Writing mermaid code is simple.

Creating diagrams and charts, using mermaid code is simple.

||||
But how is the code turned into a diagram in a web page? To do this we need a mermaid renderer.

The requirement is on the part of the web browser. Modern web browsers, such as Firefox, Chrome and Safari, can render mermaid. But Internet Explorer cannot. The web browser also needs access to the online mermaid renderer which it downloads from https://cdn.jsdelivr.net/npm/mermaid

Most widely used web browsers, such as Firefox, Chrome and Safari, can render mermaid, Internet Explorer however cannot. The web browser also needs access to the online mermaid renderer which it downloads from https://cdn.jsdelivr.net/npm/mermaid

|
||||
For an easy introduction, here follows three practical examples using:
|
||||
1. an online mermaid editor
|
||||
2. a mermaid plugin
|
||||
3. a generic web server of your choosing
|
||||
# For beginners, there are three relatively easy ways you can use mermaid:
|
||||
1. Using the mermaid [live editor](https://mermaid-js.github.io/mermaid-live-editor/)
|
||||
2. Using a mermaid plugin, such as that for Confluence or [Atom](https://atom.io/packages/atom-mermaid).
|
||||
3. Calling mermaid with HTML, deployed in a friendly browser.
|
||||
|
||||
Following either of these examples, you can get started with converting your own mermaid code into web diagrams.

## 1. The mermaid live editor
|
||||
|
||||
The quickest way to get started with mermaid is to visit [The mermaid live editor](https://mermaidjs.github.io/mermaid-live-editor).
|
||||
|
||||
In the `Code` section one can write or edit raw mermaid code, and instantly `Preview` the rendered result.

This is a great way to get started.

||||
It is also the easiest way to develop diagrams, the code of which can be pasted straight into documentation.
|
||||
It is also the easiest way to develop diagrams. You can also click "Copy Markdown" to copy the markdown code for the diagram, that can then be pasted directly into your documentation.
|
||||
You can also copy the code from the code section and paste it into either a mermaid plugin or in inside an html file, which will be taught in numbers 2 and 3.
|
||||
|
||||

|
||||

|
||||
|
||||
The `Mermaid configuration` is for controlling mermaid behaviour. An easy introduction to mermaid configuration is found in the [Advanced usage](n00b-advanced.md) section. A complete configuration reference cataloguing default values is found on the [mermaidAPI](mermaidAPI.md) page.

## mermaid using plugins
|
||||
## 2. Using mermaid plugins
|
||||
|
||||
Thanks to the growing popularity of mermaid, many plugins already exist which incorporate a mermaid renderer.
|
||||
One example is the [Atom plugin](https://atom.io/packages/atom-mermaid) for mermaid.
|
||||
|
||||
One example is the [Atlassian Confluence mermaid plugin](https://marketplace.atlassian.com/apps/1214124/mermaid-plugin-for-confluence?hosting=server&tab=overview)
|
||||
Another example is the [Atlassian Confluence mermaid plugin](https://marketplace.atlassian.com/apps/1214124/mermaid-plugin-for-confluence?hosting=server&tab=overview)
|
||||
|
||||
When the mermaid plugin is installed on a Confluence server, one can insert a mermaid object into any Confluence page.

We do not need to install anything on the server, apart from a program (like Notepad++) that can generate an html file, which is then deployed by a web browser (such as Firefox, Chrome, Safari, but not Internet Explorer).
|
||||
|
||||
So if you want to really simplify things when testing this out, don't use a web server at all but just create the file locally and drag it into your browser window. It is the browser which does all the work of rendering mermaid!

# Here are instructions for creating an html file with mermaid code:
|
||||
# Note that all this is written in the html `<body>` section of the web page.
|
||||
|
||||
When writing the html file, we give the web browser three instructions inside the html code:
|
||||
a. A reference for fetching the online mermaid renderer, which is written in Javascript.
|
||||
b. The mermaid code for the diagram we want to create.
|
||||
c. The `mermaid.initialize()` command to start the rendering process.
