+# Stenography in QMK
+
+[Stenography](https://en.wikipedia.org/wiki/Stenotype) is a method of writing most often used by court reports, closed-captioning, and real-time transcription for the deaf. In stenography words are chorded syllable by syllable with a mixture of spelling, phonetic, and shortcut (briefs) strokes. Professional stenographers can reach 200-300 WPM without any of the strain usually found in standard typing and with far fewer errors (>99.9% accuracy).
+
+The [Open Steno Project](http://www.openstenoproject.org/) has built an open-source program called Plover that provides real-time translation of steno strokes into words and commands. It has an established dictionary and supports
+
+## Plover with QWERTY Keyboard
+
+Plover can work with any standard QWERTY keyboard, although it is more efficient if the keyboard supports NKRO (n-key rollover) to allow Plover to see all the pressed keys at once. An example keymap for Plover can be found in `planck/keymaps/default`. Switching to the `PLOVER` layer adjusts the position of the keyboard to support the number bar.
+
+To use Plover with QMK just enable NKRO and optionally adjust your layout if you have anything other than a standard layout. You may also want to purchase some steno-friendly keycaps to make it easier to hit multiple keys.
+
+## Plover with Steno Protocol
+
+Plover also understands the language of several steno machines. QMK can speak a couple of these languages, TX Bolt and GeminiRP. An example layout can be found in `planck/keymaps/steno`.
+
+When QMK speaks to Plover over a steno protocol Plover will not use the keyboard as input. This means that you can switch back and forth between a standard keyboard and your steno keyboard, or even switch layers from Plover to standard and back without needing to activate/deactive Plover.
+
+In this mode Plover expects to speak with a steno machine over a serial port so QMK will present itself to the operating system as a virtual serial port in addition to a keyboard. By default QMK will speak the TX Bolt protocol but can be switched to GeminiRP; the last protocol used is stored in non-volatile memory so QMK will use the same protocol on restart.
+
+> Note: Due to hardware limitations you may not be able to run both a virtual serial port and mouse emulation at the same time.
+
+### TX Bolt
+
+TX Bolt communicates the status of 24 keys over a very simple protocol in variable-sized (1-5 byte) packets.
+
+### GeminiRP
+
+GeminiRP encodes 42 keys into a 6-byte packet. While TX Bolt contains everything that is necessary for standard stenography, GeminiRP opens up many more options, including supporting non-English theories.
+
+## Configuring QMK for Steno
+
+Firstly, enable steno in your keymap's Makefile. You should also diable mousekeys to prevent conflicts.
+
+```Makefile
+STENO_ENABLE = yes
+MOUSEKEY_ENABLE = no
+```
+
+In your keymap create a new layer for Plover. You will need to include `keymap_steno.h`. See `planck/keymaps/steno/keymap.c` for an example. Remember to create a key to switch to the layer as well as a key for exiting the layer. If you would like to switch modes on the fly you can use the keycodes `QK_STENO_BOLT` and `QK_STENO_GEMINI`. If you only want to use one of the protocols you may set it up in your initialization function:
+
+```C
+void matrix_init_user() {
+  steno_set_mode(STENO_MODE_GEMINI); // or STENO_MODE_BOLT
+}
+```
+
+Once you have your keyboard flashed launch Plover. Click the 'Configure...' button. In the 'Machine' tab select the Stenotype Machine that corresponds to your desired protocol. Click the 'Configure...' button on this tab and enter the serial port or click 'Scan'. Baud rate is fine at 9600 (although you should be able to set as high as 115200 with no issues). Use the default settings for everything else (Data Bits: 8, Stop Bits: 1, Parity: N, no flow control).
+
+On the display tab click 'Open stroke display'. With Plover disabled you should be able to hit keys on your keyboard and see them show up in the stroke display window. Use this to make sure you have set up your keymap correctly. You are now ready to steno!

+## Keycode Reference
+
+As defined in `keymap_steno.h`.
+
+> Note: TX Bolt does not support the full set of keys. The TX Bolt implementation in QMK will map the GeminiRP keys to the nearest TX Bolt key so that one key map will work for both.

+DeltaSplit75
+======
+
+This readme and most of the code are from https://github.com/ahtn/tmk_keyboard/ and https://github.com/qmk/qmk_firmware/tree/master/keyboards/lets_split
+
+Credit to ahtn and wootpatoot for work on the split keyboard firmware
+
+Split keyboard firmware for Arduino Pro Micro or other ATmega32u4
+based boards.
+
+## Case Files
+Files are available here: https://github.com/xyxjj/DeltaSplit75-Case-files
+
+## Build Guide
+The build guide should be found at https://qmk.fm/deltasplit75
+
+
+## First Time Setup
+
+Download or clone the whole firmware and navigate to the keyboards/deltasplit75 directory. Once your dev env is setup, you'll be able to generate the .hex using:
+
+```
+make v2
+
+or
+
+make v2-YOUR_KEYMAP_NAME (if you make a folder for your keymap)
+
+or
+
+make protosplit (if you have one of the prototype PCBs)
+```
+
+You will see a lot of output and if everything worked correctly you will see the built hex files:
+
+```
+deltasplit75_v2_protosplit.hex 
+
+or
+
+deltasplit74_v2_YOUR_KEYMAP_NAME.hex
+
+or
+
+deltasplit75_v2_default.hex
+
+```
+
+
+For more information on customizing keymaps, take a look at the primary documentation for [Customizing Your Keymap](/readme.md##customizing-your-keymap) in the main readme.md.
+
+### DeltaSplit75 V2
+The PCBs available in groupbuy are all v2, if you've bought one of my prototype PCBs (it says DeltaSplit65 on the silkscreen instead of 75), use the code make protosplit instead
+
+Features
+--------
+
+For the full Quantum Mechanical Keyboard feature list, see [the parent readme.md](/readme.md).
+
+Some features supported by the firmware:
+
+* Either half can connect to the computer via USB, or both halves can be used
+  independently.
+* 75% formfactor
+* Support for multiple Bottom Rows
+* RGB underglow support
+* Split Backspace and ISO support
+
+
+Flashing
+-------
+I personally use xLoader to upload my hex files to the keyboard, though any other working software is fine too
+
+
+Choosing which board to plug the USB cable into (choosing Master)
+--------
+Because the two boards are identical, the firmware has logic to differentiate the left and right board.
+
+It uses two strategies to figure things out: look at the EEPROM (memory on the chip) or looks if the current board has the usb cable.
+
+The EEPROM approach requires additional setup (flashing the eeeprom) but allows you to swap the usb cable to either side.
+
+The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
+
+### Setting the left hand as master
+If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` or `MASTER_RIGHT` if for some reason it was set.
+
+### Setting the right hand as master
+If you always plug the usb cable into the right board, add an extra flag to your `config.h`
+```
+ #define MASTER_RIGHT
+```
+
+### Setting EE_hands to use either hands as master
+If you define `EE_HANDS` in your `config.h`, you will need to set the
+EEPROM for the left and right halves.
+
+The EEPROM is used to store whether the
+half is left handed or right handed. This makes it so that the same firmware
+file will run on both hands instead of having to flash left and right handed
+versions of the firmware to each half. To flash the EEPROM file for the left
+half run:
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-lefthand.eep
+// or the equivalent in dfu-programmer
+
+```
+and similarly for right half
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep
+// or the equivalent in dfu-programmer
+```
+
+NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`)
+
+After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
+
+Note that you need to program both halves, but you have the option of using
+different keymaps for each half. You could program the left half with a QWERTY
+layout and the right half with a Colemak layout using bootmagic's default layout option.
+Then if you connect the left half to a computer by USB the keyboard will use QWERTY and Colemak when the
+right half is connected.
+
+
+Notes on Using Pro Micro 3.3V
+-----------------------------
+
+Do update the `F_CPU` parameter in `rules.mk` to `8000000` which reflects
+the frequency on the 3.3V board.
+
+Also, if the slave board is producing weird characters in certain columns,
+update the following line in `matrix.c` to the following:
+
+```
+// _delay_us(30);  // without this wait read unstable value.
+_delay_us(300);  // without this wait read unstable value.
+```

+# French hacker layout
+
+## Introduction
+
+[Colemak Mod-DH](https://colemakmods.github.io/mod-dh/) layout for
+users keeping an `azerty` layout configuration on their OS.
+
+This keymap is for users keeping their operating systems configured with
+`azerty` - for typing passwords or in their native languages - but who
+wants a Colemak Mod-DH layout on their mechanical.
+
+The symbols layers was done after analysing various programming
+languages sources codes and should be close to optimal for typing
+confort.
+
+Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
+
+There is an accented characters layer for infrequent typing of french
+accents.
+
+Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
+
+## Build
+
+    cd keyboards/ergodox
+    make french_hacker
+
+## Design explanations
+
+See my [blog post](http://dialectical-computing.de/blog/blog/2017/01/29/a-better-coder-layout-for-the-ergodox-ez-keyboard/).

+xd75 keyboard firmware
+======================
+
+The XD75Re is a 15x5 full-grid ortholinear keyboard manufactured by XIUDI. This port of the QMK firmware is my first shot at using QMK, so if you see any features done wrong (or just plain missing), feel free to fix them and put in a pull request!

+For more info on this firmware (and how to make it your own), head over to [qmk.fm](http://qmk.fm).
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboards/xd75 folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file. 
+
+Depending on which keymap you would like to use, you will have to compile slightly differently.
+
+### Default
+
+To build with the default keymap, simply run `make default`.
+
+### Other Keymaps
+
+The "default" keymap included is basically the OLKB Atomic keymap with a few buttons added for RGB underglow control. This should be usable as a starting point, but most people will be best served creating their own keymap and flashing it - more info on creating your own keymap is available in [the official QMK documentation](https://docs.qmk.fm).
+
+To build the firmware binary hex file with a keymap just do `make` with a keymap like this:
+
+```
+$ make [default|jack|<name>]
+```
+
+Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
