-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

.github/PULL_REQUEST_TEMPLATE.md

@@ -1,26 +0,0 @@
-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.
-
-After reviewing the guidelines above you can delete this text from the pull request.

- *
- * This is the documentation for Adafruit's EPD driver for the
- * Arduino platform.  It is designed specifically to work with the
- * Adafruit EPD breakouts.
- *
- * These displays use SPI to communicate, 6 pins are required to
- * interface
- *
- * Adafruit invests time and resources providing this open source code,
- * please support Adafruit and open-source hardware by purchasing
- * products from Adafruit!
- *
- * @section dependencies Dependencies
- *
- * This library depends on <a

- * being present on your system. Please make sure you have installed the latest
- * version before using this library.
