 ## Build instructions
 
 To build Chrome:
-```
-cd /path/to/chrome/src
-ninja -C out/Debug chrome
-```
 
-Specify `out/Release` for a release build. I recommend setting up an alias so that you don't need to type out that build directory path.
+    cd /path/to/chrome/src
+    ninja -C out/Debug chrome
 
-If you want to build all targets, use `ninja -C out/Debug all`. It's faster to build only the target you're working on, like 'chrome' or 'unit\_tests'.

 ## Android
 
-Identical to Linux, just make sure `OS=android` is in your `GYP_DEFINES`. You want to build one of the _apk targets, e.g. `content_shell_apk`._

 ## Windows
 
-Similar to Linux. It uses MSVS's `cl.exe`, `link.exe`, etc. so you still need to have VS installed. To use it, open `cmd.exe`, go to your chrome checkout, and run:
-```
-set GYP_DEFINES=component=shared_library
-python build\gyp_chromium
-ninja -C out\Debug chrome.exe

-You can also set `GYP_GENERATORS=ninja,msvs-ninja` to get both VS projects generated if you want to use VS just to browse/edit (but then gyp takes twice as long to run).

-If you're using Express or the Windows SDK by itself (rather than using a Visual Studio install), you'll need to run from a vcvarsall command prompt.

 ### Debugging
 
 Miss VS for debugging?
+
 ```
 devenv.com /debugexe chrome.exe --my-great-args "go here" --single-process etc
 ```
 
-Miss Xcode for debugging? Read http://dev.chromium.org/developers/debugging-on-os-x/building-with-ninja-debugging-with-xcode

 ### Without Visual Studio
 
-That is, building with just the WinDDK. This is documented in the [regular build instructions](http://dev.chromium.org/developers/how-tos/build-instructions-windows#TOC-Setting-up-the-environment-for-building-with-Visual-C-2010-Express-or-Windows-7.1-SDK).

 ## Tweaks
 
 ### Building through errors
-Pass a flag like `-k3` to make Ninja build until it hits three errors instead of stopping at the first.

 ### Parallelism
-Pass a flag like `-j8` to use 8 parallel processes, or `-j1` to compile just one at a time (helpful if you're getting weird compiler errors).  By default Ninja tries to use all your processors.

 ### More options
+
 There are more options. Run `ninja --help` to see them all.
 
 ### Custom build configs
 
-You can write a specific build config to a specific output directory via the `-G` flags to gyp.  Here's an example from jamesr:
-`build/gyp_chromium -Gconfig=Release -Goutput_dir=out_profiling -Dprofiling=1 -Dlinux_fpic=0`

 ## Bugs
 
-If you encounter any problems, please file a bug at http://crbug.com/new with label `ninja` and cc `thakis@` or `scottmg@`.  Assume that it is a bug in Ninja before you bother anyone about e.g. link problems.
