+### Software setup
+
+#### Obtain and Install Renesas Graphics Drivers
+
+See [here](http://wiki.projects.genivi.org/index.php/Hardware_Setup_and_Software_Installation/koelsch%26porter#M2_Porter_low_cost_board) and get 2 ZIP files from the link there.
+
+Note: You have to copy files manually because there is no shell-script
+in the current meta-renesas.
+
+1. Unzip the two downloads into a folder. In this example a temporary directory is used.
+        $ cd $HOME/AGL
+        $ mkdir binary-tmp
+        $ <unzip the two downloads into binary-tmp>
+
+   After this step there should be two files in binary-tmp:
+        R-Car_Series_Evaluation_Software_Package_for_Linux-*.tar.gz
+        R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-*.tar.gz
+
+2. Extract 2 tar.gz
+        tar xf R-Car_Series_Evaluation_Software_Package_for_Linux-*.tar.gz
+        tar xf R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-*.tar.gz
+
+3. Copy 2 files manually
+   1. Locate EVA_r8a7791_linux_sgx_binaries_gles2.tar.bz2 in the graphics
+   driver deliverable and copy it into the BSP layer. (need rename)
+          cp <path_to_file>/EVA_r8a7791_linux_sgx_binaries_gles2.tar.bz2 \
+          meta-renesas/meta-rcar-gen2/recipes-graphics/gles-module/\
+          gles-user-module/r8a7791_linux_sgx_binaries_gles2.tar.bz2
+
+   2. Locate SGX_KM_M2.tar.bz2 in the graphics driver deliverable and copy
+   it into the BSP layer.
+          cp <path_to_file>SGX_KM_M2.tar.bz2 \
+          meta-renesas/meta-rcar-gen2/recipes-kernel/gles-module/gles-kernel-module
+
+#### Build from the Source code
+
+You can build a R-Car2 M2 (porter) image using the following steps:
+
+1. Export TEMPLATECONF to pick up correct configuration for the build
+   > $ export TEMPLATECONF=/full/path/to/meta-renesas/meta-rcar-gen2/conf
+
+2. Run the following command:
+   > $ source poky/oe-init-build-env
+
+3. Build the minimal image of AGL Distribution
+   > $ bitbake agl-image-ivi
+
+### Deployment (SDCARD)
+
+Follow the instructions [here](http://wiki.projects.genivi.org/index.php/Hardware_Setup_and_Software_Installation/koelsch%26porter#Deployment_.28SDCARD.29)
+
+Note: Use `agl-image-ivi-porter.tar.bz2` as name of root file system archive.
