Instructions for compilation are a little confusing: docs need to be updated

Hi in the downloads page instructions are given for getting started with metamath. In particular after unzipping the .tar.gz one cannot immediately run gcc *.c -o metamath and expect it to work. They need to update the command to gcc src/*.c -o metamath or cd into src before executing the command.

On May 07, 2024 I downloaded the file [metamath.tar.gz](https://us.metamath.org/downloads/metamath.tar.gz) onto my Mac running Mac OS Big Sur.

After downloading this file I unzipped it with tar xvzf this command ran successfully and created a metamath directory.

I was able to cd into this directory and here are its contents

At this stage of the instructions something goes awry

The instructions clearly state to run gcc *.c -o metamath however as my screenshot above shows, there are no .c files to be found in the root and so when I run it it fails as expected.

I believe that this command needs to be run from the src directory which appears to have all the .c and .h files needed.

This command appears to work fine. And furthermore executing ./metamath set.mm afterwards seems to be fine:

I think the recommended instructions should be to just run ./build.sh, which is a lot easier to remember and also breaks less often. It's quite awkward for the installation instructions to be outside of the repository; we should have the website just point to a markdown page or the readme on this repo instead, for anything more complicated than ./build.sh.
