No. How about this: you go through the link, think about what it says, think about what you want to know, formulate a question, and then ask that question. Include a schematic.
Most "instructables" aren't very instructive. Why don't you simply state what you want to accomplish, and someone here will likely be able to help. For example, here is a project that I completed using the LM386. The design is largely taken from the LM386 datasheet (which you should download and read.)
The LM386 will not make a great guitar amp, but it will make a decent practice amp if you add a preamp stage to the front end. Read this thread and you will find the details of one that I built, which worked fairly well for practice.
