Links

External links

Markdown style links can be used to refer to either external objects, such as web pages, or an internal page or image.

http://obsidian.md - automatic!
[Obsidian](http://obsidian.md)

http://obsidian.md - automatic! Obsidian

Obsidian URI links

[[Using obsidian URI|Obsidian URI]] links can be used to open notes in Obsidian either from another Obsidian vault or another program.

For example, you can link to a file in a vault like so (please note the [[Using obsidian URI#Encoding|required encoding]]):

[Link to note](obsidian://open?path=D:%2Fpath%2Fto%2Ffile.md)

Link to note

You can link to a note by its vault name and file name instead of path as well:

[Link to note](obsidian://open?vault=MainVault&file=MyNote.md)

Link to note

Reference Links

[You can use numbers for reference-style link definitions][1]

Or leave it empty and use the [link text itself][]

[1]: http://slashdot.org
[link text itself]: http://www.reddit.com

You can use numbers for reference-style link definitions

Or leave it empty and use the link text itself

Escaping

If there are spaces in the url, they can be escaped by either using %20 as a space, such as:

[Export options](Pasted%20image)

Export options

Or you can enclose the target in <>, such as:

[Slides Demo](<Slides Demo>)

Videos

• Copy the iframe of youtube and paste it

or...

They can't be added directly but you can add an image with a link to the video like this:

<a href="http://www.youtube.com/watch?feature=player_embedded&v=YOUTUBE_VIDEO_ID_HERE
" target="_blank"><img src="http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg" 
alt="IMAGE ALT TEXT HERE" width="240" height="180" border="10" /></a>

Or, in pure Markdown, but losing the image sizing and border:
[![IMAGE ALT TEXT HERE](http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg)](http://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE)

Inline code

Text inside `backticks` on a line will be formatted like code.

Code blocks

Syntax highlight is supported with the language specified after the first set of backticks. We use prismjs for syntax highlighting, a list of supported languages can be found at their site

```js
function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }
}
```

function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }
}

    Text indented with a tab is formatted like this, and will also look like a code block in preview.

Tables

You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe |:

First Header | Second Header
------------ | ------------
Content from cell 1 | Content from cell 2
Content in the first column | Content in the second column

First Header	Second Header
Content from cell 1	Content from cell 2
Content in the first column	Content in the second column

---

Tables can be justified with a colon | Another example with a long title
:----------------|-------------:
because of the `:` | these will be justified

If you put links in tables, they will work, but if you use Piped Links, the pipe must be escaped with a `\` to prevent it being read as a table element.

Footnotes

Here's a simple footnote,[^1] and here's a longer one.[^bignote]

[^1]: meaningful!

[^bignote]: Here's one with multiple paragraphs and code.

    Indent paragraphs to include them in the footnote.

    `{ my code }`

    Add as many paragraphs as you like.

Here's a simple footnote,¹ and here's a longer one.²

You can also use inline footnotes. ^[notice that the carat goes outside of the brackets on this one.]

Math

$$\begin{vmatrix}a & b\\
c & d
\end{vmatrix}=ad-bc$$

$$\begin{vmatrix}a & b\\ c & d \end{vmatrix}=ad-bc$$

You can also do inline math like $e^{2i\pi} = 1$ .

Obsidian uses Mathjax. You can check which packages are supported in Mathjax here.

Comments

Use %% to enclose comments, which will be parsed as Markdown, but will not show up in the preview.

Here is some inline comments: %%You can't see this text%% (Can't see it)

Here is a block comment:
%%
It can span
multiple lines

Diagram

Obsidian uses Mermaid to render diagrams and charts. Mermaid also provides a helpful live editor.

```mermaid
sequenceDiagram
    Alice->>+John: Hello John, how are you?
    Alice->>+John: John, can you hear me?
    John-->>-Alice: Hi Alice, I can hear you!
    John-->>-Alice: I feel great!
```

sequenceDiagram
    Alice->>+John: Hello John, how are you?
    Alice->>+John: John, can you hear me?
    John-->>-Alice: Hi Alice, I can hear you!
    John-->>-Alice: I feel great!

Loading

Obsidian supports linking to notes in Mermaid:

```mermaid
graph TD

Biology --> Chemistry

class Biology,Chemistry internal-link;
```

An easier way to do it is the following: ^376b9d

```mermaid
graph TD

A[Biology]
B[Chemistry]

A --> B

class A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z internal-link;
```

This way, all the note names (at least until Z[note name]) are all automatically assigned the class internal-link when you use this snippet.

If you use special characters in your note names, you need to put the note name in double quotes. "⨳ special character" It looks like this if you follow the [[Format your notes#^376b9d|second option]]: A["⨳ special character"]
