{{% note "`.GitInfo` Performance Considerations" %}}
Hugo's Git integrations should be fairly performant but *can* increase your build time. This will depend on the size of your Git history.
{{% /note %}}
## `.GitInfo` Prerequisites
1. The Hugo site must be in a Git-enabled directory.
2. The Git executable must be installed and in your system `PATH`.
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].
## The `.GitInfo` Object
The `GitInfo` object contains the following fields:
.AbbreviatedHash
: the abbreviated commit hash (e.g., `866cbcc`)
.AuthorName
: the author's name, respecting `.mailmap`
.AuthorEmail
: the author's email address, respecting `.mailmap`
.AuthorDate
: the author date
.Hash
: the commit hash (e.g., `866cbccdab588b9908887ffd3b4f2667e94090c3`)
.Subject
: commit message subject (e.g., `tpl: Add custom index function`)
## `.Lastmod`
If the `.GitInfo` feature is enabled, `.Lastmod` (on `Page`) is fetched from Git i.e. `.GitInfo.AuthorDate`. This behaviour can be changed by adding your own [front matter configuration for dates](/getting-started/configuration/#configure-front-matter).
