+How To Ask For Help
+-------------------
+
+If you are having difficulty building the driver after reading the below instructions, please email
+the `mongodb-user list`_ to ask for help. Please include in your email all of the following
+information:
+
+- The version of the driver you are trying to build (branch or tag).
+    - Examples: master branch, 1.0.2 tag
+- Host OS, version, and architecture.
+    - Examples: Windows 8 64-bit x86, Ubuntu 12.04 32-bit x86, OS X Mavericks
+- C Compiler and version.
+    - Examples: GCC 4.8.2, MSVC 2013 Express, clang 3.4, XCode 5
+- The output of ``./autogen.sh`` or ``./configure`` (depending on whether you are building from a
+  repository checkout or from a tarball). The output starting from "libbson was configured with
+  the following options" is sufficient.
+- The text of the error you encountered.
+
+Failure to include the relevant information will result in additional round-trip
+communications to ascertain the necessary details, delaying a useful response.
+Here is a made-up example of a help request that provides the relevant
+information:
+
+  Hello, I'm trying to build the C driver with SSL, from mongo-c-driver-1.1.0.tar.gz. I'm on Ubuntu
+  14.04, 64-bit Intel, with gcc 4.8.2. I run configure like::
+
+    $ ./configure --enable-sasl=yes
+    checking for gcc... gcc
+    checking whether the C compiler works... yes
+
+    ... SNIPPED OUTPUT, but when you ask for help, include full output without any omissions ...
+
+    checking for pkg-config... no
+    checking for SASL... no
+    checking for sasl_client_init in -lsasl2... no
+    checking for sasl_client_init in -lsasl... no
+    configure: error: You must install the Cyrus SASL libraries and development headers to enable SASL support.
+
+  Can you tell me what I need to install? Thanks!
