Making a Flash video for CD distrbution

I am new to this company and my employer who knows I haven’t worked with Flash asked me to look into making a flash video for new software that he developed. I have looked at the Adobe website but am not sure where to start. Can anybody point me to the right direction? Can I just download a editor, which one? Do I need something with the editor to make it work
:worried: Since I am new to the company I feel like he is testing me so I want to take this opportunity to shine. Thanks in advance for your help.
