 ## Helper Script for building from source
 Go to the directory with PyBitmessage source code and run:
 ```
 python checkdeps.py
 ```
-If there are missing dependencies, it will explain you what is missing and for many Unix-like systems also what you have to do to resolve it. You need to repeat calling the script until you get nothing mandatory missing. How you then run setuptools depends on whether you want to install it to user's directory or system.
