No, but here are some links with information.

It looks Indian based, probably an offshoot from Hinduism.

It is a subset, a derivation of Vedic Dharm or Hinduism.

Some of its followers, the Digambers, walk around in the nude.

yes, i m Jain...Jainism is an ancient religion of India that prescribes a path of non-violence towards all living beings. Its philosophy and practice emphasize the necessity of self-effort to move the soul towards divine consciousness and liberation.
Jainism is also referred to as Shraman (self-reliant) Dharma or the religion of Nirgantha (who does not have attachments and aversions) by ancient texts. Jainism is commonly referred to as Jain Dharma in Hindi and Samanam in Tamil.
Core beliefs:
*Every living being has a soul.
*Every soul is potentially divine, with innate qualities of infinite knowledge, perception, power, and bliss (masked by its karma's).
*Regard every living being as you do yourself, harming no one and being kind to all living beings.
Every soul is born as a heavenly being, human, sub-human or hellish being according to its own karma's.
*Every soul is the architect of its own life, here or hereafter.
*When a soul is freed from karma's, it becomes free and attains divine consciousness, experiencing infinite knowledge, perception, power, and bliss.
*Right Faith (right vision), Right Knowledge and Right Conduct (triple gems of Jainism) provide the way to this realization.There is no supreme divine creator, owner, preserver or destroyer. The universe is self-regulated and every soul has the potential to achieve divine consciousness (Buddha) through its own efforts.
*Navakar Mantra is the fundamental prayer in Jainism and can be recited at any time of the day. Praying by reciting this mantra, the devotee bows in respect to liberated souls still in human form (Arihantas), fully liberated souls (Siddhas), spiritual leaders (Acharyas), teachers (Upadyayas) and all the monks (sarva sadhus). By saluting them saying "namo namaha", Jains receive inspiration from them to follow their path to achieve true bliss and total freedom from the karmas binding their souls. In this main prayer, Jains do not ask for any favours or material benefits. This mantra serves as a simple gesture of deep respect towards beings who are more spiritually advanced. The mantra also reminds followers of the ultimate goal of reaching nirvana or moksha.
*Non-violence (to be in soul consciousness rather than body consciousness) is the foundation of right view, the condition of right knowledge and the kernel of right conduct. It leads to a state of being unattached to worldly things and being nonjudgmental and non-violent; this includes compassion and forgiveness in thoughts, words and actions toward all living beings and respecting views of others (non-absolutism).
*Four things are difficult for a soul to attain: 1. human birth, 2. knowledge of the laws governing the souls, 3. absolute conviction in the philosophy of non-violence and 4. practicing it in every day life activities.
*It is therefore important not to waste human life in evil ways. Rather, strive to rise on the ladder of spiritual evolution.
*The goal of Jainism is liberation of the soul from the negative effects of unenlightened thoughts, speech and action. This goal is achieved through clearance of karmic obstructions by following the triple gems of Jainism.
*Jains worship the icons of Jinas, Arihants and Tirthankars, who have conquered the inner passions and attained divine consciousness, and study the scriptures of these liberated beings.
Jainism acknowledges the existence of powerful heavenly souls (Yaksha and Yakshini) that look after the well beings of Thirthankarars. Usually, they are found in pair around the icons of Jinas as male (yaksha) and female (yakshini) guardian deities. Even though they have supernatural powers, these deities are also souls wandering through the cycles of births and deaths just like most other souls. Over time, people started worshiping these deities as well.

Jainism and Buddhism are similar as answered before.

Jainism was started by the mercantile class of people whereas Buddhism was started by kingly administrative class of people. Both of them revolted against the rabbinical class some of them were exploiting the other lower subordinate classes.
