-# Documentation
+# Usage
 
 ## Create a graph (*DotGraph*)
 
 ```csharp
-var graph = new DotGraph("MyGraph");
+var graph = new DotGraph().WithIdentifier("MyGraph");
 
-var directedGraph = new DotGraph("MyDirectedGraph", true);
+var directedGraph = new DotGraph().WithIdentifier("MyDirectedGraph").Directed();
 ```
 
 ## Create and add a node (*DotNode*)
 
 ```csharp
-var myNode = new DotNode("MyNode")
-{
-    Shape = DotNodeShape.Ellipse,
-    Label = "My node!",
-    FillColor = Color.Coral,
-    FontColor = Color.Black,
-    Style = DotNodeStyle.Dotted,
-    Width = 0.5f,
-    Height = 0.5f,
-    PenWidth = 1.5f
-};
+var myNode = new DotNode()
+    .WithIdentifier("MyNode")
+    .WithShape(DotNodeShape.Ellipse)
+    .WithLabel("My node!")
+    .WithFillColor(Color.Coral)
+    .WithFontColor(Color.Black)
+    .WithStyle(DotNodeStyle.Dotted)
+    .WithWidth(0.5)
+    .WithHeight(0.5)
+    .WithPenWidth(1.5);
 
 // Add the node to the graph
-graph.Elements.Add(myNode);
+graph.Add(myNode);
 ```
 
 ## Create and add an edge (*DotEdge*)
 
 ```csharp
 // Create an edge with identifiers
-var myEdge = new DotEdge("myNode1", "myNode2");
-
-// Create an edge with nodes and attributes
-var myEdge = new DotEdge(myNode1, myNode2)
-{
-    ArrowHead = DotEdgeArrowType.Box,
-    ArrowTail = DotEdgeArrowType.Diamond,
-    Color = Color.Red,
-    FontColor = Color.Black,
-    Label = "My edge!",
-    Style = DotEdgeStyle.Dashed,
-    PenWidth = 1.5f
-};
+var myEdge = new DotEdge().From("Node1").To("Node2");
+
+// Or with nodes and attributes
+var myEdge = new DotEdge()
+    .From(node1)
+    .To(node2)
+    .WithArrowHead(DotEdgeArrowType.Box)
+    .WithArrowTail(DotEdgeArrowType.Diamond)
+    .WithColor(Color.Red)
+    .WithFontColor(Color.Black)
+    .WithLabel("My edge!")
+    .WithStyle(DotEdgeStyle.Dashed)
+    .WithPenWidth(1.5);
 
 // Add the edge to the graph
-graph.Elements.Add(myEdge);
+graph.Add(myEdge);
 ```
 
 ## Create a subgraph / cluster
 
 ```csharp
 // Subgraph identifier need to start with "cluster" to be identified as a cluster
-var mySubGraph = new DotSubGraph("cluster_0");
+var mySubGraph = new DotSubGraph().WithIdentifier("cluster_0");
 
 // Create a subgraph with attributes (only used for cluster)
-var mySubGraph = new DotSubGraph("cluster_0")
-{
-    Color = Color.Red,
-    Style = DotSubGraphStyle.Dashed,
-    Label = "My subgraph!"
-};
+var mySubGraph = new DotSubGraph()
+    .WithIdentifier("cluster_0")
+    .WithColor(Color.Red)
+    .WithStyle(DotSubGraphStyle.Dashed)
+    .WithLabel("My subgraph!");
 
 // Add node, edge, subgraph
-subGraph.Elements.Add(myNode);
-subGraph.Elements.Add(myEdge);
-subGraph.Elements.Add(mySubGraph2);
+subGraph.Add(myNode);
+subGraph.Add(myEdge);
+subGraph.Add(mySubGraph2);
 
 // Add subgraph to main graph
-graph.Elements.Add(mySubGraph);
+graph.Add(mySubGraph);
 ```
 
 ## Compile to DOT format
 
 ```csharp
-// Non indented version
-var dot = graph.Compile();
-// Indented version
-var dot = graph.Compile(true);
+await using var writer = new StringWriter();
+var context = new CompilationContext(writer, new CompilationOptions());
+await graph.CompileAsync(context);
+
+var result = writer.GetStringBuilder().ToString();
 
 // Save it to a file
-File.WriteAllText("myFile.dot", dot);
-```
+File.WriteAllText("graph.dot", result);
+```
