+
+      "Derivative Works" shall mean any work, whether in Source or Object

+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# IDA recruitment test
+
+IDA (**I**n**D**ex re**A**der) is an API for providing data from the well-known share indices ([DAX](https://en.wikipedia.org/wiki/DAX) & [S&P](https://en.wikipedia.org/wiki/S%26P_Global_Ratings)). It is intended to represent an exemplary application that exists within [Union Investment](https://www.union-investment.de/startseite) and is designed to test the basic programming skills of applicants.
+
+Technically, [Python 3](https://www.python.org/) and [FastAPI](https://fastapi.tiangolo.com/) are used for the API. Both technologies allow fast and stable web service development.

+- [Preparation](#preparation)
+- [Exercises](#exercises)
+	- [Excercise 1](#excercise-1)
+	- [Excercise 2](#excercise-2)
+	- [Excercise 3](#excercise-3)
+
+## Preparation
+
+Before you start, you must:
+
+- Install [Python 3.6.x.](https://www.python.org/downloads/)
+- Install [Pipenv](https://pipenv.pypa.io/en/latest/#install-pipenv-today)
+
+To activate this project's virtualenv, run following command:
+
+```python
+pipenv shell
+```
+
+Then install the project dependencies with:
+
+```python
+pipenv install
+```
+
+After successful installation the API can be started locally with the command:
+
+```python
+uvicorn main:app --reload
+```
+
+You will now be able of accessing the API via your browser on [http://127.0.0.1:8000](http://127.0.0.1:8000).
+
+## Exercises
+
+Please complete the exercises within one week and submit the results as previously agreed.We will discuss the task together in a subsequent interview. All tasks can be solved with the help of the [documentation](https://fastapi.tiangolo.com/).
+
+If you have direct questions about the Recrutiment Test, you can contact us directly via e-mail at [cloudoperations@union-investment.de](mailto:cloudoperations@union-investment.de).
+
+**Good luck with the exercises!**
+
+### Excercise 1
+
+Extend the API with another endpoint that should be accessible via the `/getdata` path. This endpoint is to return all share indices in a list page by page. Each page should contain a maximum of 30 elements.
+
+### Excercise 2
+
+Please complete the `create_upload_files` method so that you can update share indices data at runtime. The data should be sent in the form of a CSV file using an HTTP POST request.
+
+For example, the following curl command can be used for testing:
+
+```bash
+curl -d @daxsp.csv http://127.0.0.1:8000/uploadfile
+```
+
+[Note in the documentation](https://fastapi.tiangolo.com/tutorial/request-files/)
+
+### Excercise 3
+
+Finally, please write appropriate unit tests for your two tasks using the [components provided by FastAPI](https://fastapi.tiangolo.com/tutorial/testing/).
+To do this, expand the test_main.py file. The tests can be run with the following command:
+
+```python
+pytest
+```
