+These following `vulkan`-specific environment variables are necessary to build our branch of mesa successfully:

+    export VK_ICD_FILENAMES=/home/$USER/opt/lsoc_mesa/share/vulkan/icd.\

 Now change back to the base `~/opt` directory and clone the `mesa` git repo from the `mesa` gitlab instance. Change to the `mesa` directory. Create a build directory and cd into it.
 
     cd ~/opt
-    git clone https://gitlab.freedesktop.org/mesa/mesa.git
+    git clone https://gitlab.freedesktop.org/vivekvpandya/mesa.git
     cd mesa
     mkdir build && cd build
 
 In order to configure `mesa` for building and installation run the following command. Again, it is *very* important to specify `prefix=/home/$USER/opt/lsoc_mesa` because as mentioned above we need these files for development purposes, but we do not want to corrupt or interfere with our *system* `mesa` libraries.

 After configuration has completed, run ninja to build and install the `mesa` libraries.
