Rules
The full rules for playing Dungeons and Dragons in Eberron come in the Dungeons & Dragons Player’s Handbook, and Eberron: Rising from the Last War. These are probably available from some local bookshops or gaming shops, or to order online from Book Depository, but you won’t need them:
If you don’t want to buy them, or they’re too long to read, then everything you need except for some of the character classes and races are in the Basic Rules.
Errata are collected in the Player’s Handbook Errata, and help with rules interpretations in the Sage Advice Compendium.
