Go to the Linux from Scratch website and tell them it should be called Linux from Source.
On the serious side, what do you want to achieve?
If you haven't installed Tiny Core and used it, I suggest you do that first. Information can be found on the wiki.
It can be installed much quicker than Mint.
If you want to make modifications, tiny core comes as a lot of separate parts, you can just modify the parts you want to modify, and use the others as they are.
If you want to add programs which are not already available, you can learn how to make extensions.
If you have specific questions, post them.
