 Once compiled and installed you can use it via protoc like so:
 
-```
-protoc --php_out=. your.proto
-```
+    protoc --php_out=. your.proto
 
 This should generate the file "your.proto.php", which should be able to encode and decode protocol buffer messages. When using the generated PHP code you must include the "protocolbuffers.inc.php" file.
 
 
 Notes on Numbers
------
+----------------
 PHP uses signed integers, and depending on the platform may be 32 bit or 64 bit in size. Additionally PHP is typically compiled with IEEE 754 double precision floating point numbers, but may be compiled with single precision. This causes multiple problems for PHP using large numbers. As such the best appropimation is used when an exact representation is not available. On 32 bit platforms, signed integers are correct between -2^31 and 2^31-1, outside of that range floats are used. Double precision floats maintain integer accurancy up to 2^53, beyond that integers may not be precisce.
