+
+This extension adds support to view and navigate the segments available in the DICOM SEG,
+allowing control over visibility of a given segment and providing metadata about the segment(s).
+
+<!-- TODO: Simple image or GIF? -->
+
+#### Index
+
+Extension Id: `com.ohif.dicom-segmentation`
+
+## Tool Configuration
+
+Tools can be configured through extension configuration using the tools key:
+
+```js
+  ...
+  cornerstoneExtensionConfig: {
+    tools: {
+      ArrowAnnotate: {
+        configuration: {
+          getTextCallback: (callback, eventDetails) => callback(prompt('Enter your custom annotation')),
+        },
+      },
+    },
+  },
+  ...
+```
+
+## Annotate Tools Configuration
+
+*We currently support one property for annotation tools.*
+
+### Hide handles
+This extension configuration allows you to toggle on/off handle rendering for all annotate tools:
+
+```js
+  ...
+  cornerstoneExtensionConfig: {
+    hideHandles: true,
+  },
+  ...
