@michaelfraga: not sure which readme file you mean, unless you are talking about the tips.txt file. that might help you a little.

Once you have selected your carrier, then just start selecting the OEM's (programs) you want to have on your phone. to find out more about what a particular program does/is- you can right click on the name of it in BuildOS, then read the OEM info about it or visit the website for the program if it is listed.
any selections with a circle style check box means you can only select one of those. any with the square style check box means you can select more than one if you like. once you are done selecting your programs, then you should save your selections file by clicking on File, then Save As menu. this way the original Selections.txt file will not get overwritten.

then you would click the green Build Rom button at the top and watch it go! you can have your phone already plugged in and synced so when the rom is completed and the RUU starts you can go ahead and flash your phone.
