+
+## Directory Structure
+
+DarkFi broadly follows the standardized unix directory structure.
+
+* All bundled applications are contained in `bin/` subdirectory.
+* Random scripts and helpers such as build artifacts, node deployment
+  or syntax highlighting is in `contrib/`.
+* Documentation is in `doc/`.
+* Example codes are in `example/`.
+* Script utilities are in `script/`. See also the large `script/research/`
+  subdir.
+* All core code is contained in `src/`.
+  See [Architecture Overview](arch/overview.md) for a detailed description.
+    * The `src/sdk/` crate is used by WASM contracts and core code.
+      It contains essential primitives and code shared between them.
+    * `src/serial/` is a crate containing the binary serialization code,
+      which is the same as used by Bitcoin.
+    * `src/contract/` contains our native bundled contracts. It's worth
+      looking at these to familiarize yourself with what contracts on DarkFi
+      are like.
+
+## Using DarkFi
+
+Refer to the main
+[README](https://github.com/darkrenaissance/darkfi/blob/master/README.md)
+file for instructions on how to install Rust and necessary deps.
+
+Then proceed to the [Running a Node](testnet/node.md) guide.
+
+## Join the Community
+
+Although we have a Telegram, we don't believe in centralized proprietary apps,
+and our core community organizes through our own fully anonymous p2p chat system
+which has support for Nym and Tor.
+
+Every Monday at 16:00 CET in #dev we have our main project meeting.
+
+See the guide on [darkirc](misc/ircd/ircd.md) for instructions on joining.
+
+## Contributing as a Dev
+
+Check out the [contributor's guide](dev/contrib/contrib.md) for where to find
+tasks and submitting patches to the project.
+
+If you're not a dev but wish to learn then take a look at the
+[agorism hackers study guide](dev/learn.md).
+
+Lastly familiarize yourself with the [project architecture](arch/arch.md).
+The book also contains a cryptography section with a helpful
+[ZK explainer](crypto/zk_explainer.md).
+
+DarkFi also has a [project spec](spec/crypto-schemes.md) and
+a [DEP](dep/0001.md) (Drk Enhancement Proposals) system.
