+You can use this GitHub Action to commit changes made in your workflow run directly to your repo: for example, you use it to lint your code, update documentation, commit updated builds, etc....
 
 This is **heavily** inspired by [git-auto-commit-action](https://github.com/stefanzweifel/git-auto-commit-action) (by [Stefan Zweifel](https://github.com/stefanzweifel)): that action automatically detects changed files and commits them. While this is useful for most situations, this doesn't commit untracked files and can sometimes commit unintended changes (such as `package-lock.json` or similar, that may have happened during previous steps).  
-This action lets you choose the path that you want to use when adding & committing changes, so that it works as you would normally do using `git` on your machine.

 ### Environment variables:
 
 The only `env` variable required is the token for the action to run: GitHub generates one automatically, but you need to pass it through `env` to make it available to actions. You can find more about `GITHUB_TOKEN` [here](https://help.github.com/en/articles/virtual-environments-for-github-actions#github_token-secret).  
-With that said, you can just copy the example line and don't worry about it. If you do want to use a different token you can pass that in, but I wouldn't see any possible advantage in doing so.

 ### Adding files:
 
 The action adds files using a regular `git add` command, so you can put every kind of argument in the `add` option. For example, if you don't want it to use a recursive behavior: `$(find . -maxdepth 1 -name *.js)`.
-The script will not stop if one the git commands fails. E.g.: if your command shows a "fatal: pathspec 'yourFile' did not match any files" error the action will go on.

 ### Deleting files:
 
 You can delete files with the `remove` option: that runs a `git rm` command that will stage the files in the given path for removal.
