+### Autocorrection
+
+Rules that are marked as `[Correctable]` in the output can be automatically corrected using `--fix` flag:
+
+```sh
+$ ameba --fix
+```
+
+### Explain issues
+
+Ameba allows you to dig deeper into an issue, by showing you details about the issue
+and the reasoning by it being reported.
+
+To be convenient, you can just copy-paste the `PATH:line:column` string from the
+report and paste behind the `ameba` command to check it out.
+
+```sh
+$ ameba crystal/command/format.cr:26:83           # show explanation for the issue
+$ ameba --explain crystal/command/format.cr:26:83 # same thing
