LFS documentation is perfect. you need to have internet connection to download packages and compile it from source code and install them.
Remember LFS takes lot of time , I have spent a day on it ,but didn't work. I messed something. Then few weeks back,It took almost 3 days to complete it.
You will learn a lot with LFS. Any issues ,you can always post them here
