+ * @file custom_shift_keys.h
+ * @brief Custom shift keys: customize what keycode is produced when shifted.
+ *
+ * Overview
+ * --------
+ *
+ * This library implements custom shift keys, keys where you can customize
+ * what keycode is produced when shifted.
+ *
+ * Step 1: In your keymap.c, define a table of custom shift keys like
+ *
+ *     #include "features/custom_shift_keys.h"
+ *
+ *     const custom_shift_key_t custom_shift_keys[] = {
+ *       {KC_DOT , KC_QUES}, // Shift . is ?
+ *       {KC_COMM, KC_EXLM}, // Shift , is !
+ *       {KC_MINS, KC_EQL }, // Shift - is =
+ *       {KC_COLN, KC_SCLN}, // Shift : is ;
+ *     };
+ *
+ * Each row defines one key. The first field is the keycode as it appears in
+ * your layout and determines what is typed normally. The second entry is what
+ * you want the key to type when shifted.
+ *
+ * Step 2: Handle custom shift keys from your `process_record_user` function as
+ *
+ *     bool process_record_user(uint16_t keycode, keyrecord_t* record) {
+ *       if (!process_custom_shift_keys(keycode, record)) { return false; }
+ *       // Your macros ...
+ *
+ *       return true;
+ *     }
+ *
+ * Step 3: add `features/custom_shift_keys.c` to your rules.mk as
+ *
+ *     SRC += features/custom_shift_keys.c
+ *
+ *
+ * For full documentation, see
+ * <https://getreuer.info/posts/keyboards/custom-shift-keys>
