+# Web Dashboards Overview
+
+The default port is 19999; for example, to access the dashboard on localhost, use: http://localhost:19999
+
+To view netdata collected data you access its **[REST API v1](api/)**.
+
+For our convenience, netdata provides 2 more layers:
+
+1. The `dashboard.js` javascript library that allows us to design custom dashboards using plain HTML. For information on creating custom dashboards, see **[Custom Dashboards](gui/custom/)** and **[Atlassian Confluence Dashboards](gui/confluence/)**
+
+2. Ready to be used web dashboards that render all the charts a netdata server maintains.
+
+## customizing the standard dashboards
+
+Charts information is stored at /usr/share/netdata/web/[dashboard_info.js](gui/dashboard_info.js). This file includes information that is rendered on the dashboard, controls chart colors, section and subsection heading, titles, etc.
+
+If you change that file, your changes will be overwritten when netdata is updated. You can preserve your settings by creating a new such file (there is /usr/share/netdata/web/[dashboard_info_custom.example.js](gui/dashboard_info_custom_example.js) you can use to start with).
+
+You have to copy the example file under a new name, so that it will not be overwritten with netdata updates.
+
+To configure your info file set in netdata.conf:
+
+```
+[web]
+ custom dashboard_info.js = your_file_name.js
+```
