## Usage

+### Patches
+[List of available patches](https://github.com/dudik/herbe/pulls?q=is%3Aopen+is%3Apr+label%3Apatch)
+
+To create a new patch you'll have to open a pull request with your changes. Append `.diff` to the pull request URL to get a downloadable diff file. Don't forget to prefix the title with `patch:` and to apply the `patch` label to it. For inspiration, look at [my Xresources patch](https://github.com/dudik/herbe/pull/11). Thank you.

+_Note: This patching method was heavily inspired by [dylan's sowm](https://github.com/dylanaraps/sowm)._
+
+### Dismiss a notification
+A notification can be dismissed either by clicking on it with `DISMISS_BUTTON` (set in config.h, defaults to left mouse button) or sending a `SIGUSR1` signal to it:
```shell
-herbe "This is a notification"
+$ pkill -SIGUSR1 herbe
```
-will display a notification for the duration set in `config.h` that says `This is a notification`
+Dismissed notifications return exit code 2.
+
+### Actions
+Action is a piece of shell code that runs when a notification gets accepted. Accepting a notification is the same as dismissing it, but you have to use either `ACTION_BUTTON` (defaults to right mouse button) or the `SIGUSR2` signal.
+An accepted notification always returns exit code 0. To specify an action:
+```shell
+$ herbe "Notification body" && echo "This is an action"
+```
+Where everything after `&&` is the action and will get executed after the notification gets accepted.
+
+### Newlines
+Every command line argument gets printed on a separate line by default e.g.:
+```shell
+$ herbe "First line" "Second line" "Third line" ...
+```
+You can also use `\n` e.g. in `bash`:
+```shell
+$ herbe $'First line\nSecond line\nThird line'
+```
+But by default `herbe` prints `\n` literally:
+```shell
+$ herbe "First line\nStill the first line"
+```
+Output of other programs will get printed correctly, just make sure to escape it (so you don't end up with every word on a separate line):
+```shell
+$ herbe "$(ps axch -o cmd:15,%cpu --sort=-%cpu | head)"
+```
+
+### Multiple notifications
+Notifications are put in a queue and shown one after another in order of creation (first in, first out). They don't overlap and each one is shown for its entire duration.
+
+### Notifications don't show up
+Most likely a running notification got terminated forcefully (SIGKILL or any uncaught signal) which caused the semaphore not getting unlocked. First, kill any `herbe` instance that is stuck:
+```shell
+$ pkill -SIGKILL herbe
+```
+Then just call `herbe` without any arguments:
+```shell
+$ herbe
+```
+Notifications should now show up as expected.
+
+Don't ever send any signals to `herbe` except these:
+```shell
+# same as pkill -SIGTERM herbe, terminates every running herbe process
+$ pkill herbe
+
+$ pkill -SIGUSR1 herbe
+$ pkill -SIGUSR2 herbe
+```
+And you should be fine. That's all you really need to interact with `herbe`.

The names of packages are different depending on which distribution you use.
For example, if you use [Void Linux](https://voidlinux.org/) you will have to install these dependencies:
## Configuration
herbe is configured at compile-time by editing `config.h`. Every option should be self-explanatory. There is no `height` option because height is determined by font size and text padding.
