-Requires Go 1.24.13+, GCC, and libpcap development headers
-(install with `apt install build-essential libpcap-dev` on Debian/Ubuntu/Kali,
-or `yum install gcc libpcap-devel` on RHEL/CentOS, or `brew install libpcap` on macOS).
-
-The libpcap headers are only needed by the `sniff` and `split` tools - if
-libpcap is missing, `install.sh` will skip those two and build the rest.
+The default (`--target native`) build needs Go 1.24.13+, GCC, and libpcap
+development headers (`apt install build-essential libpcap-dev` on
+Debian/Ubuntu/Kali, `yum install gcc libpcap-devel` on RHEL/CentOS, or
+`brew install libpcap` on macOS). The `portable` and `windows` targets only
+need the Go toolchain; `sniff` and `split` become stubs in those builds
+because they require libpcap. See [Platform Support](#platform-support) for
+the full matrix.
