 ## Preliminary set up
 In order to allow the MMA8451 software to run as a regular user, for example user ```pi``` (or any other user you might prefer), it is important that the software can access some of the system device file appropriately.
 
 In order to do that, please follow these instructions.
 * The file ```/sys/module/i2c_bcm2708/parameters/combined``` must be Read/Write for all users
-* The file ```/sys/module/i2c_bcm2708/parameters/combined``` must contain ```Y```
+* The file ```/sys/module/i2c_bcm2708/parameters/combined``` must contain ```Y``` (upper-case 'Y')
 The above can be achieved by manually setting the requirements via shell command, as follows:
 
-    ```sudo chmod 666 /sys/module/i2c_bcm2708/parameters/combined```
-    
-    ```sudo echo -n 1 > /sys/module/i2c_bcm2708/parameters/combined```
