 # Building TELEMAC-MASCARET on Windows
 
-This provides a set of scripts and a configuration file allowing to build TELEMAC-MASCARET on Windows using Mingw-w64.
+This repository provides a batch script and configuration files to build TELEMAC-MASCARET on Windows using Mingw-w64.
+
+The build includes the following dependencies:
+- MED (requires HDF5): add support for the MED file format.
+- MPI: enable runtime parallelism, using the latest implementation of Microsoft MPI. Also requires:
+    - METIS: used for partioning the mesh during a parallel run.
+- MUMPS: parallel direct solver which is only used by ARTEMIS. Also requires:
+    - MPI
+    - OpenBLAS (includes LAPACK)
+    - ScaLAPACK
+- AED2: activate more processes in WAQTEL.
+- GOTM: allow the use of the General Ocean Turbulence Model in TELEMAC-3D.
 
 ## Prerequisites:

 Note: if you don't install Mingw-w64 in `C:\`, you will need to add its `bin` directory to your `PATH`.

-## Building and installing TELEMAC-MASCARET dependencies
+## Building and installing TELEMAC-MASCARET
 
-TELEMAC-MASCARET can be built with or without several dependencies, which are listed below:
-- MED (requires HDF5): add support for the MED file format.
-- MPI: enable runtime parallelism, using the latest implementation of Microsoft MPI. Also requires:
-    - METIS: used for partioning the mesh during a parallel run.
-- MUMPS: parallel direct solver which is only used by ARTEMIS. Also requires:
-    - MPI
-    - OpenBLAS (includes LAPACK)
-    - ScaLAPACK
-- AED2: activate more processes in WAQTEL.
-- GOTM: allow the use of the General Ocean Turbulence Model in TELEMAC-3D.
+Once all software prerequisites have been installed and the proxy environment variables have been defined if necessary, TELEMAC-MASCARET can be built using the provided batch file. The only mandatory argument is the installation path, e.g.,
+to install TELEMAC-MASCARET in `C:\telemac`:
 
-These dependencies can be installed using the provided `build-telemac-deps.bat` script, as follows:
 ```
-C:\>build-telemac-deps C:\telemac-deps
+C:\wintel>build-telemac C:\telemac
 ```
 
-This will **download** and **build** all dependencies, and **install** them to the provided path, which is `C:\telemac-deps` in this example.
+This will **download** , **build** and **install** a full setup of the current development version of TELEMAC-MASCARET (i.e. the `main` branch) in the provided folder, which is `C:\telemac` in this example.
 
-## Building TELEMAC-MASCARET
+To build a specific version, you need to specify it using the `/v` switch, e.g:
 
-Once you have built the dependencies, you can build TELEMAC-MASCARET:
-- Clone the repository:
-```
-C:\>git clone https://gitlab.pam-retd.fr/otm/telemac-mascaret.git
-```
-- Copy the pysource batches from the `config` directory to TELEMAC-MASCARET `configs` directory:
-```
-C:\>xcopy /e/y wintel\config telemac-mascaret\configs\
-```
-- Edit both pysource batches to set the dependencies path, such as below:
 ```
-set TELEMACDEPS=C:\telemac-deps
-```
-- Setup TELEMAC-MASCARET environment by launching one of the pysource batch:
-```
-C:\>telemac-mascaret\configs\pysource.win.bat
-```
-- Build TELEMAC-MASCARET:
-```
-C:\>compile_telemac.py
+C:\wintel>build-telemac C:\telemac /v V8P4
 ```
+
+For now, the only supported stable version is V8P4.
+
+If the compilation went fine, the last message you will get should be `My work is done`.
