+### Pre reqs
+
+Insatll kernel headers
+```
+sudo yum install kernel-devel
+```
+Note: make sure that correct kernel headers are installed for the current kernel, otheerwise maybe a update is needed.
+
+### Install kvaser driver
+
+#### Use the correct source
+Goto kvasser dir and untar the file: socketcan_kvaser_drivers_patch_asm_3.10.tar.gz
+
+``` 
+cd kvaser
+tar -xvf socketcan_kvaser_drivers_patch_asm_3.10.tar.gz 
+cd socketcan_kvaser_drivers/
+``` 
+Note: Non patched source downladed from kvaser will not work with kernel 3.10. So use the source in kvaser dir of this repo. 
+
+## 3 make 
+Read the README file in kvaser driver.
+These commands are from that README:
+```
+$ sudo make uninstall
+$ make

+```
+$ sudo modprobe can_dev
+$ sudo modprobe can
+$ sudo modprobe can_raw
+$ sudo modprobe kvaser_usb                        #not sure if needed
+$ sudo ip link set can0 type can bitrate 125000
+$ sudo ip link set up can0
