+## Dprint
+
+Use dprint as below
+
+```console
+$ dprint --config dprint-ci.json check
+$ dprint --config dprint-ci.json fmt
+```
+
+Providing 2 config files. For the purpose below
+
+- [dprint-ci.json](dprint-ci.json) - Except ruby for faster run
+- [dprint.json](dprint.json) - Includes rubocop integration. Just using in vscode
+
+## Rubocop
+
+Using rubocop as a formatter. So recommend to execute it with servermode before editting code to reduce time.
+
+```console
+$ bundle exec rubocop --start-server
+```
+
+Vscode tasks does not include it because of executed server process will exists even after closing vscode.\
+Please manually kill it as below.
+
+```console
+$ bundle exec rubocop --stop-server
+```
+
+See [microsoft/vscode#65986](https://github.com/microsoft/vscode/issues/65986) for further detail.
