+# Contribution Guidlines
+
+This library is the culmination of the expertise of many members of the open source community who have dedicated their time and hard work. The best way to ask for help or propose a new idea is to [create a new issue](https://github.com/z3t0/Arduino-IRremote/issues/new) while creating a Pull Request with your code changes allows you to share your own innovations with the rest of the community.
+
+The following are some guidelines to observe when creating issues or PRs:
+- Be friendly; it is important that we can all enjoy a safe space as we are all working on the same project and it is okay for people to have different ideas
+- [Use code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code); it helps us help you when we can read your code! On that note also refrain from pasting more than 30 lines of code in a post, instead [create a gist](https://gist.github.com/) if you need to share large snippets
+- Use reasonable titles; refrain from using overly long or capitalized titles as they are usually annoying and do little to encourage others to help :smile:
+- Be detailed; refrain from mentioning code problems without sharing your source code and always give information regarding your board and version of the library 
+
+If there is any need to contact me then you can find my email on the README, I do not mind responding to emails but it would be in your own interests to create issues if you need help with the library as responses would be from a larger community with greater knowledge!

 # IRremote Arduino Library
-This library enables you to send and receive using infra-red signals on an arduino
 
-## Version - 1.00
+[![Build Status](https://travis-ci.org/z3t0/Arduino-IRremote.svg?branch=master)](https://travis-ci.org/z3t0/Arduino-IRremote)
+
+[![Join the chat at https://gitter.im/z3t0/Arduino-IRremote](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/z3t0/Arduino-IRremote?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+This library enables you to send and receive using infra-red signals on an Arduino.
+
+Tutorials and more information will be made available on [the official homepage](http://z3t0.github.io/Arduino-IRremote/).
+
+## Version - 2.4.0b
 
 ## Installation
-1. Click "Download ZIP" 
-2. Extract the downloaded zip file 
-3. Rename the extracted folder from "Arduino-IRremote" to "IRremote"
-4. Move this folder to your libraries directory
+1. Navigate to the [Releases](https://github.com/z3t0/Arduino-IRremote/releases) page.
+2. Download the latest release.
+3. Extract the zip file
+4. Move the "IRremote" folder that has been extracted to your libraries directory.
+5. Make sure to delete Arduino_Root/libraries/RobotIRremote. Where Arduino_Root refers to the install directory of Arduino. The library RobotIRremote has similar definitions to IRremote and causes errors.
+
+
+## FAQ
+- IR does not work right when I use Neopixels (aka WS2811/WS2812/WS2812B)  
+Whether you use the Adafruit Neopixel lib, or FastLED, interrupts get disabled on many lower end CPUs like the basic arduinos. In turn, this stops the IR interrupt handler from running when it needs to. There are some solutions to this on some processors, [see this page from Marc MERLIN](http://marc.merlins.org/perso/arduino/post_2017-04-03_Arduino-328P-Uno-Teensy3_1-ESP8266-ESP32-IR-and-Neopixels.html)
+
+
+## Supported Boards
+- Arduino Uno / Mega / Leonardo / Duemilanove / Diecimila / LilyPad / Mini / Fio / Nano etc.
+- Teensy 1.0 / 1.0++ / 2.0 / 2++ / 3.0 / 3.1 / Teensy-LC; Credits: @PaulStoffregen (Teensy Team)
+- Sanguino
+- ATmega8, 48, 88, 168, 328
+- ATmega8535, 16, 32, 164, 324, 644, 1284,
+- ATmega64, 128
+- ATtiny 84 / 85
+- ESP32 (receive only)
+- ESP8266 is supported in a fork based on an old codebase that isn't as recent, but it works reasonably well given that perfectly timed sub millisecond interrupts are different on that chip. See https://github.com/markszabo/IRremoteESP8266
+
+We are open to suggestions for adding support to new boards, however we highly recommend you contact your supplier first and ask them to provide support from their side.

+Please only email me if it is more appropriate than creating an Issue / PR. I **will** not respond to requests for adding support for particular boards, unless of course you are the creator of the board and would like to cooperate on the project. I will also **ignore** any emails asking me to tell you how to implement your ideas. However, if you have a private inquiry that you would only apply to you and you would prefer it to be via email, by all means.

+// From what I have seen, the only time we go over 8-bits is the 'space'
+// on the end which creates the lead-out/inter-code gap.  Assuming I'm right,
+// we can code this up as a special case and otherwise halve the size of our
+// data!
+// Ignoring the first four values (the config data) and the last value
+// (the lead-out), if you find a protocol that uses values greater than 00fe
+// we are going to have to revisit this code!
+//
+//
+// So, the 0th byte will be the carrier frequency in Khz (NOT Hz)
+//      "  1st  "    "   "   "  length of the "once" code
+//      "  2nd  "    "   "   "  length of the "repeat" code
+//
+// Thereafter, odd  bytes will be Mark  lengths as a multiple of USECPERTICK uS
+//             even   "     "  "  Space    "    "  "    "     "       "      "
+//
+// Any occurence of "FF" in either a Mark or a Space will indicate
+//   "Use the 16-bit FF value" which will also be a multiple of USECPERTICK uS
+//
+//
+// As a point of comparison, the test code (prontoTest[]) is 520 bytes
+// (yes, more than 0.5KB of our Arduino's precious 32KB) ... after conversion
+// to pronto hex that goes down to ((520/5)*2) = 208 bytes ... once converted to
+// our format we are down to ((208/2) -1 -1 +2) = 104 bytes
+//
+// In fariness this is still very memory-hungry
+// ...As a rough guide:
+//   10 codes cost 1K of memory (this will vary depending on the protocol).
+//
+// So if you're building a complex remote control, you will probably need to
+// keep the codes on an external memory device (not in the Arduino sketch) and
+// load them as you need them.  Hmmm.
+//
+// This dictates that "Oscillated Pronto Codes" are probably NOT the way forward
+//
+// For example, prontoTest[] happens to be: A 48-bit IR code in Denon format
+// So we know it starts with 80/40                           (Denon header)
+//             and ends with 10/aa6                          (Denon leadout)
+//             and all (48) bits in between are either 10/10 (Denon 0)
+//                                                  or 10/30 (Denon 1)
+// So we could easily store this data in 1-byte  ("Denon")
+//                                     + 1-byte  (Length=48)
+//                                     + 6-bytes (IR code)
+// At 8-bytes per code, we can store 128 codes in 1KB or memory - that's a lot
+// better than the 2 (two) we started off with!
+//
+// And serendipitously, by reducing the amount of data, our program will run
+// a LOT faster!
+//
+// Again, I repeat, even after you have spent time converting the "Oscillated
+// Pronto Codes" in to IRremote format, it will be a LOT more memory-hungry
+// than using sendDenon() (or whichever) ...BUT these codes are easily
+// available on the internet, so we'll support them!

+Assuming the protocol we are adding is for the (imaginary) manufacturer:  Shuzu
+
+Our fantasy protocol is a standard protocol, so we can use this standard
+template without too much work. Some protocols are quite unique and will require
+considerably more work in this file! It is way beyond the scope of this text to
+explain how to reverse engineer "unusual" IR protocols. But, unless you own an
+oscilloscope, the starting point is probably to use the rawDump.ino sketch and
+try to spot the pattern!
+
+Before you start, make sure the IR library is working OK:
+  # Open up the Arduino IDE
+  # Load up the rawDump.ino example sketch
+  # Run it
+
+Now we can start to add our new protocol...
+
+1. Copy this file to : ir_Shuzu.cpp
+
+2. Replace all occurrences of "Shuzu" with the name of your protocol.
+
+3. Tweak the #defines to suit your protocol.
+
+4. If you're lucky, tweaking the #defines will make the default send() function
+   work.
+
+5. Again, if you're lucky, tweaking the #defines will have made the default
+   decode() function work.
+
+You have written the code to support your new protocol!
+
+Now you must do a few things to add it to the IRremote system:
+
+1. Open IRremote.h and make the following changes:
+   REMEMEBER to change occurences of "SHUZU" with the name of your protocol
+
+   A. At the top, in the section "Supported Protocols", add:
+      #define DECODE_SHUZU  1
+      #define SEND_SHUZU    1
+
+   B. In the section "enumerated list of all supported formats", add:
+      SHUZU,
+      to the end of the list (notice there is a comma after the protocol name)
+
+   C. Further down in "Main class for receiving IR", add:
+      //......................................................................
+      #if DECODE_SHUZU
+          bool  decodeShuzu (decode_results *results) ;
+      #endif
+
+   D. Further down in "Main class for sending IR", add:
+      //......................................................................
+      #if SEND_SHUZU
+          void  sendShuzu (unsigned long data,  int nbits) ;
+      #endif
+
+   E. Save your changes and close the file
+
+2. Now open irRecv.cpp and make the following change:
+
+   A. In the function IRrecv::decode(), add:
+      #ifdef DECODE_NEC
+          DBG_PRINTLN("Attempting Shuzu decode");
+          if (decodeShuzu(results))  return true ;
+      #endif
+
+   B. Save your changes and close the file
+
+You will probably want to add your new protocol to the example sketch
+
+3. Open MyDocuments\Arduino\libraries\IRremote\examples\IRrecvDumpV2.ino
+
+   A. In the encoding() function, add:
+      case SHUZU:    Serial.print("SHUZU");     break ;
+
+Now open the Arduino IDE, load up the rawDump.ino sketch, and run it.
+Hopefully it will compile and upload.
+If it doesn't, you've done something wrong. Check your work.
+If you can't get it to work - seek help from somewhere.
+
+If you get this far, I will assume you have successfully added your new protocol
+There is one last thing to do.
+
+1. Delete this giant instructional comment.
+
+2. Send a copy of your work to us so we can include it in the library and
+   others may benefit from your hard work and maybe even write a song about how
+   great you are for helping them! :)

+  BlueChip
