-The following code illustrates what import this project aims to resolve.
+> import resolution and remapping.
 
+## Introduction
+
+jsenv use its own import resolution mostly because it uses some features not fully available in systemjs and rollup.<br />
+It uses `resolvePath` function exported here.
+
+## Installation
+
+```console
+npm install @jsenv/module-resolution
+```
+
+## `resolvePath`
+
+> takes { specifier, importer, importMap, defaultExtension } and returns a resolved path.
+
+##### basic example
+
 ```js
-// absolute
-import "https://domai.com:80/file.js"
-// protocol relative
-import "//file.js"
-// origin relative
-import "/root.js"
-// pathname relative beside
-import "./beside.js"
-// pathname relative below
-import "./folder/below.js"
-// pathname relative above
-import "../above.js"
-// bare
-import "fs"
+import { resolvePath } from "@jsenv/module-resolution"
+
+const resolvePath = resolveImport({
+  importer: "http://domain.com/folder/file.js",
+  specifier: "../index.js",
+})
+
+console.log(resolvePath)
 ```
 
-This project exports a `resolveImport` function capable to resolve these imports.
+The code above logs `http://domain.com/index.js`.
 
-## resolveImport
+##### remapping example
 
-Check [test](./test) folder to understand how this function works.
+```js
+import { resolvePath } from "@jsenv/module-resolution"
 
-## Bare import
+const resolvedPath = resolvePath({
+  importer: "http://domain.com/folder/file.js",
+  specifier: "../index.js",
+  importMap: {
+    imports: {
+      "/index.js": "/foo.js",
+    },
+  },
+})
 
-Here are some examples of bar imports: `import "fs"`, `import "lodash"`
-or `import "@babel/core"`.
+console.log(resolvedPath)
+```
 
-Inside a browser bare specifier will be [explicitely reserved](https://html.spec.whatwg.org/multipage/webappapis.html#resolve-a-module-specifier).
-This way third party module will not clash with future browser native modules.
+code above logs `http://domain.com/foo.js`.
 
-Inside node, [node module resolution algorithm](https://nodejs.org/api/modules.html#modules_all_together) find the corresponding file for you.
-It means node native module and third party module look the same.
+#### scoped remapping example
 
-# Installing
+```js
+import { resolvedPath } from "@jsenv/module-resolution"
 
-```console
-npm install --save-dev @jsenv/module-resolution
+const resolvedPath = resolvePath({
+  importer: "http://domain.com/folder/file.js",
+  specifier: "../index.js",
+  importMap: {
+    imports: {
+      "/index.js": "/foo.js",
+    },
+    scopes: {
+      "/folder/": {
+        "/index.js": "/bar.js",
+      },
+    },
+  },
+})
+
+console.log(remappedImport)
 ```
+
+code above logs `http://domain.com/bar.js`.
