* Add via support

remove via json file later

* added oled driver and i2c configuration

* update to correct driver block macros

* fix faulty configuration for i2c

* remove via support

* enable console by default

* rework layout slightly

* fix default keymap

* cleanup

* fix comment

* update readme

* add copyright headers to pass lint check

* apply clang-formatter

* refactor folder structure slightly

* quickfix name

* bump readme

* rework for data driven conf

* apply formatter json and update naming

* forgot one

* slight adjustment

* use smaller copyright

* minor change to name

+# Orbiter Wired
+
+A 52-key split keyboard.
+
+![Orbiter v1.00](https://i.imgur.com/7KSPaIT.jpeg)
+
+* Keyboard Maintainer: [Karl Stralman](https://github.com/kjeller)
+* Hardware Supported: Orbiter v1.00
+* Hardware Availability: [Github KiCad project](https://github.com/kjeller/orbiter_keyboard/tree/master/pcb/orbiter-wired)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make supercrisp/orbiter:default
+
+Flashing example for this keyboard:
+
+    make supercrisp/orbiter:default:flash
+
+See the [build environment setup](getting_started_build_tools) and the [make instructions](getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](newbs).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
