This guide will help you get started and acquainted with Grafana. It assumes you have a working Grafana server up and running. If not please read the [installation guide]({{< relref "../installation/" >}}).
To run Grafana, open your browser and go to http://localhost:3000/. 3000 is the default HTTP port that Grafana listens to if you haven't [configured a different port]({{< relref "../installation/configuration/#http-port" >}}).
There you will see the login page. Default username is admin and default password is admin. When you log in for the first time you will be asked to change your password. We strongly encourage you to follow Grafana’s best practices and change the default administrator password. You can later go to user preferences and change your user name.
1. Move your cursor to the cog on the side menu which will show you the configuration menu. If the side menu is not visible click the Grafana icon in the upper left corner. Click on **Configuration** > **Data Sources** in the side menu and you'll be taken to the data sources page
where you can add add and edit data sources. You can also click the cog.
