+![Default Severity Badge warn](https://img.shields.io/badge/Default%20Severity-warn-yellow)
+
+## Description
+Order the imports of the contract to follow a certain hierarchy (read "Notes section")
+
+## Options
+This rule accepts a string option of rule severity. Must be one of "error", "warn", "off". Default to warn.
+
+### Example Config
+```json
+{
+  "rules": {
+    "imports-order": "warn"
+  }
+}
+```
+
+### Notes
+- Paths starting with "@" like "@openzeppelin/" and urls ("http" and "https") will go first
+- Order by hierarchy of directories first, e.g. ./../../ comes before ./../, which comes before ./, which comes before ./foo
+- Order alphabetically for each path at the same level, e.g. ./contract/Zbar.sol comes before ./interface/Ifoo.sol
+- Rule does NOT support this kind of import "import * as Alias from "./filename.sol"
+- When "--fix",  rule will re-write this notation "../folder/file.sol" or this one "../file.sol" to "./../folder/file.sol" or this one "./../file.sol"
+
+## Examples
+This rule does not have examples.
+
+## Version
+This rule is introduced in the latest version.
+
+## Resources

+- [Document source](https://github.com/protofire/solhint/tree/master/docs/rules/naming/imports-order.md)
