+## apoxy delete
+
+Delete resources by file or type/name
+
+### Synopsis
+
+Delete resources identified in file(s), directories, stdin, or by type and name.
+
+Supports two modes:
+  1. File-based: delete resources specified in YAML/JSON files, directories, or stdin.
+  2. Type+name: delete one or more resources by specifying the resource type and name(s).
+
+When a directory is specified with -f, all .yaml, .yml, and .json files are processed.
+
+Examples:
+  # Delete resources in a single file
+  apoxy delete -f gateway.yaml
+
+  # Delete resources in multiple files
+  apoxy delete -f gateway.yaml -f routes.yaml
+
+  # Delete all resources in a directory
+  apoxy delete -f ./manifests/
+
+  # Delete from stdin
+  cat manifest.yaml | apoxy delete -f -
+
+  # Delete a resource by type and name
+  apoxy delete proxy my-proxy
+
+  # Delete multiple resources by type and name
+  apoxy delete backend backend-a backend-b
+
+  # Delete a resource, ignoring if it doesn't exist
+  apoxy delete proxy my-proxy --ignore-not-found
+
+  # Delete and wait for the resource to be fully removed
+  apoxy delete proxy my-proxy --wait
+
+```
