2. on the right side **Download Package** option click it.
3. your package **.nupkg** file will be downloaded.
4. change its extension to .zip and extract it
5. go to lib and copy your package dll file from net or any netstandard folder. For [your unity project compatibility purposes][2] view this:
6. open unity workspace and create plugin folder
7. paste your dll file here.
