Style Guide

GitBook Markdown Syntax
Please refer to the GitBook Markdown Syntax guide.
Use of HBAR
When referring to the Hedera native currency, use the singular form of the noun HBAR. For example:
  • "I bought 10 HBAR yesterday"
Do not use the plural form of the noun, as this style rule applies even when referring to multiple units of HBAR.


When referring to fractions of HBAR, use the plural form tinybars. For example:
  • "I will transfer 1,000 tinybars from my account to yours"
Do not use the singular form of the noun, as any reference should be plural since one HBAR equals 100,000 tinybars.
Use of web2 and web3
When documenting or referring to "web2" and "web3," it's important to maintain consistency. Both terms should be in lowercase. The only exception to this rule is when either term starts a sentence. In such cases, the initial letter should be capitalized. For example:
  • Incorrect: "web3 technologies are evolving rapidly."
  • Correct: "Web3 represents a shift towards decentralization."
  • Correct: "In the context of web2, user data is often controlled by centralized entities."
  • Correct: "The principles of transparency and user empowerment are fundamental to the development of web3 platforms."
American English
Follow the American English spelling standard. This means that words should follow the American English conventions, employing 'z' instead of 's' in words such as 'decentralized,' 'realized,' and 'organized.'
For example:
  • Use 'color' instead of the British English 'colour.'
  • Use 'analyze' instead of the British English 'analyse.'
  • Use 'organization' instead of the British English 'organisation.'
Use an American English dictionary or a recognized American English style guide to ensure consistency and accuracy throughout the text. Tools like Grammarly or spell checkers set to American English can assist in maintaining this standard.
Tutorial steps
When presenting steps or instructions within the documentation, the following guidelines should be observed:
Ordered Steps (Numbered List): If the steps must be followed in a specific sequence, use a numbered list to present the order clearly. This ensures that readers understand the progression and importance of each step.
  1. 1.
    Clone repo.
  2. 2.
    cd into the cloned directory.
  3. 3.
    npm install
Unordered Steps (Bulleted List): If the order of the steps is not crucial to the outcome, use bulleted points. This provides flexibility for readers to approach the tasks as they prefer.
  • Choose a color.
  • Select a size.
  • Identify a preferred style.
Adhering to these guidelines will ensure readers' clarity and ease of understanding, allowing them to follow instructions effectively, whether in a precise sequence or with more flexible options.
Key Point: Use standard American capitalization. Use sentence case for headings.
Follow the standard capitalization rules for American English. Additionally, use the following style standards consistently throughout the Hedera developer documentation:
  • Follow the official capitalization of Hedera products, services, or terms defined by open-source communities, e.g., Hedera Consensus Service, Hedera Improvement Proposal, and Secure Hashing Algorithm.
  • Capitalize each instance of network names mainnet, testnet, and mirrornet only when preceded by Hedera, e.g., Hedera Mainnet, Hedera Testnet, and Hedera Mirrrornet.
  • Do not use all-uppercase or camel case except in the following contexts: in official names, abbreviations, or variable names in a code block, e.g., HBAR, HIPs, or SHA384.
  • You should revise any sentence starting with lowercase word stylization to avoid creating a sentence with a lowercase word.
Oxford comma
The Oxford comma is the comma used immediately before the coordinating conjunction ("and" or "or") in a list of three or more items. In our written content, the use of the Oxford comma is required to maintain clarity and prevent ambiguity.
Example: "The team consists of product managers, developers, designers, and writers."
By consistently applying the Oxford comma, we ensure that the meaning of lists is clear, especially when individual items contain commas themselves. This standard reflects our dedication to ensuring clear and accurate communication in all of our documentation.
Key Point: Use standard American and industry-standard abbreviations, e.g., NFT for non-fungible tokens. Avoid internet slang.
Abbreviations include acronyms, initialisms, shortened words, and contractions. In most contexts, the technical distinction between acronyms and initialisms isn't relevant; it's OK to use the phrase acronym to refer to both.
  • An acronym is formed from the first letters of words in a phrase/name but pronounced as if it were a word itself:
    • WAGMI for We're All Gonna Make It
    • DAO for Decentralized Autonomous Organization
  • An initialism is from the first letters of words in a phrase, but each letter is individually pronounced:
    • KYC for Know Your Customer
    • IPFS for InterPlanetary File System
  • A shortened word is just part of a word or phrase, sometimes with a period in the end:
    • Dr. for doctor
    • etc. for et cetera
Note: Some abbreviations can be acronyms or initialisms, depending on the speaker's preference—examples include FAQ and SQL. In some cases, the pronunciation determines whether to use a or an.

Long and short versions of a word

The short versions of the words are not abbreviations; if you use them, you don't need to put a period after them—for example:
  • application and app
  • synchronize and sync
If you're unsure whether a word is an abbreviation or a shortened version of a word, look in this list of resources. If that doesn't settle the issue, use the speaking test: if you speak the short version as a word (This is a demo version of the product), you can usually treat it as a word and not an abbreviation.

Don't create abbreviations

Use recognizable and industry-standard acronyms and initialisms. Abbreviations are intended to save the writer and the reader time. If the reader has to think twice about an abbreviation, it can slow down their reading comprehension.

Make abbreviations plural

Treat acronyms, initialisms, and other abbreviations as regular words when making them plural—for example, APIs, SDKs, and IDEs.

When to spell out a term

In general, when an abbreviation is likely to be unfamiliar to the audience, spell out the first mention of the term and immediately follow with the abbreviation in parentheses, for example:
  • Miner Extracted Value (MEV)
  • elliptic-curve cryptography (ECC)
For all subsequent mentions of the term, use the abbreviation by itself. If the first mention of a term occurs in a heading or title, you can use the abbreviation and then spell out the abbreviation in the first paragraph that follows the heading or section title.
In some cases, spelling out an acronym doesn't help the reader understand the term. For example, writing out a portable document format doesn't help the reader understand what a PDF document is.
Note: The following acronyms rarely need to be spelled out: API, SDK, HTML, REST, URL, USB, and file formats such as PDF or XML.
