  ## Customizations
  -### Disable the creation of Pull Requests
  -
  -The pull request feature can be disabled by options that are passed to the `CatalogImportPage`:
  -
  -```tsx
  -// packages/app/src/App.tsx
  -
  -<Route
  - path="/catalog-import"
  - element={<CatalogImportPage pullRequest={{ disable: true }} />}
  -/>
  +A custom layout can be passed to the import page, as it's already
  +supported by the search page. If no custom layout is passed, the default layout
  +is used.
  +
  +```typescript
  +<Route path="/catalog-import" element={<CatalogImportPage />}>
  + <Page themeId="home">
  + <Header title="Register an existing component" />
  + <Content>
  + <ContentHeader title="Start tracking your components">
  + <SupportButton>
  + Start tracking your component in Backstage by adding it to the
  + software catalog.
  + </SupportButton>
  + </ContentHeader>
  +
  + <Grid container spacing={2} direction="row-reverse">
  + <Grid item xs={12} md={4} lg={6} xl={8}>
  + Hello World
  + </Grid>
  +
  + <Grid item xs={12} md={8} lg={6} xl={4}>
  + <ImportStepper />
  + </Grid>
  + </Grid>
  + </Content>
  + </Page>
  +</Route>
  ```
  -### Customize the title and body of the Pull Request
  -
  -The pull request form is filled with a default title and body.
  -This can be configured by options that are passed to the `CatalogImportPage`:
  -
  -```tsx
  -// packages/app/src/App.tsx
  -
  -<Route
  - path="/catalog-import"
  - element={
  - <CatalogImportPage
  - pullRequest={{
  - preparePullRequest: () => ({
  - title: 'My title',
  - body: 'My **markdown** body',
  - }),
  - }}
  - />
  - }
  -/>
  -```
  +Previously it was possible to disable and customize the automatic pull request
  +feature by passing options to `<CatalogImportPage>` (`pullRequest.disable` and
  +`pullRequest.preparePullRequest`). This functionality is moved to the
  +`CatalogImportApi` which now provides an optional `preparePullRequest()`
  +function. The function can either be overridden to generate a different content
  +for the pull request, or removed to disable this feature.
