+# Design guidelines
+Guidelines for UI design, covering GUI, CLI, documentation, log messages, etc
+
+## Text
+#### Sentences
+Short, single-sentence text do NOT end in a period.
+
+Multi-sentence text ALWAYS ends in a period.
+
+#### Casing
+We prefer normal casing, and avoid Title Casing.
+
+We only use Title Casing for company and product names (Rerun, Rerun Viewer, Discord, …), but NOT for concepts like “container”, “space view”, etc.
+
+#### Examples
+Good: `log("File saved")`
+
+Bad: `log("file saved.")`
+
+### Buttons
+
+When a button action requires more input after pressing, suffix it with `…`.
+
+Good: `Save recording…` (leads to a save-dialog)
+
+## GUI labels
+
+We do not use a colon suffix for labels in front of a value.
+
+Good: `Color 🔴`
+
+Bad: `Color: 🔴`
