The Communist Manifesto doesn't explain the philosophy of marxism in any meaningful way, it's about the goals of what we would today call a socialdemocratic party, with the important difference that back then such parties were actually intending to implement socialism after reaching said goals. To have a bare minimum of an idea of what was Marx talking about, I'd recommend reading at least "Wage Labour and Capital". Judging from how many strawmans of Marx's take on Labour Theory of Value are out there, I'm fairly sure it can't be guessed from context.
