+## [v0.12.1] - 2023-06-18
+### :boom: BREAKING CHANGES
+- due to [`e11177f`](https://github.com/JakeStanger/ironbar/commit/e11177fea3095560057278d71cebca01bed295d6) - add sensible class names for icon labels *(commit by [@JakeStanger](https://github.com/JakeStanger))*:
+
+  Where both textual and image icons are supported, CSS classes have changed to better reflect their targets. `.icon` has changed to `.icon-box` and `.icon` now targets the underlying element. `.label` has been changed to `.icon.text-icon`. This affects icons on the **music**, **workspaces**, and **clipboard** modules.

+- due to [`dea6641`](https://github.com/JakeStanger/ironbar/commit/dea66415c2e11e34ba44d016aaa6cfb4ef7b9f9b) - module-level `name` and `class` options *(commit by [@JakeStanger](https://github.com/JakeStanger))*:
+
+  To allow for the `name` property, any widgets that were previously targeted by name should be targeted by class instead. This affects **all modules and all popups**, as well as several widgets inside modules. **This will break a lot of rules in your stylesheet**. To attempt to mitigate the damage, a migration script can be found [here](https://raw.githubusercontent.com/JakeStanger/ironbar/master/scripts/migrate-styles.sh) that should get you most of the way.

 ## Features
 
-- First-class support for Sway and Hyprland, but should (mostly) work on any wlroots compositor.
-- Fully themeable with CSS and hot-loaded styles. 
-- Support for multiple configuration languages.
-- Popups used by widgets to show rich content and controls on click.
-- Out of the box widgets which can be used to create anything from a lightweight to a more traditional desktop experience.
-- Ability to create custom widgets (including popups), run scripts and inject dynamic content.

 ## Running
 
-All of the above installation methods provide a binary called `ironbar`.
+Once installed, you will need to create a config and optionally a stylesheet in `.config/ironbar`.
+See the [Configuration Guide](https://github.com/JakeStanger/ironbar/wiki/configuration-guide) and [Style Guide](https://github.com/JakeStanger/ironbar/wiki/styling-guide) for full details.
+
+Ironbar can be launched using the `ironbar` binary.
+
+Log verbosity can be changed using `IRONBAR_LOG` or `IRONBAR_FILE_LOG`. You can use any of `error`, `warn`, `info`, `debug` or `trace`.
 
-You can set the `IRONBAR_LOG` or `IRONBAR_FILE_LOG` environment variables to 
-`error`, `warn`, `info`, `debug` or `trace` to configure the log output level.
 These default to `IRONBAR_LOG=info` and `IRONBAR_FILE_LOG=error`.
+
 File output can be found at `~/.local/share/ironbar/error.log`.
 
-## Configuration
+## Status
 
-Ironbar gives a lot of flexibility when configuring, including multiple file formats
-and options for scaling complexity: you can use a single config across all monitors,
-or configure different/multiple bars per monitor.
+Ironbar is an **alpha** project. 
+It is unfinished and subject to constant breaking changes, and will continue that way until the foundation is rock solid.
 
-A full configuration guide can be found [here](https://github.com/JakeStanger/ironbar/wiki/configuration-guide).
+If you would like to take the risk and help shape development, any bug reports, feature requests and discussion is welcome.
 
-## Styling
+I use Ironbar on my daily driver, so development is active. Features aim to be stable and well documented before being merged.
 
-To get started, create a stylesheet at `.config/ironbar/style.css`. Changes will be hot-reloaded every time you save the
-file.
-
-A full styling guide can be found [here](https://github.com/JakeStanger/ironbar/wiki/styling-guide).
-
-## Project Status
-
-This project is in alpha, but should be usable.
-Everything that is implemented works and should be documented.
-Proper error handling is in place so things should either fail gracefully with detail, or not fail at all.
-
-There is currently room for lots more modules, and lots more configuration options for the existing modules.
-The current configuration schema is not set in stone and breaking changes could come along at any point;
-until the project matures I am more interested in ease of use than backwards compatibility.
-
-A few bugs do exist, and I am sure there are plenty more to be found.
-
-The project will be *actively developed* as I am using it on my daily driver.
-Bugs will be fixed, features will be added, code will be refactored.

+Ironbar includes a simple IPC server which can be used to control it programmatically at runtime.
+
+It also includes a command line interface, which can be used for interacting with the IPC server.
+
+# CLI
+
+This is shipped as part of the `ironbar` binary. To view commands, you can use `ironbar --help`. 
+You can also view help per-command, for example using `ironbar set --help`.
+
+Responses are handled by writing their type to stdout, followed by any value starting on the next line.
+Error responses are written to stderr in the same format.
+
+Example:
+
+```shell
+$ ironbar set subject world
+ok
+
+$ ironbar get subject
+ok
+world
+```
+
+# IPC
+
+The server listens on a Unix socket. 
+This can usually be found at `/run/user/$UID/ironbar-ipc.sock`.
+
+Commands and responses are sent as JSON objects, denoted by their `type` key.
+
+The message buffer is currently limited to `1024` bytes. 
+Particularly large messages will be truncated or cause an error.
+
+## Commands
+
+### `ping`
+
+Sends a ping request to the IPC.

+In some configuration locations, Ironbar supports dynamic values, 
+meaning you can inject content into the bar from an external source.
+
+Currently two dynamic content sources are supported - scripts and ironvars.
+
+## Dynamic String
+
+Dynamic strings can contain any mixture of static string elements, scripts and variables.
+
+Scripts should be placed inside `{{double braces}}`. Both polling and watching scripts are supported.
+
+Variables use the standard `#name` syntax. Variables cannot be placed inside scripts.
+
+To use a literal hash, use `##`. This is only necessary outside of scripts.
+
+Example:
+
+```toml
+label = "{{cat greeting.txt}}, #subject"
+```
+
+## Dynamic Boolean
+
+Dynamic booleans can use a single source of either a script or variable to control a true/false value.
+
+For scripts, you can just write these directly with no notation. 
+Only polling scripts are supported. 
+The script exit code is used, where `0` is `true` and any other code is `false.
+
+For variables, use the standard `#name` notation. 
+An empty string, `0` and `false` are treated as false. 
+Any other value is true.
+
+Example:
+
+```toml
+show_if = "exit 0" # script
+show_if = "#show_module" # variable
+```

+Since the bar is GTK-based, it uses [GTK's implementation of CSS](https://docs.gtk.org/gtk3/css-overview.html),
 which only includes a subset of the full web spec (plus a few non-standard properties).
 
 The below table describes the selectors provided by the bar itself.
 Information on styling individual modules can be found on their pages in the sidebar.

-| `#bar #start`  | Bar left or top modules container box     |
-| `#bar #center` | Bar center modules container box          |
-| `#bar #end`    | Bar right or bottom modules container box |
-| `.container`   | All of the above                          |
+| Selector       | Description                                |
+|----------------|--------------------------------------------|
+| `.background`  | Top-level window.                          |
+| `#bar`         | Bar root box.                              |
+| `#bar #start`  | Bar left or top modules container box.     |
+| `#bar #center` | Bar center modules container box.          |
+| `#bar #end`    | Bar right or bottom modules container box. |
+| `.container`   | All of the above.                          |
+| `.popup`       | Any popup box.                             |
+
+Every widget can be selected using a `kebab-case` class name matching its name. 
+You can also target popups by prefixing `popup-` to the name. For example, you can use `.clock` and `.popup-clock` respectively.
+
+Setting the `name` option on a widget allows you to target that specific instance using `#name`. 
+You can also add additional classes to re-use styles. In both cases, `popup-` is automatically prefixed to the popup (`#popup-name` or `.popup-my-class`).
+
+You can also target all GTK widgets of a certain type directly using their name. For example, `button:hover` will select the hover state on *all* buttons.
+These names are all lower case with no separator, so `MenuBar` -> `menubar`.
+
+GTK CSS does not support custom properties, but it does have its own custom `@define-color` syntax which you can use for re-using colours:
+
+```css
+@define-color color_bg #2d2d2d;
+
+box, menubar {
+    background-color: @color_bg;
+}
+```
