+# hack-js
+
+hack-js is a JavaScript implementation of the computer architecture from
+the book "Elements of Computing Systems", which accompanies the [NAND to
+Tetris course](http://www.nand2tetris.org).
+
+hack-js uses a web browser to run .hack files containing machine code
+instructions. An HTML5 canvas is used to display operations that draw
+to the screen, and relevant keyboard events are forwarded to the Hack
+program.
+
+hack-js is a work in progress, and was inspired by the [London
+Computation Club](http://london.computation.club) meet-up.
+
+## Installing
+
+The only dependency is Node.js. No third-party libraries required.
+
+## Running
+
+Use the `bin/run` binary to run a given Hack file. For example:
+
+```
+$ bin/run Pong.asm
+Running Pong.asm at http://0.0.0.0:4225
+```
+
+This will launch a local web server on port 4225 ("HACK" on a phone
+keypad). Navigating to http://0.0.0.0:4225 in a reasonably recent
+browser will run the Hack program and display its output in a 256x512
+HTML5 canvas element.
