 Eden is not currently available as a port on FreeBSD, though it is in the works. For now, the recommended method of usage is to compile it yourself.
 
 The available OpenSSL port (3.0.17) is out-of-date, and using a bundled static library instead is recommended; to do so, add `-DYUZU_USE_BUNDLED_OPENSSL=ON` to your CMake configure command.
+
+## NetBSD
+
+System provides a default `g++-10` which doesn't support the current C++ codebase; install `clang-19` with `pkgin install clang-19`. Then build with `cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -B build`.
+
+Make may error out when generating C++ headers of SPIRV shaders, hence it's recommended to use `gmake` over the default system one.

+Install `pkgin` if not already `pkg_add pkgin`, see also the general [pkgsrc guide](https://www.netbsd.org/docs/pkgsrc/using.html). For NetBSD 10.1 provide `cat 'PKG_PATH="https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/x86_64/10.0_2025Q3/All/"' >/etc/pkg_install.conf`. If `pkgin` is taking too much time consider adding the following to `/etc/rc.conf`:

+cd glslang
+python3.13 ./update_glslang_sources.py
