Basic instructions — how to run example or custom program

[merwok]

Hello! Minimum instructions to build and try this repo:

1. mkdir build && cd build
2. cmake .. && make
3. copy or symlink a lua file (for example ../examples/snake.lua) as main.lua
4. run ./32blit_lua

This could be added to the README.

Agreed. You can even specify a launch path to avoid having to copy or symlink the file:

./32blit_lua --help
Lua v0.0.3
Powered by 32Blit SDL2 runtime - github.com/32blit/32blit-sdk

Usage: ./32blit_lua <options>

 --connect <addr>     -- Connect to a listening game instance.
 --listen             -- Listen for incoming connections.
 --position x,y       -- Set window position.
 --launch_path <file> -- Emulates the file associations on the console.   <--- Here!
 --credits            -- Print contributor credits and exit.
 --info               -- Print metadata info and exit.
