 # EODHistoricalData.NET
 
-C# Wrapper for EODHistoricalData REST API
+
+EODHistoricalData.NET is an easy-to-use .NET wrapper for EODHistoricalData REST API written in C#.
+
+## Getting Started
+EODHistoricalData.NET is a stand-alone .NET project.
+You can download the sources and add it as a project if you think you will need Debug possibilities.
+Or you can download the binary from the Release folder and add it as a file reference.
+
+## Usage
+
+### Instantiation
+Usage of a wrapper can't be more easy.
+You instantiate the EODHistoricalDataClient object, which is a Facade pattern, using your API token and you're good to go : 
+
+    EODHistoricalDataClient client = new EODHistoricalDataClient(Consts.ApiToken, true);
+
+The boolean parameter, which is optional, is the use of system-defined proxy.
+Specific full proxy configuration is not supported yet.
+
+### Api calls
+Then you just have to call the API you want, which returns the response in the corresponding structure.
+Here are a few examples : 
+
+    List<HistoricalPrice> prices = client.GetHistoricalPrices(Consts.TestSymbol, Consts.StartDate, Consts.EndDate);
+
+    List<RealTimePrice> prices = client.GetRealTimePrices(Consts.MultipleTestSymbol);
+
+Each method as its own set of parameters corresponding of the REST API parameters.
+
+For an exhaustive list of possible calls, you can check the units tests in the folder EODHistoricalData.NET.Tests folder.
