  * Mobile builds, with IE < 9 bug fixes and method compilation removed, may be created using the `mobile` modifier argument.
-~~~ bash
+```bash

  * Strict builds, with `_.bindAll`, `_.defaults`, and `_.extend` in [strict mode](http://es5.github.com/#C), may be created using the `strict` modifier argument.
-~~~ bash

 lodash strict

  * Underscore builds, containing only methods included in Underscore, may be created using the `underscore` modifier argument.
-~~~ bash

 lodash underscore

 Custom builds may be created in three ways:
 
  1. Use the `category` argument to pass the categories of methods to include in the build.<br>
     Valid categories are *"arrays"*, *"chaining"*, *"collections"*, *"functions"*, *"objects"*, and *"utilities"*.
-~~~ bash
+```bash
 lodash category=collections,functions
 lodash category="collections, functions"
-~~~
+```
 
  2. Use the `exclude` argument to pass the names of methods to exclude from the build.
-~~~ bash
+```bash
 lodash exclude=union,uniq,zip
 lodash exclude="union, uniq, zip"
-~~~
+```
 
  3. Use the `include` argument to pass the names of methods to include in the build.
-~~~ bash
+```bash
 lodash include=each,filter,map
 lodash include="each, filter, map"
-~~~
+```
 
 All arguments, except `backbone` with `underscore`, `exclude` with `include`, and `legacy` with `csp`/`mobile`, may be combined.
 
-~~~ bash
+```bash
 lodash backbone legacy category=utilities exclude=first,last
 lodash underscore mobile strict category=functions include=pick,uniq
