 ## Run Mojo Shell
 
-Devtools script `mojo_run` is a universal shell runner abstracting away the
-differences between running on Linux and Android. Having built Mojo as

 ```
 mojo/devtools/common/mojo_run mojo:spinning_cube  # Linux.

 ```
 
-Pass `--sky path_to_sky_file` to run a
-[Sky](https://github.com/domokit/mojo/tree/master/sky) app on either platform:
-```
-mojo/devtools/common/mojo_run --sky sky/examples/raw/hello_world.dart
-mojo/devtools/common/mojo_run --sky sky/examples/raw/hello_world.dart --android
-```
-
 Passing the `-v` flag will increase the output verbosity. In particular, it will
 also print all arguments passed by `mojo_run` to the shell binary.
 
-### Chromoting
-
-Some Mojo apps (Sky apps in particular) will need the --use-osmesa flag to run
-over [chromoting](https://support.google.com/chrome/answer/1649523?hl=en):
-
-```
-mojo/devtools/common/mojo_run --sky sky/examples/raw/hello_world.dart --use-osmesa
-```
