+If you want to work remotely from your laptop with an Android device attached to
 it, while keeping an ssh connection to a remote desktop machine where you have
 your build environment setup, you will have to use one of the two alternatives
 listed below.
 
 ## Option 1: SSHFS - Mounting the out/Debug directory
 
 ### On your remote host machine
 
 You can open a regular ssh to your host.
 
     # build it
     desktop$ cd $SRC;
     desktop$ . build/android/envsetup.sh
     desktop$ build/gyp_chromium -DOS=android
     desktop$ ninja -C out/Debug

 laptop$ sudo apt-get install sshfs
 
 # Mount the chrome source from your remote host machine into your local laptop.

 laptop$ sshfs your.host.machine:/usr/local/code/chrome/src ./chrome_sshfs

 laptop$ python build/android/adb_install_apk.py --apk ContentShell.apk --apk_package org.chromium.content_shell
 
 # Run tests.
 
 laptop$ python build/android/run_instrumentation_tests.py -I --test-apk ContentShellTest -vvv
 ```
 
 *** note
 This is assuming you have the exact same linux version on your host machine and
 in your laptop.

-But if you have different versions, lets say, ubuntu lucid on your laptop, and the newer ubuntu precise on your host machine, some binaries compiled on the host will not work on your laptop.
+But if you have different versions, lets say, Ubuntu Lucid on your laptop, and the newer Ubuntu Precise on your host machine, some binaries compiled on the host will not work on your laptop.
 In this case you will have to recompile these binaries in your laptop:
 
 ```shell
 # May need to install dependencies on your laptop.
 
 laptop$ sudo ./build/install-build-deps-android.sh
 
 # Rebuild the needed binaries on your laptop.
 
 laptop$ build/gyp_chromium -DOS=android
