An open source note taking and to-do application with synchronisation capabilities

# Markdown Guide🔗

Markdown is a simple way to format text that looks great on any device. It doesn't do anything fancy like change the font size, color, or type — just the essentials, using keyboard symbols you already know. Since it is plain text, it is an easy way to author notes and documents and when needed it can be converted to a rich text HTML document.

Joplin desktop and mobile applications can display both the Markdown text and the rendered rich text document.

## Cheat Sheet🔗

This is a quick summary of the Markdown syntax.

Tables See below

### Tables🔗

Tables are created using pipes | and and hyphens -. This is a Markdown table:

| First Header  | Second Header |
| ------------- | ------------- |
| Content Cell  | Content Cell  |
| Content Cell  | Content Cell  |


Which is rendered as:

Content Cell Content Cell
Content Cell Content Cell

Note that there must be at least 3 dashes separating each header cell.

Colons can be used to align columns:

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 | | col 2 is | centered |$12 |


Which is rendered as:

Tables Are Cool
col 3 is right-aligned $1600 col 2 is centered$12

## Joplin Extras🔗

Besides the standard Markdown syntax, Joplin supports several additional features.

You can create a link to a note by specifying its ID in the URL. For example:

[Link to my note](:/0b0d62d15e60409dac34f354b6e9e839)


Since getting the ID of a note is not straightforward, each app provides a way to create such link. In the desktop app, right click on a note an select "Copy Markdown link". In the mobile app, open a note and, in the top right menu, select "Copy Markdown link". You can then paste this link anywhere in another note.

### Math notation🔗

Math expressions can be added using the KaTeX notation. To add an inline equation, wrap the expression in $EXPRESSION$, eg. $\sqrt{3x-1}+(1+x)^2$. To create an expression block, wrap it as follow:

$$EXPRESSION$$


For example:

$$f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi$$


Here is an example with the Markdown and rendered result side by side:

### Chemical equations🔗

Joplin supports chemical equations via the mhchem plugin for KaTeX. This plugin is automatically enabled if you enable math notation. See the mhchem documentation for the syntax.

### Diagrams🔗

You can create diagrams in Joplin using the Mermaid syntax. To add such a graph, wrap the Mermaid script inside a "mermaid" code block like this:

mermaid
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;



This is how it would look with the Markdown on the left, and rendered graph on the right:

Note that Mermaid graphs are always rendered on a white background regardless of the current theme. This is because they can contain various colours that may not be compatible with the current theme.

### Checkboxes🔗

Checkboxes can be added like so:

- [ ] Milk
- [x] Rice
- [ ] Eggs


Which would turn into:

The checkboxes can then be ticked in the mobile and desktop applications.

### HTML support🔗

It is generally recommended to enter the notes as Markdown as it makes the notes easier to edit. However for cases where certain features aren't supported (such as strikethrough or to highlight text), you can also use HTML code directly. For example this would be a valid note:

This is <s>strikethrough text</s> mixed with regular **Markdown**.


### Plugins🔗

Joplin supports a number of plugins that can be toggled on/off to enable/disable markdown features on top of the standard Markdown features you would expect. These plugins are listed below. Note: not all of the plugins are enabled by default, if the enable field is 'no' below, then open the option screen to enable the plugin. Plugins can be disabled in the same manner.

Note that the functionality added by these plugins is not part of the CommonMark spec so, while they will all work within Joplin, it is not guaranteed that they will work in other Markdown readers. Often this is not an issue but keep it in mind if you require compatibility with other Markdown applications.
