+Thank you for opening an issue on an Adafruit Python 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 Python/Raspberry Pi projects check these very common issues to ensure they don't apply**:
+
+  - If you are receiving an **ImportError: No module named...** error then a
+    library the code depends on is not installed.  Check the tutorial/guide or
+    README to ensure you have installed the necessary libraries.  Usually the
+    missing library can be installed with the `pip` tool, but check the tutorial/guide
+    for the exact command.  
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and power 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.
+
+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:
+
+- Platform/operating system (i.e. Raspberry Pi with Raspbian operating system,
+  Windows 32-bit, Windows 64-bit, Mac OSX 64-bit, etc.):  **INSERT PLATFORM/OPERATING
+  SYSTEM HERE**
+
+- Python version (run `python -version` or `python3 -version`):  **INSERT PYTHON
+  VERSION HERE**
+
+- Error message you are receiving, including any Python exception traces:  **INSERT
+  ERROR MESAGE/EXCEPTION TRACES HERE***
+
+- List the steps to reproduce the problem below (if possible attach code or commands
+  to run): **LIST REPRO STEPS BELOW**

+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.

+Adafruit_Python_CharLCD
+=======================
+
+Python library for accessing Adafruit character LCDs from a Raspberry Pi or BeagleBone Black.
+
+Designed specifically to work with the Adafruit character LCDs ----> https://learn.adafruit.com/character-lcds/overview
+
+For all platforms (Raspberry Pi and Beaglebone Black) make sure you have the following dependencies:
+
+````
+sudo apt-get update
+sudo apt-get install build-essential python-dev python-smbus python-pip
+````
+
+For a Raspberry Pi make sure you have the RPi.GPIO library by executing:
+
+````
+sudo pip install RPi.GPIO
+````
+
+For a BeagleBone Black make sure you have the Adafruit_BBIO library by executing:
+
+````
+sudo pip install Adafruit_BBIO
+````
+
+Install the library by downloading with the download link on the right, unzipping the archive, navigating inside the library's directory and executing:
+
+````
+sudo python setup.py install
+````
+
+See example of usage in the examples folder.
+
+Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
