The main thing you can contribute with on the Arduino Documentation repository, is the fixing of bugs, misspelling and other similar but small issues.

You are allowed to suggest these changes on all content available in this repository.

You are also allowed to add your own content to the Arduino Documentation repository. You are more than welcome to contribute with the following:

*Note that the contributed Projects should be added to Project Hub instead of on the Arduino Documentation website.

For us to be able to approve your contribution, you should follow the guidelines on how to structure and write your content.

Please read the Arduino Style Guide.

To write a tutorial for the Arduino Documentation website, you should follow these guidelines:

Section	Rules	Description	Example
Frontmatter	You must fill in title, description and author. The others are voluntary.	Here is where you add the metadata of your tutorial. This is including the author, title of tutorial, compatible libraries, compatible hardware etc.
Introduction	This is an h2 heading. You should not change the name of the heading.	The Introduction to the tutorial should be a maximum of three sentences long and be well descriptive of what the reader can expect of the tutorial.
Goals	This is an h2 heading. You should not change the name of the heading.	What are the goals of this tutorial? What should the reader be able to do at the end?
Hardware & Software Needed	This is an h2 heading. You should not change the name of the heading.	Here you set the hardware and software you need to continue your tutorial. You are more than welcome to link the Arduino based software and hardware to the respective store or downloads page.
Circuit/Schematic	This is an h2 heading. You should not change the name of the heading.	Here you add the circuits and/or schematics of your tutorial.
Focus Feature	This is an h2 heading. Here you are allowed to use as many h3 headings as you want, to be able to divide your content into easier to read sections. You can add up to three Focus Feature headings in your tutorial. This is the only heading you are allowed to modify.	This sections heading should be updated to the main focus of your tutorial. This is where the information about the focus start.
Programming the Board	This is an h2 heading. You should not change the name of the heading.	This is the section where you go through the code of your tutorial.
Testing it Out	This is an h2 heading. You should not change the name of the heading.	This is the experimental part of your tutorial, where the reader is supposed to test out the code and focus of your tutorial.
Troubleshoot	This is an h3 heading. You should not change the name of the heading.	If there are something in your tutorial that you know people might get stuck on, or get wrong, this is the section where you give suggestion on how the reader can troubleshoot.
Conclusion	This is an h2 heading. You should not change the name of the heading.	This is where you summarize your tutorial in a few sentences. What is it that you hoped to have taught or shown the reader?

To write a How To for the Arduino Documentation website, you should follow these guidelines:

Section	Rules	Description	Example
Frontmatter	You must fill in title, description and author. The others are voluntary.	Here is where you add the metadata of your How To. This is including the author, title of How To, compatible libraries, compatible hardware etc. You must fill in title, description and author. The others are voluntary. Note that you must remove the sections in the frontmatter which are empty.
Introduction	This is an h2 heading. You should not change the name of the heading.	The Introduction to the tutorial should be a maximum of three sentences long and be well descriptive of what the reader can expect of the How To.
Hardware & Software Needed	This is an h2 heading. You should not change the name of the heading.	Here you set the hardware and software you need to continue your How To. You are more than welcome to link the Arduino based software and hardware to the respective store or downloads page.
Circuit	This is an h2 heading. You should not change the name of the heading.	Here you add the circuit/s and of your How To.
Schematic	This is an h2 heading. You should not change the name of the heading.	Here you add the schematic/s and of your How To.
Code	This is an h2 heading. You should not change the name of the heading.	This is where you add your sketch code as well as the descriptive text explaining what the code does and is used for.
Learn more	This is an h2 heading. You should not change the name of the heading.	This is where you link to more information that the reader could be interested in. This could for example be other tutorials that delve deeper into the same topic, or a project that focus on the learnings of this How To.

To write a article for the Arduino Documentation website, you should follow these guidelines:

Section	Rules	Description	Example
Frontmatter	You must fill in title, description and author. The others are voluntary.	Here is where you add the metadata of your article. This is including the author, title of tutorial, compatible libraries, compatible hardware etc.

Circuit/Schematic	This is an h2 heading. You should not change the name of the heading.	Here you add the circuits and/or schematics of your tutorial.

We write all of our content in markdown. To be able to contribute properly to our website, we suggest you to do the same. Practice your markdown skills here: https://commonmark.org/help/tutorial/

You should use the following markdown styling for our content:

Style	Use	Description	Example
Bold	**bold**	Use bold when you are referring to either a path in the chosen software, or when you want to highlight a specific topic or button.
Inline Code	`code`	Use the inline code markdown for code inside text sections.
Code Snippet	```arduino this is my code ```	Use the code snippet markdown for longer code snippets.
Notes	***Note: This is my note.***	Use the three asterisks for note tags. Note that these can’t contain line-breaks unless made with a <br> tag.
Quotes	> This is a quote.	Use sparsely and with quotes only.
Bullet points	* bullet point 1 * bullet point 2 * bullet point 3	Use the * or the - to make bullet points in your tutorial. If your bullet point is a full sentence, remember to punctuate it. If your bullet point is a single word, or words not making a sentence, leave the punctuation off.
Numbered lists	**1.** One **2.** Two **3.** Three	Make sure to bold your numbering lists to make them format properly.
Paths	This > is > my > path	Use > when describing paths in your chosen software.
Images		Use the image tag to display images.

Note that we are not including cursive writing as a markdown style. We implore you not to use cursive as a means to highlight text. Instead use bold.

If you want to include unit symbols or trademarked names in your content, please follow these guidelines.

For all unit symbols, make sure to include a space between the number and the symbol.

Wrong: 1.75μm pixel size

Note that this table will be updated with more examples in the future.

Note that this table will be updated with more examples in the future.

These are some other naming structures that we recommend using:

• OpenMV
• MicroPython
• OTA (Over-the-air)
• USB-_ (A/B/C)

Note that this list will be updated with more examples in the future.

All graphics should be 1920x1080. All graphics are stored in an assets folder in the tutorial/article/how-to folder. See section Naming Guidelines.

Type	Purpose	Example
Circuit/Schematic	Circuit diagrams represent how Arduino products work with components in order to function. A schematic is a stylized electronic diagram explaining electric circuits.
Screenshot	Screenshots are most often used to show the program in the Arduino IDE or any other chosen software.

Name the folder after the title of your documentation. The name of the folder should contain a maximum of 4 words divided by dashes.

connector-basics

SoftwareSerialExample

The folder should then contain an assets folder, as well as the main content markdown file. It’s important to name the main content file the same name as the folder.

connector-basics.md

SoftwareSerialExample.md

There is no specific way you need to name the images, however it is a good practice to add something descriptive in the name. Also remember to divide words by using dashes.
