+# qemu virtual machines builder
+
+This directory contains some bash scripts for building qemu-based vm images.
+We can use these vm environments for generating FlashCap V4L2 interop fragments.
+
+* `build-virt-images.sh`:
+  Construct virt-manager based Debian 12 vm images for `x86_64`, `i686`, `aarch64` and `armv7l` architectures.
+* `build-mipsel-image.sh`:
+  Build Debian 12 vm image for `mipsel` architecture.
+* `run-mipsel-image.sh`:
+  Run Debian 12 vm image for `mipsel` architecture.
