+# fancy-prompt [![Build status](https://travis-ci.org/doy/fancy-prompt.svg)](https://travis-ci.org/doy/fancy-prompt)
+
+`fancy-prompt` is an improved shell prompt with several useful features.
+
+## Screenshots
+
+## Features
+
+* Git integration
+* Battery meter
+* Customizable colors
+
+## Installation
+
+`fancy-prompt` is a command which generates prompt output directly. First,
+install the `fancy-prompt` binary itself:
+
+`cargo install fancy-prompt`
+
+Then, configure fancy-prompt for your shell:
+
+### `zsh`
+
+```
+function shell_prompt_precmd () {
+    PROMPT=`fancy-prompt --prompt-escape zsh $?`
+}
+precmd_functions+=(shell_prompt_precmd)
+```
+
+### `bash`
+
+```
+export PROMPT_COMMAND="__err=\$?;$PROMPT_COMMAND;PS1=\"\$(fancy-prompt --prompt-escape bash "\$__err")\""
+```
+
+### `fish`
+
+```
+function fish_prompt
+    fancy-prompt $status
+end
+```
+
+## Configuration
+
+You can customize the colors that `fancy-prompt` uses via the
+`FANCY_PROMPT_COLORS` environment variable. It should contain a `,`-separated
+list of key-value pairs separated by `=`. For instance:
+
+```
+export FANCY_PROMPT_COLORS=user_doy=bright_blue,host_lance=red
+```
+
+### Color names
+
+* `black`
+* `blue`
+* `cyan`
+* `green`
+* `magenta`
+* `red`
+* `white`
+* `yellow`
+* `bright_black`
+* `bright_blue`
+* `bright_cyan`
+* `bright_green`
+* `bright_magenta`
+* `bright_red`
+* `bright_white`
+* `bright_yellow`
+
+### Display element names
+
+* `user_%s`: Color of the username and the prompt character for that username.
+* `host_%s`: Color of the hostname and various highlight elements of the prompt
+  (to help visually differentiate between being logged into different hosts).
+* `path_not_writable`: Color of the path when you are in a directory without
+  write permissions.
+* `path_not_exist`: Color of the path when you are in a directory that no
+  longer exists.
+* `vcs_dirty`: Color of the VCS output when the local repository has changes
+  that are not in the upstream repository.
+* `vcs_error`: Color of the VCS output when there was an error determining
+  repository state.
+* `battery_full`: Color of the battery meter when the battery is above 80%.
+* `battery_warn`: Color of the battery meter when the battery is between 15%
+  and 40%.
+* `battery_crit`: Color of the battery meter when the battery is between 5% and
+  15%.
+* `battery_emerg`: Color of the battery meter when the battery is below 5%.
+* `battery_charging`: Color of the battery meter when the battery is charging.
+* `default`: Default color of unimportant parts of the prompt.
+* `error`: Color to use for errors in parts of the prompt that don't have their
+  own error color.
+
+## Contributing
+
+I am very interested in patches to make the prompt more useful or configurable.
+Currently it has a very limited amount of configurability because it works for
+me and I don't want to spend time on extra configurability that nobody will
+use, but if there is something you want, let me know (or send patches) and I'll
+see what i can do.
+
+One thing to keep in mind is that in order to be useful, the prompt needs to
+run as quickly as possible. Try to avoid features that add unnecessary latency
+to the prompt display.
