+## Core Pillars
+
+Four core pillars: Mnemonic, Discoverable, Consistent and “Crowd-Configured”.
+
+If any of these core pillars is violated open an issue and we’ll try our best to fix it.
+
+### Mnemonic
+
+Key bindings are organized using mnemonic prefixes like b for buffer, p for project, s for search, h for help, etc…
+
+### Discoverable
+
+Innovative real-time display of available key bindings. Simple query system to quickly find available layers, packages, and more.
+
+### Consistent
+
+Similar functionalities have the same key binding everywhere thanks to a clearly defined set of conventions. Documentation is mandatory for any layer that ships with Spacemacs.
+
+### Crowd-Configured
+
+Community-driven configuration provides curated packages tuned by power users and bugs are fixed quickly.
