+# oh hello you have found my vile creation
+
+### todos
+- proper error handling
+- clean up the code in general (can you tell it's bad)
+- use a hasher per thread
+- special handling for media: we want to hash it based on pixels, not raw bytes.
+- transcoding support for images (post image -> store webp -> send back jpg/webp/png depending on need)
