+Set of utils and common React elements for reForis.
+
+## Publishing package
+
+### Beta versions
+
+Each commit to `dev` branch will result in publishing a new version of library
+tagged `beta`. Versions names are based on commit SHA, e.g.
+`foris@0.1.0-beta.d9073aa4`.
+
+### Preparing a release
+
+1. Crete a merge request to `dev` branch with version bumped
+2. When merging add `[skip ci]` to commit message to prevent publishing
+   unnecessary version
+3. Create a merge request from `dev` to `master` branch
+4. New version should be published automatically
+
+## Manually managed dependencies
+
+Because of `<ForisForm />` component it's required to use exposed
+`ReactRouterDOM` object from `react-router-dom` library. `ReactRouterDOM` is
+exposed by
+[reForis](https://gitlab.labs.nic.cz/turris/reforis/reforis/blob/master/js/webpack.config.js).
+It can be done by following steps:
+
+1. Setting `react-router-dom` as `peerDependencies` and `devDependencies` in
+   `package.json`.
+2. Adding the following rules to `externals` in `webpack.conf.js` of the plugin:
+
+```js
+externals: {
+    ...
+    "react-router-dom": "ReactRouterDOM",
+}
+```
+
+### Docs
+
+Build or watch docs to get more info about library:
+
+```bash
+make docs
+```
+
+or
+
+```bash
+make docs-watch
+```

+Sooner or later you will face with situation when you want/need to make some
+changes in the library. Then the most important tool for you it's
+[`npm link`](https://docs.npmjs.com/cli/link).
+
+Please, notice that it will not work if you link library just from root of the
+repo. It happens due to location of sources `./src`. You need to pack library
+first `make pack` and then link it from `./dist` directory.
+
+Yeah it's not such comfortable solution for development. But it can fixed by
+writing small script similar as `make pack` but with linking every file and
+directory from `./src` to the some directory and linking then from it. Notice
+that you need to link `package.json` and `package-lock.json` as well.
+
+So step by step:
+
+```bash
+make pack;
+cd dist;
+npm link;
+
+cd $project_dir/js # Navigate to JS directory of the project where you want to link the library
+npm link foris
+```
+
+And that's it ;)

+`<ForisForm/>` is Higher-Order Component which encapsulates entire form logic
+and provides with children required props. This component structure provides
+comfort API and allows to create typical Foris module forms easily.
+
+## Example of usage of `<ForisForm/>`
+
+You can pass more forms as children.
+
+```js
+<ForisForm
+    ws={ws}
+    forisConfig={{
+        endpoint: API_URLs.wan,
+        wsModule: "wan",
+    }}
+    prepData={prepData}
+    prepDataToSubmit={prepDataToSubmit}
+    validator={validator}
+>
+    <WANForm />
+    <WAN6Form />
+    <MACForm />
+</ForisForm>
+```
+
+### Example of children forms `props` usage
+
+```js
+export default function MACForm({
+    formData,
+    formErrors,
+    setFormValue,
+    ...props
+}) {
+    const macSettings = formData.mac_settings;
+    const errors = (formErrors || {}).mac_settings || {};
+    return (
+        <>
+            <h3>{_("MAC")}</h3>
+            <CheckBox
+                label={_("Custom MAC address")}
+                checked={macSettings.custom_mac_enabled}
+                helpText={HELP_TEXTS.custom_mac_enabled}
+                onChange={setFormValue((value) => ({
+                    mac_settings: { custom_mac_enabled: { $set: value } },
+                }))}
+                {...props}
+            />
+            {macSettings.custom_mac_enabled ? (
+                <TextInput
+                    label={_("MAC address")}
+                    value={macSettings.custom_mac || ""}
+                    helpText={HELP_TEXTS.custom_mac}
+                    error={errors.custom_mac}
+                    required
+                    onChange={setFormValue((value) => ({
+                        mac_settings: { custom_mac: { $set: value } },
+                    }))}
+                    {...props}
+                />
+            ) : null}
+        </>
+    );
+}
+```
+
+The <ForisForm/> passes subsequent `props` to the child components.
+
+| Prop           | Type   | Description                                                                |
+| -------------- | ------ | -------------------------------------------------------------------------- |
+| `formData`     | object | Data returned from API.                                                    |
+| `formErrors`   | object | Errors returned after validation via validator.                            |
+| `setFormValue` | func   | Function for data update. It takes update rule as arg (see example above). |
+| `disabled`     | bool   | Flag to disable form elements (during updates or loadings e.t.c.).         |
