how to publish php package so it will download `”name/mypackage”: “dev-build”`

I have the access of a PHP Package called “name/mypackage”,

and in my local computer system there is a file called composer.json that looks like this,

{
    "require": {
        "name/mypackage": "dev-build"
    }
}

when i run composer install

it will show me this error Problem 1 - Root composer.json requires name/mypackage dev-build, found name/mypackage[dev-main] but it does not match the constraint.

So my question is what version should i use in publicly available name/mypackage package’s composer.json file

{
    "name": "name/mypackage",
    "version": "<WHAT_SHOULD_I_USE_HERE_SO_IT_WILL_DOWNLOADS_IN_MY_COMPUTER>",
    "description": "PHP Package",
    "type": "library",
    "license": "MIT",
    "authors": [
        {
            "name": "sachin"
        }
    ]
}

Thank You
