Krunner plugins - basic questions from the new plasma dev

[Slawek Kaplonski]

Hi,

I'm user of the KDE since some time and now I want to get more familiar with 
its codebase and development process.
I wanted to write some simple Krunner plugin. I started doing that with the 
[1] guide but it seems like a bit old and outdated in some places. Is there 
anything newer and more up to date maybe?
And also second question is about building and running such new plugin. I 
started doing it in Kdevelop. I found that there is krunner plugin template 
already there so I started with it. But how I should run this plugin from the 
IDE? Is it possible on the running (production) system or should I run it 
somehow in some "sandbox"? Is there any guide for that maybe? Thx in advance 
for any help.
