-  I am proud of this one because it represents my ability to collaborate, to grasp
-  technically challenging concepts, and to get stuff done. After I joined I realized
-  that this was one of those situations where the team knew they desperately needed
-  a doc but could never prioritize the time and energy needed to create it. I knew
-  it was desperately needed because I had heard that many customers were confused by
-  these concepts and had explicitly requested docs on the topics. I got
-  the team lead and a few engineers together to brainstorm how to explain these ideas.
-  I am very thankful that I remembered to record the conversation, because I needed to
-  refer back to that meeting many times while drafting the doc. After [a couple rounds
-  of reviews](https://pigweed-review.googlesource.com/c/pigweed/pigweed/+/170602) the
-  doc published and now we have a solid explanation on the site for some absolutely
-  critical concepts!

+* [Facades and backends]. I am proud of this because it required deep collaboration
+  and ability to understand and explain complex concepts. As I was ramping up on
+  Pigweed I kept hearing how customers were confused about facades and backends. The
+  team knew we needed a doc on these concepts but just couldn't find the time to
+  prioritize the work. I got the team lead and a few engineers together to explain
+  these ideas and brainstorm how to document them. I'm thankful I recorded the
+  conversation because I referred back to that recording many times while drafting
+  the doc. Given that the engineers didn't request drastic rewrites during my [review]
+  I infer that I grokked the concepts pretty well. A key part of my grokking process is
+  to build prototypes myself: in this case I built a small embedded app that made use
+  of facades and backends.

+  I created these guidelines for web.dev contributors back when I was content lead
+  for that site.
