## Usage:
-Place the [bootstrap compiler](https://git.cshift.net/CircleShift/ctc) `ctc` in the folder and execute `run.sh`
+Place the [bootstrap compiler](https://git.cshift.net/CircleShift/ctc) `ctc` in this folder and execute `build.sh`
The compiler outputs x86 NASM compatible assembly.
Examples:
- `./ctc dummy.tnsl dummy.asm` - Run the bootstrap compiler on the dummy file, output to dummy.asm
-- `./run.sh` - Build the compiler
+- `./build.sh` - Build the compiler
