79.1	13	Once you have received your gateway and want to manage your gateway, you need to perform the following steps:
	14
	15
80.1	16	=== Step 1. Create an account ===
79.1	17
	18	Contact: support@dragino.cc
	19
	20	We will create a gateway management platform for you.Once created we will give you a platform and you will need to enter a password and then your gateway management platform will be created.
	21
	22
80.1	23	=== Step 2. Import Dashboard ===
79.1	24
	25	Before importing the dashboard we need to download the gateway management dashboard file from GitHub.
	26
	27	where to get:[[https:~~/~~/github.com/ThingsEye-io/te-platform/tree/main/Devices/Gateway/Gateway%20Management>>url:https://github.com/ThingsEye-io/te-platform/tree/main/Devices/Gateway/Gateway%20Management]]

	30
	31	Once the download is complete we need to import the dashboard into our gateway management account:
	32
	33	Firstly, we need to open the dashboard module,
	34
	35	click on the "+" in the upper right corner, select "import dashboard",
	36
	37	then we shoud drag the downloaded _dashboard file into the text box.

80.1	46	=== Step 3. Check the dashboard. ===
79.1	47
	48	Check if you can see your gateway information in the dashboard
