+# Mycelium
+
+Mycelium aims to provide an efficient compiled to intermediate bytecode implementation
+of R7RS Scheme as well as a virtual machine that will execute such bytecode.
+
+Two major use cases are at the forefront of mind when designing and implementing this
+project: a POSIX shell interpreter as well as a compiled to bytecode language for
+running on ESP32 devices.
+
+## Current Status
+Currently the lexer and parser are implemented. On an X86 machine equipped with 64GB
+RAM and an AMD Ryzen 7900 CPU this lexer and parser are capable of creating a fully
+validated abstract syntax tree from approximately 11200 lines of handwritten scheme
+in about 55 milliseconds on average.
+
+Currently the bytecode VM and its instruction set are next to implement.
