| description | MongoDB documentation style rules. Apply when writing or editing rST documentation. |
Hard Rules
- Line length: Break lines at 72 characters
- DO NOT change existing rST formatting or directives
- DO NOT add new information when editing existing docs
- Fix typos and grammatical errors only
rST Markup Formatting
Use the following markup styles when writing or editing documentation:
:guilabel: — UI Elements
Use for buttons, menus, dialogs, tabs, checkboxes, fields, icons, pages, windows.
Click :guilabel:`Save`.
In the :guilabel:`Database Name` field, enter a name.
Select :guilabel:`Start > Control Panel`.
:kbd: — Keyboard Shortcuts
Press :kbd:`Shift-G` and then press :kbd:`Enter`.
Monospace `text` — Code-Related Text
- Commands, flags, arguments:
`mongod`, `-t`
- Database/collection/file/directory names:
`mytestdb`, `/etc/`
- Environment variables:
`$PATH`
- Methods, elements, inline code:
`startTransaction()`
- Error messages, paths
Italics — Special Text
- Document titles: MongoDB Manual
- New terms on first use: swappiness
- Qualifiers: (Optional) Enter a name.
Bold — User Input
Titles and Headings
AP Headline-Style Capitalization
Capitalize all words except: articles (a, an, the), conjunctions (and, but, or),
prepositions, "to" in infinitives. Always capitalize first and last word.
Structure Rules
- Don't start with articles (a, an, the)
- Don't apply formatting in titles (no bold/italics/monospace)
- Don't stack headings — text must appear between them
- Limit to 2 heading levels when possible
- Place important words first (SEO)
Title Structure by Page Type
| Type | Structure | Example |
|---|
| Conceptual | Noun phrase | "How Monitoring Works" |
| Tutorial | Imperative verb | "Install MongoDB" |
| Reference | Plural noun | "Operators and Collectors" |
Code Examples
Use file-based directives, not hard-coded inline code:
.. literalinclude:: /path/to/file.js
:language: javascript
.. io-code-block::
.. input:: /path/to/input.py
.. output:: /path/to/output.txt
Terminology
| Avoid | Use |
|---|
| admin | administrator |
| argument (CLI) | option |
| blacklist/whitelist | access list |
| date (for timestamps) | timestamp |
| higher/lower (versions) | later/earlier |
| i.e. | that is |
| e.g. | for example |
| master/slave | primary/secondary |
| menu item, menu option | menu command |
| user (for people) | customer |
Client Library vs Driver
- client library: Use in TOC titles and headings
- driver: Use in body text (e.g., "MongoDB Java Driver")
- Don't use: "client drivers", "client connectors"
Prefer American English spelling.
