# Configuration
## Git config file
The most convenient way to configure delta is with a `[delta]` section in `~/.gitconfig`. Here's an example:
<sub>
```gitconfig
[core]
pager = delta
[interactive]
diffFilter = delta --color-only --features=interactive
[delta]
features = decorations
[delta "interactive"]
keep-plus-minus-markers = false
[delta "decorations"]
commit-decoration-style = blue ol
commit-style = raw
file-style = omit
hunk-header-decoration-style = blue box
hunk-header-file-style = red
hunk-header-line-number-style = "#067a00"
hunk-header-style = file line-number syntax
```
</sub>
Use `delta --help` to see all the available options.
Note that delta style argument values in ~/.gitconfig should be in double quotes, like `--minus-style="syntax #340001"`. For theme names and other values, do not use quotes as they will be passed on to delta, like `theme = Monokai Extended`.
All git commands that display diff output should now display syntax-highlighted output. For example:
- `git diff`
- `git show`
- `git log -p`
- `git stash show -p`
- `git reflog -p`
- `git add -p`
To change your delta options in a one-off git command, use `git -c`. For example
```sh
git -c delta.line-numbers=false show
```
There are several important environment variables that affect delta configuration and which can be used to configure delta dynamically.
Please see [Environment variables](./environment-variables.md).
In particular, note that delta does not currently honor all relevant [git environment variables](https://git-scm.com/docs/git-config#_environment), since delta uses [libgit2](https://github.com/libgit2/libgit2) to read git config.
