Obsidian Internal Link
Official Documentation: help.obsidian.md
Used to link to another Obsidian Note in the same vault; one of the additional syntax options in Obsidian Flavored Markdown.
Syntax
There are two ways to make an Obsidian Internal Link: 1
- Using the Wikilink format:
                    
[[Three laws of motion]] - Using the Markdown format:
                    
[Three laws of motion](Three%20laws%20of%20motion.md) 
You can also link to a specific heading of a note
                    by using #. For example:
                    [[Three laws of motion#Second law]].
The display text of an Obsidian Internal Link can be changed in the following ways: 2
- Wikilink Format:
                    
[[Three laws of motion|Display Text]] - Markdown Format:
                    
[Display Text](Three%20laws%20of%20motion.md) 
When in a table, the pipe character
                    (|) used in the Wikilink format will
                    have to be escaped with a backslash
                    (\). 2
How to use
Always add display text for links. This gives a higher chance of allowing all of the links to be updated without accidentally changing the meaning or structure of the sentence containing the link. 3 4
