-### process-timeout
+## process-timeout
 
 Defaults to `300`. The duration processes like git clones can run before
 Composer assumes they died out. You may need to make this higher if you have a
 slow connection or huge vendors.
 
-### use-include-path
+## use-include-path
 
 Defaults to `false`. If `true`, the Composer autoloader will also look for classes
 in the PHP include path.
 
-### preferred-install
+## preferred-install
 
 Defaults to `auto` and can be any of `source`, `dist` or `auto`. This option
 allows you to set the install method Composer will prefer to use.
 
-### store-auths
+## store-auths
 
 What to do after prompting for authentication, one of: `true` (always store),
 `false` (do not store) and `"prompt"` (ask every time), defaults to `"prompt"`.
 
-### github-protocols
+## github-protocols
 
 Defaults to `["git", "https", "ssh"]`. A list of protocols to use when cloning
 from github.com, in priority order. You can reconfigure it to for example
 prioritize the https protocol if you are behind a proxy or have somehow bad
 performances with the git protocol.

-### http-basic
+## http-basic
 
 A list of domain names and username/passwords to authenticate against them. For
 example using `{"example.org": {"username": "alice", "password": "foo"}` as the
 value of this option will let Composer authenticate against example.org.
 
-### platform
+## platform
 
 Lets you fake platform packages (PHP and extensions) so that you can emulate a
 production env or define your target platform in the config. Example: `{"php":
 "5.4", "ext-something": "4.0"}`.
 
-### vendor-dir
+## vendor-dir
 
 Defaults to `vendor`. You can install dependencies into a different directory if
 you want to. `$HOME` and `~` will be replaced by your home directory's path in
 vendor-dir and all `*-dir` options below.
 
-### bin-dir
+## bin-dir
 
 Defaults to `vendor/bin`. If a project includes binaries, they will be symlinked
 into this directory.
 
-### cache-dir
+## cache-dir
 
 Defaults to `$COMPOSER_HOME/cache` on unix systems and
 `C:\Users\<user>\AppData\Local\Composer` on Windows. Stores all the caches used
 by Composer. See also [COMPOSER_HOME](03-cli.md#composer-home).
 
-### cache-files-dir
+## cache-files-dir
 
 Defaults to `$cache-dir/files`. Stores the zip archives of packages.
 
-### cache-repo-dir
+## cache-repo-dir
 
 Defaults to `$cache-dir/repo`. Stores repository metadata for the `composer`
 type and the VCS repos of type `svn`, `github` and `bitbucket`.
 
-### cache-vcs-dir
+## cache-vcs-dir
 
 Defaults to `$cache-dir/vcs`. Stores VCS clones for loading VCS repository
 metadata for the `git`/`hg` types and to speed up installs.
 
-### cache-files-ttl
+## cache-files-ttl
 
 Defaults to `15552000` (6 months). Composer caches all dist (zip, tar, ..)
 packages that it downloads. Those are purged after six months of being unused by
 default. This option allows you to tweak this duration (in seconds) or disable
 it completely by setting it to 0.
 
-### cache-files-maxsize
+## cache-files-maxsize
 
 Defaults to `300MiB`. Composer caches all dist (zip, tar, ..) packages that it
 downloads. When the garbage collection is periodically ran, this is the maximum
 size the cache will be able to use. Older (less used) files will be removed
 first until the cache fits.
 
-### prepend-autoloader
+## prepend-autoloader
 
 Defaults to `true`. If false, the Composer autoloader will not be prepended to
 existing autoloaders. This is sometimes required to fix interoperability issues
 with other autoloaders.
 
-### autoloader-suffix
+## autoloader-suffix
 
 Defaults to `null`. String to be used as a suffix for the generated Composer
 autoloader. When null a random one will be generated.
 
-### optimize-autoloader
+## optimize-autoloader
 
 Defaults to `false`. Always optimize when dumping the autoloader.
 
-### classmap-authoritative
+## classmap-authoritative
 
 Defaults to `false`. If `true`, the Composer autoloader will not scan the
 filesystem for classes that are not found in the class map. Implies
 'optimize-autoloader'.
 
-### github-domains
+## github-domains
 
 Defaults to `["github.com"]`. A list of domains to use in github mode. This is
 used for GitHub Enterprise setups.
 
-### github-expose-hostname
+## github-expose-hostname
 
 Defaults to `true`. If set to `false`, the OAuth tokens created to access the
 github API will have a date instead of the machine hostname.
 
-### notify-on-install
+## notify-on-install
 
 Defaults to `true`. Composer allows repositories to define a notification URL,
 so that they get notified whenever a package from that repository is installed.
 This option allows you to disable that behaviour.
