+   ⚠️ coverage-badge is in maintenance mode. I might still do occasional updates
+   and fixes from time to time, but there will be no added features. Most
+   people using coverage-badge might want to use genbadge_ instead, which has
+   more features (e.g. test badges, flake8 reports, etc).

 The badge template has been taken from shields.io_, therefore it should look
 mostly good. (The spec is a bit stricter on the margins, but I can't easily do
 text width calculations in Python so the margins might not always be 4px.)

-(e.g. test badges, flake8 reports, etc), check out genbadge_.
