+# Versions of Libra SDK
+
+## Why do we need these?
+Transactions submitted to blockchain are done in bytecode. Decoding that bytecode into a useful object (function name, arguments, timestamp) is hard to do if you do not have the Rust serialization lib which generated the bytecode originally.
+
+The names of functions (and some primitives like Account Address), change between versions.
+
+Suppose you would like to analyze a V5 transaction. Without these files you'll have to guess the transaction type and craft an individual decoder.
+
+# Modifications to originals
+Note that these files are code generated, and were not intended to be changed. We have however added serde De/Serialize attributes to the EntryFunctionCall, so that they can be easily be read into memory.
