 ## Calls for Testing
+
 An important step for RFC implementation is for people to experiment with the
 implementation and give feedback, especially before stabilization.
 
 If you are a feature implementer and would like your RFC to appear in this list, add a
 `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.
 
-<!-- If there are new CfT items this week, include:
-
-  [Repo Name](Repo URL)
-    * [<Feature name>](<Feature URL>)
-        * [Testing steps](<Testing Steps URL>)
-
-  - and make note in the item so the authors know to remove the `call-for-testing` label:
-This RFC will appear in the **Call for Testing** section of the next issue (#) of This Week in Rust (TWiR).
-You may remove the `call-for-testing` label.  Please feel free to leave the `call-for-testing` label in place if you would like this RFC to appear again in another issue of TWiR.

-[Cargo](https://github.com/rust-lang/cargo/labels/call-for-testing) or
-[Rustup](https://github.com/rust-lang/rustup/labels/call-for-testing)
-
-  - and `Testing steps` points directly to the procedures the item wants users to exercise.
-
-  - For all `Repo Names` with no new CfT items this week: use (removing the repos for which new
-     CfT items did appear, of course)
