+*********************
+Contributing to no-OS
+*********************
+
+Fork and pull request workflow
+==============================
+
+When you don't have write permissions to the **no-OS** repository, the
+**fork and pull request** workflow can be used.
+
+More details: `GitHub Quickstart: Contributing to projects
+<https://docs.github.com/en/get-started/quickstart/contributing-to-projects>`_.
+
+Once a pull request is opened, select the **analogdevicesinc/noos** team as a
+reviewer. The changes should be approved by at least one no-OS maintainer
+before they can be merged to the base brach.
+
+Submission Checklist
+====================
+
+Before being reviewed by the no-OS maintainers and then accepted to the GitHub
+repository, each commit should respect a few rules:
+
+- The commit contains a **Signed-off-by** trailer by the committer at the end
+  of the commit log message - it certifies that the committer has the rights to
+  submit the work under the project's license.
+
+- If built using **gcc**, options such as **-Wall** and **-Wextra** don't
+  detect any issues with the commit. When the pull request is created, drivers
+  and project build are automatically triggered.
+
+- **astyle --style=linux --indent=force-tab=8 --max-code-length=80** doesn't
+  detect any issue with the commit.
+
+- A detailed description of how the new changes were tested is provided. This
+  information can be written in the pull request description. If the driver
+  was tested on one of the supported no-OS platforms, it is recommended to also
+  add a project example which uses the newly added driver.

+*******************
+no-OS drivers guide
+*******************
+
+This page represents a quick guide on how to create a no-OS driver and at the same time a generic documentation of the already available drivers.
+
+
+C code C++ compatible
+=====================
+
+The code must be written in C, but be compatible with C + + environments too since some platforms of this type (e.g., Mbed OS)  are already capable of using the no-OS drivers.
+
+Conversion from void*
+---------------------
+
+Implicit conversion from void* is forbidden in C + +, so, explicit cast is required.
+
+.. code-block:: C
+
+	struct ad1234_dev *dev;
+
+	dev = (struct ad1234_dev *)malloc(sizeof(*dev));
+
+Coding Style
+============
+
+While the preferred no-OS coding style is mainly the Linux kernel one (https://www.kernel.org/doc/html/latest/process/coding-style.html), we should still mention here some important rules.
+
+License Header
+--------------
+
+Each source or header file should include a license header - this will allow customers to quickly determine if the module can be used in their system.

+
+Include Guards
+--------------
+
+To prevent the inclusion of the header file content more than once, include guards must be used in all .h files.
+
+.. code-block:: C
+
+	#ifndef __AD1234_H__
+	#define __AD1234_H__
+
+	// ...
+
+	#endif // __AD1234_H__
+
+Indentation
+-----------
+
+Tabs should have a size of 8 characters and should be used instead of spaces for indentation (don't use 8 spaces instead of a tab).
+
+Naming
+------
+
+The name of the functions should be prefixed with the part number the driver is created for. If the driver will support multiple parts, the prefix can be the name of one of the parts.
+
+Variables
+---------
+
+In order to make the drivers support multiple instances, don't use global variables; use the device handler instead.
+
+Structures
+----------
+
+At least 2 structures need to be defined.
+
+1) Initialization structure
+...........................
+
+The initialization structure contains all the information required to initialize the device: the interface parameters (e.g., SPI, I2C, GPIOs) or device specific settings.
+
+.. code-block:: C
+
+	struct ad1234_init_param {
+		struct no_os_gpio_init_param gpio_reset;
+		struct no_os_spi_init_param  spi_init;
+		int                          some_settings;
+	};
+
+2) Device handler structure
+...........................
+
+The device handler structure contains all the information that must be passed between the driver's functions: the interface descriptors (e.g., SPI, I2C, GPIOs) or device specific settings.
+
+.. code-block:: C
+
+	struct ad1234_dev {
+		struct no_os_gpio_desc *gpio_reset;
+		struct no_os_spi_desc  *spi;
+		int                    some_settings;
+	};
+
+Functions
+---------
+
+Usually, all functions should return an integer error code (a negative number meaning an error).
+
+At least 2 functions need to be defined.
+
+1) Initialization function
+..........................
+
+It is mandatory to have this function; its name will be composed by a prefix (usually, the part number) and "_init" (e.g., ad1234_init()).
+
+It should take 2 arguments: a pointer to a pointer (it allocates memory for a structure that will be used outside) of a device handler structure and a pointer to an initialization structure.
+
+.. code-block:: C
+
+	int ad1234_init(struct ad1234_dev **device,
+			struct ad1234_init_param *init_param)
+
+
+It creates the device handler, initializes the communication peripherals, requests the GPIOs and set up the device according to the parameters specified in the dedicated structure.
+
+.. code-block:: C
+
+	{
+		struct ad1234_dev *dev;
+		int ret;
+
+		dev = (struct ad1234_dev *)malloc(sizeof(*dev));
+		if (!dev)
+			return -ENOMEM;
+
+		ret = no_os_gpio_get(&dev->gpio_reset, &init_param.gpio_reset);
+		if (ret)
+			goto error_1;
+
+		ret = no_os_spi_init(&dev->spi_desc, &init_param.spi_init);
+		if (ret)
+			goto error_2;
+		
+		dev->some_settings = init_param->some_settings;
+		ret =  ad1234_setup(dev);
+		if (ret)
+			goto error_3;
+
+		*device = dev;
+		
+		return 0;
+		
+		error_3:
+			spi_remove(dev->spi_desc);
+		error_2:
+			gpio_remove(dev->gpio_reset);
+		error_1:
+			free(dev);
+
+			return ret;
+	}
+
+2) Remove function
+..................
+
+It is mandatory to have this function; its name will be composed by a prefix (usually, the part number) and "_remove" (e.g., ad1234_remove()).
+
+.. code-block:: C
+
+	int ad1234_remove(struct adt1234_dev *dev)
+
+It frees the resources allocated by the initialization function.
+
+.. code-block:: C
+
+	{
+		int ret;
+		
+		ret = spi_remove(dev->spi_desc);
+		ret |= gpio_remove(dev->gpio_reset);
+
+		free(dev);
+
+		return ret;
+	}
+
+Please note that the remove() function cannot and does not set the provided pointer to NULL after deallocation of resources.
+
+Documenting the Code
+--------------------
+
+Doxygen comments of the code are required.
+
+Important Considerations
+========================
+
+Avoiding Race Conditions
+------------------------
+
+The no-OS software doesn't offer yet full support for Locks, Mutexes or Semaphores. If in the final application there is a risk of having multiple threads accessing the same resource at the same time, the user must deal with this threat so race conditions are avoided.
+
+Avoiding Heap Fragmentation
+---------------------------
+
+Since the driver's _init() function is allocating memory on heap and the _remove() one is clearing it, the user must pay attention to how many times and when these two are called in his or her final application so the heap fragmentation won't cause any harmful effect.
+
+Beautifying code
+================
+
+Once a new driver or an update is ready to be merged on the master branch, tools that check the coding style compliance can be used. Some examples are given below.
+
+Artistic Style
+--------------
+
+Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C++/CLI, Objective‑C, C# and Java programming languages.
+
+Example:
+
+.. code-block:: bash
+
+	analog@debian:~$ astyle --style=linux --indent=force-tab=8 --max-code-length=80 platform_drivers.c
+
+ClangFormat
+-----------
+
+Clang-Format is a tool to format C/C++/Java/JavaScript/Objective-C/Objective-C++/Protobuf code. It can be configured with a config file within the working folder or a parent folder.
+
+Example:
+
+Dump default configuration options to .clang-format.
+
+.. code-block:: bash
+
+	analog@debian:~$ clang-format -dump-config > .clang-format
+
+Modify .clang-format according to the project's specifications. Use -style=file command line option to use the customized style (.clang-format file).
+
+.. code-block:: bash
+
+	analog@debian:~$ clang-format -style=file -i platform_drivers.c
+
+Uncrustify
+----------
+
+Source Code Beautifier for C, C++, C#, ObjectiveC, D, Java, Pawn and VALA.
+
+Example:
+
+.. code-block:: bash
+
+	analog@debian:~$ wget https:/raw.githubusercontent.com/uncrustify/uncrustify/master/documentation/htdocs/default.cfg
+	analog@debian:~$ uncrustify -c default.cfg -f platform_drivers.c -o platform_drivers.c
