Add compile instruction to compile profile-bee?

[vincentmli]

Hi,

Could you add instruction to compile profile-bee, sorry totally newbie to rust here :)

Hi @vincentmli all you need to do is mentioned here.
https://github.com/zz85/profile-bee#development

In case you are not familiar with cargo and friends you should read something about in the rust book. Let me drop a link.
