Anyone know how to use audacity

like the title says,
recently ive downloaded audacity a program i once used to create some sound clips for an old charecter i might have done half a decade ago or maybe longer
i was just wondering if there was anyone really good at it to consult when i need to use it again and have it do something specific

5-10 years ago the Audacity versions (1.x.x) were old; now the latest version is 2.2.0.

I use Audacity mainly for sound recording and audio converting, but I seldom edit the sounds.  I don't know how much you need to use Audacity on your sounds/audio files after your 5-10 years ago, so I suggest that you might want to consult their 2.2.0 online documentation here :  http://manual.audacityteam.org/index.html#using
