## General Information
+
+ 
The *pkg-plugin-stats* plugin is used for displaying package stats during:
+
+ 
* pre-install
+ 
* post-install
+ 
* pre-deinstall
+ 
* post-deinstall
+
+ 
## How to build the plugin?
+
+ 
In order to build the plugin enter into the plugin's directory and run make(1), e.g.:
+
+ 
	$ cd /path/to/pkg-plugins-stats
+ 
	$ make
+
+ 
Once the plugin is built you can install it using the following command:
+
+ 
	$ make install
+
+ 
The plugin will be installed as a shared library in ${PREFIX}/lib/libpkg-plugin-stats.so
+
+ 
## Configuring the plugin
+
+ 
In order to configure the plugin simply copy the *stats.conf* file to the pkgng plugins directory,
+ 
which by default is set to */usr/local/etc/pkg/plugins*, unless you've specified it elsewhere by
+ 
using the *PKG\_PLUGINS\_DIR* option.
+
+ 
	$ cp /path/to/pkg-plugins-stats/stats.conf /usr/local/etc/pkg/plugins/
+
+ 
## Testing the plugin
+
+ 
To test the plugin, first check that it is recongnized and
+ 
loaded by pkgng by executing the `pkg plugins` command:
+
+ 
	$ pkg plugins
+ 
	NAME       DESC                                VERSION    LOADED
+ 
	stats      Plugin for displaying package stats 1.0        YES
+
+ 
If the plugin shows up correctly then you are good to go!
+
+ 
Now go ahead and install/deintall a package and see it in action! :)
