## Description

The `summary` file is an optional higher level form of repository metadata that describes the available branches. It needs to be manually regenerated after a series of commits. Among other things, this allows atomically updating multiple commits.

## Options

`--update`,`-u`

  Update the summary file. This option can be combined with `--add-metadata` to add metadata fields to the summary.

  If the repository has a collection ID configured, the `ostree-metadata` branch for that collection ID will also be updated with a new commit containing the given metadata, which will be signed if the summary file is signed.

`--add-metadata`,`-m`=KEY=VALUE

  Specify an additional metadata field to add to the summary. It must be in the format `KEY=VALUE` or as two separate arguments. The keys must be namespaced for your organisation or repository using a dot prefix. The values must be in GVariant text format. For example, `exampleos.end-of-life "@t 1445385600"`. This option can be used multiple times.

`--view`,`-v`

  View the contents of the summary file in a human readable format.

`--raw`

  View the raw bytes of the summary file.

`--gpg-sign`=KEYID

  GPG Key ID to sign the summary with.

`--gpg-homedir`=HOMEDIR

  GPG Homedir to use when looking for keyrings.

## Examples

`$ ostree summary -u`

`$ ostree summary -u -m key="'value'"`

`$ ostree summary -v`
