     <title>Obtaining Nix</title>

-      Nix can be obtained from its <ulink
-        url='http://losser.st-lab.cs.uu.nl:12080/repos/trace/nix/trunk'>Subversion 
+      The easiest way to obtain Nix is to download a <ulink

+        distribution.</ulink>  
+    </para>
+
+    <para>
+      Alternatively, the most recent sources of Nix can be obtained from its
+      <ulink url='https://svn.cs.uu.nl:12443/repos/trace/nix/trunk'>Subversion 
         repository</ulink>.  For example, the following command will check out
       the latest revision into a directory called <filename>nix</filename>:
     </para>
 
     <screen>
-$ svn checkout http://losser.st-lab.cs.uu.nl:12080/repos/trace/nix/trunk nix</screen>
+$ svn checkout https://svn.cs.uu.nl:12443/repos/trace/nix/trunk nix</screen>

     <title>Building Nix</title>
 
     <para>
-      To build Nix, do the following:
+      After unpacking or checking out the Nix sources, issue the following
+      commands:
     </para>
 
     <screen>
-$ autoreconf -i
 $ ./configure <replaceable>options...</replaceable>
 $ make
 $ make install</screen>
 
     <para>
-      Currently, the only useful switch for <command>configure</command> is
-      <option>--prefix=<replaceable>prefix</replaceable></option> to specify
-      where Nix is to be installed.  The default installation directory is

+      the command:
+    </para>
+
+    <screen>
+$ autoreconf -i</screen>
+
+    <para>
+      The installation path can be specified by passing the
+      <option>--prefix=<replaceable>prefix</replaceable></option> to
+      <command>configure</command>.  The default installation directory is
       <filename>/nix</filename>.  You can change this to any location you like.
-      You should ensure that you have write permission to the installation
-      prefix. 
+      You must have write permission to the <replaceable>prefix</replaceable>
