+## Donations
+
+Donations of preexisting code fall into two broad categories:
+* **Small donations:** Some donations only amount to a single PR and should
+  usually just be contributed as such
+* **Large or complex donations:** Other donations are much larger, require
+  ongoing maintenance of their own, and/or introduce nuanced licensing issues
+
+Large donations – or small donations that turn up complex issues during PR
+review – should be referred to the Technical Committee (TC) by filing an issue
+in this `community` repository and tagging
+`@open-telemetry/technical-committee`. The TC will respond to donation
+proposals **within two weeks** (that is, after having time to meet and discuss
+live). If the TC has not responded to the donation request within that
+interval, the donating party can and should point to this document and request
+guidance at the TC's earliest convenience.
+
+All donated code requires a license compatible with the Apache Software License
+2.0 (ASL 2), and donated code will require a change of copyright to reflect the
+OpenTelemetry Authors.

 The TC recognizes that maintainers of specific languages or sub-projects have significant autonomy over their SIG and implementations.  The TC’s focus is on cross-project or disputed concerns with a primary goal of seeking consensus to develop an appropriate technical solution. The TC will define OpenTelemetry’s release vehicles and serve as the primary technical liaison body for the OpenTelemetry project with the CNCF's TOC, external open source projects, consortiums and groups.
