+# AppMan entries
 
+If you want to add your plugin, theme or extension to AppMan, you need to do a pull request to the appman.xml file adding a new entry inside the FD5 comments. Requirements for the offered plugins, themes or extensions are:
+
+* Code needs to be opensource and reviewable in a public repository
+* The item needs to be packaged into a FDZ file and provide a MD5 checksum for verification
+* The FDZ needs to extract the files to the user app data directory
+
+# Coding style
+
+##### Naming should be in English and clear
+
+```
+private int memberProperty = 0;
+```
+
+##### Use camelCase for private members and uppercase for public properties, methods and types:
+
+```
+private int memberProperty = 0;
+
+public string MemberName = "MemberName";
+
+public bool IsMember()
+{
+	return true;
+}
+```
+
+##### Use types without explicit path:
+
+```	
+private void OnFormActivate(object sender, /*System.*/EventArgs e)
+{
+	// Do something...
+}
+```
+
+##### Do not use extensive extra empty lines and keep the code clean, not like:
+
+```
+// Comment...	
+private int memberMethod(int value)
+{
+	
+	
+	
+	// Comment for something...
+	
+	
+	if (value > 2))
+	{
+		
+		//this.oldCode = 0;
+		
+		
+		// Random notes here
+		
+		
+		
+		return -1;
+	}
+	
+	
+	
+	// Something here too...
+	else return value;
+	
+	
+	
+	
+	//Little bit here too...
+}
+```
+
+##### Use brackets and parenthesis for easier readability:
+
+```
+if ((val1 > val2) && (val1 > val3))
+{
+    if (val2 > val3)
+	{
+		doThing();
+	}
+}
+```
+
+##### Do not nest expressions without brackets:
+
+```
+if (val1 > val2 && val1 > val3)
+
+	if (val2 > val3)
+	
+		doThing();
+
+```
+
+##### Use can use one liners to shorten the code:
+
+```
+if (val1 > val2 && val1 > val3)
+{
+	if (val2 > val3) doThing();
+}
+```
+
+##### Use explicit types:
+
+```
+Int myValue = 0;
+Point[] myPoints = new Point[]
+{
+	new Point(1, 1),
+	new Point(2, 2)
+}
+```
+
+##### Code example:
+
+```
+import System;
+
+namespace MyNameSpace
+{
+	class MyClass
+	{
+		// Comment here...
+		private int memberProperty = 0;
+		private int memberProperty2 = 1;
+		private int memberProperty3 = 2;
+		
+		// Comment here...
+		public string MemberName = "MemberName";
+		
+		// Comment here...
+		public static bool IsMemberProperty = false;
+		
+		// Comment here...
+		public const int CONSTANT = 1;
+		
+		/// <summary>
+		/// Comment here...
+		/// </summary> 
+		public bool IsMember()
+		{
+			return true;
+		}
+		
+		/// <summary>
+		/// Comment here...
+		/// </summary> 
+		public void MemberMethod(int value)
+		{
+			if (value > 2))
+			{
+				this.memberProperty2 = 2;
+				this.memberProperty3 = 3;
+			}
+			else this.memberProperty3 = value;
+		}
+		
+		/// <summary>
+		/// Comment here...
+		/// </summary> 
+		private int MemberMethodEx(int value)
+		{
+			this.memberProperty3 = 4;
+			switch (value)
+			{
+				case 1: return 1;
+				case 2:
+				{
+					return -1;
+				}
+				default: return value;
+			}
+		}
+		
+		/// <summary>
+		/// Comment here...
+		/// </summary> 
+		private void OnFormActivate(object sender, EventArgs e)
+		{
+			this.MemberMethod(null, null);
+		}
+
+	}
+	
+}
+```
+
+##### More generally, be consistent and keep the code clean!
