Help with running application Nano 3G

[Laniakea78878]

Hello. I really dont have knowledge on running commands and how to even get "communication" with the device. i heard you need to use linux, but even then I dont know how to run the command in the "read me" text file. If someone can tell me what programs to use, or even beter, if i need linux to tell me what linux opperating system i need (perferably free). Any help would be greatly appreciated.
