   This layer adds support for conlanging.
 
 ** Features
-   - Conversion from translittion to other alphabets
+   - Generate graphviz trees based on Elisp trees
-   - Open linguistic files
+   - Replace  some  text  by  its  runic equivalent  (supports  the  Mattér  and
+     Eittlandic languages)
+   - Adds phonetics to Ňyqy text
+   - Provides custom shortcuts
+
+** Graphviz trees
+   The ~conlanging~   layer    provides    one    public   function    called
+ ~conlanging/tree-to-dot~. It accepts as its sole argument a list of strings
+   or lists, such as the following:
+
+   #+NAME: vowels-example
+   #+BEGIN_SRC emacs-lisp :noweb yes
+     (setq-local vowels
+       '("[vowel]"
+         ("[back]"
+          ("[tense]"
+           ("[high]" ("ü"))
+           ("{high}" ("ö")))
+          ("{tense}"
+           ("[high]" ("u"))
+           ("{high}" ("o"))))
+         ("{back}"
+          ("[tense]"
+           ("[high]" ("y"))
+           ("{high}" ("ë")))
+          ("{tense}"
+           ("[high]" ("i"))
+           ("{high}" ("e"))))))
+   #+END_SRC
+
+   When passed in the above mentioned  function, and the result itself is passed
+   through graphviz, we get the following result:
+
+   #+NAME: tree-vowels
+   #+BEGIN_SRC emacs-lisp :exports results :noweb yes :cache yes
+     <<vowels-example>>
+     (conlanging/tree-to-dot vowels)
+   #+END_SRC
+
+   #+BEGIN_SRC dot :file img/vowels-example.png :var input=tree-vowels :exports results :cache yes
+     $input
+   #+END_SRC
+   #+NAME: arbre:vow
+   #+ATTR_HTML: :alt Exemple d’arbre de voyelles
+   #+RESULTS[cf778002d3abdd67ef0eba31e468ebdfe4e37400]:
+   [[file:img/vowels-example.png]]
+
+   This example tree is only a binary tree, but a single node can have up to ten
+   children.
