             <code>
               <br />&gt; python dotest.py -h
             </code>
+
+            <p>
+              Besides <code>dotest.py</code>, there is also <code>dosep.py</code>, which runs
+              multiple instances of <code>dotest.py</code> in parallel, thereby greatly
+              decreasing the time it takes to run the full testsuite. The number of concurrent
+              tests is controlled by the <code>LLDB_TEST_THREADS</code> environment variable and
+              defaults to the number of CPUs on your system. To pass additional options to
+              <code>dotest.py</code>, specify those options as an <code>-o</code> argument to
+              <code>dosep.py</code>. For example, the command
+            </p>
+            <code>python dosep.py -o "--executable bin/lldb -C bin/clang"</code>
+            <p>
+              will specify the lldb and clang executables to test for each dotest invocation.
+              <code>ninja check-lldb</code> is wrapper around <code>dosep.py</code>.

+            <h3>Running the test-suite remotely</h3>
+
+            <p>
+              Running the test-suite remotely is supported both with <code>dotest.py</code> and
+              <code>dosep.py</code>. The general process is the same as when running a local test
+              suite, but there are two things to have in mind:
+            </p>
+            <ul>
+              <li>
+                You must have the <code>lldb-server</code> running on the remote system, ready to
+                accept multiple connections. For more information on how to setup remote
+                debugging see the <a href="remote.html">Remote debugging</a> page.
+              </li>
+              <li>
+                You must tell the test-suite how to connect to the remote system. This is
+                achieved using the <code>--platform-name</code>, <code>--platform-url</code> and
+                <code>--platform-working-dir</code> parameters to <code>dotest.py</code>. These
+                parameters correspond to the <code>platform select</code> and <code>platform
+                connect</code> LLDB commands. You will usually also need to specify the compiler and
+                architecture for the remote system.
+              </li>
+            </ul>

             <h2>Building API reference documentation</h2>
             <p>
               LLDB exposes a C++ as well as a Python API. To build the reference documentation for these two APIs, ensure you have
