+# EditorConfig
+
+This plugin implements the [EditorConfig](https://editorconfig.org/) spec
+purely on lua by leveraging lua patterns and the regex engine on lite-xl.
+Installing additional dependencies is not required.
+
+The EditorConfig spec was implemented as best understood,
+if you find any bugs please report them on this repository
+[issue tracker](https://github.com/lite-xl/lite-xl-plugins/issues).
+
+## Implemented Features
+
+Global options:
+
+* root - prevents upward searching of .editorconfig files
+
+Applied to documents indent info:
+
+* indent_style
+* indent_size
+* tab_width
+
+Applied on document save:
+
+* end_of_line - if set to `cr` it is ignored
+* trim_trailing_whitespace
+* insert_final_newline boolean
+
+## Not implemented
+
+* charset - this feature would need the encoding
+  [PR](https://github.com/lite-xl/lite-xl/pull/1161) or
+  [plugin](https://github.com/jgmdev/lite-xl-encoding)
+
+## Extras
+
+* Supports multiple project directories
+* Implements hot reloading, so modifying an .editorconfig file from within
+  the editor will re-apply all rules to currently opened files.
+
+## Testing
+
+This plugin includes a test suite to check how well the .editorconfig parser
+is working.
+
+The [editorconfig-core-test](https://github.com/editorconfig/editorconfig-core-test)
+glob, parser and properties cmake tests where ported and we are getting a 100%
+pass rate.
+
+If you are interested in running the test suite, from the terminal execute
+the following:
+
+```sh
+lite-xl test editorconfig
+```
+
+To inspect the generated sections and regex rules:
+
+```sh
+lite-xl test editorconfig --parsers
+```
