+# Contributing
+
+Contributions are **welcome** and will be fully **credited**.
+
+Please read and understand the contribution guide before creating an issue or pull request.
+
+## Etiquette
+
+This project is open source, and as such, the maintainers give their free time to build and maintain the source code
+held within. They make the code freely available in the hope that it will be of use to other developers. It would be
+extremely unfair for them to suffer abuse or anger for their hard work.
+
+Please be considerate towards maintainers when raising issues or presenting pull requests. Let's show the
+world that developers are civilized and selfless people.
+
+It's the duty of the maintainer to ensure that all submissions to the project are of sufficient
+quality to benefit the project. Many developers have different skillsets, strengths, and weaknesses. Respect the maintainer's decision, and do not be upset or abusive if your submission is not used.
+
+## Viability
+
+When requesting or submitting new features, first consider whether it might be useful to others. Open
+source projects are used by many developers, who may have entirely different needs to your own. Think about
+whether or not your feature is likely to be used by other users of the project.
+
+## Procedure
+
+Before filing an issue:
+
+- Attempt to replicate the problem, to ensure that it wasn't a coincidental incident.
+- Check to make sure your feature suggestion isn't already present within the project.
+- Check the pull requests tab to ensure that the bug doesn't have a fix in progress.
+- Check the pull requests tab to ensure that the feature isn't already in progress.
+
+Before submitting a pull request:
+
+- Check the codebase to ensure that your feature doesn't already exist.
+- Check the pull requests to ensure that another person hasn't already submitted the feature or fix.
+
+## Requirements
+
+If the project maintainer has any additional requirements, you will find them listed here.
+
+- **Document any change in behaviour** - Make sure the `README.md` and any other relevant documentation are kept up-to-date.
+
+- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+
+- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please [squash them](https://www.git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Changing-Multiple-Commit-Messages) before submitting.
+
+**Happy coding**!

 Before using this library, please read the "[Google Maps Android API utility library documentation](https://developers.google.com/maps/documentation/android-sdk/utility/)" .
 
+You can see the demo for more details.
+
+NOTE:
+  -Before Building the demo, you must [get an API key](https://developers.google.com/maps/documentation/android-sdk/signup) which you can then add to your demo app.
+
 ### Marker
 
 Firstly, you need to generate markers that have a name.
 You must initialize `CMaker` class that is implemented `ClusterItem` and pass the LarLng, the name of marker and the drawable Id. Also you can set the title and snippet of marker.
 
 ```java
 
-CMarker marker = new CMarker(new LatLng(), "Somthing", 12355468);
-marker.setTitle("somthing");
+CMarker marker = new CMarker(new LatLng(52.22222, 36.25622), "Ford", 12355468); //(Location of marker, specifed name, the drawable marker ID)
+marker.setTitle("somthing you want to display when you tap on marker");
+
+
+CMarker marker2 = new CMarker(new LatLng(52.25552, 36.25624), "Toyota", 12355469); //(Location of marker, specifed name, the drawable marker ID)
+marker.setTitle("somthing you want to display when you tap on marker");
+ 
+//...
+```
+Add the marker to the `addItem()` method;
 
+```java
+clusterManager.addItem(marker);
+clusterManager.addItem(marker2);
+//...
 ```
+
 ### Chart
 
 This library uses the the name to calculate the values of charts. In face, the number of  each slice of chart is sum of names.
