 # SteamQueryNet
-Steam Server Query API written in netstandard2.0
+
+SteamQueryNet is a C# wrapper for [Steam Server Queries](https://developer.valvesoftware.com/wiki/Server_queries) UDP protocol. It is;
+
+* Light
+* Dependency free
+* Written in .net standard 2.0 so that it works with both .NET framework 4.6+ and core.
+
+# How to install ?
+
+Check out [SteamQueryNet](https://www.nuget.org/packages/SteamQueryNet/) on nuget.
+
+# How to use ?
+
+SteamQueryNet comes with a single object that gives you access to all API's of the [Steam protocol](https://developer.valvesoftware.com/wiki/Server_queries) which are;
+
+* Server information (server name, capacity etc).
+* Concurrent players.
+* Server rules (friendlyfire, roundttime etc). **Warning: currently does not work due to a protocol issue on server source server.**
+
+## Creating an instance
+To make us of the API's listed above, an instance of `ServerQuery` should be created.
+
+```csharp
+string serverIp = "127.0.0.1";
+int serverPort = 27015;
+IServerQuery serverQuery = new ServerQuery(serverIp, serverPort);
+```
+
+once its created functions below returns informations desired,
+
+[ServerInfo](https://github.com/cyilcode/SteamQueryNet/blob/master/SteamQueryNet/SteamQueryNet/Models/ServerInfo.cs)
+```csharp
+ServerInfo serverInfo = serverQuery.GetServerInfo();
+```
+
+[Players](https://github.com/cyilcode/SteamQueryNet/blob/master/SteamQueryNet/SteamQueryNet/Models/Player.cs)
+```csharp
+// Concurrent Players
+List<Player> players = serverQuery.GetPlayers();
+```
+
+[Rules](https://github.com/cyilcode/SteamQueryNet/blob/master/SteamQueryNet/SteamQueryNet/Models/Rule.cs)
+```csharp
+// Rules
+List<Rules> rules = serverQuery.GetRules();
+```
+
+and thats it.
