Lord Adinath Bhagwan (Rishabhdev) is:

• The 1st Tirthankar of the present time-cycle (avasarpini)
• Known as Rishabhdev, Adinath, Adipurush
• His symbol (lanchhan): Bull (Vrishabh)
• Traditional body colour: Golden
• Birthplace: Ayodhya (Ikshvaku dynasty)
• Father: King Nabhiraja
• Mother: Queen Marudevi

Main points of his life in simple words:

• In the beginning of this time-cycle, people did not know how to live, eat, or work properly.
• Bhagwan Adinath taught society:

- how to do farming, trade, arts and crafts - how to wear clothes, cook food, and live in an organized way

• He also established Jain Dharma in this era and created the four-fold sangh:

- Sadhus (monks) - Sadhvis (nuns) - Shravaks (male householders) - Shravikas (female householders)

Later, he renounced everything, did deep tapas and meditation, became Kevaljnani (omniscient), and finally attained Moksha as a Siddha – a completely liberated soul, free from birth and death.

If you tell me what exactly you want (life story, kalyanaks, stavan, icon details, etc.), I can explain that part about Adinath Bhagwan in more detail.
