diaspora* Environment setup

[chathurika senani]

I have Folked and cloned https://github.com/diaspora/diaspora, this repository to my local computer. And I want to start contributing to this project and searched for a document to setup the environment. Can anyone help e on this.
I have installed Ruby on my machine.

ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

Where can I start diaspora development and how to start?

https://wiki.diasporafoundation.org/Installation/Ubuntu/Trusty I found this and started following this article. While proceeding I met with this problem. Could not proceed installing bundle

ruby -v

ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]

cd diaspora/
bundle install

/usr/local/lib/site_ruby/1.9.1/rubygems.rb:270:in `find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)
    from /usr/local/lib/site_ruby/1.9.1/rubygems.rb:298:in `activate_bin_path'
    from /usr/bin/bundle:22:in `<main>'

sudo bundle install

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
