-**How to reproduce**
-
-- You must provide a way to reproduce the problem. If you are having an issue with your machine or build tools, the issue belongs on another repository as that is outside of the scope of React Navigation.
-- Either re-create the bug on [Snack](https://snack.expo.io) or link to a GitHub repository with code that reproduces the bug.
-- Explain how to run the example app and any steps that we need to take to reproduce the issue from the example app.
-- Keep the repro code as simple as possible, with the minimum amount of code required to repro the issue.
-- Before reporting an issue, make sure you are on latest version of the package.

 Maintainers with write access to the GitHub repo and the npm organization can publish new versions. To publish a new version, first, you need to export a `GH_TOKEN` environment variable as mentioned [here](https://github.com/lerna/lerna/tree/master/commands/version#--create-release-type). Then run:
 
 ```sh
-yarn lerna publish
+yarn release
 ```
 
 This will automatically bump the version and publish the packages. It'll also publish the changelogs on GitHub for each package.

-      <Title>What is Lorem Ipsum?</Title>
-      <Paragraph>
-        Lorem Ipsum is simply dummy text of the printing and typesetting
-        industry. Lorem Ipsum has been the industry&apos;s standard dummy text
-        ever since the 1500s, when an unknown printer took a galley of type and
-        scrambled it to make a type specimen book. It has survived not only five
-        centuries, but also the leap into electronic typesetting, remaining
-        essentially unchanged. It was popularised in the 1960s with the release
-        of Letraset sheets containing Lorem Ipsum passages, and more recently
-        with desktop publishing software like Aldus PageMaker including versions
-        of Lorem Ipsum.
-      </Paragraph>
-      <Title>Where does it come from?</Title>
-      <Paragraph>
-        Contrary to popular belief, Lorem Ipsum is not simply random text. It
-        has roots in a piece of classical Latin literature from 45 BC, making it
-        over 2000 years old. Richard McClintock, a Latin professor at
-        Hampden-Sydney College in Virginia, looked up one of the more obscure
-        Latin words, consectetur, from a Lorem Ipsum passage, and going through
-        the cites of the word in classical literature, discovered the
-        undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33
-        of &quot;de Finibus Bonorum et Malorum&quot; (The Extremes of Good and
-        Evil) by Cicero, written in 45 BC. This book is a treatise on the theory
-        of ethics, very popular during the Renaissance. The first line of Lorem
-        Ipsum, &quot;Lorem ipsum dolor sit amet..&quot;, comes from a line in
-        section 1.10.32.
-      </Paragraph>
-      <Paragraph>
-        The standard chunk of Lorem Ipsum used since the 1500s is reproduced
-        below for those interested. Sections 1.10.32 and 1.10.33 from &quot;de
-        Finibus Bonorum et Malorum&quot; by Cicero are also reproduced in their
-        exact original form, accompanied by English versions from the 1914
-        translation by H. Rackham.
-      </Paragraph>
-      <Title>Why do we use it?</Title>
-      <Paragraph>
-        It is a long established fact that a reader will be distracted by the
-        readable content of a page when looking at its layout. The point of
-        using Lorem Ipsum is that it has a more-or-less normal distribution of
-        letters, as opposed to using &quot;Content here, content here&quot;,
-        making it look like readable English. Many desktop publishing packages
-        and web page editors now use Lorem Ipsum as their default model text,
-        and a search for &quot;lorem ipsum&quot; will uncover many web sites
-        still in their infancy. Various versions have evolved over the years,
-        sometimes by accident, sometimes on purpose (injected humour and the
-        like).
-      </Paragraph>
-      <Title>Where can I get some?</Title>
-      <Paragraph>
-        There are many variations of passages of Lorem Ipsum available, but the
-        majority have suffered alteration in some form, by injected humour, or
-        randomised words which don&apos;t look even slightly believable. If you
-        are going to use a passage of Lorem Ipsum, you need to be sure there
-        isn&apos;t anything embarrassing hidden in the middle of text. All the
-        Lorem Ipsum generators on the Internet tend to repeat predefined chunks
-        as necessary, making this the first true generator on the Internet. It
-        uses a dictionary of over 200 Latin words, combined with a handful of
-        model sentence structures, to generate Lorem Ipsum which looks
-        reasonable. The generated Lorem Ipsum is therefore always free from
-        repetition, injected humour, or non-characteristic words etc.
