The latest version (3.1.1) is a pre-alpha release for Factorio 2.0, requiring a development version of Nullius. Use the stable release (2.3.1) to play with Factorio 1.1.

Lambent Nil extends Nullius with phosphorus, a new resource that lends its own character to Nullius's style of richly interacting intermediates. Use traces of phosphorus in vacuum chambers, a precursor to nanotechnology, to manufacture silicon circuits. Upgrade your industrial processes after researching boron doping and electron beams. Use phosphate to synthesize and feed new life.

Concentrated sources of phosphorus are hard to find. Fortunately, your factory only needs small amounts initially. As the factory expands, you will need to supplement the limited ore supply with phosphate recovered from limestone, industrial waste, and biological waste.

If you are looking for an additional challenge, enable the Fluorapatite mod setting. Phosphorite will yield both phosphorus and fluorine. Fluorine is used in refrigerant and fluoropolymers. Fluorine merits careful management, as its production and disposal are coupled to other resource streams.

For Nullius players: This mod should be played as a new game, because it adds a new ore and modifies some of Nullius's recipes. The early game is unchanged until silicon ingot production.
