The Corda repository comprises the following folders:

• buildSrc contains necessary gradle plugins to build Corda
• client contains libraries for connecting to a node, working with it remotely and binding server-side data to JavaFX UI
• confidential-identities contains experimental support for confidential identities on the ledger
• config contains logging configurations and the default node configuration file
• core containing the core Corda libraries such as crypto functions, types for Corda's building blocks: states, contracts, transactions, attachments, etc. and some interfaces for nodes and protocols
• docs contains the Corda docsite in restructured text format
• experimental contains platform improvements that are still in the experimental stage
• finance defines a range of elementary contracts (and associated schemas) and protocols, such as abstract fungible assets, cash, obligation and commercial paper
• gradle contains the gradle wrapper which you'll use to execute gradle commands
• lib contains some dependencies
• node contains the core code of the Corda node (eg: node driver, node services, messaging, persistence)
• node-api contains data structures shared between the node and the client module, e.g. types sent via RPC
• samples contains all our Corda demos and code samples
• testing contains some utilities for unit testing contracts (the contracts testing DSL) and flows (the mock network) implementation
• tools contains the explorer which is a GUI front-end for Corda, and also the DemoBench which is a GUI tool that allows you to run Corda nodes locally for demonstrations
• verifier allows out-of-node transaction verification, allowing verification to scale horizontally
• webserver is a servlet container for CorDapps that export HTTP endpoints. This server is an RPC client of the node
