-## Dash (Multi-Host Dashboard)
-
-`dash-example.html` is an all-in-one page that automatically fetches graphs from all your hosts. Just add your graphs and charts (or use the defaults) one time using the `dash-*` syntax, and your selections will be automatically replicated for all of your hosts; showing alarms and graphs for all your hosts on **one page!**
-
-__**Dash will only work if you have implemented netdata streaming using `stream.conf`. It is not part of Netdata Cloud.**__
-
-`dash-example.html` was created as an experiment to demonstrate the capabilities of netdata in a multi-host environment. If you desire more features, submit a pull request or check out Netdata Cloud!
-
-### Configure Dash
-
-First, rename the file so it doesn't get overwritten. For instance, with a webroot at `/usr/share/netdata/web`:
-```bash
-cp /usr/share/netdata/web/dash-example.html /usr/share/netdata/web/dash.html
-```
-
-> NOTE: Ensure the owner/permissions match those in the rest of the files in the directory. Usually `netdata:netdata` and `0644`.
-
-Find and change the following lines in `dash.html` to reflect your Netdata URLs. The `REVERSE_PROXY_URL` is optional and only used if you access your Netdata dashboard through a reverse proxy. If it is not set, it defaults to the `NETDATA_HOST` URL.
-
-```js
-/**
- * Netdata URLS. If you use a reverse proxy, add it and uncomment the line below
- */
-NETDATA_HOST = 'https://localhost:19999';
-// REVERSE_PROXY_URL = 'https://my-domain.com/stats'
-```
-
-### The `dash-*` Syntax
-
-If you want to change the graphs or styling to fit your needs, just add an element to the page as shown. Child divs will be generated to create your graph/chart, and charts are replicated for each streamed host.
-```
-<div class="dash-graph"                     <----     Use class dash-graph for line graphs, etc
-    data-dash-netdata="system.cpu"          <----     REQUIRED: Use data-dash-netdata to set the data source
-    data-dygraph-valuerange="[0, 100]">     <----     OPTIONAL: This overrides the default config. Any other data-* attributes will
-</div>                                                          be added to the generated div, so you can set any desired options here
-
-<div class="dash-chart"                     <----     Use class dash-chart for pie charts, etc. CHARTS ARE SQUARE
-    data-dash-netdata="system.io"           <----     REQUIRED: Use data-dash-netdata to set the data source
-    data-dimensions="in"                    <----     Use this to override or append default options
-    data-title="Disk Read"                  <----     Use this to override or append default options
-    data-common-units="dash.io">            <----     Use this to override or append default options
-</div>
-```
-
-To change the sizes of graphs and charts, find the `DASH_OPTIONS` object in `dash.html` and set your preferences:
-```js
-/*
- * Change your graph/chart dimensions here. Host columns will automatically adjust.  
- * Charts are square! Their width is the same as their height.
- */
-DASH_OPTIONS = {
-    graph_width: '40em',
-    graph_height: '20em',
-    chart_width: '10em' // Charts are square
-}
-```
-
-To change the display order of your hosts, which is saved in localStorage, click the settings gear in the lower right corner
-
-We hope you like it!
