+BIOP VSI READER
+---------------
+
+## Installation as an End User
+
+Simply activate the **PTBIOP** and **IBMP-CNRS** Update Sites in Fiji. It will be under
+
+Plugins > BIOP > BIOP VSI Reader
+
+## Installation in order to make modifications
+
+To edit this ActionBar, place the `BIOP_VSI_Reader.ijm` file in your `Plugins/ActionBar` folder. 
+
+Then you can open it in Fiji. To work in debug mode, uncomment line 36
+
+```lang=java
+runFrom = "jar:file:BIOP/BIOP_VSI_reader.jar!/BIOP_VSI_reader.ijm";
+
+33. //////////////////////////////////////////////////////////////////////////////////////////////
+34. // The line below is for debugging. Place this VSI file in the ActionBar folder within Plugins
+35. //////////////////////////////////////////////////////////////////////////////////////////////
+36. //runFrom = "/plugins/ActionBar/BIOP_VSI_reader.ijm";
+
+```
+
+When you are finished, you must re-comment the above line, and repackage the file as a JAR. You can have a look at the `updataJar.bat` file in this repository. 
+Alternatively, opening the JAR using winRAR or 7-ZIP and placing the modified IJM file inside works just fine.
