107var bridgeConfigureCmd = &cobra.Command{
108	Use:   "configure",
109	Short: "Configure a new bridge.",
110	Long: `	Configure a new bridge by passing flags or/and using interactive terminal prompts. You can avoid all the terminal prompts by passing all the necessary flags to configure your bridge.
111	Repository configuration can be made by passing or the --url flag or the --project and/or --owner flags. If the three flags are provided git-bug will use --project and --owner flags.
112	Token configuration can be made by passing it in the --token flag or in the terminal prompt. If you don't already have one you can use terminal prompt to login and generate it directly.
113	For Github and Gitlab bridges, git-bug need a token to export and import issues, comments and editions for public and private repositories.
114	For Launchpad bridges, git-bug for now supports only public repositories and you only need --project or --url flag to configure it.`,
115	Example: `# For Github
116git bug bridge configure \
117    --name=default \
118    --target=github \
119    --owner=$(OWNER) \
120    --project=$(PROJECT) \
121    --token=$(TOKEN)
122
123# For Launchpad
124git bug bridge configure \
125    --name=default \
126    --target=launchpad-preview \
127    --url=https://bugs.launchpad.net/ubuntu/`,
