183<title>Finding Installed Package Documentation</title>
184<body>
185
186<p>
187Many packages come with their own documentation. Sometimes, the <c>doc</c> USE
188flag determines whether the package documentation should be installed or not.
189You can check the existence of a <c>doc</c> USE flag with the <c>emerge -vp
190&lt;package name&gt;</c> command.

200You can enable or disable the <c>doc</c> USE flag either globally in the
201<path>/etc/make.conf</path> file or per package in the
202<path>/etc/portage/package.use</path> file. The <uri
203link="?part=2&amp;chap=2">USE Flags</uri> chapter covers this aspect in detail.

206<p>
207Once the package installed, its documentation is generally found in a
208subdirectory named after the package under the <path>/usr/share/doc</path>
209directory. You can also list all installed files with the <c>equery</c> tool
210which is part of the <c>app-portage/gentoolkit</c> <uri
211link="/doc/en/gentoolkit.xml">package</uri>.
