How to worship Shaligram Shila/ Shaligram Puja Vidhi
        The mantras
        
        There are 16 upacaras (items of offering), thus there are 16 offering               mantras. Below is a list of 20 mantras. This list contains more than               16 only because there are some repetitions. What this list shows is               the order in which the upacaras are offered during the puja; accordingly,               acamana (purification of the mouth) is offered at 3 different times               (after the first time the acamana mantra changes to idam punaracamaniyam,               "We should again offer acamana.") Also, at the end an offering               of sarvam (all upacaras) is made to conclude the puja to each worshipable               personality. In this way, though there are only 16 upacaras, in the               course of my puja we must chant 20 offering mantras.

Outline of the steps of worship
        
At the start, We should do a preliminary acamana, chanting the om               apavitra verse and doing pranayama mudra 
We must offer obeisances and wake Their Lordships 
Offering prayers to the spiritual master (Sri Guruvastakam etc.) and               Panca-tattva and Hare Krsna mahamantras we should clean the altar,               change the Deities' water, set up the puja items 
Full acamana (om kesavaya manah etc.), visnu smaranam, mangala santi,               bhuta-suddhi, obeisances, om apavitra acamana with pranayama mudra.
       With mantras and sprinkling of water we must               draw a protective circle around the place of puja, show khadga-mudra               for dig-bandha (closing the directions), and purify everything within               the circle with Nrsimha-mantra. 
Worship of Ananta-Nrsimha Deity and Nrsimha-sila (bathing, cloth,               ornaments, gandha, throne, offering everything, chant Nrsimha-gayatri,               arati of dhupa-dipa-puspa while chanting Nrsimha prayers. This is               done with mantra-mudra. 
Worship of Srila Prabhupada with all upacaras except tulasi and mala               which will be presented later to HDG as prasadam. The whole worship               is done with mantra-mudra.
       Worship of Gauranga, 16 upacaras with mantra-mudra. 
Worship of Sri-Sri Jagannatha-Sudarsana silas. This is the main worship.               16 upacaras are offered. Most are mantra-mudra offerings except for               naivedya. Tulsi and puspa offered to feet of SSJS silas during the               offering of these upacaras; more tulsis and flowers are offered to               all silas at the conclusion of the worship.
