 Version attributes, such as `service.version`, are values of type `string`. They are
 the exact version used to identify an artifact. This may be a semantic version, e.g., `1.2.3`, git hash, e.g.,

+[Cloud](./cloud.md) and below. Provider-specific attributes all reside in the `cloud_provider` directory.
+Valid cloud providers are:

+# AWS Semantic Conventions
+
+This directory defines standards for resource attributes that only apply to Amazon
+Web Services (AWS) resources. If an attribute could apply to resources from more than one cloud
+provider (like account ID, operating system, etc), it belongs in the parent
+`semantic_conventions` directory.
+
+## Generic AWS Attributes
+
+Attributes that relate to AWS or use AWS-specific terminology, but are used by several
+services within AWS or are abstracted away from any particular service:
+
+- [AWS Logs](./logs.md)
+
+## Services
+
+Attributes that relate to an individual AWS service:
