# RDK Official Resource Index

> Sources: D-Robotics official docs and GitHub. Index of official docs/resources grouped by topic; pair with WebFetch to confirm the latest version.

> **Doc site split (2026):** the merged `rdk_doc` repo was split into independent sites — X-series → `rdk_x_doc`, S-series → `rdk_s_doc`, TROS → `tros_doc`, Model Zoo → `model_zoo_doc`, RDK Studio → `rdk_studio_doc`, accessories → `accessories_doc`. Legacy `developer.d-robotics.cc/rdk_doc/...` links still resolve (with a "migrated" banner). **To pin a question to the exact chapter/URL on the new sites, use the `rdk-doc-finder` skill** (full topic→URL index + URL derivation rules).
