+# BSD Vagrant Test Environments
+
+This directory contains Vagrant configurations for testing across multiple BSD operating systems.
+
+Use the `build_fish_on_bsd.sh` script to automatically build fish-shell on multiple BSD VMs:
+
+```bash
+./build_fish_on_bsd.sh freebsd_14_0 openbsd_7_4 netbsd_9_3 dragonflybsd_6_4
+```
+
+The script will:
+
+- Boot each VM
+- Sync the latest files
+- Run `cargo build` in `/sync/fish-shell`
+- **Halt VMs that build successfully**
+- **Leave VMs running if builds fail** (for debugging)
+- Show a summary of successes and failures
