+Based on what we've learned from our [Moti project](http://github.com/weareleka/moti), this repo will allow you to:
 
 - move away from the Arduino IDE and use your favorite text editor such as Vim or SublimeText
 - get up and running in less time
-- use `avr-gcc 8.3.0` to compile your code
+- use the latest version of `avr-gcc 9.x.x` to compile your code
 - use `C++17` for your standard coding
 - use `make` to compile, `make upload` to upload, thanks to [Sudar](https://github.com/sudar/)'s incredible project [Arduino-Makefile](https://github.com/sudar/Arduino-Makefile)
-- use our [Travis-CI](https://travis-ci.org) continuous integration configuration and adapt it to suit your needs

 To code in C/C++, we highly recommend using [SublimeClang](https://github.com/boxdot/SublimeClang), ~~even if the plugin is not maintained anymore~~ (this fork seems to be up-to-date). ~~As far as we can tell, it works beautifully well and will save you a lot of time!~~ :)

 > YouCompleteMe is a fast, as-you-type, fuzzy-search code completion engine for Vim. It has several completion engines: an identifier-based engine that works with every programming language, a semantic, Clang-based engine that provides native semantic code completion for C/C++/Objective-C/Objective-C++ (from now on referred to as "the C-family languages"), a Jedi-based completion engine for Python, an OmniSharp-based completion engine for C\# and an omnifunc-based completer that uses data from Vim's omnicomplete system to provide semantic completions for many other languages (Ruby, PHP etc.).
