+# Libraries
+
+Since some functionality is too specific to be included in the main Hakyll
+library, people have generously written utility libraries and tools for Hakyll.
+Here is a list of the ones I know of (I would be happy to hear about others).
+
+- [hakyll-contrib-links](http://hackage.haskell.org/package/hakyll-contrib-links),
+  a Hakyll library that helps maintain a separate links database.
+- [hakyll-agda](https://hackage.haskell.org/package/hakyll-agda),
+  a simple module useful to generate blog posts from literate Agda files.
+- [hakyll-contrib-hyphenation](http://hackage.haskell.org/package/hakyll-contrib-hyphenation),
+  automatic hyphenation for Hakyll.
+- [hakyll-convert](https://hackage.haskell.org/package/hakyll-convert),
+  a conversion tool from other blog engines to Hakyll.
+- [hakyll-elm](https://hackage.haskell.org/package/hakyll-elm),
+  Hakyll wrapper for the Elm compiler.
