@reylejano What a funny coincidence! I was just about to refine the wording further when the previous PR got merged. Would you mind reviewing this new PR again?

Introducing the .env file abruptly could cause confusion for users. I’ve updated its title to Env File Syntax and clarified that this section’s specifications are derived from the .env file (which is commonly used in environment configuration).
