+How to contribute
+#################
+
+OhmPi is an open source system and contributions in terms of hardware and software are welcome. However, in order to
+maintain the project on tracks and promote exchange and reuse, it is necessary that contributors
+wishing to develop new software or hardware components follow a few basic steps detailed below.
+Contributors are also kindly asked to get in touch with the OhmPi developing team.
+
+Developing hardware components
+******************************
+Here is a non exhaustive wish list of new hardware features that are planned/hoped to be developed in the future.
+Contributors are welcomed to  join forces to make this list come true, or propose new ideas by creating a new issue in the Gitlab repository.
+
+Wish list of hardware developments:
+- Automatic selection of shunt resistors in a set of shunt resistances (hardware)
+- Add analog low-pass filter on receiver (hardware)
+- Battery recharge manager for monitoring (hardware)
+- Multi-channel acquisition (hardware)
+- Control OhmPi via microcontroller (hardware)
+
+Developing software features
+****************************
+If the new developments purely concern the software (e.g. bug fix, new acquisition strategy, etc.), then please follow the
+git best practices by first creating an new issue and then create a local branch linked to this issue. Once the new feature is implemented, a pull request can be initiated.
+
+Here is a series of software developments that are planned/hoped:
+- Sequence generator (software)
+- Calculate time-variable SP effects (software)
+- Calculate IP from full-waveform (software)
+- Pseudo multi-channel acquisition (software)
+
+Software interface to new hardware components
+*********************************************
+This section is intended for developers of a new hardware component as part of an OhmPi system.
+
+It presents some advices and best practices that should help developing new hardware components to work
+within an OhmPi system.
+
+Two cases should be distinguished when dealing with hardware development components:
+
+1- Developments of a hardware component that comply with the way the OhmPi Hardware System works. Such developments typically
+focus on improving an existing component (reduce cost, improve performance, adapt range to specific applications,
+design with easily available parts...). The newly created hardware component will expose the minimal functionalities required
+by hardware_system for this type of component.
+
+2- Developments of a hardware component that introduce changes in the way the OhmPi Hardware System works. Such
+developments do not only focus on improving a single component but also on the way to operate the system. A
+discussion with developers of the OhmPi_Hardware and OhmPi classes should be initiated at a very early stage to investigate
+the best ways to design and implement a working solution.
+
+If you are dealing with case 1 or have designed a development path and strategy, you are ready to start.
+
+First the hardware board/device should be conceived and designed. The Ohmpi team recommends that contributors design or
+import their boards within KiCAD and that both schemas and PCB are shared.
+
+When developing a new component Class, always start your development in a new branch.
+1- Create a new python file or make a copy and modify an existing similar component file. All hardware component modules
+are stored in the ohmpi/hardware_component directory.
+In the newly created python file, define a new class based on the relevant abstract class of abstract_hardware_components.py.
+Implement the abstract methods to interact with your hardware. Name the file according to the name of the component.
+Make sure to place this new python module in the ohmpi/hardware_component directory.
+
+2- Create a new configuration file or make a copy and modify an existing configuration file. All existing config files
+are stored in the ohmpi/hardware_component directory.
+In this newly created config file, describe your system including the new component in the HARDWARE_CONFIG dictionary.
+Name it config_XXX.py where XXX should be replaced by an expression describing the system.
+Make sure to place your new config file in the ohmpi/configs directory.
+
+3- Create a new script or make a copy and modify of an existing script for testing the component.
+In this script, write python code where you will conduct the tests of the required functionalities of the new component.

 Software architecture
-*********************
+#####################
 
 The OhmPi V2024 software has been completely re-structured to enable increased flexibility for both users and developers. The software is based on an object-oriented module with a class exposing the OhmPi
 functionalities used to interact with the OhmPi instrument via a web interface, IoT
 communication protocols (e.g. MQTT) and/or directly through the Python API.

      Software architecture of OhmPi V2024.
 
 The software is organised in several modules describing the system in a hierarchy including three levels of description and
 operation of the OhmPi.
 
-Hardware components
-===================
-On the base level, the five main hardware components are represented by distinct classes exposing the
-components atomic functionalities. Theses classes are abstract classes in order to provide a common
-interface for different implementations of a component. From these abstract classes concrete classes
-are implemented representing the default properties, actual capabilities and ways to interact with the
-physical modules or boards.
-Improving an existing hardware component or introducing a new design may be desirable in order to,
-e.g. reduce costs, improve performance, adapt measurement range to specific applications, or
-incorporate easily available electronic components. It is at this level that software developments are
-mainly expected to occur following updates on the hardware. The component class should expose the
-minimal functionalities required by the hardware system (see below) for this type of component.
+Acquisition
+***********
+On the top level, the OhmPi class (in ohmpi/ohmpi.py) includes all the higher-level methods and properties allowing to
+operate the system (e.g. acquire measurement sequences). The OhmPi class exposes the user-oriented
+API, generates logs and handles IoT messages. Generic users are expected to interact with the system
+through these higher-level functionalities, which are designed to remain as stable as possible while the
+hardware evolves. Only the introduction of new end-user functionalities should imply new
+developments at this level.
