+
+For Chromium Code Review, right click on the patchset table and select `OME`, 
+it will open all the files in this patchset.

[watk, 2017/03/02 23:13:48]

"this patchset" -> "the patchset"

+
+For Chromium Code Review, you can also right click on filename and select 

[watk, 2017/03/02 23:13:49]

"on a filename"

+`OME by link`.
+
+![Chromium Code Review by link](./images/open-by-link-cr.png)
+
+For any  *.chromium.org site, select the file path then right click and select 

[watk, 2017/03/02 23:13:49]

Remove double space before *.chromium.org

+
+## Installation
+
+1. Install the Chrome Extension `TODO will add link`

[watk, 2017/03/02 23:13:48]

Finish todo now?

+2. Install dependencies `pip install bottle sh`, you may need to install 
+   `python` and `python-pip` if you don't have `pip`.
+
+3. Start `omed.py`
+  
+    ```
+    git clone sso://user/chaopeng/ome ~/ome

[watk, 2017/03/02 23:13:49]

Change this to the Chrome checkout version.

+    python ~/ome/omed.py # you should set it on startup

[watk, 2017/03/02 23:13:49]

I would move this comment out of the code block into its own line and say
something like:

"It's convenient to configure your system to automatically run omed.py at
startup so that you don't have to remember to manually start it."

+    ```
+
+4. Create your `myeditor` as your editor's wrapper (see `myeditor-example/`) and 

[watk, 2017/03/02 23:13:49]

"Create a `myeditor` executable to be used for launching your editor, and add it
to your path. See `myeditor-example/`."

+   put it into path.
+5. Enjoy.
+
+## How it works
+
+In the Chrome Extension, I read the filepath and line number from right click,  
+then make a http call to `omed.py`. `omed.py` call `myeditor` to open your 

[watk, 2017/03/02 23:13:48]

"`omed.py` calls `myeditor`"

+editor.
