+Dashboard: `<https://membrowse.com/public/apache/nuttx>`_
+
+The memory footprint of a set of representative targets is tracked over time
+using `MemBrowse <https://membrowse.com>`_. This makes flash/RAM usage changes
+visible on a per-section and per-symbol basis and helps catch unintended size
+regressions. It:
+
+* provides a trend graph of the builds across commits
+* lets you compare the footprint between any two uploaded commits
+* posts a footprint summary comment on each pull request

+The integration consists of:
