 # xighlight
 
-Xighlight C source code...
\ No newline at end of file
+xighlight -- Program for highlighting C source code in terminal.
+
+- Quickly written program to test out xtandard and xyntax, doesn't handle files, instead it records from standard input...
+- For now, 'xighlight' only works on ANSI C source code, without 'typedef' keyword, both will change in the future, and CLA will be added...
+- Everything related to my libraries is clean of all warning options on Clang, GCC and Valgrind.
+
+Compiling:
+
+```bash
+$ sh compile.sh
+```
+
+Installing:
+
+```bash
+$ sudo sh install.sh
+```
+
+Using:
+
+```bash
+$ cat my_c_program.c | xighlight
+$ xighlight < my_c_program.c
+```
+
+This is what it prints to standard output, when standard input is C source code:
+
+![alternative text]("c_hello.png");
