+# Well Plate Reader - Read well plates on Icy
+
+## Description
+
+This project contains the code necessary to import and show well plates from Opera machines.
+
+This project has been developed as a _Gradle_ project and can be opened with _Eclipse_ IDE.
+
+### Available plugins
+
+In danyfel.bigimage.io:
+
+- WellPlateImporter
+
+  This plugin reads the information of a well plate and then shows an interface with the available plates and their corresponding fields.
+
+
+## Installation
+
+### Requirements
+
+In order to be able to work with this project you must have installed the following software:
+
+- **Icy**, version 1.9.5.1 or above. ( [Available here](http://icy.bioimageanalysis.org) )
+  - The following plugins should be already installed in order to execute BigImageTools:
+    - EzPlug SDK
+    - Protocols SDK
+- **Eclipse**, version _Neon_ or above. Make sure to have the _Buildship_ plugin installed. ([Available here](http://www.eclipse.org/downloads/))
+- **Icy4Eclipse** plugin for Eclipse, the latest version available. Follow [these](http://icy.bioimageanalysis.org/index.php?display=startDevWithIcy) instructions.
+
+### Setup
+
+1. Use your *Git* repository manager of preference to download this repository (you can use Eclipse Git perspective to do this). The repository URL is [https://gitlab.pasteur.fr/bia/wellPlateReader.git](https://gitlab.pasteur.fr/bia/wellPlateReader.git).
+2. Make sure the environment variable **ICY_HOME** is set to the location of your Icy installation. _**Note**: This could be tricky on Mac so make sure to follow [these](https://stackoverflow.com/questions/829749/launch-mac-eclipse-with-environment-variables-set) instructions._
+3. Open Eclipse and select the menu *File > Import...* Then select *Gradle > Existing Gradle Project*. Click *Next* the project root directory is demanded select the folder **WellPlateReader** inside the folder you downloaded the at. Finally, click *Finish* to create the project in eclipse.
+
+Eclipse will download the dependencies specified in the *gradle.build* file. When it finishes you should see the project without any problem on the project explorer of Eclipse. *If this is not the case, check that the environment variable ICY_HOME is correctly defined.*
