 This monorepo contains two sub-projects:
 
-- **ethereum** - [Noir](https://noir-lang.org) library for proving and verifying historical data on the Ethereum blockchain and other EVM compatible blockchains. It supports proving accounts, storage, logs, receipts & transactions. Checkout it's **[docs](./ethereum/README.md)** for more details.
-- **vlayer** - Contains real life examples of what can be built using **ethereum**. It's a work in progress and lacks documentation.

 - Log inclusion
   - Example: _Log number `0` within transaction number `115` in block `N` has `topic0 === 0x...`_
 
+Codebase also includes support for base Ethereum structures in Noir:
+
+- Decoding RLP format
+- Ethereum Merkle Patricia Tries proofs
+- Mappings of Basic Ethereum data types: uint256, address, bytes32, hash
+- Fragment data structure, similar to Rust's slice, used for parsing data
+
 Additionally, we provide [smart contracts](./ethereum/contracts/src/EthereumHistoryVerifier.sol) that allow to verify inclusion of block in the chain for last 256 blocks.

 Noir circuits for proving and verifying historical data on the Ethereum blockchain and other EVMs.
 
-## Monorepo structure
+## Main library content
+
+The main library is available in [lib/](./lib) directory and consists of:
+
+- Generation of proofs for:
+  - [block headers](./get_header/README.md)
+  - [ethereum accounts](./get_account/README.md)
+  - [smart contract storage variables](./get_storage/README.md)
+  - [transaction](./get_transaction/README.md)
+  - [receipts](./get_receipt/README.md)
+  - logs
+- [rlp decoding](./lib/src/rlp/README.md) used by Ethereum to store data
+- [merkle patricia proofs](./lib/src/merkle_patricia_proofs/README.md) - implementation for Ethereum Merkle Patricia tries
+- [fragments](./lib/src/misc/fragment.nr) structure similar to Rust's slice, used for parsing data
+- Basic Ethereum data types:
+  [U256](./lib/src/misc/uint256.nr),
+  [Address](./lib/src/misc/types.nr),
+  [Bytes32](./lib/src/misc/types.nr),
+  [Hash](./lib/src/misc/types.nr), along with util functions.
+
+Additionally, there are binary crates used for recursive proving. See detailed structure in the following section.
