+# Holey-bytes VM playground
+
+This is my take on holey bytes toolchain, currently only an assembler written in C.
+
+## Building
+
+Run `make`, or `make CC=<your preferred C compiler> CFLAGS_EXTRA=<more flags>`
+
+## Usage
+
+To run the assembler, feed the input file to stdin, and the output will be in stdout.
+```
+./hbas --hex < input.S > output.hex
+./hbas < input.S > output.bin
+```
