Letting your readers know what you’ve been doing on Twitter is very important, especially when they can be turned into new followers and, why not, also future clients. This widget is easy to use and extremely helpful at the same time.
Because of the upgrade to Twitter API v1.1, this widget requires that you FIRST insert your personal Twitter account info. You do this from Admin – Appearance – Theme Options – Social & Contact. Read more here – http://help.wpresidence.net/2015/10/29/social-contact/
Take this info from https://apps.twitter.com/. Login and follow instructions.
Then you can go to Widgets and add it to the sidebar. You can specify the Twitter ID and the no of tweets you’d like to show.
