- Removed redundant output of the test command.
- Reduced the number of steps to three and wrote them as succintly as
  possible.
- Added the clarifying notes separately at the end.

 To reproduce on a performance try bot:
-1. Create new git branch or check out existing branch.
-2. Edit tools/run-perf-test.cfg (instructions in file) or \
-third_party/WebKit/Tools/run-perf-test.cfg.
-  a) Take care to strip any src/ directories from the head of \
-relative path names.
-  b) On desktop, only --browser=release is supported, on android \
---browser=android-chromium-testshell.
-  c) Test command to use: %(command)s
-3. Upload your patch. --bypass-hooks is necessary to upload the changes you \
-committed locally to run-perf-test.cfg.
-   Note: *DO NOT* commit run-perf-test.cfg changes to the project repository.
-   $ git cl upload --bypass-hooks
-4. Send your try job to the try server. \
-[Please make sure to use appropriate bot to reproduce]
-   $ git cl try -m tryserver.chromium.perf -b <bot>
+ 1. Edit run-perf-test.cfg
+ 2. Upload your patch with: $ git cl upload --bypass-hooks
+ 3. Send to the try server: $ git cl try -m tryserver.chromium.perf -b <bot>
+
+Notes:
+ a) Follow the in-file instructions in run-perf-test.cfg.
+ b) run-perf-test.cfg is under tools/ or under third_party/WebKit/Tools.
+ c) Do your edits preferably under a new git branch.
+ d) --browser=release and --browser=android-chromium-testshell are supported
+    depending on the platform (desktop|android).
+ e) Strip any src/ directories from the head of relative path names.
+ f) Make sure to use the appropriate bot on step 3.
