The Book of Acts describes the birth and spread of the Christian congregation from its humble beginnings in Jerusalem until Paul reached the city of Rome. The book is written by Luke, a friend and traveling companion of Paul (Col 4:14, 2 Tim 4:11a).
When the text says "we", Luke is among them along with Paul. When it says "they", he isn't. It's a direct continuation of the Gospel of Luke, see The Four Gospels.
This book is all about the work of the Holy Spirit among believers.
The reason for this is that the Holy Spirit is mentioned 56 times in this book.
