 # KTextEditor Document Preview Plugin
 
 ## Introduction
 
 This repository contains the KTextEditor Document Preview Plugin, a plugin for the editor [Kate](https://www.kate-editor.org/), the IDE [KDevelop](https://www.kdevelop.org/) or other software using the [KTextEditor](https://api.kde.org/frameworks/ktexteditor/html/index.html) framework.
 
-The plugin enables a live preview of the currently edited text document in the final format. For the display it uses the KParts plugin which is currently selected as the preferred one for the MIME type of the document. If there is no matching KParts, no preview is possible.

-Define some testing install dir:
-
-    export MYKATEPLUGINPATH=$HOME/mykateplugins

     mkdir build
     cd build

+    cmake .. -DCMAKE_INSTALL_PREFIX=$MYKTEPLUGINSPATH
     make
     make install
 
 ## Use the plugin
 
 Start Kate or KDevelop on the commandline, with adapted QT_PLUGIN_PATH (make sure to not use a session open in another running app instance):
 
-    export QT_PLUGIN_PATH=$MYKATEPLUGINPATH:$QT_PLUGIN_PATH
+    # check the used plugin installation path as it depends on the system
+    # and replace "_REPLACE_LIB_" with e.g. "lib", "lib64" or "lib/x86_64-linux-gnu"
+    export QT_PLUGIN_PATH=$MYKTEPLUGINSPATH/_REPLACE_LIB_/plugins:$QT_PLUGIN_PATH
     kate --startanon
     # or
     kdevelop --ps
 
 In Kate, go to `Settings / Configure Kate... / Application / Plugins` and enable the "Document Preview" plugin. A "Preview" tool view should appear on the right sidebar.
 
 In KDevelop, go to `Settings / Configure KDevelop... / Plugins` and make sure the "Document Preview" plugin is enabled. Then go to `Window / Add Tool View...` and select the "Preview" tool view. It should appear on the right sidebar.
