+* Xen does not work in QEMU.  Signing, HOTP, and TOTP do work; see below.
+* Blob requirements are board- or board-family-specific. Check the relevant documentation under `blobs/` for the target you are building.
+* Purism boards use Purism-managed coreboot blob paths from the Purism fork (for example `3rdparty/purism-blobs/...` via `CONFIG_IFD_BIN_PATH` and `CONFIG_ME_BIN_PATH` in `config/coreboot-librem_*.config`). Heads should not maintain those vendor blob payloads. Runtime firmware notes for Librem blob jail are in [blobs/librem_jail/README](blobs/librem_jail/README).
+* Lenovo xx20 boards such as X220 and X230 use the shared xx20 blob flow documented in [blobs/xx20/readme.md](blobs/xx20/readme.md). X220-specific notes are in [blobs/x220/readme.md](blobs/x220/readme.md).
+* Other boards can source blobs from board-family directories under `blobs/` (for example xx20/xx30/xx80, t420, t440p, w541) or from fork-specific paths configured in coreboot configs (for example Dasharo boards using `3rdparty/dasharo-blobs/...`). Vendor blob payloads remain maintained by their upstream vendors/forks.
+* T480 and T480s blob requirements are documented in [blobs/xx80/README.md](blobs/xx80/README.md). Other families have their own docs under `blobs/`, for example `t420/`, `t440p/`, and `w541/`.
