-# Library Notifications Service
-
-## System Requirements
-
-- pyenv
-- Python >=3.11
-- pre-commit
-- Poetry
-
-## Setup
-
-Before you start, ensure you have `pyenv` installed on your system. If not, you can install it using Homebrew (for macOS):
-
-```bash
-$ brew update
-$ brew install pyenv
-```
-
-For Linux, you can use the command below:
-
-```bash
-$ curl https://pyenv.run | bash
-```
-
-For Windows, please refer to the official [pyenv-win](https://github.com/pyenv-win/pyenv-win) repository.
-
-Once `pyenv` is installed, you can install Python 3.11:
-
-```bash
-$ pyenv install 3.11.0
-$ pyenv global 3.11.0
-```
-
-Next, install `pre-commit`:
-
-```bash
-$ pip install pre-commit
-```
-
-And finally, install `poetry`:
-
-```bash
-$ curl -sSL https://install.python-poetry.org | python -
-```
-
-## Installing the Project
-
-1. Clone the repository to your local machine:
-
-    ```bash
-    $ git clone https://github.com/cern-sis/Library-Notifications-Service.git
-    ```
-
-2. Navigate to the project directory:
-
-    ```bash
-    $ cd Library-Notifications-Service
-    ```
-
-3. Install the dependencies using `poetry`:
-
-    ```bash
-    $ poetry install
-    ```
-
-4. Install pre-commit hooks:
-    ```bash
-    $ pre-commit install
-    ```
-
-
-## Usage
-
-After installing, you can use the CLI as follows:
-
-### Newsletter
-
-```bash
-$ python -m src.cli newsletter
-```
-
-## Supported Arguments
-
-1. Subjects domain
-    - Get the latest(weekly) updates from backoffice and send the notifications for those present in the catalouge.
-    - Format: `value:scheme`
-
-2. Title
-    - Title of the notification
-    - Format: `'Information Technology'`
-
-3. Target Group
-    - Egroup identifier for sending targetted notifications.
-    - Format: `'library-newsletter-notif-it'`
-
-## Adding a new query to send notifications
-
-Add a new container with the required arguments (subject, title, target) in the below mentioned format in `cronjob.yml` in qa/prod environment.
-
-```yaml
--  name: <lns-subject>
-   image: registry.cern.ch/cern-sis/library-notifications-service
-   envFrom:
-    - secretRef:
-        name: lns-creds
-    - configMapRef:
-        name: lns-cfg
-    args:
-    - '--subjects'
-    - '<value:scheme>'
-    - '--title'
-    - '<string>'
-    - '--target'
-    - '<e-group-identifier>'
-```
-
-## Repository Structure
-
-1. api.py - Module containing calls to library catalouge, backoffice and notifications instances.
-2. cli.py - Main module conatining the supported command line arguments.
-3. utils.py - Module containing helper methods to manipulate data.
