+| `tfogo_checklinkname0`             | :material-check:     | Companion to `badlinkname`. Go 1.23+ enforces `go:linkname` restrictions via the linker; this tag signals the build uses `-checklinkname=0` to bypass that enforcement.                                                                                                                                                       |
 
 It is not recommended to change the default build tag list unless you really know what you are adding.
 
+## :material-wrench: Linker Flags
+
+The following `-ldflags` are used in official builds:
+
+| Flag                                                        | Description                                                                                                                                                                                                             |
+|-------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `-X 'internal/godebug.defaultGODEBUG=multipathtcp=0'`      | Go 1.24 enabled Multipath TCP for listeners by default (`multipathtcp=2`). This may cause errors on low-level sockets, and sing-box has its own MPTCP control (`tcp_multi_path` option). This flag disables the Go default. |
+| `-checklinkname=0`                                          | Go 1.23+ linker rejects unauthorized `go:linkname` usage. This flag disables the check, required together with the `badlinkname` build tag.                                                                            |
+
+## :material-package-variant: For Downstream Packagers
+
+The default build tag lists and linker flags are available as files in the repository for downstream packagers to reference directly:
+
+| File | Description |
+|------|-------------|
+| `release/DEFAULT_BUILD_TAGS` | Default for Linux (common architectures), Darwin, and Android. |
+| `release/DEFAULT_BUILD_TAGS_WINDOWS` | Default for Windows (includes `with_purego`). |
+| `release/DEFAULT_BUILD_TAGS_OTHERS` | Default for other platforms (no `with_naive_outbound`). |
+| `release/LDFLAGS` | Required linker flags (see above). |
+
 ## :material-layers: with_naive_outbound
 
 NaiveProxy outbound requires special build configurations depending on your target platform.
