+Because of `<ForisForm />` component it's required to use exposed

+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:

+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
+```
