    22  {{% note "`.GitInfo` Performance Considerations"  %}}
    23  Hugo's Git integrations should be fairly performant but *can* increase your build time. This will depend on the size of your Git history.
    24  {{% /note %}}
    25  
    26  ## `.GitInfo` Prerequisites
    27  
    28  1. The Hugo site must be in a Git-enabled directory.
    29  2. The Git executable must be installed and in your system `PATH`.
    30  3. The `.GitInfo` feature must be enabled in your Hugo project by passing `--enableGitInfo` flag on the command line or by setting `enableGitInfo` to `true` in your [site's configuration file][configuration].
    31  
    32  ## The `.GitInfo` Object
    33  
    34  The `GitInfo` object contains the following fields:
    35  
    36  .AbbreviatedHash
    37  : the abbreviated commit hash (e.g., `866cbcc`)
    38  
    39  .AuthorName
    40  : the author's name, respecting `.mailmap`
    41  
    42  .AuthorEmail
    43  : the author's email address, respecting `.mailmap`
    44  
    45  .AuthorDate
    46  : the author date
    47  
    48  .Hash
    49  : the commit hash (e.g., `866cbccdab588b9908887ffd3b4f2667e94090c3`)
    50  
    51  .Subject
    52  : commit message subject (e.g., `tpl: Add custom index function`)
    53  
    54  ## `.Lastmod`
    55  
    56  If the `.GitInfo` feature is enabled, **and** if the `lastmod` field in the content's front matter is not set, `.Lastmod` (on `Page`) is fetched from Git i.e. `.GitInfo.AuthorDate`.
