+# 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 [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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [https://contributor-covenant.org/version/1/4][version]

+# Aws::Embedded::Metrics for Ruby [![Actions Status](https://github.com/customink/aws-embedded-metrics-customink/workflows/CI/badge.svg)](https://github.com/customink/aws-embedded-metrics-customink/actions)
+
+⚠️ Bare minimum code to explore [Amazon CloudWatch Embedded Metrics](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format.html) with Ruby. Any and all help welcome to raise the quality of our implementation.
+
+#### Inspiration
+
+Pulled from these two projects using the [Embedded Metric Format Specification](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format_Manual.html) as a reference guide.
+
+* Node: https://github.com/awslabs/aws-embedded-metrics-node
+* Python: https://github.com/awslabs/aws-embedded-metrics-python
+
+However, unlike these projects, we differ in the following ways. Again, contributions are very much welcome if you want to see more or change this.
+
+* Initial focus on Lambda. No other sinks.
+* As such, no default Dimensions or Configuraiton for:
+ - `LogGroupName`
+ - `LogStreamName`
+ - `ServiceName`
+ - `ServiceType`
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'aws-embedded-metrics-customink'
+```
+## Usage
+
+Simple configuration.
+
+```ruby
+Aws::Embedded::Metrics.configure do |c|
+ c.namespace = 'MyApplication'
+end
+```
+
+Usage is in a scope block. All metrics are flushed afterward
+
+```ruby
+Aws::Embedded::Metrics.logger do |metrics|
+ metrics.put_dimension 'SomeDimension', 'SomeDimensionValue'
+ metrics.set_property 'EventKey', 'some/s3/path'
+ metrics.put_metric 'Processor', 232, 'Milliseconds'
+ metrics.put_metric 'Total', 4008, 'Milliseconds'
+end
+```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `bin/test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+
+To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
+
