project — that's ok! You can still be an :sparkles: awesome contributor :sparkles: without getting push access! 
+
+The rationale behind all of this is that we do not want to accumulate a *huge* list of **core contributors** that are *not* regularly active.
+
+Remember, *your time* is *your time* — there is absolutely no pressure on you to spend a lot of time on this project, although it is greatly appreciated! :smile:
+
+> **Note:** the rest of this document applies to both **contributors** and **core contributors**, but there are some details that would require having push access.
+
+## Core team
+
+### Project lead
+
+Jesse Squires ([**@jessesquires**](https://github.com/jessesquires)) serves as the lead for `JSQMessagesViewController`.
+
+Responsibilities include:
+- Managing releases and CocoaPods distributions
+- Merging code into `master`
+- Overall guidance on design, architecture, and implementation
+- Strategic direction for the library
+- Onboarding new core contributors
+- Everything under **Core Contributors** :smile:
+- Anything not covered by **Core Contributors** :smile:
+
+As core contributors grow and take on more repsonsibility, they can become a lead.
+
+### Core contributors
+
+Core contributors have push access and are responsible for:
+
+- Bug fixes
+- New features
+- Triaging issues (managing, organizing)
+- Reviewing pull requests
+- Answering questions from the community on [issues](https://github.com/jessesquires/JSQMessagesViewController/issues?utf8=✓&q=is%3Aissue+label%3A%22questions+%26+help%22+) and [StackOverflow](http://stackoverflow.com/questions/tagged/jsqmessagesviewcontroller)
+- Documentation
+
+Current core contributors:
+- Harlan Haskans ([**@harlanhaskins**](https://github.com/harlanhaskins))
+- Eli Burke ([**@eliburke**](https://github.com/eliburke))
+
+## Pushing code
+
+Although you have permissions to push code directly to `develop` as a core contributor, we ask that you *always* submit a pull request for code changes. After a code review and approval, you may merge your diff. For minor changes, like formatting or typos, pushing directly to `develop` is acceptable. 
+
+Always merge work to `develop` unless otherwise specified. The project lead will manage the `master` branch.
+
+For now, Jesse ([**@jessesquires**](https://github.com/jessesquires)) should provide the final approval for *all* pull requests. However, as core contributors grow and establish themselves in the project, they can take on this responsibility as well.
+
+## Project managment
+
+### General guidelines
+
+Above all, abide by our [code of conduct](https://github.com/jessesquires/JSQMessagesViewController/blob/develop/.github/CONDUCT.md) at all times. Be welcoming, kind, and inclusive.
+
+Often, users do not follow our [contributing guidelines](https://github.com/jessesquires/JSQMessagesViewController/blob/develop/.github/CONTRIBUTING.md), fail to complete the [issue template](https://github.com/jessesquires/JSQMessagesViewController/blob/develop/.github/ISSUE_TEMPLATE.md), or fail to complete the [pull request template](https://github.com/jessesquires/JSQMessagesViewController/blob/develop/.github/PULL_REQUEST_TEMPLATE.md). This is frustrating, but the best response is to kindly remind and encourage them to follow the correct procedures next time.
+
+When first responding to a newly opened issue or pull request, *always* thank the contributor and add some sweet emoji. Any positive emoji will work. (:+1:, :smile:, :sunglasses:, etc.) Choose your favorite.
+
+> Thanks **@jessesquires**! :smile_cat:
+
+Then continue on with the rest of your comment. There will be times where we simply cannot accept a patch for various reasons. In this case, kindly explain why it is not the right approach for the library, thank them for their time and effort, and encourage them to keep contributing.
+
+In any situation, when in doubt, tag the project lead in a comment to get feedback.
+
+### Development
+
+- All work for minor and patch releases should happen on `develop`. For example, release 7.x.x.
+- All work for major releases should happen on a release branch. For example, `release_8.0`.
+- The project lead will manage the `master` branch.
+
+For core contributors, always assign issues or pull requests to the appropriate team member. If you are working on an issue, assign it to yourself. If you would like someone to review a pull request, assign it to them.
+
+### Managing issues
+
+- Always add the appropriate label(s). There may be more than one.
+- Assign to a release milestone, if applicable.
+- Ask for more information from the user, if needed.
+- Verify bugs. Leave comments on your findings as necessary.
+- If it's a duplicate, label and close.
+- Follow the general guidelines above.
+
+##### Special labels
+
+- [`needs review`](https://github.com/jessesquires/JSQMessagesViewController/issues?q=is%3Aissue+label%3A%22needs+review%22): These issues need to be triaged and confirmed. They are typically bugs or pull requests, but do not have to be. Once verified, `needs review` should be removed and any other appropriate labels should be added.
+- [`new release roadmap`](https://github.com/jessesquires/JSQMessagesViewController/issues?utf8=✓&q=is%3Aissue+label%3A%22new+release+roadmap%22+): For communicating new releases to the community.
+- [`in-progress`](https://github.com/jessesquires/JSQMessagesViewController/issues?q=is%3Aissue+label%3Ain-progress): Specifies a task that is currently being worked on. Remove this label after closing a task.
+- [`duplicate`](https://github.com/jessesquires/JSQMessagesViewController/issues?utf8=✓&q=label%3Aduplicate+): For duplicate isses. When closing an issue as a duplicate be sure to leave a comment with the original issue number. *"Closing as duplicate of #6."*
+- [`questions & help`](https://github.com/jessesquires/JSQMessagesViewController/issues?q=is%3Aissue+label%3A%22questions+%26+help%22): For community questions and help. Note that we are trying to refer questions to [StackOverflow](http://stackoverflow.com/questions/tagged/jsqmessagesviewcontroller) instead.
+
+### Managing pull requests
+
+- Review the code for correctness, performance, style, etc. Leave comments as needed.
+- Always add the appropriate label(s). There may be more than one.
+- Assign to a release milestone, if applicable.
+- Follow the general guidelines above.
+- If you think it's ready to go, tag the project lead to get the final :+1:
+
+### Managing releases
+
+All releases are organized using [milestones](https://github.com/jessesquires/JSQMessagesViewController/milestones). Use these to prioritize work and figure out what's next.
+
+Issues and pull requests included in the next milestone release should be the highest priorty. Once a milestone is 100% complete, the project lead will merge `develop` or other release branches into `master`. The project lead will close the milestone, tag the release, and submit to CocoaPods.
+
+### Managing documentation
+
+Having high quality documentation and 100% coverage has a significant impact on the project's success. 
+
+Always add new docs for new public APIs and keep them up-to-date. Use existing docs and Apple's docs for Cocoa as guidelines for writing great documentation.

+# FAQ
+
+*Frequently asked questions for JSQMessagesViewController.* 
+
+Contributions are welcome! Please submit a [pull request](https://github.com/jessesquires/JSQMessagesViewController/compare).
+
+------------------------------------
+
+## For 7.x.x
+
+#### Using `UITabBar` ?
+
+Is the library compatible with `UITabBarController` and `UITabBar`? Yes and no. For the history on this issue, see [#179](https://github.com/jessesquires/JSQMessagesViewController/issues/179) and [#94](https://github.com/jessesquires/JSQMessagesViewController/issues/94). This seems to be the best workaround:
+
+````objective-c
+- (void)viewDidLoad
+{
+    [super viewDidLoad];
+    self.edgesForExtendedLayout = UIRectEdgeNone;
+}
+````
+
+#### *Springy bubbles?*
+
+:warning: Note: this feature is still experimental.
+
+````objective-c
+- (void)viewDidAppear:(BOOL)animated
+{
+    [super viewDidAppear:animated];
+    self.collectionView.collectionViewLayout.springinessEnabled = YES;
+}
+````
+
+#### *Remove avatars?*
+````objective-c
+- (void)viewDidLoad
+{
+    [super viewDidLoad];
+    self.collectionView.collectionViewLayout.incomingAvatarViewSize = CGSizeZero;
+    self.collectionView.collectionViewLayout.outgoingAvatarViewSize = CGSizeZero;
+}
+
+- (id<JSQMessageAvatarImageDataSource>)collectionView:(JSQMessagesCollectionView *)collectionView avatarImageDataForItemAtIndexPath:(NSIndexPath *)indexPath
+{
+    return nil;
+}
+````
+
+#### *Need customize your collection view cells?*
+
+There are 2 approaches to this, which one you choose depends on your needs.
+
+1. Customize appearance and behavior of existing cells. (Easy)
+2. Provide your own completely custom cell prototypes. (Hard)
+
+> Also see [previous issues](https://github.com/jessesquires/JSQMessagesViewController/issues?utf8=✓&q=custom+cell+in%3Atitle).
+
+##### (1) Customizing existing cells
+
+If you only need to make minor changes to the existing cells (colors, data detectors, etc.), then you simply need to override the following method. You have access to all properties on the cell. ([docs](http://cocoadocs.org/docsets/JSQMessagesViewController/7.2.0/Classes/JSQMessagesCollectionViewCell.html))
+
+````objective-c
+- (UICollectionViewCell *)collectionView:(JSQMessagesCollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
+{
+    JSQMessagesCollectionViewCell *cell = (JSQMessagesCollectionViewCell *)[super collectionView:collectionView cellForItemAtIndexPath:indexPath];
+    
+    // Customize the shit out of this cell
+    // See the docs for JSQMessagesCollectionViewCell
+    
+    return cell;
+}
+````
+
+##### (2) Providing your own cell prototypes
+
+This approach is more involved, but gives you greater flexibility. If you need to add or modify subviews of the cell, use this approach. ([docs](http://cocoadocs.org/docsets/JSQMessagesViewController/7.2.0/Classes/JSQMessagesViewController.html))
+
+1. You need to provide your own cell subclasses, similar to the library's `JSQMessagesCollectionViewCell`, `JSQMessagesCollectionViewCellIncoming`, `JSQMessagesCollectionViewCellOutgoing`.
+2. On your `JSQMessagesViewController` subclass, set the following properties according to your classes:
+    - `outgoingCellIdentifier`
+    - `outgoingMediaCellIdentifier`
+    - `incomingCellIdentifier`
+    - `incomingMediaCellIdentifier`
+3. Register your cell classes/nibs with the collection view and the identifiers above
+4. Override `-collectionView: cellForItemAtIndexPath:`. Do not call `super`. Since you are providing your own cells, calling `super` will perform a bunch of unnecessary work.
+5. (Optional) For your model objects, implement `JSQMessageData` or subclass `JSQMessage` and extend to your needs.
+
+#### *Customize your toolbar buttons?*
+````objective-c
+- (void)viewDidLoad
+{
+    [super viewDidLoad];
+    
+    // This button will call the `didPressAccessoryButton:` selector on your JSQMessagesViewController subclass
+    self.inputToolbar.contentView.leftBarButtonItem = /* custom button or nil to remove */
+    
+    // This button will call the `didPressSendButton:` selector on your JSQMessagesViewController subclass
+    self.inputToolbar.contentView.rightBarButtonItem = /* custom button or nil to remove */
+    
+    // Swap buttons, move send button to the LEFT side and the attachment button to the RIGHT
+    // For RTL language support
+    self.inputToolbar.contentView.leftBarButtonItem = [JSQMessagesToolbarButtonFactory defaultSendButtonItem];
+    self.inputToolbar.contentView.rightBarButtonItem = [JSQMessagesToolbarButtonFactory defaultAccessoryButtonItem];
+    
+    // The library will call the correct selector for each button, based on this value
+    self.inputToolbar.sendButtonOnRight = NO;
+}
+````

+# Getting Started
+
+*Getting started guide for JSQMessagesViewController*
+
+-----------------------------
+
+## For versions 6.x and 7.x
+
+````objective-c
+#import <JSQMessagesViewController/JSQMessages.h>    // import all the things
+````
+
+* **Tutorials and blogs**
+  * Read the [blog post](http://www.jessesquires.com/introducing-jsqmessagesvc-6-0/) about the 6.0 release!
+  * Ray Wenderlich has a [great tutorial](http://www.raywenderlich.com/122148/firebase-tutorial-real-time-chat), written by [David East](https://twitter.com/_davideast). (For 7.x releases)
+
+* **Demo Project**
+  * There's a sweet demo project: `JSQMessages.xcworkspace`.
+    * Run `pod install` first.
+  * Swift Example can be found in the SwiftExample folder just open the `SwiftExample.xcworkspace`.
+    * Run `pod install` first.
+  * [Firebase](https://www.firebase.com) also has a sweet [demo project](https://github.com/firebase/ios-swift-chat-example), and it's in Swift!
+  
+
+* **Message Model**
+  * Your message model objects should conform to the `JSQMessageData` protocol.
+  * However, you may use the provided `JSQMessage` class.
+
+* **Media Attachment Model**
+  * Your media attachment model objects should conform to the `JSQMessageMediaData` protocol.
+  * However, you may use the provided classes: `JSQPhotoMediaItem`, `JSQLocationMediaItem`, `JSQVideoMediaItem`.
+  * Creating your own custom media items is easy! Simply follow the pattern used by the built-in media types.
+  * Also see `JSQMessagesMediaViewBubbleImageMasker` for masking your custom media views as message bubbles.
+
+* **Avatar Model**
+  * Your avatar model objects should conform to the `JSQMessageAvatarImageDataSource` protocol.
+  * However, you may use the provided `JSQMessagesAvatarImage` class.
+  * Also see `JSQMessagesAvatarImageFactory` for easily generating custom avatars.
+
+* **Message Bubble Model**
+  * Your message bubble model objects should conform to the `JSQMessageBubbleImageDataSource` protocol.
+  * However, you may use the provided `JSQMessagesBubbleImage` class.
+  * Also see `JSQMessagesBubbleImageFactory` and `UIImage+JSQMessages.h` for easily generating custom bubbles.
+
+* **View Controller**
+  * Subclass `JSQMessagesViewController`.
+  * Implement the required methods in the `JSQMessagesCollectionViewDataSource` protocol.
+  * Implement the required methods in the `JSQMessagesCollectionViewDelegateFlowLayout` protocol.
+  * Set your `senderId` and `senderDisplayName`. These properties correspond to the methods found in `JSQMessageData` and determine which messages are incoming or outgoing.
+
+* **Customizing**
+  * The demo project is well-commented. Please use this as a guide.
