+# Feker IK75
+
+A 75% exploded keyboard made by Feker, which controlled by an Atmega32u4 chipset. The keyboard features per-key RGB, RGB underglow and 1 encoder.
+
+* Keyboard Maintainer: Feker
+* Hardware Supported: Atmega32u4
+* Hardware Availability: https://epomaker.com/products/epomaker-feker-ik75-v3-qmk-via
+
+Make example for this keyboard (after setting up your build environment):
+
+    make feker/ik75:default
+
+Flashing example for this keyboard:
+
+    make feker/ik75:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (Esc key) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB
+* **Keycode in layout**: Press the key mapped to RESET if it is available
