+## CMX Fragments
+
+This directory contains the cmx fragments that are required for running
+Fuchsia tests hermetically. Tests start from `minimum_capabilities.test-cmx`
+and add additional capabilities as necessary by providing the
+`additional_manifest_fragments` argument. Some fragments are explained in detail
+below:
+
+### General Purpose Fragments
+
+#### font_capabilities.test-cmx
+For tests that test fonts by providing `fuchsia.fonts.Provider`.
+
+#### jit_capabilities.test-cmx
+Required by tests that execute JavaScript. Should only be required in a small
+number of tests.
+
+#### minimum_capabilites.test-cmx
+Capabilities required by anything that uses `//base/test`, used as the base
+fragment for all test suites.
+
+#### read_debug_data.test-cmx
+Required by tests that need access to its debug directory. Should only be
+required in a small number of tests.
+
+#### test_logger_capabilities.test-cmx
+For tests that test logging functionality by providing `fuchsia.logger.Log`.
+
+### WebEngine Fragments
+The following fragments are specific to WebEngine functionality as documented
+documentation at
+https://fuchsia.dev/reference/fidl/fuchsia.web#CreateContextParams and
+https://fuchsia.dev/reference/fidl/fuchsia.web#ContextFeatureFlags.
+Any test-specific exceptions are documented for each file.
+
+#### audio_capabilities.test-cmx
+Corresponds to the `AUDIO` flag. Required for enabling audio input and output.
+
+#### network_capabilities.test-cmx
+Corresponds to the `NETWORK` flag. Required for enabling network access. Note
+that access to the root SSL certificates is not needed if ContextProvider is
+used to launch the `Context`. The `fuchsia.device.NameProvider` dependency comes
+from fdio.
+
+#### present_view_capabilities.test-cmx
+Services that are needed to render web content in a Scenic view and present it.
+Most services are required per the FIDL documentation.
+`fuchsia.ui.policy.Presenter` is additionally required by tests that create
+views.
+
+#### vulkan_capabilities.test-cmx
+Corresponds to the `VULKAN` flag. Required for enabling GPU-accelerated
+rendering of the web content.
+
+#### web_engine_required_capabilities.test-cmx
+Contains services that need to be present when creating a
+`fuchsia.web.Context`. Note that the `fuchsia.scheduler.ProfileProvider` service
+is only used in tests that encounter memory pressure code.
+
+#### web_instance_host_capabilities.test-cmx
+Contains services that need to be present to use `WebInstanceHost`.
