Document the lifecycle status and corresponding level of support of the library. Examples include:

• Incubating: no support expected
• Stable: SLOs in place to handle issues
• Maintenance: only bugs will be addressed
• Deprecated: critical bugs might be addressed for a limited period of time
• Archived: no work is expected

Clearly state the API and behavioral stability clients can expect from the library. For example you might say:

• This API is stable and suitable for production use, aside from packages, classes, and methods marked internal or experimental.
• This API is beta and will not experience an API or behavior breaking change unless a bug or design flaw is uncovered.
• This API is in development. Anything may change at any time. Stable products should not depend on it.

Provide and document a feedback mechanism. For example:

• File an issue at https://github.com/...
• Send email to dev@fooproject.example.com
