Marx did use the phrase commonly translated "dictatorship of the proletariat." But he certainly did not publish a plan for how to achieve it.
He did the exact opposite, he explained why he thought such a plan should not be published.
> Can it be, you only heard of the capital, but not the communist Manifest?
The Communist Manifesto -- which is a statement of the Communist Party rather than Marx, though he wrote it -- includes a political platform, but read the platform and you see, it is mostly just social democratic reforms. At most, it approaches "revolutionary reform" (i.e., reforms meant to make revolution possible). It certainly isn't a description of the "dictatorship of the proletariat." You won't ever find that and cite it.
