+# miller.yazi
+
+[Miller](https://github.com/johnkerl/miller) now in [yazi](https://github.com/sxyazi/yazi). To install, clone the repo inside `~/.config/yazi/plugins/`:
+
+```toml
+[plugin]
+prepend_previewers = [
+    { mime = "text/csv", run = "miller"},
+]
+```
+
+## Preview
+
+![preview](https://github.com/Reledia/miller.yazi/blob/main/preview.png?raw=true)
+
+## Color
+
+To change colors of keys and values, edit the `init.lua` file after the `--key-color` and `--value-color` flags. To view a list of possible colors, use `mlr --list-color-names`. Make sure to have miller installed and inside your PATH.
+
+## Other types of file
+
+To adapt this plugin to the other format supported from miller (like json):
+- copy the plugin folder
+- change the name of the copied folder into miller_(fmt)
+- change the `--icsv` flag inside `init.lua` to `--i(fmt)`
+- add the correct mime/name rule into `prepend_previewers` and the exec as `miller_(fmt)`
