Weâ€™ve been busy working on technical documentation to share with you on best practices for Custom Content and Mods and details about how the game works. Weâ€™re happy to announce that this can now be found here: TS4_Custom_Content_Guide.zip
The Sims 4 is a large game, so we canâ€™t document everything about it, but weâ€™ve included information about a few key things we thought youâ€™d appreciate.
We hope this accelerates your progress. Please continue to ask questions in the forums, and we will do our best to answer them.
For updates and discussion see that thread and/or the sticky in Modding Discussion â€“ locking this one so we donâ€™t have two parallel threads.
