+Images, layout descriptions, binary blobs and string dictionaries can be included 
+in your application as resource files.  Various Android APIs are designed to 
+operate on the resource IDs instead of dealing with images, strings or binary blobs 
+directly.
+
+For example, a sample Android app that contains a user interface layout (main.axml),
+an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 
+would keep its resources in the "Resources" directory of the application:
+
+Resources/
+    drawable/
+        icon.png
+
+    layout/
+        main.axml
+
+    values/
+        strings.xml
+
+In order to get the build system to recognize Android resources, set the build action to
+"AndroidResource".  The native Android APIs do not operate directly with filenames, but 
+instead operate on resource IDs.  When you compile an Android application that uses resources, 
+the build system will package the resources for distribution and generate a class called "R" 
+(this is an Android convention) that contains the tokens for each one of the resources 
+included. For example, for the above Resources layout, this is what the R class would expose:
+
+public class R {
+    public class drawable {
+        public const int icon = 0x123;
+    }
+
+    public class layout {
+        public const int main = 0x456;
+    }
+
+    public class strings {
+        public const int first_string = 0xabc;
+        public const int second_string = 0xbcd;
+    }
+}
+
+You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main 
+to reference the layout/main.axml file, or R.strings.first_string to reference the first 
+string in the dictionary file values/strings.xml.

+# Simple Note
+
+This project is a structured note-taking software-server.
+
+# Client
+
+Client it self can also do note-taking locally without setup server.
+
+The client is written in C# using avalonia to achieve cross-platform.
+
+Target platforms:
+
+- Windows
+- Linux
+- macOS
+- Android
+- Web (WASM)
+
+# Server
+
+Server is also written in C# using ASP.Net Core Web API.
+
+Server is a distributed server structure. A server can set a destination server to sync content from and to target server. And server can broadcast data changes to other servers connected to it.
+
+The server utilizes RESTful API style: Only serve API services via HTTP requests.
+
+The server provides a multi-user service, every user has its own notebook. A user can share their notes/folders to anyone.
+
+For database, it can be configured as the server is a ASP.Net Core Web API application, and by default, it uses SQLite.
+
+# Underlying
+
+Each node (folder/note) have its own UUID and all its children are assigned via UUID, which allows symbollic linking a folder to another folder.
+
+Each node also have ACLs, controlls who can assess those nodes, (their owner always have full control).
+
+Permissions are:
+- View
+- Edit
+- Delete
+- Rename
+
+To setup a server network, every server should share a private-public certificate, if a server want to join (or connect to) another server, it must have the same private-public certificate.
