-BUILDING
+## Building
 
 The Makefile.example is an example makefile that could be used to build these
 examples. Just edit the file according to your system and requirements first.
 
 Most examples should build fine using a command line like this:
 
-  $ `curl-config --cc --cflags --libs` -o example example.c
+    `curl-config --cc --cflags --libs` -o example example.c
 
 Some compilers don't like having the arguments in this order but instead
 want you do reorganize them like:
 
-  $ `curl-config --cc` -o example example.c `curl-config --cflags --libs`
+    `curl-config --cc` -o example example.c `curl-config --cflags --libs`
 
-*PLEASE* do not use the curl.haxx.se site as a test target for your libcurl
-applications/experiments. Even if some of the examples use that site as a URL
-at some places, it doesn't mean that the URLs work or that we expect you to
-actually torture our website with your tests!  Thanks.

 Each example source code file is designed to be and work stand-alone and
 rather self-explanatory. The examples may at times lack the level of error
