+# The `fastbril` bytecode interpreter
+
+This is a bytecode spec/generator/interpreter for `bril`. It aims to
+be like the typescript or rust implementation, but faster.
+
+## To build
+
++ binary: `make release`
+  the binary will be `./build/fastbrili`
++ doc: you need to have LaTeX installed. run `make doc`
+  the doc will be `./doc/brb.pdf`
+  there is a prebuilt pdf in case this is difficult
+
+
+
+### Features
+We support a superset of the behavior provided by `brili`, so options like `-p`
+work exactly the same. We also support the following:
+ - `-b` will read in bytecode instead of the Bril json
+ - `-bo <file>` will output the bytecode to `<file>`
+ - `-pr` will print the program to standard out (probably more useful with the
+         `-b` option)
+ - `-ni` will NOT run the interpreter.
+ - `-e <file>` will emit assembly to `<file>`.
+
+the current only supported assembly is armv8. sorry.
+
+the compiler to asm is probably the least trustworthy part of this
+whole project. The general interpreter should be pretty good, but it
+is always possible there are bugs. Please report bugs to
+`[email protected]`, and there's a chance that i will fix them :)
