The task is simple, I just need someone to teach me how to compile Electrum standalone executable for windows from source code, and I pay in btc for this job. That's it.
Just take a look at above:
You can find step-by-step guides on github:
That should be enough. That's basically just typing the same commands.
And i am sure there are even more guides available online.
Just try following the guide. If you succeed you can donate that money to the development of electrum.
If you fail while doing a specific task, feel free to ask for further assistance.
