I wish to install a JSON editor in Eclipse, and I am trying to use Eclipse JSON Editor Plugin which is mentioned in an answer to this SO question.
I have copied the zip file from Sourceforge. How do I install the plugin and then how do I configure the editor in Eclipse to recognise and edit JSON files? I do not know how to install plugins manually so please assume ignorance and give detailed descriptions.
If there are better/newer solutions please indicate them.
I just went to the site and downloaded the file. You want the zip file that is downloaded. Once you have that, go to Help -> Install New Software. Click the Add.. Button and then the Archive button, and specify the location of the zip file you downloaded, and then proceed through the installation.

The zip file provided is set up for this type of installation within Eclipse.
