- Install the ViolentMonkey Extension/Add-on
- Open this link (osu.place/get) to install the template manager script
- Open r/Place using this "special" Link to load the Touhou template automatically.
As an alternative, you can manually add
https://tp23.dogecore.net/template.jsonto your templates in the options menu, which will always load the template regardless of how you entered r/Place.
Use the Firefox (or Firefox Nightly) app and install the Tampermonkey add-on. Then open the script link.
Download the userscripts app, enable in safari -> manage extensions, click it to allow it on all sites. Then open the template manager userscript, open the extension and it should show "userscript detected, click here to install".
