+# 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, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, 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 [email protected]. 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.

+We want to make contributing to this project as easy and transparent as possible, whether it's:
+
+- Reporting a bug
+- Discussing the current state of the code
+- Submitting a fix
+- Proposing new features

+
+The following is a set of guidelines for contributing to Xero and its projects, which are hosted in the [XeroAPI Organization](https://github.com/XeroAPI) on GitHub. These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.

+## Code of Conduct
+Please note that this project is released with a [Contributor Code of Conduct](https://github.com/XeroAPI/xero-php-oauth2-app/blob/master/CODE_OF_CONDUCT.md). By participating in this project you agree to abide by its terms.
+
+## I don't want to read this whole thing I just have a question!!!
+
+> **Note:** Please don't file an issue to ask a question. You'll get faster results by using the resources below.
+
+We have an official [message board](https://community.xero.com/developer) where Xero API support and the community chimes in with helpful advice if you have questions.
+
+* [API Documentation](https://developer.xero.com/documentation/)
+* [Xero FAQ](https://developer.xero.com/faq)
+* [Community, the official Xero message board](https://community.xero.com/developer)
+* [Stackoverflow - Xero related](https://stackoverflow.com/questions/tagged/xero-api?sort=Newest)
+* [Submit requests for support](https://developer.xero.com/contact-xero-developer-platform-support/) to our API Support team.
+
+# How Can I Contribute?
+
+You can contribute by reporting bugs, suggesting enhancements, improving documentation i.e. [README](https://github.com/XeroAPI/xero-php-oauth2-app/blob/master/README.md) or submitting a pull request.
+
+## Reporting Bugs
+
+Bugs are tracked as issues in this repository.
+
+Before opening a new issue:
+* **check [the README](https://github.com/XeroAPI/xero-php-oauth2-app/blob/master/README.md)** to see if the behavior you observed might be expected and if configuration options are available to provide you with the desired behavior.
+
+* **perform a cursory search** to see if there's [an existing issue](https://github.com/XeroAPI/xero-php-oauth2-app/issues) covering your feedback. If there is one and the issue is still open, **add a :+1: reaction** on the issue to express interest in the issue being resolved. That will help the team gauge interest without the noise of comments which trigger notifications to all watchers. Comments should be used only if you have new and useful information to share.
+
+### Write bug reports with detail, background, and sample code
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can. 
+- What you expected would happen
+- What actually happens
+- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
+
+## Suggesting Enhancements
+
+When opening an issue for a feature request:
+* **use a clear and descriptive title** for the issue to identify the problem.
+* **include as many details as possible in the body**. Explain your use-case, the problems you're hitting and the solutions you'd like to see to address those problems.
+
+## Pull requests
+
+We welcome your feedback and pull requests. Be aware some code is generated and pull requests may not be the best solution -  see below.
+
+### Submit a pull request
+
+1. Fork and clone the repository
+1. Create a new branch: `git checkout -b my-branch-name`
+1. Make your change, add tests if needed
+1. Make sure the tests pass on your machine: `mvn test`
+1. Push to your fork and submit a pull request
+1. Pat your self on the back and wait for your pull request to be reviewed and merged.
+
+Here are a few things you can do that will increase the likelihood of your pull request being accepted:
+
+- Write tests.
+- Keep your change as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as separate pull requests.
+- Write a [good commit message](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).

+
+This is a project is for use with xero-php-oauth2 SDK. This app demonstrates the functionality of Xero accounting API endpoints and their related actions. 
+
+You'll be able to connect to a Xero Organisation, make real API calls. The code used to make each API call will be displayed along with the results returned from Xero's API.
+
+## Getting Started
+To run locally, you'll need a local web server with PHP support.  
+* MAMP is a good option [Download MAMP](https://www.mamp.info/en/downloads/) 
+
+Follow these steps
+* Clone this repo into your webroot. Look in your MAMP folder for `htdocs`
+* Launch a terminal app and change to the newly cloned folder `xero-php-oauth2-app`
+* Download dependencies with Composer.
+
+`composer init`
+
+New to Composer? You'll want to [install Composer](https://getcomposer.org/doc/00-intro.md)
+
+## Create a Xero App

+
+* authorization.php
+* callback.php
+* get.php.
+
+```php
+	$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+        'clientId'                => '__YOUR_CLIENT_ID__',   
+        'clientSecret'            => '__YOUR_CLIENT_SECRET__',
+        'redirectUri'             => 'http://localhost:8888/xero-php-oauth2-app/callback.php',
+	    'urlAuthorize'            => 'https://login.xero.com/identity/connect/authorize',
