+A RocksDB backend for Mnesia.
 
 This permits Erlang/OTP applications to use RocksDB as a backend for
 mnesia tables. It is based on Klarna's `mnesia_eleveldb`.

+
+An `on_write_error_store` option can be provided, per-table, in the `rocksdb_opts`
+user property (see [Customization](#customization) above).
+When set, the backend will use the value of the option as the name for an ETS table
+which is used as storage for runtime write errors. The table must be set up outside
+of the backend by the clients themselves.
+
+Entries to the table are in the form of a tuple `{{Table, Key}, Error, InsertedAt}`
+where `Table` refers to the Mnesia table name, `Key` is the primary key being used by Mnesia,
+`Error` is the error the backend encounteredA and `InsertedAt` refers to the time
+the error was encounterd as system time in milliseconds.
+
+The backend will only insert entries and otherwise not managed the table. Thus, clients
+are expected to clean up the table during runtime to prevent memory leakage.

 ## Caveats
 
 Avoid placing `bag` tables in RocksDB. Although they work, each write
