The file structure of the [Mina repository](https://github.com/minaprotocol/mina)the roles various files play:

- `dockerfiles/`
   Contains Docker-related scripts

- `docs/`
   Documentation for the code and processes for contributing are here. The documentation website with the walkthrough docs lives in `frontend/website/docs`.

- `frontend/`
   All code related to Mina frontend UIs and products

  - `wallet/`
     Source code for the Mina wallet

  - `website/`
     Code for https://minaprotocol.com

    - `posts/`
       Markdown docs for blog posts

    - `src/`
       Source code for the website

    - `static/`
       Static files like images, etc.

- `rfcs/`
   This directory contains all accepted RFCs (or "requests for comments") made according to the [RFC process](https://github.com/MinaProtocol/mina/blob/master/CONTRIBUTING.md#rfcs).

- `scripts/`

- `src/`
   All protocol source code, both application and library code, is in this directory.

  - `*.opam`
     These files are needed for our `dune` build system. There must be one for each
    library in `lib`. When you create a library `lib/foo_lib` with a `dune` file giving
    the library's name as `foo_lib`, you must create a `foo_lib.opam` file.

  - `config/`
     Build time config - these .mlh files define compile time constants and their values.

  - `app/`
     Applications live here.

    - `cli/`
       This is the mina client/daemon. It is what you use to run a staker, a snarker, or a simple client for sending and receiving transactions.

    - `website/`
       Soon to be deprecated directory for the website - most of the code has migrated over to `frontend/website/`

    - `reformat/`
       This program runs `ocamlformat` on most of the files in the source tree, with a few exceptions.

    - `logproc/`
       This utility reads from `stdin` and can filter and pretty print the log messages emitted by the mina daemon.

    - `libp2p_helper/`
       This program uses go-libp2p to implement the peer-to-peer plumbing that Mina daemons need.

  - `external/`
     Local copies of external libraries which we've had to make some tweaks to.

  - `lib/`
     Libraries powering mina.
    The libraries here basically fall into two categories.
    1. General purpose data-types and functionality. This includes `snarky`, `fold_lib`, `vrf_lib`, `sgn`, and others.
    2. Application specific functionality, structured as a library. This includes `syncable_ledger`, `staged_ledger`, `transaction_snark`, and others.
