+
+![Isometria sample image](https://mpwr.xyz/projects/isometria75/preview/elmo_pc_BOW_overview.png)
+
+A 75% ISO-only board with a rotary encoder, RGB underglow and single color dimmable backlight. The hardware is ready to have Bluetooth support added later on. The design is open source and all files (PCB and case) can be found in my [Github repo](https://github.com/ebastler/isometria-75).
+
+* Keyboard Maintainer: [ebastler](https://github.com/ebastler)
+* Hardware Supported: Rev1 PCB, see Github repo linked above
+* Hardware Availability: None, feel free to order/manufacture parts yourself.
+
+Bootmagic Lite key: Escape
+Physical reset switch present on the bottom of the PCB
+
+Make example for this keyboard (after setting up your build environment):
+
+    make ebastler/isometria_75/rev1: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).
+
+
+## Default keymap layout binds
+
+Layer 1 toggle: Right menu key (to the right of ralt, left of the arrow cluster)
+Layer 2 toggle: Right menu key + right shift key
+
+Alternate layer mod keys (All on layer 1):
+* Home: Insert
+* Backspace: Delete
+
+Alternate layer hardware control keys (All on layer 1):
+* Esc: Enable/disable underglow
+* F1/F2: lower/increase underglow brightness
+* F3/F4: lower/increase backlight brightness
+* F5/F6: lower/increase underglow hue
+* F7/F8: lower/increase underglow saturation
+* F9/F10: previous/next underglow effect
+* F11/F12: lower/increase underglow effect speed
+* Print Sreen: Shortcut to static underglow
+
+Encoder mapping (Layer 0):
+* CCW/CW: Decrease/Increase volume
+* Click: Play/Pause
+
+Encoder mapping (Layer 1):
+* CCW/CW: Previous/Next track
+* Click: Mute audio
+
+Encoder mapping (Layer 2):
+* CCW/CW: Screen brightness up/down
