+# Watson
+
+[Watson](https://tailordev.github.io/Watson) is a free and open-source time-tracker for
+[Linux](/wiki/linux.md) that uses the [command-line interface](/wiki/linux/shell.md).
+
+## Setup
+
+On most Linux distributions Watson can be installed with the `watson` package.
+Additionally Watson can be installed using Pythons pip package manager.
+The pip package is called ´td-watson`.
+Alternatively it can be installed via [GitHub](https://github.com/TailorDev/Watson).
+
+## Usage
+
+The following section describes various ways of usage of Watson.
+
+### Tracking Time and Displaying Tracked Time
+
+Time can be tracked by running the following command.
+This example tracks time to a project called `world-domination` and uses the tag `cats` and `dogs`.
+Additional tags can be appended or tags can be ommited if not needed.
+This should be adapted to specific needs.
+
+```sh
+watson start world-domination +cats +dogs
+```
+
+Alternatively the start time can be set in the past by adding the `--at` flag with a time.
+
+```sh
+watson start world-domination +cats +dogs --at 13:37
+```
+
+The tracking of the time can be stopped by running the following command.
+
+```sh
+watson stop
+```
+
+Afterwards the summary of the tracked time can be displayed by running the following command.
+
+```sh
+watson report
+```
+
+### Adding a Time Frame in Retrospect
+
+It can be useful to add time frames in retrospect if the starting and stopping of that task was
+forgotten at that time.
+For this the following command can be run.
+It works similarly to starting a time frame as explained in the
+[section above](#tracking-time-and-displaying-tracked-time).
+Additionally the start and stop time are specified with the `--from` and `--to` flags.
+
+```sh
+watson add --from "2018-03-20 12:00:00" --to "2018-03-20 13:00:00" programming +addfeature
+```
