+- [refactor] [#267](https://github.com/vcs-python/libvcs/pull/267) overhaul docs
+
+  - Move docstring format to Numpy-style
+
+  - Move from reStructuredText to Markdown (via recommonmark). The master plan is to eliminate
+    docutils and sphinx as a bottleneck completely in favor of something else (e.g. gatsby with
+    a source that inspects our modules and can source intersphinx)
+
+  - Move from RTD to GitHub Action, full support of poetry extras packages, deploys straight to
+    S3 and CloudFront
