**d7.01.01** Develop a new order
=============================================

**Summary:**

This document complements the development training presentations.
It details the steps required to complete the addition exercise
of a new order.

We propose to create a new command that allows the translation of a mesh
of a 2D or 3D vector.

The objective is to know:

- write the order catalog;
- use the routines for querying keywords from Fortran;
- use utility routines from the Jeveux memory manager;
- extract information from a data structure using existing utilities;
- build and test its development.


**Note:**

    The essential prerequisites before starting to develop is to know:

    - the Fortran,
    - Python (including Object Oriented Programming),
    - the Git version manager,
    - the GitLab interface.

    A skeleton of the required files is provided during the training in order to
    to guide new developers.

    It is recommended to start with :ref:`d7.01.01-build-ref`, then
    The :ref:`d7.01.01-build-branch`.
