+# Development documentation for librsvg
+
+Two things here: design documents for developers of librsvg itself,
+and a roadmap for development.
+
+Before embarking on big changes, please write a little design document
+modeled on the following ones, and submit a merge request.  We can
+then discuss it before coding.  This way we will have a sort of
+big-picture development history apart from commit messages.
+
+Design documents:
+
+* [`adding-a-property.md`](adding-a-property.md) - Tutorial on how to
+  add support for a new CSS property.  Should remain always current.
+  
+* [`text-layout.md`](text-layout.md) - Status of the text layout
+  engine as of librsvg 2.52.3, and a roadmap for improvement.  Still
+  current as of 2021/Dec/17.
+
+# Roadmap - an ever-changing list of development priorities - check this often
+
+## Short term
+
+* Update the CI pipelines for the main and stable branches; a design document is upcoming.
+
+* #778 is not the common case, but worrysome.
+
+* Continue with the [revamp of the text engine](text-layout.md).
+
+## Medium term
+
+* Switch to meson, for real now.
+
+* Convert C API docs to gi-docgen.
+
+* After that, #552 - Build the C library with cargo-c.
