+# Conventional Commits
+
+The commit message should be structured as follows:
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+The commit contains the following structural elements, to communicate intent to the consumers of your library:
+
+1. fix: a commit of the type fix patches a bug in your codebase (this correlates with [PATCH](https://semver.org/#summary) in Semantic Versioning).
+1. feat: a commit of the type feat introduces a new feature to the codebase (this correlates with [MINOR](https://semver.org/#summary) in Semantic Versioning).
+1. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with [MAJOR](https://semver.org/#summary) in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.
+1. types other than fix: and feat: are allowed, for example [@commitlint/config-conventional](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional) (based on the [the Angular convention](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#-commit-message-guidelines)) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
+1. footers other than BREAKING CHANGE: <description> may be provided and follow a convention similar to [git trailer format](https://git-scm.com/docs/git-interpret-trailers).
+
+Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE). A scope may be provided to a commit’s type, to provide additional contextual information and is contained within parenthesis, e.g., feat(parser): add ability to parse arrays.
+
+### Specification
+The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
+
+1. Commits MUST be prefixed with a type, which consists of a noun, feat, fix, etc., followed by the OPTIONAL scope, OPTIONAL !, and REQUIRED terminal colon and space.
+1. The type feat MUST be used when a commit adds a new feature to your application or library.
+1. The type fix MUST be used when a commit represents a bug fix for your application.
+1. A scope MAY be provided after a type. A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., fix(parser):
+1. A description MUST immediately follow the colon and space after the type/scope prefix. The description is a short summary of the code changes, e.g., fix: array parsing issue when multiple spaces were contained in string.
+1. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes. The body MUST begin one blank line after the description.
+1. A commit body is free-form and MAY consist of any number of newline separated paragraphs.
+1. One or more footers MAY be provided one blank line after the body. Each footer MUST consist of a word token, followed by either a :<space> or <space># separator, followed by a string value (this is inspired by the [git trailer convention](https://git-scm.com/docs/git-interpret-trailers).
+1. A footer’s token MUST use - in place of whitespace characters, e.g., Acked-by (this helps differentiate the footer section from a multi-paragraph body). An exception is made for BREAKING CHANGE, which MAY also be used as a token.
+1. A footer’s value MAY contain spaces and newlines, and parsing MUST terminate when the next valid footer token/separator pair is observed.
+1. Breaking changes MUST be indicated in the type/scope prefix of a commit, or as an entry in the footer.
+1. If included as a footer, a breaking change MUST consist of the uppercase text BREAKING CHANGE, followed by a colon, space, and description, e.g., BREAKING CHANGE: environment variables now take precedence over config files.
+1. If included in the type/scope prefix, breaking changes MUST be indicated by a ! immediately before the :. If ! is used, BREAKING CHANGE: MAY be omitted from the footer section, and the commit description SHALL be used to describe the breaking change.
+1. Types other than feat and fix MAY be used in your commit messages, e.g., docs: updated ref docs.
+1. The units of information that make up Conventional Commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase.
+BREAKING-CHANGE MUST be synonymous with BREAKING CHANGE, when used as a token in a footer.
