Porter offers two ways to install plugins. Users can install plugins one at a time or multiple plugins through a plugins definition file.

Below command will install one plugin:

porter plugins install NAME [flags]

To install multiple plugins at once, users can pass a file to the install command through --file flag:

porter plugins install --file plugins.yaml

The file format for the plugins.yaml can be found here: https://porter.sh/reference/file-formats/#plugins

By default plugins are downloaded from the official Porter plugin feed at https://cdn.porter.sh/plugins/atom.xml. To download from a mirror, set the environment variable PORTER_MIRROR, or mirror in the Porter config file, with the value to replace https://cdn.porter.sh with.`,
		Example: `  porter plugin install azure  
  porter plugin install azure --url https://cdn.porter.sh/plugins/azure
  porter plugin install azure --feed-url https://cdn.porter.sh/plugins/atom.xml
  porter plugin install azure --version v0.8.2-beta.1
  porter plugin install azure --version canary 
  porter plugin install --file plugins.yaml --feed-url https://cdn.porter.sh/plugins/atom.xml
  porter plugin install --file plugins.yaml --mirror https://cdn.porter.sh`,
