====== How to install a plugin? ======

===== I only have the the Java source file =====
Copy the *.java file to the ImageJ/Plugins folder or subfolder.

Go to the menu entry **Plugins>Compile and Run...** and select the Java file you copied.

If compiled successfully, go to **Help>Refresh Menus** or (better) restart ImageJ.

If the plugin has an underscore "_" in the name, it will appear in the Plugins menu (or submenu).

===== I have the *.class file =====

Copy the *.class file to the ImageJ/Plugins folder or subfolder.

Go to **Help>Refresh Menus** or (better) restart ImageJ.

If the plugin has an underscore "_" in the name, it will appear in the Plugins menu (or submenu).


===== I have the *.jar file =====
Copy the *.jar file to the ImageJ/Plugins folder

Go to **Help>Refresh Menus** or (better) restart ImageJ.

Jar files contain a plugin.config file that can specify where in the menu the entry will appear.

Jar files are zip compressed files, so you can investigate this easily.
