These guidelines are specific to and focused on GitHub product interfaces.

Your first port of call for general content guidelines should be GitHub’s content guide (link only accessible to GitHub staff), followed by the Microsoft Style Guide.

UI content principles

Keep the following principles in mind when creating UI content for GitHub.

1. Keep it clear

Aim for a seventh-grade or below reading level. This means you should write text that is straightforward, without trying to be creative with words.

There are some useful tools you can use to test your content for simplicity and reading level:

2. Keep it consistent

Refer to the same actions, sections, labels, landing pages, and so on, the same way across the product. But don’t sacrifice clarity over consistency.

Voice and tone

GitHub’s voice is:

  • Clear but not cold
  • Conversational but not jargon-y
  • Inclusive but not disingenuous
  • Helpful but not overly-prescriptive

Tone is how you express personality and mood depending on the situation. GitHub’s tone is almost always informal and positive, with adjustments when needed depending on the channel, audience, and emotional state of the audience.

You should consider the context of when a user will read something, keeping in mind that:

  • Humor isn’t welcome in all situations, for example: in errors, when waiting, or when something fails.
  • Error messages should be understandable by humans.

Top 10 rules

If you’re in a hurry, these are the most important content guidelines to keep in mind, in no particular order.

  • Write in plain English, don’t sound like a robot.
  • Be brief, remove unnecessary words like adjectives and adverbs.
  • Use active voice.
  • Use sentence case, and when in doubt, don’t capitalize.
  • Always capitalize GitHub correctly.
  • Avoid gendered language.
  • Do not use slang or culturally-specific references.
  • Do not use “here” or “click here” in calls to action.
  • Be very thoughtful when introducing humor to the interface.
  • Have someone else proofread your text.

Content guidelines

Acronyms and abbreviations

Use acronyms when they are more widely used than the spelled out term.

“Pull request” should never be abbreviated. It’s always lowercase unless it’s starting a sentence.

Dates and time

When referring to times, use am and pm, and not any other variation (a.m., A.M., AM).


Avoid using emojis, but when you do:

  • Use them only at the end of a sentence
  • Use only well-recognized emojis
  • Do not repeat emojis
  • Use emojis that will work well in both dark and light modes

Error messages

Be friendly and helpful, and avoid jargon. Do not blame the user.

Enter a name
Your name must be between 2 and 20 characters
Error 1234567890
You forgot to add your name

Be specific.

Enter a credit card number
Field required

In most cases, apologizing won't fix the problem. As a rule, do not apologize too much in any situation in the UI.

All checks failed
Sorry, all checks failed

Do not try to be funny or humorous.

Some checks failed
Oops, some checks failed


Feedback should be clear and reassuring, using the same terms used by the UI elements that triggered it. Don't try to be funny, and avoid jargon.

Issue transfer in progress

Feedback message when transferring an issue, using the same term ("transfer") as the trigger button
Moving the issue

Feedback message that uses a different term ("moving") than the trigger button


Use sentence case for form titles, labels, and fields. Do not include colons in form labels.

Labels and buttons

All labels and button text should be in sentence case, and not include punctuation.

When a sentence or label starts with a number (for example, “2 references”), the number is the first word, and the rest of the sentence should be in lowercase.

Action labels should start with an imperative verb that clearly indicates what to expect.

Save preferences

Action labels can be shortened to only include an adjective and a noun.

New issue

Use “sign in” rather than “log in”.

Link text should be meaningful and unique, with as few duplicated references as possible to prevent confusion. Ideally the link itself, or, alternatively, its programmatically determined context, should provide information about where the link will take you, and help users decide whether to follow the link. Examples of programmatically determined context can be aria labels, or text within the same paragraph as the link.

Headings, labels and buttons should not include punctuation. In most cases, exclamation marks are not appropriate — most things aren't that exciting.

References to UI

When referring to unclickable page names and sections, write them as they appear in the interface in quotation marks.

Go to the “Email notifications settings” section.

When referring to button or link text that a user should click on, use bold text without quotation marks. Make sure all UI references match the capitalization in the interface. If you’re writing for a mobile app experience, use “tap”, instead of “click”.

Click Save

When referring to a folder, use a code tag.


Open the docs folder.


In most instances, address the user as "you" and items "owned" by the user as "your" or "yours".

Some exceptions exist and are usually related to legal language, such as when a user needs to agree to terms, or confirm a destructive action.

What to avoid

  • Do not say that something is “easy”, “quick”, or that the user “just” needs to do something.
  • Do not capitalize common terms. Only proper nouns and product names should be capitalized.
  • Do not use emoji in UI content, or to replace words.
  • Use the word “and” instead of an ampersand or the “+” sign.
  • Do not use exclamation marks to indicate excitement, most actions aren’t.
  • Do not use the greater than and less than symbols to indicate steps in a flow.
  • Do not use semicolons: they are hard to get right and can be replaced by a period most times.

How to get help

If you need clarification and can’t find an answer in GitHub’s content guide (link only accessible to GitHub staff) or the Microsoft Style Guide, or would like your UI content to be reviewed, please start a discussion in github/primer and someone in the team will get back to you. If your query is urgent, you can ask directly in the #primer channel.
