How can I get new Node in Library

Dear, I am new user in here and also a beginner of Dynamo.
Now, Im trying to run any script by referring anyone uploaded script in here. But, I have no enough Dynamo Nodes in Library. Anyone help me how to get Dynamo new nodes that I cant search in current situation, Have I need to download something.
If so, where I can do it?

From Package manager,

Tbh i have bad experience downloading packages using Dynamo.

I would suggest the manual option.

Downlaod packages from https://dynamopackages.com/.

Unzip the file and set the correct path in Dynamo.

Thank you for your answering.
