+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make 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 within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+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 opensource@github.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

@@ -10,6 +10,22 @@ This action sets by node environment for use in actions by:
 - registering problem matchers for error output
 - configuring authentication for GPR or npm
 
+# v2-beta
+
+A beta release which adds reliability for pulling node distributions from a cache of node releases is available by referencing the `v2-beta` tag.
+
+```yaml
+steps:
+- uses: actions/checkout@v2
+- uses: actions/setup-node@v2-beta
+  with:
+    node-version: '12'
+```
+
+It will first check the local cache for a semver match.  The hosted images have been updated with the latest of each LTS from v8, v10, v12, and v14. `self-hosted` machines will benefit from the cache as well only downloading once.  It will pull LTS versions from [node-versions releases](https://github.com/actions/node-versions/releases) and on miss or failure, it will fall back to the previous behavior of download directly from [node dist](https://nodejs.org/dist/).
+
+The `node-version` input is optional.  If not supplied, node which is in your PATH will be used.  However, this action will still register problem matchers and support auth features.  So setting up the node environment is still a valid scenario without downloading and caching versions.
+

+Check latest version:  
+> In basic example, without `check-latest` flag, the action tries to resolve version from local cache firstly and download only if it is not found. Local cache on image is updated with a couple of weeks latency.  
+`check-latest` flag forces the action to check if the cached version is the latest one. It reduces latency significantly but it is much more likely to incur version downloading.

-Check latest version:  
-> In basic example, without `check-latest` flag, the action tries to resolve version from local cache firstly and download only if it is not found. Local cache on image is updated with a couple of weeks latency.  
-`check-latest` flag forces the action to check if the cached version is the latest one. It reduces latency significantly but it is much more likely to incur version downloading.
+Check latest version:
+
+In the basic example above, the `check-latest` flag defaults to `false`. When set to `false`, the action tries to first resolve a version of node from the local cache. For information regarding locally cached versions of Node on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments). The local version of Node in cache gets updated every couple of weeks. If unable to find a specific version in the cache, the action will then attempt to download a version of Node. Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific version of Node is always used.
+
+If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a version of Node will then be downloaded. Set `check-latest` to `true` it you want the most up-to-date version of Node to always be used.
+
+> Setting `check-latest` to `true` has performance implications as downloading versions of Node is slower than using cached versions
