+<p>hi, and welcome to the first ~town golf challenge!</p>
+<p>in case you're not familiar with code golf - your task is to create the smallest
+program you can to perform a specific task. <a href="">here's a more detailed
+explaination</a>, including instructions on how to submitting your solution </p>
+<p>for now we'll keep it simple: your program has to print the ascii art tilde
+(pictured below) on stdin, without outputting anything else. you don't have to
+print the trailing spaces, and you may use any non-whitespace characters instead
+of ▉. have fun!</p>

+in short: put your file in ~/golf/<i>[challenge_name]</i>/. ensure that it's
+executable (chmod +x your_file) and that it has a shebang
+</p><hr><p>
+shebangs are those lines at the beginning of scripts that look like
+<code>#!/this</code>. they contain the path to the interpreter for the language
+that you're using, so people can launch them easily. some examples are:
+<ul>
+<li>for ruby - #!/usr/bin/ruby</li>
+<li>for python - #!/usr/bin/python</li>
+</ul>
+if you don't know where the interpreter is, you can use the <code>whereis</code>
+command. if you want to use a compiled language, such as C, you have to use a
+wrapper script. here are the ones that i know of:
+<ul>
+<li>for C/C++ - #!/home/dzwdz/bin/c</li>
+</ul>
