 Properties in this file often contain <#> index segments. These index segments serve to separate groups of similar properties from each other. The actual value of these indexes are not important, only that a given set of properties which all refer to the same logical item all use the same index. The following example is talking about two seperate properties, each uses a different index to distinguish it from the other.

  properties.0.name = testName1

 Update descriptor advice:
 -------------------------
 
 The update descriptor advice allows to override the default update descriptor generated by p2. Typically this is useful if an IU has been renamed and automatic update detection is still desired.
 
+```
  update.id = <id of IU>
  update.range = <range of the IU being updated>
  update.matchExp = {a match expression identifying the IU being updated}. (When this is specified the values of id and range are ignored) 
  update.severity = <0|1>
+```
 
 To allow updating a renamed artifact, you must provide a matchExp that matches both the old and new artifact names. For example, when renaming \*old\* feature to \*new\*:
 
+```
  update.matchExp = providedCapabilities.exists(pc | \
  pc.namespace == 'org.eclipse.equinox.p2.iu' && \
  (pc.name == 'old.feature.group' || \
  (pc.name == 'new.feature.group' && pc.version ~= range('\[0.0.0,$version$)'))))
+```
 
 These match expressions are written in the [p2 Query Language p2ql](/Equinox/p2/Query_Language_for_p2 "Equinox/p2/Query Language for p2").
 
 Property Advice:
 ----------------
 
+```
  properties.<#>.name = <propertyName>
  properties.<#>.value = <propertyValue>
+```
 
 Where <#> is an index for the property, <propertyName>, and <propertyValue> hold the name and value strings for the property.
 
 For example:
 
+```
  properties.0.name = testName1
  properties.0.value = testValue1
  properties.1.name = testName2
  properties.1.value = testValue2
+```
