the instructions to install the mymcplusplus gui are confusing

[Diegopie007]

if you use "pip install mymcplusplus[gui]" it wont actually start when typing "mymcplusplus" in the command prompt. only by using "pip install mymcplusplus" you'll be able to install the gui as well and the program will then be able to start.

When installing Python you need to check "PATH environment variable".
