# Legacy Documentation
This documentation platform covers only supported versions of the Umbraco CMS, excluding version 8. If you use an unsupported version, you need to go elsewhere.
[Learn more about how long each major version of Umbraco is supported.](https://umbraco.com/products/knowledge-center/long-term-support-and-end-of-life/)
## [Legacy versions on GitHub](https://github.com/umbraco/UmbracoDocs/tree/umbraco-eol-versions)
When a major version of Umbraco CMS goes End of Life (EOL), the documentation for this version will be unpublished 3 months later.
The documentation for all EOL versions will continue to be available on the [UmbracoDocs GitHub repository](https://github.com/umbraco/UmbracoDocs/tree/umbraco-eol-versions).
## Our Umbraco
The documentation for Umbraco 7 and 8 lives on [our.umbraco.com](https://our.umbraco.com/documentation/).
