+## Code formatting by this extension doesn't seem to work.
+
+When you have multiple formatter extensions, be sure to set this
+extension as the default formatter for go language.
+```json5
+"[go]": {
+  "editor.defaultFormatter": "golang.go"
+}
+```
+
+## How can I stop the extension from formatting files on save?
+
+Formatting and organizing imports for Go are enabled by default. This is implemented
+by setting the [language-specific editor settings](https://code.visualstudio.com/docs/getstarted/settings#_languagespecific-editor-settings), that take precedence
+over user/workspace editor settings.
+
+You can choose to disable them by configuring the following settings.
+
+```json5
+"[go]": {
+        "editor.formatOnSave": false,
+        "editor.codeActionsOnSave": {
+            "source.organizeImports": false
+        }
+}
+```
+
+This decision was made a while ago to help users follow the best practice,
+and to detect broken code early (e.g. unused imports causes compile errors in Go).
+Unfortunately, these language-specific editor settings overriden by the
+extension is not easily visible from the settings UI, and confuses users new to Go.
+In the following issues, we are discussing and collecting ideas to improve
+the situation without interrupting existing users.
