yq is written in go - so you can download a dependency free binary for your platform and you are good to go! If you prefer there are a variety of package managers that can be used as well as Docker and Podman, all listed below.
## Notice for v4.x versions prior to 4.18.1
Since 4.18.1, yq's 'eval/e' command is the _default_ command and no longer needs to be specified.
Older versions will still need to specify 'eval/e'.
Similarly, '-' is no longer required as a filename to read from STDIN (unless reading from one or more files).
TLDR:
Prior to 4.18.1
```bash
yq e '.cool' - < file.yaml
```
4.18+
```bash
yq '.cool' < file.yaml
```
When merging multiple files together, `eval-all/ea` is still required to tell `yq` to run the expression against all the document at once.
