+
+## Installation
+
+* Configuration file: `multivariate_config.xml`.
+* Image files: 
+  + `static/images/multivariate_workflowPositionImage.png`.
+  + `static/images/multivariate_workingExampleImage.png`.
+* Wrapper file: `multivariate_wrapper.R`.
+* R packages  
+  + **batch** from CRAN  
+  
+    ```r
+    install.packages("batch", dep=TRUE)  
+    ```
+
+  + **ropls** from Bioconductor  
+  
+    ```r
+    install.packages("batch", dep=TRUE)  
+    source("http://www.bioconductor.org/biocLite.R")  
+    biocLite("ropls")      
+    ```
+
+## Tests
+
+The code in the wrapper can be tested by running the `tests/multivariate_tests.R` in R.
+
+You will need to install **RUnit** package in order to make it run:
+```r
+install.packages('RUnit', dependencies = TRUE)
+```
+
+## News
+
+### CHANGES IN VERSION 2.3.2
+
+INTERNAL MODIFICATION  
+
+ * Modification of the `multivariate_wrapper.R` file to handle **ropls** package versions of 1.3.15 and above (i.e. after switching to S4 classes).
+    
+***
+
+### CHANGES IN VERSION 2.3.0
+
+NEW FEATURES  
+
+ * **Predictions** now available (see the 'Samples to be tested' argument).
+ * OPLS(-DA): **Predictive and Orthogonal VIP** are now computed (see the 'comments' section).
+ * **Multiclass PLS-DA** implemented (see the 'comments' section).
