The developer pages of bitcoin might be a first step: https://bitcoin.org/en/developer-reference#term-raw-format, and then there is also the wonderful book from Andreas „Mastering Bitcoin“, which is also online available...

Every transaction input consists of a number of fields:

  • The txid of the transaction whose output is being spent.
  • The index of the output being spent (also called vout).
  • The scriptSig, or unlocking script.
  • The sequence number.
  • (SegWit inputs only) The scriptWitness.

The first two (txid, vout) are called the outpoint.
