The DECA Project Documentation


A general DECA protocol specification and some example use cases.


There are some requirements you need to fulfill to be able to work with DECA docs.

  • Rust >= 1.66
  • curl >= 7.88.1
  • cargo >= 1.72.0
  • mdBook >= v0.4.34
  • git >= 2.39.2

NOTE: These are the recommended versions since they were tested in the development environment.


The easiest way to get both Rust and Cargo's latest versions is by using the rustup script, which also means that you have to use the curl command.

1. Git Installation.

The first step is to install git on you Unix system. To do that, you only need to run the following command:

$ sudo apt install git

2. Curl Installation.

You have to repeat the same proccess to install curl, use the apt command:

 $ sudo apt install curl

Once you have curl installed you can go ahead and continue with the Rust and Cargo installations.

3. Rust and Cargo Installation.

To install Rust and Cargo on your Unix System you have to download the rustup installer script using the following command on the terminal:

$ curl --proto '=https' --tlsv1.2 -sSf | sh

By using the previous command you will get the latest Rust and Cargo's versions.

Suggestion: You can make sure the installation was succesfull by using the following command:

$ rustc --version

It tells you the version of Rust that was installed.

NOTE: Some important considerations when installing Rust:

  • When you install Rust, it will be installed only for the current user, in other words, the installation is not system-wide.

  • It is not required to be root or sudo to be able to install Rust.

Once you have completed your Rust and Cargo installations, you can now continue with the mdBook installation.

4. MdBook Installation.

DECA Docs uses mdBook as a way to create books with Markdown. Since mdBook is a command line tool, it is ideal for creating tutorials, API documentations, course materials, amongst other useful things.

You can follow the instructions bellow to download mdBook.

First, you have to use the following command to build and install mdBook:

$ cargo install mdbook

The command will automatically download mdBook, build it and install it in Cargo's global binary directory.

Once installed, the next step is to get the DECA Docs repository. Follow the instructions below to get it.

Clone the DECA Documentation repository.

After you have succesfully compleated all installations, you can now access the docummentation repository and contribute to the resources. Run the next command on the terminal:

$ git clone
  • This command lets you copy the DECA Docs repository to your local machine.
  • It also means that you can pull down a full copy of all the repository data that it has at that point in time, including all versions of every file and folder for the project.

Once the repository has been cloned, you can have access to it by entering the following command on your terminal:

$ cd docs/

This command will lead you to the directory where you can find the DECA Docs

The last step is to run the server using the following command:

$ mdbook serve 

You can view the page on any browser using the following link

NOTE: If you want to access remotely use the mdbook serve -n which means any IP address can access the DECA Docs project.
