+first you should build bls as described above
+
+when you run `zig build test`, the spec tests are not run by default.
+
+if you want to run spec tests, you need to download the test vectors and add `-Dspec=true` to the zig build command.
+
+```bash
+# download test vectors
+make deps_test
+# add -Dspec=true to run spec tests
+zig build test -Dspec=true
