To get us started, I'll try to document my building of a Necron pylon. First things first: you'll need to verify you've got all the bits in the kit, clean the pieces using cold soapy water, straighten any bended bits with warm water, and remove the extra bits of resin, using a combination of saw, Dremel, and sand paper (usual warnings apply: resin is toxic, wear a mask and protect your eyes). In the pictures below I've marked in purple all the bits to be removed. Note: I start with the cleaning and then do the sanding, and have not had any issues with peeling paint. Others will prefer to sand first and clean later.
