+Anselme short tutorial
+======================
+
+This document is a work-in-progress and currently mostly useless.
+
+Level 1: basics
+---------------
+
+Basics of Anselme. Should be enough to make a "choose-your-own-adventure" type script using the test game runner.
+
+### Text
+
+Writing simple text.
+
+### Choices
+
+Defining multiple choices.
+
+### Basic functions
+
+Defining functions without arguments and switching to them.
+
+### Variables and conditions
+
+Variable & constant definition, simple conditions and expressions.
+
+Level 2: intermediate
+---------------------
+
+More advanced features that you would likely need if you intend to integrate Anselme into your game.
+
+### Checkpoints
+
+Purpose and how they work.
+
+### Tags
+
+Tag lines, subtexts.
+
+### Events and adding Anselme to your game
+
+Events buffer, basic Lua API.
+
+### Other line types
+
+Loops, comments.
+
+Level 3: advanced
+-----------------
+
+If you want to make full use of Anselme's features for your game, or just want to flex about a language nobody's heard of in your CV. This part will assume previous programming knowledge.
+
+### Advanced functions
+
+Arguments, scopes, return values.
+
+### Advanced expressions
+
+Variable types, operators, built-in functions. This part is going to be long...
+
+#### General rules of an expression
+
+#### Operators
+
+#### Main types
+
+#### Sequences and maps
+
+#### Objects
+
+#### References
+
+#### Function dispatch
+
+### Translation
+
+Aliases, what can be translated, what is saved.
