-# INSTALACIÓN:
+# Device Hub
 
-La instalación es muy estándar
+DeviceHub is an IT Asset Management System focused on reusing devices, created under the [eReuse.org](https://www.ereuse.org) project.
 
+## Overview
+
+DeviceHub aims to:
+
+- Provide a common IT Asset Management platform for donors, receivers, and IT professionals.
+- Automatically collect, analyze, and share device metadata while ensuring privacy and traceability.
+- Integrate with existing IT Asset Management Systems.
+- Operate in a decentralized manner.
+
+DeviceHub primarily works with three types of objects:
+
+1. **Devices**: Including computers, smartphones, and their components.
+2. **Events**: Actions performed on devices (e.g., Repair, Allocate).
+3. **Accounts**: Users who perform events on devices.
+
+## Installation
+
+Assuming a host with debian stable
+
+### Quickstart
+
+For a quick start with dummy data in localhost, DeviceHub can be run directly with docker. To do so, from the root of the project run:
+
+```bash
+./docker-reset.sh
 ```
+
+Note that everytime you perform the `docker-reset.sh` script, all data is lost.
+
+Also there is a demo running in http://demo.ereuse.org/. The token for accessing the instance will be always: `token=5018dd65-9abd-4a62-8896-80f34ac66150`, but the instance will be reset every day at 4 am.
+
+For production needs, review and change .env file properly
+
+## Running from baremetal
+
+### Prerequisites
+
+- Python 3.10
+- pip
+- virtualenv
+
+Specially when developing, is quite convenient to run DeviceHub from a virtual environment. To start with this deployment, create a virtual environment to isolate our project dependencies:
+
+```bash
 python -m venv env
-source env/bin/actevate
-python install -r requirements.txt
+source env/bin/activate
+pip install -r requirements.txt
 ```
 
-## IMPORTANT EXTERNAL DEPENDENCIES
+### System Dependencies
 
-Para arrancarlo es necesario tener el paquete `xapian-bindings` en tu ordenador. No se instala mediante `pip`, así que depende de cada [sistema operativo](https://xapian.org/download).
+#### Xapian
 
-Luego solo necesitas:
+Now, install the xapian dependencies (xapian library and python bindings)
 
+```bash
+sudo apt-get install python3-xapian libxapian-dev
 ```
-./manage.py migrate
-./manage.py runserver
+
+Allow the virtual environment to use system-installed packages:
+
+```bash
+export PYTHONPATH="${PYTHONPATH}:/usr/lib/python3/dist-packages"
 ```
+
+#### Environment Variables
+
+Now, configure the environment variables. For this, we will expand a `.env` file. You can use the following content as an example:
+
+```source
+STATIC_ROOT=/tmp/static/
+MEDIA_ROOT=/tmp/media/
+ALLOWED_HOSTS=localhost,localhost:8000,127.0.0.1,
+DOMAIN=localhost
+DEBUG=True
+```
+
+Now, expand the environment variables:
+
+```bash
+source .env
+```
+
+### Migrations
+
+Now, apply migrations
+
+```bash
+python manage.py makemigrations
+python manage.py migrate
+```
+
+Also, we can add some dummy data into the database to play along:
+
+```bash
+python manage.py add_institution Pangea
+python manage.py add_user Pangea user@example.org 1234
+python manage.py up_snapshots example/snapshots/ user@example.org
+```
+
+### Run DeviceHub
+
+Finally, we can run the DeviceHub service by running:
+
+```bash
+python manage.py runserver
+```
+
+### Clean up
+
+To clean up the deployment and start fresh, just delete Django's database:
+
+```bash
+rm db/*
+```
+
