+### Agent Registry 
+
+#### Agent Metadata Schema
+
+Dapr Agents utilizes an agent registry (often referenced as `agent-registry` statestore) to communicate agent capabilities. The agent registry contains agent metadata, including the agent's name, description, version and more. 
+
+In order to facilitate easier handling of version changes to the agent metadata, Dapr Agents supplies versioned JSON schemas. Within the agents repository you'll find 3 types of JSON schema files:
+
+- [index.json](https://raw.githubusercontent.com/dapr/dapr-agents/main/schemas/agent-metadata/index.json)
+- [latest.json](https://raw.githubusercontent.com/dapr/dapr-agents/main/schemas/agent-metadata/latest.json)
+- `v{version}.json`
+
+The `index.json` can be used as a lookup table and looks like:
+
+```
+{
+  "current_version": "X.Y.Z",
+  "schema_url": "https://raw.githubusercontent.com/dapr/dapr-agents/main/schemas/agent-metadata/vX.Y.Z.json",
+  "available_versions": [
+    "vX.Y.Z",
+    "vA.B.C"
+  ]
+}
+```
+
+When the agent starts up it will insert its own metadata into the supplied agent registry. The agent metadata object contains the key `schema_version` which can be used as a reference to fetch the valid schema for that agent version:
+
+```sh
+curl -s -v "https://raw.githubusercontent.com/dapr/dapr-agents/main/schemas/agent-metadata/v$(jq -r '.schema_version' agent-metadata.json).json"
+```
