-### Support Policy
+### Go Support Policy
 
-Datadog APM for Go is built upon dependencies defined in specific versions of the host operating system, Go releases, and the Datadog Agent/API. For Go the two latest releases are [GA](#support-ga) supported and the version before that is in [Maintenance](#support-maintenance). We do make efforts to support older releases, but generally these releases are considered [Legacy](#support-legacy). This library only officially supports [first class ports](https://github.com/golang/go/wiki/PortingPolicy#first-class-ports) of Go.

-### Supported Versions
-<!-- NOTE: When updating the below section ensure you update the minimum supported version listed in the public docs here: https://docs.datadoghq.com/tracing/setup_overview/setup/go/?tab=containers#compatibility-requirements -->
-| **Go Version** | **Support level**                   |

-| 1.20           | [Maintenance](#support-maintenance) |

-* Datadog's Trace Agent >= 5.21.1
-

-#### Package Versioning
-
-A **Minor** version change will be released whenever a new version of Go is released. At that time the newest version of Go is added to [GA](#support-ga), the second oldest supported version moved to [Maintenance](#support-maintenance) and the oldest previously supported version dropped to [Legacy](#support-legacy).
-**For example**:
-For a dd-trace-go version 1.37.*
-
-| Go Version | Support                             |
-|------------|-------------------------------------|
-| 1.18       | [GA](#support-ga)                   |
-| 1.17       | [GA](#support-ga)                   |
-| 1.16       | [Maintenance](#support-maintenance) |
-
-Then after Go 1.19 is released there will be a new dd-trace-go version 1.38.0 with support:
-
-| Go Version | Support                             |
