 How to install or upgrade
 =========================
 
-The easiest way to install this plugin is by using the Plugin Manager:
-from the "Plugins" menu, choose the "Plugin Manager" and "Show Plugin
-Manager". Select the "Snippets" plugin and choose "install" and follow
-the instructions on the screen.
+The easiest way to install this plugin is by using the Plugins Admin.
+From the "Plugins" menu, choose the "Plugins Admin".
+Search for "Snippets" plugin, choose "install" and follow the instructions on the screen.
 
-To manually install the plugin, copy ``NppSnippets.dll`` to the
-``plugins`` directory and copy ``Template.sqlite`` to the
-``plugins/config`` directory in the user's "Application Data" directory
-and name it ``NppSnippets.sqlite``. On my Windows 7 machine this
-directory is ``C:\Users\Frank\AppData\Roaming\Notepad++\plugins\config``.
+To manually install the plugin, copy all the files in archive to the ``plugins/NppSnippets`` directory
+in the Notepad++ installation directory typically in the ``Program Files`` directory.
+You may need to create that directory.
 Then (re)start Notepad++.
 
-You can place the database in the ``plugins/config`` directory in the
-Notepad++ installation directory typically in the ``Program Files``
-directory, but this could result in a read-only database due to file
-permissions and/or User Account Control (UAC). Therefore it is advised
-to put it in your ``AppData`` directory.
-
-    From `issue #9`_:
-    I noticed when I change files with different languages of my progect it takes 2-3 seconds delay when plugin load snippets for this language (for example HTML to PHP).
-
-You can also specify a custom path (like a shared network path or your
-Dropbox directory) for your database by manually editing the
-``NppSnippets.ini`` file and adding a ``DBFile`` entry pointing to the
-full path name of the database. The ``NppSnippets.ini`` is normally in
-your ``AppData`` directory.
-
-When you automatically upgrade through the Plugin Manager your database
+When you automatically upgrade through the Plugin Admin your database
 is not touched. If you are manually upgrading at least replace the
 existing dll. It is up to you if you override your own database with the
 template database provided in the archive. If you have not changed
 existing snippets or added your own, it is recommended to use the
 database in the archive.
