Here is a sample `README.md` file for your Django authentication package. This file includes instructions for installing the package, using it, and overriding components like the `User` model and views.

```markdown
# Django Accounts Package

A reusable Django authentication package providing customizable user authentication views and models.

## Installation

Install the package via pip:

```bash
pip install ns-django-custom-auth
```

## Basic Setup

After installation, add `accounts` to your `INSTALLED_APPS` in `settings.py`:

```python
INSTALLED_APPS = [
    ...
    'accounts',
    ...
]
```

Include the authentication URLs in your project's `urls.py`:

```python
from django.urls import path, include

urlpatterns = [
    path('api/auth/', include('accounts.urls')),
    ...
]
```

## Usage

### Importing Views and User Model

To use the default views and user model, you can import them as follows:

```python
from accounts import SignupApiView, LoginApiView, User
```

### Basic Usage Example

In your `urls.py`, you can include the views provided by the package:

```python
from django.urls import path
from accounts import SignupApiView, LoginApiView

urlpatterns = [
    path('signup/', SignupApiView.as_view(), name='signup'),
    path('login/', LoginApiView.as_view(), name='login'),
]
```

## Customizing the User Model

To use a custom user model, define it in your app and set `AUTH_USER_MODEL` in `settings.py`:

```python
# custom_app/models.py

from django.contrib.auth.models import AbstractUser
from django.db import models

class CustomUser(AbstractUser):
    mobile_no = models.CharField(max_length=15, unique=True)
    gender = models.CharField(max_length=10, null=True, blank=True)
```

In your `settings.py`:

```python
AUTH_USER_MODEL = 'custom_app.CustomUser'
```

## Overriding Signup and Login Views

To customize the `SignupApiView` and `LoginApiView`, subclass them and override methods as needed:

```python
# custom_app/views.py

from accounts.views import SignupApiView, LoginApiView
from .models import CustomUser
from .serializers import CustomUserSerializer

class CustomSignupApiView(SignupApiView):
    def post(self, request, *args, **kwargs):
        # Custom logic for user registration
        

class CustomLoginApiView(LoginApiView):
    def post(self, request, *args, **kwargs):
        # Custom logic for user login
        
```

In your `urls.py`:

```python
# custom_app/urls.py

from django.urls import path
from .views import CustomSignupApiView, CustomLoginApiView

urlpatterns = [
    path('signup/', CustomSignupApiView.as_view(), name='custom_signup'),
    path('login/', CustomLoginApiView.as_view(), name='custom_login'),
]
```
