+# What it is
+
+This is simple logging library for Java, mostly written for myself. It can log what you want into file and console output.
+
+# Usage
+
+### Initialize
+
+There is 2 way to initialize the DLogger class. There is no particular difference between them.
+
+```
+DLogger logger = new DLogger(true);  
+// Log file name will be: 2024.03.06_14-37-12_log.log
+
+OR 
+
+DLogger logger = new DLogger(false, "log.log");  
+// Log file name will be: 2024.03.06_14-37-12_your_log_name.log
+// Chars \ / : * ? " < > | will be replace with _
+```
+
+### Using
+
+Now you can set up logging directory. But you don't have to, then the default directory will be the project root "./".
+
+```
+logger.setLogDir("/home/user/logs/");
+```
+
+Next you can use logger. Logger accepts 4 parameters:
+
+- String context - a property added for convenience that allows you to manually indicate where a log line was called from;
+- String text - log text;
+- boolean addTime - should logger add current time to log line
+- boolean addIndent - should logger add indent (22 spaces) to log line
+
+Example:
+
+```
+logger.log("Some context", "Some text", false false);
+// Output
+// [Some context] Some text
+
+
+logger.log("MyClass", "Abracadabra", true, false);
+// Output
+// [2024-03-06 15:28:31] [MyClass] Abracadabra
+
+
+logger.log("MyClass", "Abracadabra", false, true);
+// Output
+//                       [MyClass] Abracadabra
+
+
+logger.log("MyClass", "Abracadabra", true, true);
+// Output
+//                       [2024-03-06 15:28:31] [MyClass] Abracadabra
+
+
+// By the way you can use logger to log exeptions
+...
+catch(Exeption e){
+    for (StackTraceElement trace : e.getStackTrace()){
+        logger.log("MyClass Exeption", trace.toString(), true, false);
+    }
+}
+// Output
+// [2024-03-06 15:28:31] [MyClass Exeption] NullPointerExeption
+// [2024-03-06 15:28:31] [MyClass Exeption] Exeption trace line 1
+// [2024-03-06 15:28:31] [MyClass Exeption] Exeption trace line 2
+// ...
+```
