-    <para>So here we are.  System all installed and you are ready to
-      start programming.  But where to start?  What does FreeBSD
-      provide?  What can it do for me, as a programmer?</para>
-
-    <para>These are some questions which this chapter tries to answer.
-      Of course, programming has different levels of proficiency like
-      any other trade.  For some it is a hobby, for others it is their
-      profession.  The information in this chapter might be aimed
-      toward the beginning programmer; indeed, it could serve useful
-      for the programmer unfamiliar with the &os; platform.</para>

+    <title>在 FreeBSD 開發程式</title>
+    <para>好了我們開始吧！我想你的 FreeBSD 已經安裝好了，而且已經準備好要用它寫點程式了吧？
+      但是要從哪裡開始呢？&os; 有提供寫程式的程式或環境嗎？
+      身為 programer 的我可以做什麼呢？</para>
+
+    <para>本章試著回答你一些問題，當然，單就 programming 程度來說可分很多種層次，
+      有的人只是單純當興趣，有的則是他的專業，
+      本章主要內容是針對程式初學者，
+      當然，對於那些不熟 &os; 的程式開發者而言，本文件內容也是十分實用的。</para>

-      <listitem><para>Do not add new functionality unless an

-        it.</para></listitem>
+      <listitem><para>在整個程式還沒寫完前，不要增加新的功能。</para></listitem>
 
-      <listitem><para>It is as important to decide what a system is
-        not as to decide what it is. Do not serve all the world's
-        needs; rather, make the system extensible so that additional
-        needs can be met in an upwardly compatible
-        fashion.</para></listitem>
+      <listitem><para>另外一個重點就是，讓你自己選擇你的程式將會具有何種功能，
+        而不是讓別人決定，不想要去滿足全世界的需求，除非你想讓你的程式具有擴充性或相容性。</para></listitem>
 
-      <listitem><para>The only thing worse than generalizing from one
-        example is generalizing from no examples at
-        all. </para></listitem>
+      <listitem><para>千萬記住：在沒有相關經驗時，參考範例程式碼所寫出來的程式，
+        會比自己憑空寫出來的好。</para></listitem>
 
-      <listitem><para>If a problem is not completely understood, it is
-        probably best to provide no solution at all.</para></listitem>
+      <listitem><para>當你寫的程式沒辦法完全解決問題時，最好的方法就是不要試著要去解決它。</para></listitem>
 
-      <listitem><para>If you can get 90 percent of the desired effect
-        for 10 percent of the work, use the simpler
-        solution.</para></listitem>
+      <listitem><para>若用 10% 的心力就能輕鬆完成 90% 的工作份量，就用這個簡單法子吧。</para></listitem>
 
-      <listitem><para>Isolate complexity as much as
-        possible.</para></listitem>
+      <listitem><para>盡可能地簡化問題的複雜。</para></listitem>
 
-      <listitem><para>Provide mechanism, rather than policy. In
-        particular, place user interface policy in the client's
-        hands.</para></listitem>
+      <listitem><para>提供機制(mechanism)，而非原則(policy)。
+        比方說，把使用者介面選擇權交由使用者來決定。</para></listitem>
