-The LLVM Project relies on two features of its process to maintain rapid
-development in addition to the high quality of its source base: the combination
-of code review plus post-commit review for trusted maintainers.  Having both is
-a great way for the project to take advantage of the fact that most people do
-the right thing most of the time, and only commit patches without pre-commit
-review when they are confident they are right.
-
-The trick to this is that the project has to guarantee that all patches that are
-committed are reviewed after they go in: you don't want everyone to assume
-someone else will review it, allowing the patch to go unreviewed.  To solve this
-problem, we have a notion of an 'owner' for a piece of the code.  The sole
-responsibility of a code owner is to ensure that a commit to their area of the
-code is appropriately reviewed, either by themself or by someone else.  The list
-of current code owners can be found in the file `CODE_OWNERS.TXT
-<https://github.com/llvm/llvm-project/blob/main/llvm/CODE_OWNERS.TXT>`_ in the
-root of the LLVM source tree.
-
-Note that code ownership is completely different than reviewers: anyone can
-review a piece of code, and we welcome code review from anyone who is
-interested.  Code owners are the "last line of defense" to guarantee that all
-patches that are committed are actually reviewed.
-
-Being a code owner is a somewhat unglamorous position, but it is incredibly
-important for the ongoing success of the project.  Because people get busy,
-interests change, and unexpected things happen, code ownership is purely opt-in,
-and anyone can choose to resign their "title" at any time. For now, we do not
-have an official policy on how one gets elected to be a code owner.
+The LLVM Project aims to evolve features quickly while continually being in a
+release-ready state. In order to accomplish this, the project needs volunteers

Super nit.
