+Coding Style & Guidelines
+=========================
+
+The following sections contain |C_PICKER| coding guidelines. They are continually evolving and should not be considered "set
+in stone". Feel free to question them and provide feedback.
+
+The |C_PICKER| project uses multiple "domains" (textual content types, like programming languages) and each defines its own
+rules.
+
+To help configuring text editors the project comes with "`EditorConfig`_" file(s). (:download:`../../.editorconfig`).
+
+Shared rules
+------------
+
+The following rules are common for all domains, except where noted otherwise:
+
+#. Files shall be **UTF-8** encoded.
+#. Use **Unix** style line endings (``LF`` character)
+#. The primary language of the project is English. All comments and documentation must be in this language.
+#. Trailing whitespace is not welcome, please trim these.
+
+Python Domain
+-------------
+
+Python source code rules follow `PEP 8 -- Style Guide for Python Code`_.
+
+
+Restructured Text Domain
+------------------------
+
+Please refer to :ref:`Writing documentation`.
