+| dry | :x: | `false` | Runs the action in dry mode. Files wont get changed and the action fails if there are unprettified files. Recommended to use with prettier_options --check |
-| prettier_version | :x: | False | Specific prettier version (by default use latest) |
+| prettier_version | :x: | `false` | Specific prettier version (by default use latest) |
-| prettier_options | :x: | `--write **/*.js` | Prettier options (by default it applies to the whole repository) |
+| working_directory | :x: | `false` | Specify a directory to cd into before installing prettier and running it, use relative file path to the repository root for example `app/` |
+| prettier_options | :x: | `"--write **/*.js"` | Prettier options (by default it applies to the whole repository) |
 | commit_options | :x: | - | Custom git commit options |

+| push_options | :x: | - | Custom git push options |
-| file_pattern | :x: | * | Custom git add file pattern |
+| same_commit | :x: | `false` | Update the current commit instead of creating a new one, created by [Joren Broekema](https://github.com/jorenbroekema), this command works only with the checkout action set to fetch depth '0' (see example 2)  |
-| branch (depreciated with 3.0)| :white_check_mark: | - | Always set this to `${{ github.head_ref }}` in order to work both with pull requests and push events |
+| commit_message | :x: | `"Prettified Code!"` | Custom git commit message, will be ignored if used with `same_commit` |
+| commit_description | :x: | - | Custom git extended commit message, will be ignored if used with `same_commit` |
+| file_pattern | :x: | `*` | Custom git add file pattern, can't be used with only_changed! |

+| only_changed | :x: | `false` | Only prettify changed files, can't be used with file_pattern! This command works only with the checkout action set to fetch depth '0' (see example 2)|
+| github_token | :x: | `${{ github.token }}` | The default [GITHUB_TOKEN](https://docs.github.com/en/actions/reference/authentication-in-a-workflow#about-the-github_token-secret) or a [Personal Access Token](https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token)
+
+> Note: using the same_commit option may lead to problems if other actions are relying on the commit being the same before and after the prettier action has ran. Keep this in mind.
