+  (also for certain informational messages). They generate <strong>Problem Markers</strong>
+  which visually indicate those problems to a user. The problems are highlighted on the Console,
+  populate the Problems view and shown in the editor. Problem markers are organized
+  into Error <img src="../images/icon_error.gif" alt="Error">,
+  Warning <img src="../images/icon_warning.gif" alt="Warning">
+  and Info<img src="../images/icon_info.gif" alt="Info">categories.

-view. If the file is not found, the icon appears on the project.</p>
+Normally a toolchain defines a set of Error Parsers to deal with output of each tool. It is possible
+to redefine that set on a per-project basis in project properties:
+</p>
+<p>
+  <ol>
+    <li>In the C/C++ Projects view, right-click the project, and select <strong>Properties</strong>.</li>
+    <li>Expand <strong>C/C++ Build</strong>.</li>
+    <li>Select <strong>Settings</strong>.</li>
+    <li>Click the <strong>Error Parsers</strong> tab.</li>
+    <li>In the <strong>Error parsers</strong> list, select error parsers.</li>
+    <li>Click <strong>OK</strong>.</li>
+  </ol>
+</p>
+<p>Note that the order of error parsers is significant. Normally an error parser will <i>consume</i>
+the line where it spotted an error/warning and the others down the line won't get a chance to parse it.
+</p>
 
-<p>You can define the properties on a per project basis in the New CDT Project 
+<p>CDT provides one special kind of error parser, <strong>CDT pushd/popd CWD Locator</strong>.
-wizard, in the C/C++ Projects view, or in the Navigator view. You can also define 
+This parser does not create problem markers but it is looking for output of <strong>pushd</strong>
-project properties in the Preferences window for future make projects.</p>
+and <strong>popd</strong> commands which are commonly used in makefiles to print the Current Working Directory (CWD).
+CDT can use this information to associate the file names appearing in the output relative to the CWD.
+Note that that kind of parser needs to be the first to be able to provide the CWD to the other parsers.
+</p>
 
-<p>To select error parsers:</p>
+<p>Most of the error parsers are configurable via regular expression patterns and a user can:
+</p>
+<p>
+<ul>
+  <li>Adjust a pattern to detect a problem more accurately,</li>
+  <li>Disable useless or proliferating problems (Note that it can have positive effect on performance of the console),</li>
+  <li>Create own error parser for a custom tool.</li>
+</ul>
+</p>
 
-<ol>
+<p>To customize Error parsers do following:
-  <li>Do one of the following:</li>
