+## Running
+
+### Commandline Arguments
+
+- `-p INTERVAL` turns on the profiler and dumps info to the console every
+  `INTERVAL` seconds
+- `-s SIZE` sets the tile size for rendering; defaults to 512
+
+### Keyboard Shortcuts
+
+- `Ctrl-L` opens a dialog to browse to a new URL (Mac only currently)
+- `Ctrl--` zooms out
+- `Ctrl-=` zooms in
+- `Backspace` goes backwards in the history
+- `Shift-Backspace` goes forwards in the history
+
+## Developing
+
+There are lots of make targets you can use:
+
+- `make clean` - cleans Servo and its dependencies, but not Rust
+- `make clean-rust` - cleans Rust
+- `make clean-servo` - only cleans Servo itself (code in `src/components`
+- `make clean-DEP` - cleans the dependency `DEP`. e.g. `make clean-rust-opengles`
+- `make DEP` - builds only the specified dependency. e.g. `make rust-opengles`
+- `make check-DEP` - build and run tests for specified dependency
