+## GRPC Maximum message size
+
+Ocis is using grpc for inter service communication. When having a folder with a lot of files (25000+, size doesn't matter) and doing a `PROPFIND` on the folder, the server will run into errors because the
+grpc message body gets to big. We introduced the envvar `OCIS_GRPC_MAX_RECEIVED_MESSAGE_SIZE` to raise the max size for the grpc body.
+
+NOTE: With a certain amount of files even raising the grpc message size will not suffice as the requests will run into network timeouts. Also generally the more files are in a folder, the longer it will take to load.
+
+It is recommended to use `OCIS_GRPC_MAX_RECEIVED_MESSAGE_SIZE` only temporary to copy files out of the folder (e.g. via web ui) and use the default value in general.
