Use wikilink syntax with double brackets like [[Note Name]] to link between notes in your vault. Add a pipe for custom display text ([[Note|Text]]), a hash for headings ([[Note#Heading]]), or a caret for block references ([[Note#^block-id]]).

Write a blockquote starting with > [!type] where type is note, tip, warning, info, or another supported type. Add a custom title after the type, and use a minus sign (> [!faq]-) to make the callout collapsed by default or plus for expanded.

Wikilinks ([[Note]]) connect notes within your vault and are automatically updated by Obsidian when notes are renamed. Standard Markdown links ([text](url)) should be reserved for external URLs outside the vault.

Prefix a wikilink with an exclamation mark, such as ![[image.png]] or ![[document.pdf#page=3]]. You can control image size with a pipe parameter like ![[image.png|300]] for width or ![[image.png|640x480]] for exact dimensions.

Obsidian tags can contain letters in any language, numbers (not as the first character), underscores, hyphens, and forward slashes for nesting like #project/active. Tags can be written inline in the note body or listed under the tags property in YAML frontmatter.
