+## Compile Scripts for Vendor VHDL Libraries
+
+Vendors like Altera and Xilinx have there own simulation libraries, especially for primitives and hard macros. These libraries can not be shipped with GHDL, but we offer prepared compile scripts to pre-compile a vendor library, if the vendor tool is present on the computer.
+
+There are also popular simulation and verification libraries, which can be pre-compile.
+
+The compilation scripts are writen in shell languages: PowerShell for Windows and Bash for Linux. There are no further requirements.
+
+##### Supported Vendors Libraries
+
+ - Altera Quartus-II (15.x):
+     - lpm, sgate

+
+---------------------------------------------------------------------
+### Compiling on Windows
+
+ - **Step 1 - Configure the scripts**
+    Please open the `config.psm1` file and set the dictionary entries for the installed
+    vendor tools to the appropriate directory to your tool's installation folder.
+
+    `config.psm1`:
+
+        $InstallationDirectory = @{
+          "AlteraQuartusII" = "C:\Altera\15.0";
+          "XilinxISE" =       "C:\Xilinx\14.7";
+          "XilinxVivado" =    "C:\Xilinx\Vivado\2015.3";
+          "OSVVM" =           "D:\git\GitHub\osvvm";
+          "VUnit" =           "D:\git\GitHub\vunit"
+        }
+
+ - **Step 2 - Browse to your simulation working directory**
+    ```PowerShell
+    PS> cd <MySimulationFolder>
+    ```
+
+ - **Step 3 - Start the compilation script(s)**
+    ```PowerShell
+    PS> <GHDL>\libraries\vendors\compile-altera.ps1 -All
+    PS> <GHDL>\libraries\vendors\compile-xilinx-ise.ps1 -All
+    PS> <GHDL>\libraries\vendors\compile-xilinx-vivado.ps1 -All
+    PS> <GHDL>\libraries\vendors\compile-osvvm.ps1 -All
+    PS> <GHDL>\libraries\vendors\compile-vunit.ps1 -All
+    ```
+
+ - **Step 4 - Viewing the result**
+    This creates vendor directories in your current working directory and compiles the vendor files into them.
+
+    ```PowerShell
+    PS> dir
+        Directory: D:\temp\ghdl
+
+    Mode           LastWriteTime       Length Name
+    ----           -------------       ------ ----
