+# 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 open-source@twilio.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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

 # Send an SMS during a phone call. Powered by Twilio and PHP/Slim
 
+![](https://github.com/TwilioDevEd/send-sms-during-inbound-calls-php/workflows/Composer/badge.svg)
+
 > We are currently in the process of updating this sample template. If you are encountering any issues with the sample, please open an issue at [github.com/twilio-labs/code-exchange/issues](https://github.com/twilio-labs/code-exchange/issues) and we'll try to help you.
 
+## About
+
 Learn how to send an SMS to someone who's called your Twilio phone number while they're on the call.
 
 This small sample application will say a short message to an inbound caller and, at the same time, send them an SMS.

+
+## Set up
+
+### Requirements
+
+- [PHP >= 7.2.5](https://www.php.net/) and [composer](https://getcomposer.org/)
+- A Twilio account - [sign up](https://www.twilio.com/try-twilio)
+
+### Twilio Account Settings
 
-## Local Development
+This application should give you a ready-made starting point for writing your own application.
+Before we begin, we need to collect all the config values we need to run the application:
 
-This project is built using the [Slim](https://www.slimframework.com/) web framework, PHP 7, and the [Twilio PHP Helper Library](https://www.twilio.com/docs/libraries/php).
+| Config&nbsp;Value | Description                                                                                                                                                  |
+| :---------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Account&nbsp;Sid  | Your primary Twilio account identifier - find this [in the Console](https://www.twilio.com/console).                                                         |
+| Auth&nbsp;Token   | Used to authenticate - [just like the above, you'll find this here](https://www.twilio.com/console).                                                         |
 
-1. First clone this repository and `cd` into it.
+### Local development
 
-   ```bash
-   $ git clone https://github.com/TwilioDevEd/send-sms-during-inbound-calls-php.git
-   $ cd send-sms-during-inbound-calls-php
-   ```
+After the above requirements have been met:
 
-1. Install the dependencies.
+1. Clone this repository and `cd` into it
 
     ```bash
-    $ composer install
+    git clone git@github.com:TwilioDevEd/send-sms-during-inbound-calls-php.git
+    cd send-sms-during-inbound-calls-php
     ```
 
-1. Create an environment file (`.env`) and define your Twilio Account SID and Auth Token. Both of these can be found in your [Twilio console](https://www.twilio.com/console).
+1. Install PHP dependencies
 
-   ```bash
-   export ACCOUNT_SID=ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-   export AUTH_TOKEN=your_auth_token
-   ```
+    ```bash
+    make install
+    ```
 
-1. Load the created file into your environment.
+1. Set your environment variables
 
     ```bash
-    source .env
+    cp .env.example .env
     ```
 
-1. Start the server.
+    See [Twilio Account Settings](#twilio-account-settings) to locate the necessary environment variables.
+
+1. Run the application
 
     ```bash
-    $ php -S localhost:8080
+    make serve
     ```
 
 1. Expose the application to the wider Internet using [ngrok](https://ngrok.com/).
 
+> [Learn 6 awesome reasons why to use ngrok](https://www.twilio.com/blog/2015/09/6-awesome-reasons-to-use-ngrok-when-testing-webhooks.html).
+
     ```bash
-    $ ngrok http 8080 -host-header="localhost:8080"
+    ngrok http 8000 -host-header="localhost:8000"
     ```
 
 1. Configure Twilio to call your webhooks
 
-  You will need to configure Twilio to call your application when calls are
-  received in your [*Twilio Number*](https://www.twilio.com/user/account/messaging/phone-numbers).
-  The voice url should look something like this:
+  You will need to configure Twilio to call your application when calls are received in your [*Twilio Number*](https://www.twilio.com/user/account/messaging/phone-numbers). The voice url with `POST` method should look something like this:
 
   ```
   https://<your-ngrok-subdomain>.ngrok.io/answer
   ```
 
+  That's it!
+
+### Docker
+
+If you have [Docker](https://www.docker.com/) already installed on your machine, you can use our `docker-compose.yml` to setup your project.
+
+1. Make sure you have the project cloned.
+2. Setup the `.env` file as outlined in the [Local Development](#local-development) steps.
+3. Run `docker-compose up`.
+4. Follow the steps in [Local Development](#local-development) on how to expose your port to Twilio using a tool like [ngrok](https://ngrok.com/) and configure the remaining parts of your application.
+
+### Unit and Integration Tests
+
+You can run the Unit and Feature tests locally by typing:
+```bash
+vendor/bin/phpunit tests
+```
+
+### Cloud deployment
+
+Additionally to trying out this application locally, you can deploy it to a variety of host services. Here is a small selection of them.
+
+Please be aware that some of these might charge you for the usage or might make the source code for this application visible to the public. When in doubt research the respective hosting service first.
