excerpt: "A post to test author overrides using a data file."
---
Sites that may have content authored from various individuals can be accommodated by using [data files](https://jekyllrb.com/docs/datafiles/).
To attribute an author to a post or page that is different from the site author specified in `_config.yml`:
**Step 1.** Create `_data/authors.yml` and add authors using the following format. Anything variables found under `author` in `_config.yml` can be used (e.g. `name`, `avatar`, `uri`, social media profiles, etc.).
```yaml
# /_data/authors.yml
Billy Rick:
name: "Billy Rick"
uri: "http://thewhip.com"
email: "billy@rick.com"
bio: "What do you want, jewels? I am a very extravagant man."
