+(This is a work in progress).
+
+## General rules
+
+- PEP8 as general fallback recommendations
+- Max line length: 120
+- Avoid overcomplex compound statements. i.e. dont do this: `somevar = x if x == y else z if a == b and c == b else x`
+
+## Indentation style
+
+### Multi-line functions
+
+```python
+foo(really_long_arg_1,
+    really_long_arg_2)
+```
+
+### Mutli-line lists/dicts
+
+```python
+foo = {
