+# Ironforce + Degeon
+
+IronForce is a peer-to-peer decentralized network, Degeon is a messenger built on it.
+
+In this repository there is three Cargo crates and one python project:
+
+- `ironforce` is the decentralized network
+- `degeon_core` contains messenger's protocol
+- `degeon` is the messenger app in Rust + Iced
+- `degeon_py` is a version of the messenger app in Python + Pygame
+
+![](images/dependency_graph.png)
+
 # Ironforce

-IronForce is a decentralized network
+The Ironforce network:
+
+- Has messages encrypted and signed using RSA
+
+- Can build efficient tunnels between two nodes
+
+- Is anonymous: it's very hard to create a connection between a node's IP and its public key
+
+- Can be extended to support any interface, like Bluetooth or even radio
+
+- Can run on ARM microcontrollers
+
+![](images/scheme.png)
+
+### Running IronForce
+
+The `IF` network has a worker daemon that can be used to read the broadcast messages and write them.
+
+Also, you can us `IF` as a Rust library (as it's done in Degeon).
+
+To get started:
+
+1. Clone this repository: `git clone ssh://git@gitlab.ennucore.com:10022/ironforce/ironforce.git`
+2. Install Rust and Cargo. The best way to do this is to use RustUp:
+```shell
+sudo pacman -S rustup    # this is for Arch Linux, on other distros use the corresponding package manager
+rustup default nightly   # this will install rust & cargo (nightly toolchain)
+```
+3. Run the worker:
+```shell
+cd ironforce/ironforce
+cargo build --features std    # This will build ironforce network
+# To run the worker, use this:
+cargo run --bin worker --features std
+```
+
+# Degeon
+
+Degeon is a messenger built on IronForce to show its abilities.
+Its core is in the crate `degeon_core`. The crate can be used as a Python module or in Rust.
+
+To build it, install Cargo and Rust, then do this:
+```shell
+cd ironforce/degeon_core
+cargo build
+```
+
+You will find the `libdegeon_core.so` file that can be used in Python in the `target/debug` directory.
+It should be renamed to `degeon_core.so`. 
+In Windows Rust should generate a `.dll` file that you will be able to use likewise.
+
+There are two GUI options for this interface:
+- A Rust + Iced client (preferred)
+- A Pygame client
+
+To run the Rust client, `cd` into the `degeon` folder of this repository, then use cargo:
+`cargo run`. 
+Note: this application requires Vulkan to be installed. 
+For me on Arch Linux and Intel GPU the installation command was `sudo pacman -S vulkan-intel`.
+On most systems it should be pre-installed.
