Microchip’s official documentation is dense. The MPLAB XC8 PIC Assembler User’s Guide (DS50002974) isn’t light reading, but it is the definitive source for:

command-line driver to build assembly projects for 8-bit PIC microcontrollers. Microchip Technology Key Documentation Links Main User's Guide (DS50002974): The comprehensive guide covering PIC Assembler Driver Options , assembly-level instructions, and toolchain integration. Guide for Embedded Engineers (DS50002994): A "getting started" manual that provides example projects and common coding sequences for developers new to this specific assembler. Migration Guide (DS50002973): Essential for those migrating older MPASM projects

Before diving into the technicalities, it is worth asking: Why consult the Assembler User’s Guide when C is the industry standard? and file registers.

The standalone MPASM tool is deprecated. The assembler is now integrated into the MPLAB XC8 compiler (v2.00 and later).

MPLAB X provides an integrated simulator and hardware debuggers like the PICkit or ICD series. When debugging XC8 assembly, you can step through code instruction by instruction, observing the exact state of the Working Register, Status bits, and file registers.
