From Claudia Hauff's Paper Note Filler repo README
Installing the plugin manually
Note The plugin is not available via the Obsidian Hub as it takes quite a long time to get through the PR queue and the review process. This plugin is so niche and simple that it is not really worth it. So, manual installation it is.
-
Locate your vault folder and note down the path. You can find the folder name at the bottom left of your Obsidian window. If you click on the name, and thenÂ
Manage vaults
 you see the full path to the vault folder. -
Open the terminal andÂ
cd
 into theÂ.plugin
 directory inside your vault folder. For example, if your vault folder is inside your home directory and is calledÂmy-obsidian-notes
, you do: -
Create a new directory calledÂ
paper-note-filler
 inside theÂplugins
 directory andÂcd
 into it: -
DownloadÂ
main.js
,Âstyles.css
,Âmanifest.json
 from the latest release (not the cloned github repo!) to the just created directory.Check withÂ
ls -al
 if the three files are now appearing in theÂpaper-note-filler
 folder. Make sure they are not empty (more manifest.json
 should show a few lines of JSON).If the files are empty (GitHub downloads are not always straightforward withÂ
curl
), use the browser, head to the release page, download those three files via the browser and then move them into theÂpaper-note-filler
 directory. -
Restart Obsidian.
Ideally, this is it and the plugin is now installed. A simple way to check this is to now open the settings tab of Obsidian. Everything worked if the Paper Note Filling
 plugin listed under Community Plugins. If not, check the community-plugins.json
 file in the /plugins
 folder and add the plugin name manually if necessary and then restart Obsidian one more time.
