   Only a few excerpts of the text, because it's a long guide:
   # What is Particl?

   To sum it up briefly, Particl is a privacy-focused blockchain/P2P
   hybrid ecosystem that will host a decentralized and anonymous
   marketplace as well as an array of Dapps using a native
   cryptocurrency.

   <SNIP>

   Particl is the successor of the ShadowProject
   ([3]https://shadowproject.io/en), a privacy-focused cryptocurrency
   project started back in August 2014. The team behind this project are
   known for being innovators in the cryptocurrency scene, being the first
   to produce many feats such as an HTML5 wallet, a staking mobile wallet
   with encrypted messaging and transactions, as well as having the first
   ring signature and HD wallet implementation on BTC codebase. Their
   Umbra graphical wallet, built using HTML5, is widely known in the
   “altcoin” community for being absolutely gorgeous and very
   user-friendly.
