 * Q: I have a _huge_ amount of DB events per second in my app, can I disable the deep-equality check in `db` effect handler?  
   A: Specify `eq` in [`rf._init`](docs/re-frame.md#_init-opts) to replace it with either [`eqShallow`](docs/util.md#eqShallow-a-b)
   or [`indentical`](docs/util.md#identical-a-b).
+* Q: I hate commas and languages that aren't syntactical supersets of JS. Can I still use this somehow?  
+  A: Well if you _absolutely must_, you can [use JSX](docs/jsx-runtime.md). (Note that JSX is not exatly a great match for Reagent components.)

+There's also [`jsx-runtime`](docs/jsx-runtime.md) which isn't included in main module (it implements JSX support).

 Each of these can be used separately (`require('mreframe/<name>')`), or as part of the main module
 (`require('mreframe').<name>`; `.reFrame` in case of `re-frame` module). Note that the nodeps bundle doesn't load
 Mithril libraries by default (so you'll have to call the `_init` function which it also exports).

+## `jsx-runtime` module
+
+Implements a JSX interface for [Babel API](https://babeljs.io/docs/babel-plugin-transform-react-jsx).  
+You're likely not going to use this directly.
+
+Exports the following items:
+* `jsx (tag, {children?, ...attrs}, key?)` – a replacement for single-child (or childless) JSX element
+* `jsxs (tag, {children=[], ...attrs}, key?)` – a replacement for multi-child JSX element
+* `Fragment` – the `tag` value for `<>` tags (equals to `'<>'`, as per Hiccup definition)
+
+
+### Usage
+
+In order to use `mreframe` with JSX, you need to do the following:
+* install NPM packages `@babel/cli`, `@babel/core`, `@babel/plugin-transform-react-jsx`;
+  optionally `@babel/plugin-transform-modules-commonjs` (to use produced files directly in browser)
+* configure Babel (i.e. in `.babelrc`):
+  ```js
+  {
+    "plugins": [
+      ["@babel/plugin-transform-react-jsx", {
+        "runtime":      "automatic",
+        "importSource": "mreframe"
+      }],
+      // uncomment this to have require() instead of import; this makes JSX output messier though
+      //["@babel/plugin-transform-modules-commonjs"]
+    ]
+  }
+  ```
+* add a `script` command (in `package.json`) to run Babel; e.g.
+  ```json
+  {
+    ...
+    "script": {
+      "build": "babel src/ -d dist/"
+    }
+    ...
+  }
+  ```
+  such a command can be run as `npm run build` (or `yarn build` when using `yarn`)
+
+
+### Issues
+
+JSX is not particularly compatible with Reagent-style components; you're likely to encounter following issues:
+
+* component arguments have to be passed as `children` array; this may take one of the following forms:
+  - `<Component>{[foo, bar, baz]}</Component>`
+  - `<Component>{foo}{bar}{baz}</Component}`
+  - `<Component children={[foo, bar, baz]}/>`
+  - `{[Component, foo, bar, baz]}`
+
+* single arguments can be passed without wrapping into an array… unless it's an array value: in this case not
+  wrapping it would result in it being treated as an argument list
+
+* attributes can be used, but they're _not_ included in the component arguments; they're passed as `meta`/`attrs`
+  (i.e. `r.props( r.currentComponent() )`)
+
+* native (Mithril) components must be [adapted](reagent.md#adaptComponent-c) before you can use them
+
+* attributes named `children` or `argv` are unsupported
