+# watson-starship
+
+A simple plugin for [Starship](https://github.com/starship/starship),
+which  shows the elapsed time of the current project.
+
+## Setup
+
+You'll need the Golang toolchain for this (version 1.23+).
+
+To build:
+
+```shell
+git clone https://github.com/TLINDEN/watson-starship.git
+cd watson-starship
+make
+make install
+```
+
+Then add this to your `~/.config/starship.toml`:
+
+```toml
+[custom.watson]
+when = "watson status  -e | grep -v 'No project'"
+style = "green"
+command = 'watson-starship'
+format = '\[[$output]($style)\]'
+```
+
+And add `${custom.watson}\` to your global `format` setting.
+
+## Getting help
+
+Although I'm happy to hear from watson-starship users in private email, that's the
+best way for me to forget to do something.
+
+In order to report a bug,  unexpected behavior, feature requests or to
+submit    a    patch,    please    open   an    issue    on    github:
+https://github.com/TLINDEN/watson-starship/issues.
