+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible 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.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders 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, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at jared@jaredwhite.com. All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior,  harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.
+

+# Inclusive
+
+Compose globally-scoped Ruby modules into local packages. This makes it easy to access utility methods (aka functions) without having to type lengthy namespaces or remember which modules provide with functions at each call site (or alternatively include modules in your classes which pollute the method space).
+
+## Installation
+
+Install the gem and add to the application's Gemfile by executing:
+
+    $ bundle add inclusive
+
+If bundler is not being used to manage dependencies, install the gem by executing:
+
+    $ gem install inclusive
+
+## Usage
+
+To start with, you can write your "package" (aka a standard Ruby module) containing a set of discrete functions. It's recommended you namespace your packages within higher-level modules.
+
+```ruby
+module MyOrg
+  module MyPackages
+    module WorkHardAtIt
+      def just_do_it = puts "Don't let your dreams be dreams"
+    end
+  end
+end
+```
+
+Then in any standard Ruby class, you can include the `Inclusive` module and use the `packages` class helper to "import" the package:
+
+```ruby
+require "inclusive"
+# require the file(s) containing your package(s)
+
+class GetToThePoint
+  include Inclusive
+
+  packages def work_hard = [MyOrg::MyPackages::WorkHardAtIt]
+
+  def nothing_is_impossible
+    work_hard.just_do_it # this will print out the motivational speech
+  end
+end
+```
+
+The import syntax is an array because you can import multiple packages. The imported packages will "compose" together, meaning the methods from the various package modules will all be available simultaneously.
+
+In addition to creating instance methods using the `packages` class helper, you can use the `packages` method inline:
+
+```ruby
+def some_method
+  my_math = packages[MyOrg::Math]
+
+  my_math.multiply_by_100(5)
+end
+```
+
+This approach isn't recommended unless you're in a context where using the class helper is impossible, such as a template (ERB, etc.) or a block which is executed by a framework. You can also call the `packages` method directly on the `Inclusive` module:
+
+```ruby
+my_math = Inclusive.packages(MyOrg::Math)
+```
+
+If you want to be able to call a package method directly on its own module, you can extend your module and use the `public_function` helper:
+
+```ruby
+module Packages
+  module MyPackage
+    extend Inclusive::Public
+
+    def some_method
+      # code
+    end
+
+    public_function :some_method
+  end
+end
+```
+
+Now in addition to using package imports via Inclusive, you can call the module method directly:
+
+```ruby
+Packages::MyPackage.some_method
+```
+
+This is only recommended if you need to mantain an existing module's legacy behavior in a codebase while incrementally adopting Inclusive.
+
+### Packages Are Duplicated
+
+One of the aspects of Inclusive which make it more useful than merely using standard Ruby modules is each imported package is actually a cloned module. This means a module can actually contain internal state, much like an object:
+
+```ruby
+module Packages
+  module Ownership
+    attr_accessor :owner
+
+    def owner_classname
+      owner.class.name
+    end
+  end
+end
+
+class SomeObject
+  def try_out_ownership
+    ownership = packages[Package::Ownership].tap { _1.owner = self }
+
+    puts ownership.owner_classname # this will be `SomeObject`
+  end
+end
+
+class SomeOtherObject
+  def try_out_ownership
+    ownership = packages[Package::Ownership].tap { _1.owner = self }
+
+    puts ownership.owner_classname # this will be `SomeOtherObject`
+  end
+end
+```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `bin/rake 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 `bin/rake install`. To release a new version, update the version number in `version.rb`, and then run `bin/rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
