+# 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.
 
-Check [here](http://shirriff.github.io/Arduino-IRremote/) for tutorials and more information.
+# todo
 
-## Version - 1.00
+- [ ] only keep base functions in the library
+- [ ] move all protocols to examples as sketches
+- [ ] notation for ir protocols
+- [ ] update keywords.txt
+- [ ] write some documentation on library development
+- [ ] write documentation for library usage
+- [ ] remove documentation from source code? cleaner code
+- [ ] write tutorials
+- [ ] update links (library.properties)
+- [ ] update travis coverage
+- [ ] create a rules list for issues and prs
+- [ ] create guidlines for contributions, line-endings, indentations etc.

+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 - 3.0.0b
 
 ## Installation
-1. Navigate to the [Releases](https://github.com/shirriff/Arduino-IRremote/releases) page.
+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.
+
+## 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
+
+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.
