How exciting, you are in for a wild ride! Nothing as adorable as a basenji puppy. Take her out every couple of hours, stay with her , walk her, praise, praise & praise when she does her business (give it a name so she will figure out what you are praising). The timing is important, like instant praise!
Accidents..ignore, clean well with an odor/protein remover like Natures Miracle. As others have said, do a search for potty or house training and you will see lots of good information. Some train faster than others, don't get discouraged if your girl is not an "A+ student", she will get it eventually!
Our first puppy (we already had adults, rescues) was a smart girl but she would pee in the hallway at night. We have a dog door so they can go out at will, day or night. She was perfect during the day, but at night, the hall was as far as she got. Eventually, she made it all the way to the back door!
