title: Monorepo
---
If you want to use GoReleaser within a monorepo and use tag prefixes to mark "which tags belong to which sub project", GoReleaser got you covered.
## Premise
You create your tags like `subproject1/v1.2.3` and `subproject2/v1.2.3`.
## Usage
You'll need to create a `.goreleaser.yml` for each subproject you want to use GoReleaser in:
```yaml
# subroj1/.goreleaser.yml
project_name: subproj1
monorepo:
tag_prefix: subproject1/
folder: subproj1
```
Then, you can release with (from the project's root directory):
```sh
goreleaser release --rm-dist -f ./subproj1/.goreleaser.yml
```
Then, the following is different from a "regular" run:
- GoReleaser will then look if current commit has a tag prefixed with `subproject1`, and also the previous tag with the same prefix;
- Changelog will include only commits that contain changes to files within the `subproj1` folder;
- Release name gets prefixed with `{{ .ProjectName }} ` if empty;
- All build's `dir` setting get set to `monorepo.folder` if empty;
- if yours is not, you might want to change that manually;
- Extra files on the release, archives, docker builds, etc are prefixed with `monorepo.folder`;
- On templates, `{{.PrefixedTag}}` will be `monorepo.prefix/tag` (aka the actual tag name), and `{{.Tag}}` has the prefix stripped;
The rest of the release process should work as usual.
