+
+## Map repositories and pull requests
+
+In the following example you will ingest your GitHub repositories, their README.md file contents and open pull requests to Port, you may use the following Port blueprint definitions and `port-app-config.yml`:
+
+<RepositoryBlueprint/>
+
+<PRBlueprint/>
+
+:::info repository type
+
+The `repositoryType` parameter filters which repositories are ingested. It corresponds to the `type` parameter in GitHub's [List organization repositories](https://docs.github.com/en/rest/repos/repos?apiVersion=2022-11-28#list-organization-repositories) API.
+
+<details>
+<summary>Possible values:</summary>
+
+*   `all` (default): All repositories accessible to the provided token.
+*   `public`: Public repositories.
+*   `private`: Private repositories.
+*   `forks`: Only forked repositories.
+*   `sources`: Only non-forked repositories.
+</details>
+
+:::
+
+<PortAppConfig/>
+
+:::tip learn more
+
+- We leverage [JQ JSON processor](https://stedolan.github.io/jq/manual/) to map and transform GitHub objects to Port Entities.
+- Click [Here](https://docs.github.com/en/rest/repos/repos#get-a-repository) for the GitHub repository object structure.
+- Click [Here](https://docs.github.com/en/rest/pulls/pulls#get-a-pull-request) for the GitHub pull request object structure.
+
+:::
+
+After creating the blueprints and committing the `port-app-config.yml` file to your `.github-private` repository (for global configuration), or to any specific repositories (for per-repo configuration), you will see new entities in Port matching your repositories alongside their README.md file contents and pull requests. (Remember that the `port-app-config.yml` file has to be in the **default branch** of the repository to take effect).
+
+## Map files and file contents
+
+The following example demonstrates ingestion of dependencies from a `package.json` file in your repository into Port: 
+
+<PackageBlueprint />
+<PackageAppConfig />
+
+The example will parse the `package.json` file in your repository and extract the dependencies into Port entities.  
+For more information about ingesting files and file contents, click [here](/build-your-software-catalog/sync-data-to-catalog/git/github-ocean/#ingest-files-from-your-repositories).
+
+
+
+## Map supported resources
+
+The examples above show specific use cases, but Port's GitHub integration supports the ingestion of many other GitHub objects.
+To adapt the examples above, use the GitHub API reference to learn about the available fields for the different supported objects:
+
+<GitHubResources/>
+
+When adding the ingestion of other resources, remember to add an entry to the `resources` array and change the value provided to the `kind` key accordingly.
