+# Eth 2.0 test vectors generators
+
+Test vectors generators based on the specifications at https://github.com/ethereum/eth2.0-specs.
+
+## Implementation
+
+As much as possible the generators copy-paste the specifications. If an example implementation
+is not available in the specifications, the generator will be implemented using one of the
+Ethereum Foundation library instead.
+
+## License
+
+Similar to Eth 2.0 specifications, all code and generated test vectors
