**Very well done Felix!**

Duuuuude! Commands below `panic!`

_Your code_:
```rs
let args = std::env::args()/*...*/;
match args[1]/*...*/ {
"set_database" => {
if args.len() > 2 {
panic!("[FATAL ERROR]: Too many arguments!");
} else if args.len() < 2 {
panic!("[FATAL ERROR]: Not enough arguments!");
}
overwrite_default(args[2].clone()).ok().unwrap();
//...
},
//...
"insert" => {
if args.len() > 3 {
panic!("[FATAL ERROR]: Too many arguments!");
} else if args.len() < 3 {
panic!("[FATAL ERROR]: Not enough arguments!");
}
db.add_value(str_to_hash(args[2].clone().as_str()), args[3].clone());
//...
}
"delete" => {
if args.len() > 2 {
panic!("[FATAL ERROR]: Too many arguments!");
} else if args.len() < 2 {
panic!("[FATAL ERROR]: Not enough arguments!");
}
db.remove_value(str_to_hash(args[2].clone().as_str()));
//...
}
"show" => {
if args.len() > 2 {
panic!("[FATAL ERROR]: Too many arguments!");
} else if args.len() < 2 {
panic!("[FATAL ERROR]: Not enough arguments!");
}
let values = db.find_values(str_to_hash(args[2].clone().as_str()));
//...
}
//...
}
```

Your code would certainly benefit from some proper documentation, since it would ease your referencing in the future.

The issue names no files, tests, or documentation target. Start by locating the Rust CLI entry point that matches set_database, insert, delete, and show, then inspect how their arguments and database operations work. Done is not defined; clarify which commands and documentation format must be covered before starting.
