+The TSC seeks to resolve as many issues as possible outside meetings using
 [the TSC issue tracker](https://github.com/nodejs/TSC/issues). The process in
 the issue tracker is:
 
 * A TSC member opens an issue explaining the proposal/issue and @-mentions
   @nodejs/tsc.
-* After 72 hours, if there are two or more `LGTM`s from other TSC members and no
-  explicit opposition from other TSC members, then the proposal is approved.
-* If there are any TSC members objecting, then a conversation ensues until
-  either the proposal is dropped or the objecting members are persuaded. If
-  there is an extended impasse, a motion for a vote may be made.
+* The proposal passes if, after 72 hours, there are two or more TSC approvals
+  and no TSC opposition.
