+## Building your own NSS
+
+In order to use a debugger with the NSS library, it helps to build NSS yourself.
+Here's how I did it:
 
 First, read
 http://www.mozilla.org/projects/security/pki/nss/nss-3.11.4/nss-3.11.4-build.html
 and/or
 https://developer.mozilla.org/En/NSS_reference/Building_and_installing_NSS/Build_instructions
 
 Then, to build the most recent source tarball:
-```
- cd $HOME
- wget ftp://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_12_RTM/src/nss-3.12-with-nspr-4.7.tar.gz
- tar -xzvf nss-3.12-with-nspr-4.7.tar.gz
- cd nss-3.12/
- cd mozilla/security/nss/
- make nss_build_all
+
+```shell
+cd $HOME
+wget ftp://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_12_RTM/src/nss-3.12-with-nspr-4.7.tar.gz
+tar -xzvf nss-3.12-with-nspr-4.7.tar.gz
+cd nss-3.12/
+cd mozilla/security/nss/
+make nss_build_all
 ```
 
-Sadly, the latest release, 3.12.2, isn't available as a tarball, so you have to build it from cvs:
-```
- cd $HOME
- mkdir nss-3.12.2
- cd nss-3.12.2
- export CVSROOT=:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
- cvs login
- cvs co -r NSPR_4_7_RTM NSPR
- cvs co -r NSS_3_12_2_RTM NSS
- cd mozilla/security/nss/
- make nss_build_all

-# Linking against your own NSS
+## Linking against your own NSS
 
 Sadly, I don't know of a nice way to do this; I always do
-```
-hammer --verbose net > log 2>&1
-```
+
+    hammer --verbose net > log 2>&1
+
 then grab the line that links my app and put it into a shell script link.sh,
 and edit it to include the line
-```
-DIR=$HOME/nss-3.12.2/mozilla/dist/Linux2.6_x86_glibc_PTH_DBG.OBJ/lib
-```
-and insert a -L$DIR right before the -lnss3.
 
-Note that hammer often builds the app in one, deeply buried, place, then copies it into Hammer
-for ease of use.  You'll probably want to make your link.sh do the same thing.
+    DIR=$HOME/nss-3.12.2/mozilla/dist/Linux2.6_x86_glibc_PTH_DBG.OBJ/lib
 
-Then, after a source code change, do the usual "hammer net" followed by "sh link.sh".
+and insert a `-L$DIR` right before the `-lnss3`.
+
+Note that hammer often builds the app in one, deeply buried, place, then copies
+it into Hammer for ease of use. You'll probably want to make your `link.sh` do
+the same thing.
+
+Then, after a source code change, do the usual `hammer net` followed by
+`sh link.sh`.
 
 Then, to run the resulting app, use a script like
 
-# Running against your own NSS
-Create a script named 'run.sh' like this:
-```
+## Running against your own NSS
+
+Create a script named `run.sh` like this:
+
+```sh
 #!/bin/sh
 set -x
 DIR=$HOME/nss-3.12.2/mozilla/dist/Linux2.6_x86_glibc_PTH_DBG.OBJ/lib
 export LD_LIBRARY_PATH=$DIR
 "$@"
 ```
 
 Then run your app with
-```
-sh run.sh Hammer/foo
-```
+
+    sh run.sh Hammer/foo
 
 Or, to debug it, do
-```
-sh run.sh gdb Hammer/foo
-```
 
-# Logging
+    sh run.sh gdb Hammer/foo
+
+## Logging
 
 There are several flavors of logging you can turn on.
 
-  * SSLClientSocketNSS can log its state transitions and function calls using base/logging.cc.  To enable this, edit net/base/ssl\_client\_socket\_nss.cc and change #if 1 to #if 0.   See base/logging.cc for where the output goes (on Linux, it's usually stderr).
+*   `SSLClientSocketNSS` can log its state transitions and function calls using
+    `base/logging.cc`.  To enable this, edit `net/base/ssl_client_socket_nss.cc`
+    and change `#if 1` to `#if 0`. See `base/logging.cc` for where the output
+    goes (on Linux, it's usually stderr).
 
-  * HttpNetworkTransaction and friends can log its state transitions using base/trace\_event.cc.  To enable this, arrange for your app to call  base::TraceLog::StartTracing().  The output goes to a file named trace...pid.log in the same directory as the executable (e.g. Hammer/trace\_15323.log).

-  * NSS itself can log some events.  To enable this, set the envirnment variables SSLDEBUGFILE=foo.log SSLTRACE=99 SSLDEBUG=99 before running your app.

 Edit / Preferences / Protocols / SSL, and in the "RSA Keys List" box, enter

-127.0.0.1,9443,http,/home/dank/chromium/src/net/data/ssl/certificates/ok_cert.pem;127.0.0.1,9666,http,/home/dank/chromium/src/net/data/ssl/certificates/expired_cert.pem

 Then capture all tcp traffic on interface lo, and run your test.
 
-# Valgrinding NSS
+## Valgrinding NSS
 
 Read https://developer.mozilla.org/en/NSS_Memory_allocation and do
-```
-export NSS_DISABLE_ARENA_FREE_LIST=1
-```
-before valgrinding if you want to find where a block was originally
-allocated.
+
+    export NSS_DISABLE_ARENA_FREE_LIST=1
+
+before valgrinding if you want to find where a block was originally allocated.
 
 If you get unsymbolized entries in NSS backtraces, try setting:
-```
-export NSS_DISABLE_UNLOAD=1
-```
 
-(Note that if you use the Chromium valgrind scripts like tools/valgrind/chrome\_tests.sh or tools/valgrind/valgrind.sh these will both be set automatically.)
+    export NSS_DISABLE_UNLOAD=1
