+### Abandoned packages
+
+To enable your satis installation to indicate that some packages are abandoned, add the following to your `satis.json`:
+
+```json
+{
+    "abandoned": {
+        "company/package": true,
+        "company/package2": "company/newpackage"
+    }
+}
+```
+
+The `true` value indicates that the package is truly abandoned while the `"company/newpackage"` value specifies that the package is replaced by
+the `company/newpackage` package.
+
+Note that all packages set as abandoned in their own `composer.json` file will be marked abandoned as well.
