 The plugin is not yet available in the Grafana Marketplace and must be installed manually. This requires enabling the Grafana option to install unsigned plugins. To do this, you have two options (you do not need to do both!):
 
 1. Put Grafana into 'development' mode by editing either the `grafana.ini` or `defaults.ini` file. Note: When installing [Grafana 10 from a tar file](https://grafana.com/grafana/download?pg=get&plcmt=selfmanaged-box1-cta1&platform=mac), there is no `grafana.in` and instead there is a `./conf/defaults.ini` file. Either way, edit the following line: `app_mode = development`

+2. Or, add the plugin to the whitelist by editing that same file and update this line: `allow_loading_unsigned_plugins = tinybird-tinybird-datasource`
