+
+## Calls for Testing
+
+An important step for RFC implementation is for people to experiment with the
+implementation and give feedback, especially before stabilization.  The following
+RFCs would benefit from user testing before moving forward:
+
+<!-- Calls for Testing go here, use this format:
+    * [<RFC Topic>](<RFC URL>)
+        * [Tracking Issue](<Tracking Issue URL>)
+        * [Testing steps](<Testing Steps URL>)
+-->
+<!-- or if there are no new or updated RFCs this week, use: -->
+<!-- * *No New or Updated RFCs were created this week.* -->
+<!-- Remember to remove the `call-for-testing` label from the RFC so that the maintainer can signal for testers again, if desired. -->
+
+### [RFCs](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
+
+### [Rust](https://github.com/rust-lang/rust/labels/call-for-testing)
+
+### [Rustup](https://github.com/rust-lang/rustup/labels/call-for-testing)
+
+If you are a feature implementer and would like your RFC to appear on the above list, add the new `call-for-testing`
+label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature
+need testing.
+
