+## Configuration
+*pyfx* can be configured using YAML, the config file is either passed directly through CLI option or automatically
+loaded in predefined config folderq.
 
-### Key Mappings
+If *pyfx* is invoked without `-c / --config` option, it will search config file in with the following order:
+1. ~/.config/pyfx/config.yml
+2. PYTHON_DIR/site-packages/pyfx/config/config.yml
+
+### Predefined Key Mappings
+Key mapping is configured with the following configuration schema
+```
+keymap:
+  mode: string, accepted_options = ["basic" (The default) | "emacs" | "vim"]
+```
