+# UFB
+
+`/UFB/*.class` | `UFB.jar` is the interpreter | compiler merged as one.
+
+Only one file ending in `.ufbb` | `ufb` will be interpreted | compiled.
+
+A file will not be compiled | interpreted if there are errors.
+
+</div>

+
+## Usage
+
+```shell
+java -jar UFB.jar [ -flags ] [ file ]
+```
+
+---
+
+## Flags
+
+- "-p" -> Performance measurement flag -> ms
+- "-n" -> Accurately use the "-p" flag -> ns
+- "-m" -> Time all commands being run
+- "-v" -> Display semantic version tag
+- "-h" -> Display help links and sources
+- "-c" -> Compile file
+
+---
+
+## Example
+
+```shell
+java UFB -pnv
+java UFB -p
+java UFB -m
+java UFB -nvp
+java UFB -pnhv
+java UFB -mn
+java UFB -c ../test/UFB/Main.ufb
