+:::
+
+Personio is a human resources management software that helps businesses streamline HR processes,
+including recruitment, employee data management, and payroll, in one platform.
+
+Our [Personio verified](https://github.com/dlt-hub/verified-sources/blob/master/sources/personio) source loads data using Perosnio API to your preferred
+[destination](../destinations).
+
+:::tip
+You can check out our pipeline example [here](https://github.com/dlt-hub/verified-sources/blob/master/sources/personio_pipeline.py).
+:::
+
+Resources that can be loaded using this verified source are:
+
+| Name        | Description                                                                              |
+|-------------|------------------------------------------------------------------------------------------|
+| employees   | Retrieves company employees details. (Employees list, absense_entitlement, cost_centers) |
+| absences    | Retrieves list of various types of employee absences                                     |
+| attendances | Retrieves attendance records for each employee                                           |
+
+## Setup Guide
+
+### Grab credentials
+
+To load data from Personio, you need to obtain API credentials, `client_id` and `client_secret`:
+
+1. Sign in to your Personio account, and ensure that your user account has API access rights.
+1. Navigate to Settings > Integrations > API credentials.
+1. Click on "Generate new credentials."
+1. Assign necessary permissions to credentials, i.e. read access.
+
+:::info
+The Personio UI, which is described here, might change. The full guide is available at this [link.](https://developer.personio.de/docs#21-employee-attendance-and-absence-endpoints)
+:::
+
+### Initialize the verified source
+
+To get started with your data pipeline, follow these steps:
+
+1. Enter the following command:
+
+   ```bash
+   dlt init personio duckdb
+   ```
+
+   [This command](../../reference/command-line-interface) will initialize
+   [the pipeline example](https://github.com/dlt-hub/verified-sources/blob/master/sources/personio_pipeline.py)
+   with Personio as the [source](../../general-usage/source) and [duckdb](../destinations/duckdb.md)
+   as the [destination](../destinations).
+
+1. If you'd like to use a different destination, simply replace `duckdb` with the name of your
+   preferred [destination](../destinations).
+
+1. After running this command, a new directory will be created with the necessary files and
+   configuration settings to get started.
+
+For more information, read [Add a verified source.](../../walkthroughs/add-a-verified-source)
+
+### Add credentials
+
+1. In the `.dlt` folder, there's a file called `secrets.toml`. It's where you store sensitive
+   information securely, like access tokens. Keep this file safe. Here's its format for service
+   account authentication:
+
+   ```toml
+   # Put your secret values and credentials here
+   # Note: Do not share this file and do not push it to GitHub!
+   [sources.personio]
+   client_id = "papi-*****" # please set me up!
+   client_secret = "papi-*****" # please set me up!
+   ```
+
+1. Replace the value of `client_id` and `client_secret` with the one that
+   [you copied above](#grab-credentials). This will ensure that your data-verified source can access
+   your Personio API resources securely.
+
+1. Next, follow the instructions in [Destinations](../destinations/duckdb) to add credentials for
+   your chosen destination. This will ensure that your data is properly routed to its final
+   destination.
+
+For more information, read [Credentials](../../general-usage/credentials).
+
+## Run the pipeline
+
+1. Before running the pipeline, ensure that you have installed all the necessary dependencies by
+   running the command:
+   ```bash
+   pip install -r requirements.txt
+   ```
+1. You're now ready to run the pipeline! To get started, run the following command:
+   ```bash
+   python personio_pipeline.py
+   ```
+1. Once the pipeline has finished running, you can verify that everything loaded correctly by using
+   the following command:
+   ```bash
+   dlt pipeline <pipeline_name> show
+   ```
+   For example, the `pipeline_name` for the above pipeline example is `personio`, you may also use
+   any custom name instead.
+
+For more information, read [Run a pipeline.](../../walkthroughs/run-a-pipeline)
+
+## Sources and resources
+
+`dlt` works on the principle of [sources](../../general-usage/source) and
+[resources](../../general-usage/resource).
+
+### Source `personio_source`
+
+This `dlt` source returns data resources like "employees", "absences", and "attendances".
+
+```python
+@dlt.source(name="personio")
+def personio_source(
+    client_id: str = dlt.secrets.value,
+    client_secret: str = dlt.secrets.value,
+    items_per_page: int = DEFAULT_ITEMS_PER_PAGE,
+) -> Iterable[DltResource]:
+```
+
+`client_id`: Generated ID for API access.
+
+`client_secret`: Generated secret for API access.
+
+`items_per_page`: Maximum number of items per page, defaults to 200.
+
+### Resource `employees`
+
+This resource retrieves data on all the employees in a company.
+
+```python
+ @dlt.resource(primary_key="id", write_disposition="merge")
+def employees(
+    updated_at: dlt.sources.incremental[
+        pendulum.DateTime
+    ] = dlt.sources.incremental(
+        "last_modified_at", initial_value=None, allow_external_schedulers=True
+    ),
+    items_per_page: int = items_per_page,
+) -> Iterable[TDataItem]:
+```
+
+`updated_at`: The saved state of the last 'last_modified_at' value. It is used for
+[incremental loading](../../general-usage/incremental-loading).
+
+`items_per_page`: Maximum number of items per page, defaults to 200.
+
+Like the `employees` resource discussed above, other resources `absences` and `attendances` load
+data from the Personio API to your preferred destination.
+
+## Customization
+
+### Create your own pipeline
+
+If you wish to create your own pipelines, you can leverage source and resource methods from this
+verified source.
+
+1. Configure the [pipeline](../../general-usage/pipeline) by specifying the pipeline name, destination, and dataset as follows:
+
+   ```python
+   pipeline = dlt.pipeline(
+      pipeline_name="personio",  # Use a custom name if desired
+      destination="duckdb",  # Choose the appropriate destination (e.g., duckdb, redshift, post)
+      dataset_name="personio_data"  # Use a custom name if desired
+   )
+   ```
+
+1. To load employee data:
+
+   ```python
+   load_data = personio_source().with_resources("employees")
+   print(pipeline.run(load_data))
+   ```
+
+1. To load data from all supported endpoints:
+
+   ```python
+   load_data = personio_source()
+   print(pipeline.run(load_data))
+   ```
