+# Release
+
+Releases are mostly automated using
+[release-it](https://github.com/release-it/release-it/) and
+[lerna-changelog](https://github.com/lerna/lerna-changelog/).
+
+
+## Preparation
+
+Since the majority of the actual release process is automated, the primary
+remaining task prior to releasing is confirming that all pull requests that
+have been merged since the last release have been labeled with the appropriate
+`lerna-changelog` labels and the titles have been updated to ensure they
+represent something that would make sense to our users. Some great information
+on why this is important can be found at
+[keepachangelog.com](https://keepachangelog.com/en/1.0.0/), but the overall
+guiding principles here is that changelogs are for humans, not machines.
+
+When reviewing merged PR's the labels to be used are:
+
+* breaking - Used when the PR is considered a breaking change.
+* enhancement - Used when the PR adds a new feature or enhancement.
+* bug - Used when the PR fixes a bug included in a previous release.
+* documentation - Used when the PR adds or updates documentation.
+* internal - Used for internal changes that still require a mention in the
+  changelog/release notes.
+
+
+## Release
+
+Once the prep work is completed, the actual release is straight forward:
+
+```
+yarn install
+yarn release
+```
+
+The `release` script leverages
+[release-it](https://github.com/release-it/release-it/) to do the mechanical
+release process. It will prompt you through the process of choosing the version
+number, tagging, pushing the tag and commits, etc.
