154 Use: "configure",
155 Short: "Configure a new bridge.",
156 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.
157 Repository configuration can be made by passing either the --url flag or the --project and --owner flags. If the three flags are provided git-bug will use --project and --owner flags.
158 Token configuration can be directly passed with the --token flag or in the terminal prompt. If you don't already have one you can use the interactive procedure to generate one.`,
159 Example: `# Interactive example
160[1]: github
161[2]: launchpad-preview
162target: 1
163name [default]: default

165Detected projects:

171Select option: 1
172
173[1]: user provided token
174[2]: interactive token creation
175Select option: 1
176
177You can generate a new token by visiting https://github.com/settings/tokens.
178Choose 'Generate new token' and set the necessary access scope for your repository.
179
180The access scope depend on the type of repository.
181Public:
182 - 'public_repo': to be able to read public repositories
183Private:
184 - 'repo' : to be able to read private repositories
