+# Twilio SendGrid Community Code of Conduct
+
+The Twilio SendGrid open source community is made up of members from around the globe with a diverse set of skills, personalities, and experiences. It is through these differences that our community experiences successes and continued growth. When you're working with members of the community, we encourage you to follow these guidelines, which help steer our interactions and strive to maintain a positive, successful and growing community. 
+
+### Be Open
+Members of the community are open to collaboration, whether it's on pull requests, code reviews, approvals, issues or otherwise. We're receptive to constructive comments and criticism, as the experiences and skill sets of all members contribute to the whole of our efforts. We're accepting of all who wish to take part in our activities, fostering an environment where anyone can participate, and everyone can make a difference.
+
+### Be Considerate
+Members of the community are considerate of their peers, which include other contributors and users of Twilio SendGrid. We're thoughtful when addressing the efforts of others, keeping in mind that often the labor was completed with the intent of the good of the community. We're attentive in our communications, whether in person or online, and we're tactful when approaching differing views.
+
+### Be Respectful
+Members of the community are respectful. We're respectful of others, their positions, their skills, their commitments and their efforts. We're respectful of the volunteer efforts that permeate the Twilio SendGrid community. We're respectful of the processes outlined in the community, and we work within them. When we disagree, we are courteous in raising our issues.  Overall, we're good to each other. We contribute to this community not because we have to, but because we want to. If we remember that, these guidelines will come naturally.
+
+## Additional Guidance 
+
+### Disclose Potential Conflicts of Interest
+Community discussions often involve interested parties. We expect participants to be aware when they are conflicted due to employment or other projects they are involved in and disclose those interests to other project members. When in doubt, over-disclose. Perceived conflicts of interest are important to address so that the community’s decisions are credible even when unpopular, difficult or favorable to the interests of one group over another.
+
+### Interpretation
+This Code is not exhaustive or complete. It is not a rulebook; it serves to distill our common understanding of a collaborative, shared environment and goals. We expect it to be followed in spirit as much as in the letter.  When in doubt, try to abide by [Twilio SendGrid’s cultural values](https://sendgrid.com/blog/employee-engagement-the-4h-way) defined by our “4H’s”: Happy, Hungry, Humble and Honest.  
+
+### Enforcement
+Most members of the Twilio SendGrid community always comply with this Code, not because of the existence of this Code, but because they have long experience participating in open source communities where the conduct described above is normal and expected. However, failure to observe this Code may be grounds for suspension, reporting the user for abuse or changing permissions for outside contributors.
+
+## If you have concerns about someone’s conduct
+**Initiate Direct Contact** - It is always appropriate to email a community member (if contact information is available), mention that you think their behavior was out of line, and (if necessary) point them to this Code.
+
+**Discuss Publicly** - Discussing publicly is always acceptable. Note, though, that approaching the person directly may be better, as it tends to make them less defensive, and it respects the time of other community members, so you probably want to try direct contact first.
+
+**Contact the Moderators** - You can reach the Twilio SendGrid moderators by emailing dx@sendgrid.com.
+
+## Attribution

+Twilio SendGrid thanks the following, on which it draws for content and inspiration:

-Hello! Thank you for choosing to help contribute to one of the SendGrid open source libraries. There are many ways you can contribute and help is always welcome.  We simply ask that you follow the following contribution policies.
-
-- [CLAs and CCLAs](#cla)
-- [Roadmap & Milestones](#roadmap)
-- [Feature Request](#feature_request)
-- [Submit a Bug Report](#submit_a_bug_report)
-- [Improvements to the Codebase](#improvements_to_the_codebase)
-- [Understanding the Code Base](#understanding_the_codebase)
-- [Testing](#testing)
-- [Style Guidelines & Naming Conventions](#style_guidelines_and_naming_conventions)
-- [Creating a Pull Request](#creating_a_pull_request)
-
-<a name="roadmap"></a>
-We use [Milestones](https://github.com/sendgrid/sendgrid-php/milestones) to help define current roadmaps, please feel free to grab an issue from the current milestone. Please indicate that you have begun work on it to avoid collisions. Once a PR is made, community review, comments, suggestions and additional PRs are welcomed and encouraged.
-
-<a name="cla"></a>
-## CLAs and CCLAs
-
-Before you get started, SendGrid requires that a SendGrid Contributor License Agreement (CLA) be filled out by every contributor to a SendGrid open source project.
-
-Our goal with the CLA is to clarify the rights of our contributors and reduce other risks arising from inappropriate contributions.  The CLA also clarifies the rights SendGrid holds in each contribution and helps to avoid misunderstandings over what rights each contributor is required to grant to SendGrid when making a contribution.  In this way the CLA encourages broad participation by our open source community and helps us build strong open source projects, free from any individual contributor withholding or revoking rights to any contribution.
-
-SendGrid does not merge a pull request made against a SendGrid open source project until that pull request is associated with a signed CLA. Copies of the CLA are available [here](https://gist.github.com/SendGridDX/98b42c0a5d500058357b80278fde3be8#file-sendgrid_cla).
-
-When you create a Pull Request, after a few seconds, a comment will appear with a link to the CLA. Click the link and fill out the brief form and then click the "I agree" button and you are all set. You will not be asked to re-sign the CLA unless we make a change.
-
-There are a few ways to contribute, which we'll enumerate below:
-
-<a name="feature_request"></a>
-## Feature Request
-
-If you'd like to make a feature request, please read this section.
-
-The GitHub issue tracker is the preferred channel for library feature requests, but please respect the following restrictions:
-
-- Please **search for existing issues** in order to ensure we don't have duplicate bugs/feature requests.
-- Please be respectful and considerate of others when commenting on issues
-
-<a name="submit_a_bug_report"></a>
-## Submit a Bug Report
-
-Note: DO NOT include your credentials in ANY code examples, descriptions, or media you make public.
-
-A software bug is a demonstrable issue in the code base. In order for us to diagnose the issue and respond as quickly as possible, please add as much detail as possible into your bug report.
-
-Before you decide to create a new issue, please try the following:
-
-1. Check the Github issues tab if the identified issue has already been reported, if so, please add a +1 to the existing post.
-2. Update to the latest version of this code and check if issue has already been fixed
-3. Copy and fill in the Bug Report Template we have provided below
-
-### Please use our Bug Report Template
-
-In order to make the process easier, we've included a [sample bug report template](https://github.com/sendgrid/sendgrid-php/blob/master/.github/ISSUE_TEMPLATE) (borrowed from [Ghost](https://github.com/TryGhost/Ghost/)). The template uses [GitHub flavored markdown](https://help.github.com/articles/github-flavored-markdown/) for formatting.

-
-<a name="versions"></a>
-## Versions
-
-We follow the MAJOR.MINOR.PATCH versioning scheme as described by [SemVer.org](http://semver.org). Therefore, we recommend that you always pin (or vendor) the particular version you are working with to your code and never auto-update to the latest version. Especially when there is a MAJOR point release, since that is guarenteed to be a breaking change. Changes are documented in the [CHANGELOG](https://github.com/sendgrid/sendgrid-php/blob/master/CHANGELOG.md) and [releases](https://github.com/sendgrid/sendgrid-php/releases) section.
-
-<a name="environment"></a>
-## Environment Variables and Your SendGrid API Key
-
-All of our examples assume you are using [environment variables](https://github.com/sendgrid/sendgrid-php#setup-environment-variables) to hold your SendGrid API key.
-
-If you choose to add your SendGrid API key directly (not recommended):
-
-`$apiKey = getenv('SENDGRID_API_KEY');`
-
-becomes
-

-**This endpoint allows you to remove an IP address from warmup mode.**
-
-SendGrid can automatically warm up dedicated IP addresses by limiting the amount of mail that can be sent through them per hour, with the limit determined by how long the IP address has been in warmup. See the [warmup schedule](https://sendgrid.com/docs/API_Reference/Web_API_v3/IP_Management/ip_warmup_schedule.html) for more details on how SendGrid limits your email traffic for IPs in warmup.
-
-For more general information about warming up IPs, please see our [Classroom](https://sendgrid.com/docs/Classroom/Deliver/Delivery_Introduction/warming_up_ips.html).
-
-### DELETE /ips/warmup/{ip_address}
-
-
-```php
-$ip_address = "test_url_param";
-$response = $sg->client->ips()->warmup()->_($ip_address)->delete();
-echo $response->statusCode();
-echo $response->body();
-print_r($response->headers());
-```
-## Retrieve all IP pools an IP address belongs to
-
-**This endpoint allows you to see which IP pools a particular IP address has been added to.**
-
-The same IP address can be added to multiple IP pools.
-
-A single IP address or a range of IP addresses may be dedicated to an account in order to send email for multiple domains. The reputation of this IP is based on the aggregate performance of all the senders who use it.
-
-### GET /ips/{ip_address}
-
-
-```php
-$ip_address = "test_url_param";
-$response = $sg->client->ips()->_($ip_address)->get();
-echo $response->statusCode();
-echo $response->body();
-print_r($response->headers());

-# WHITELABEL
-
-## Create a domain whitelabel.
-
-**This endpoint allows you to create a whitelabel for one of your domains.**
-
-If you are creating a domain whitelabel that you would like a subuser to use, you have two options:
-1. Use the "username" parameter. This allows you to create a whitelabel on behalf of your subuser. This means the subuser is able to see and modify the created whitelabel.
-2. Use the Association workflow (see Associate Domain section). This allows you to assign a whitelabel created by the parent to a subuser. This means the subuser will default to the assigned whitelabel, but will not be able to see or modify that whitelabel. However, if the subuser creates their own whitelabel it will overwrite the assigned whitelabel.
-
-A domain whitelabel allows you to remove the via or sent on behalf of message that your recipients see when they read your emails. Whitelabeling a domain allows you to replace sendgrid.net with your personal sending domain. You will be required to create a subdomain so that SendGrid can generate the DNS records which you must give to your host provider. If you choose to use Automated Security, SendGrid will provide you with 3 CNAME records. If you turn Automated Security off, you will be given 2 TXT records and 1 MX record.

+Use Docker to easily try out or contribute to the sendgrid-php library. 
+
+This Docker image contains:
+ - PHP 7.1.16
+ - A running instance of [Stoplight.io's Prism](https://stoplight.io/platform/prism/), which lets you try out the Twilio SendGrid API without actually sending email
+ - A mirrored copy of sendgrid-php so that you may develop locally and then run the tests within the Docker container.
+

+* [Contributing](#contributing)
+
+<a name="quick-start"></a>
+# Quick Start
+
+0. Install Composer:
+  - `php -r "readfile('https://getcomposer.org/installer');" | php`
+  - `mv composer.phar /usr/local/bin/composer`
+1. Clone the sendgrid-php repo
+  - `git clone https://github.com/sendgrid/sendgrid-php.git`
+  - `cd sendgrid-php`
+  - `composer install`
+2. [Install Docker](https://docs.docker.com/install/)
+3. [Setup local environment variable SENDGRID_API_KEY](https://github.com/sendgrid/sendgrid-php#setup-environment-variables)
+4. Build Docker image, run Docker container, login to the Docker container
+  - `docker image build --tag="sendgrid/php7" ./docker`
+  - `docker run -itd --name="sendgrid_php7" -v $(pwd):/root/sendgrid-php sendgrid/php7 /bin/bash`
+5. Run the tests within the Docker container
+  - `docker exec -it sendgrid_php7 /bin/bash -c 'cd sendgrid-php/test; ../vendor/bin/phpunit . --filter test*; exec "${SHELL:-sh}"'`
+
+Now you can continue development locally, and run `../vendor/bin/phpunit . --filter test*` inside of the container to test. Replace `test*` with the name of a particular test if you do not wish to run the entire suite of tests.
+
+To clean up the container: `docker stop sendgrid_php7 && docker rm sendgrid_php7`.
+
+Happy Hacking! 
+
+<a name="testing"></a>
+# For Testing the Library (Kick the Tires)
+
+- After step 5 in the QuickStart, within the Docker container: 
+  - `cd ../`
+  - `php sendmail.php` 
+
+<a name="contributing"></a>
+# For Contributors
+
+- Develop per usual locally, but before pushing up to GitHub, you can run the tests locally in the Docker container per step 5 of the quickstart.
+- To run all the tests: `../vendor/bin/phpunit . --filter test*`
+- To run an individual test: `../vendor/bin/phpunit . --filter [Name of Test]`
