+# Avoiding Common Mistakes
+I took some simple steps to make sure I avoid common mistakes when it comes to the security of my MediaGallery contract.
+
+The sections below describes the steps taken to mitigate against potential contract vulnerabilities. 
+
+## 1. Logic Bugs
+Simple programming mistakes can cause the contract to behave differently to its stated rules, especially on 'edge cases'.
+
+I have mitigated against this risk by:
+
+* Following Solidity coding standards and general coding best practices for safety-critical software.
+* Avoiding overly complex rules (even at the cost of some functionality) or complicated implementation (even at the cost of some gas).
+
+Note that I have chosen not to include a mechanism for fixing bugs during the life of the contract due to concern that this mechanism would itself be a serious vulnerability.
