+### Issue 1: ofxCvPiCam
 
 If you run into compiler errors with the [ofxCVPiCam](https://github.com/orgicus/ofxCvPiCam/) library on RPi2. Its because the MMAL Libraries have changed slightly. 
 
 You can resolve these issues by following [this guide] (https://github.com/orgicus/ofxCvPiCam/issues/3). Or for the short version just rename the libs folder in the ofxCvPiCam folder.
 
-<pre>
+```
 cd ~/openFrameworks/addons/ofxCvPiCam/
 mv libs old-libs
-</pre>
+```
+
+### Issue 2: ofxCv
+
+There are some issues with ofxCv and later versions of openFrameworks. You can resolve these issues by checking out a different branch of the repo. 
+
+*  First remove the current installation of ofxCv: 
+  ```
+  cd ~/openFrameworks/addons
+  sudo rm -r ofxCv 
+  ```
+* Clone a fresh copy of ofxCv
 
+  ```
+  git clone https://github.com/kylemcdonald/ofxCv.git
+  ```
+* Checkout branch according to oF version: 
+  * oF version < 0.9.8, checkout the VS2012-static branch.
+  * oF version = 0.9.8, checkout stable.

-There are some issues with ofxCv and later versions of openFrameworks.
+### Issue 3: glm:: errors in compile
 
-You can resolve these issues by checking out a different branch of the repo.
+Using oF 0.9.8 version's stable branch will negate the glm:: errors. If you were following oF's download guide previously, please remove the `opensourceFrameworks` folder as this is a fresh installation of oF. 
 
-If you have a version of oF which is less than 0.9.8, checkout the VS2012-static branch.
+```
+git clone -b stable --single-branch https://github.com/openframeworks/openFrameworks.git
+```
 
-Otherwise use the origin/stable branch.
+Follow the same instructions of building and compiling oF. No need to install dependencies for oF again if you had previously installed oF. Then follow the instructions the [same instructions to build Footfall](https://github.com/WatershedArts/Footfall/blob/master/docs/rpi.md).
