+## "Complex" Flag Branch
-- [Variant Flags](https://git.vwolfe.io/valerie/pride/src/branch/variant)
+
-- ["Complex" Flags](https://git.vwolfe.io/valerie/pride/src/branch/complex)
+This branch adds "complex" flags that require a little more effort to render than
+iterating over an array of colors. Currently, the branch aims to add the following
+flags:
+- Progress: 2018 rainbow pride flag with black and brown and transgender flag chevrons
+- Aro/Ace: side-by-side aromantic and asexual combination flag
+- Intersex: a yellow flag with a purple circle
+- Polyamorous: three-stripe flag with an isosceles triangle cut-in and a heart
