+# Powerline Multiline Theme
+
+Colorfull multiline theme, the first line shows information about your shell session (divided into two parts, left and right), the second one is where the shell commands are introduced.
+
+**IMPORTANT:** This theme has a requirement, [a font with the Powerline symbols](https://github.com/powerline/fonts) need tu be used in your terminal emulator, otherwise, the prompt won't be displayed correctly.
+
+## Information provided
+
+* Current path
+* Current username and hostname
+* An indicator when connected by SSH
+* An indicator when sudo has the credentials cached (see the sudo manpage for more info about this)
+* An indicator when the current shell is inside the Vim editor
+* Battery charging status (depends on the battery plugin)
+* Repository status
+* The current Python enviroment (Virtualenv, venv, and Conda are supported) in use
+* The current Ruby enviroment (RVM) in use
+* Last command exit code (only shown when the exit code is greater than 0)
+
+## Configuration
+
+This theme is pretty configurable, all the configuration is done by setting environment variables.
+
+### User information
+
+By default, the username and hostname are shown at the right side, but you can change this behavior setting the value of the following variable:
+
+    POWERLINE_PROMPT_USER_INFO_MODE
+
+for now, the only supported value is `sudo`, that hides the username and hostname, and shows an indicator when the sudo has the credentials cached. Any other value has no effect.
+
+### Clock format
+
+By default, the current time is shown at the right side, you can change the format with the variable:
+
+    POWERLINE_PROMPT_CLOCK_FORMAT="%H:%M:%S"
+
+the date is printed by the `date` command, so refer to its man page to change the format.
+
+### Segment order
+
+Both prompt sides can be "reordered", all the "segments" (every piece of information) can take any place, the current available segments are:
+
+* battery
+* clock
+* cwd
+* in_vim
+* python_venv
+* rvm
+* scm
+* user_info
+
+Two variables can be defined to set the order of the prompt segments:
+
+    POWERLINE_LEFT_PROMPT="scm python_venv rvm cwd"
+    POWERLINE_RIGHT_PROMPT="in_vim clock battery user_info"
+
+the example values are the defaults, but if you want to remove something else from the prompt, simply remove the "string" that represents the segment from the corresponding variable.
