+# Powerline Theme
+
+A colorful theme, where shows a lot information about your shell session.
+
+## Provided Information
+
+* Current path
+* Current username and hostname
+* Current time
+* 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 [../../plugins/available/battery.plugin.bash](battery plugin))
+* SCM Repository status (e.g. Git, SVN)
+* The current Python environment (Virtualenv, venv, and Conda are supported) in use
+* The current Ruby environment (rvm and rbenv are supported) 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, but you can change this behavior by setting the value of the following variable:
+
+    POWERLINE_PROMPT_USER_INFO_MODE="sudo"
+
+For now, the only supported value is `sudo`, which hides the username and hostname, and shows an indicator when `sudo` has the credentials cached. Other values have no effect at this time.
+
+### Clock Format
+
+You can change the format using the following variable:
+
+    THEME_CLOCK_FORMAT="%H:%M:%S"
+
+The time/date is printed by the `date` command, so refer to its man page to change the format.
+
+### Segment Order
+
+The contents of the prompt can be "reordered", all the "segments" (every piece of information) can take any place. The currently available segments are:
+
+* battery
+* clock
+* cwd
+* in_vim
+* python_venv
+* ruby
+* scm
+* user_info
+
+A variables can be defined to set the order of the prompt segments:
+
+    POWERLINE_PROMPT="user_info scm python_venv ruby cwd"
+
+The example values above are the current default values, but if you want to remove anything from the prompt, simply remove the "string" that represents the segment from the variable.
