+# Fedora 40 Images
+
+This set of images is based on the Fedora 40 image.
+It has three flavors, `build`, `test`, and `dev`.
+The first two are primarily intended for automated builds
+and CI usage.
+
+The `build` image contains the compilers and build tools
+needed for building EDK2 under Linux (x86_64).
+
+The `test` image extends the `build` image and adds Qemu for
+testing purposes.
+
+The `dev` image in turn extends the `test` image and adds developer
+convenience tools, for example the git credential manager.
+
+These images include:
+- gcc 14.0.1 (x86, arm, aarch64, riscv, loongarch64)
+- nasm 2.16.01
+- Python 3.12.2
+- Qemu 8.2 (x86, arm, aarch64, loongarch64)
