Obsidian Markdown Cheat Sheet

Properties

This is used to assign properties to your md document, and obsidian uses these to sort by tags etc.

Needs to be the first thing in your document.

---
tags: 
- documentation
- cheatsheet 
---

You can also add aliases and cssclasses, I don’t know what those are for:

---
tags:
  - documentation
  - cheatsheet
aliases:
cssclasses:

Inside of the Obsidian app, you can also add these in an other way:

1. Click the 3 dots inside your document.
2. Click + Add file property
3. Now it’s opened at the top of your document.

You can also generate UML with it:

	    CUSTOMER {
	        int id PK
	        string name
	        string email
	        string phone

	        int customer_id FK
	        float total_amount
	    }
	    ORDER_ITEM {

	    }
	    PRODUCT_SUPPLIER {
	        int product_id FK
	        int supplier_id FK
	    }
	
	     Relationships

Kanban Boards

pretty sure you need a plugin for this

	```kanban 
	# To Do 
	- Task 1 
	- Task 2  
	
	# In Progress 
	- Task 3 
	
	# Done 
	- Task 4 
	```

Table of Contents

pretty sure you need a plugin for this

[[toc]]

Templates

	```template
	Name:  
	Date: 
	```

These features are specific to Obsidian and may not be supported or have the same syntax in other Markdown editors. Make sure to check Obsidian’s documentation for any updates or additional features.

Search Queries

```query
tag:#documentation OR tag:#article OR tag:#tutorial 
```

tag:#documentation OR tag:#article OR tag:#tutorial

headers

When using Headers, only the following show up in your sidebar Table of Contents menu:

# Biggest header
## medium header
### smaller header

If you add more #‘s, they won’t be shown in the table of contents. And I think only the medium and smaller headers are clickable.

Tags

The example below is only for mentioning tags in your documents. It won’t make your document show up when filtering on the tags.

Tags

#tag
