 ## API
 
+For run cli version use following code:
 ```typescript
-import {
-  JSCPD,
-  IClone,
-  IOptions,
-  MATCH_SOURCE_EVENT,
-  CLONE_FOUND_EVENT,
-  SOURCE_SKIPPED_EVENT,
-  END_EVENT
-} from 'jscpd';
-
-const options: IOptions = {};
-
-const cpd = new JSCPD(options);
-
-const code = '...string with my code...';
-
-cpd.on(MATCH_SOURCE_EVENT, (source) => {
-  // new source detection started
-  console.log(source);
-});
+import {IClone} from '@jscpd/core';
+import {jscpd} from 'jscpd';
 
-cpd.on(CLONE_FOUND_EVENT, (clone: IClone) => {
-  // clone found event
-  console.log(clone);
-});
-
-cpd.on(SOURCE_SKIPPED_EVENT, (stat) => {
-  // skipped source due size (see max-size, min-lines and max-lines options)
-  console.log(stat);
-});
-
-cpd.on(END_EVENT, (clones: IClone[]) => {
-  // detection process finished
-  console.log(clones);
-});
-
-cpd.detect(code, { id: 'test', format: 'markup' })
-  .then((clones: IClone[]) => console.log(clones));
-
-
-cpd.detectInFiles(['./src', './tests'])
-  .then((clones: IClone[]) => console.log(clones));
+const clones: Promise<IClone[]> = jscpd(process.argv);
 
+(async () => {
+    const clones: IClone[] = await jscpd(['', '', '/path/to/file/or/folder', '-m', 'weak', '--silent']);
+})();
 ```
 
+If you are going to detect clones in file system you can use [@jscpd/finder](../finder) for make a powerful detector.
+In case of detect clones in browser or not node.js environment you can build you own solution base on [@jscpd/code](../core)
