-
-## Native
-
-To a certain extent, the frontend and backend can be developed independently. The frontend is a Vue.js project and the
-backend is a DRF (Django-Rest-Framework) project. If you want to develop the frontend, you can do so without the backend
-and vice
-versa. However, especially for the frontend, it is recommended to use the backend as well, as the frontend does not have
-a lot of 'offline' functionality.
-If you want to run the fullstack application, it is recommended to use the [docker-compose](#docker) method.
-
-### Frontend
-
-install `node.js` and `npm`
-
-on Debian* for example: `sudo apt install npm`
-
-``` bash
-cd toolshed/frontend
-npm install
-npm run dev
-```
-
-### Backend
-
-Install `python3`, `pip` and `virtualenv`
-
-on Debian* for example: `sudo apt install python3 python3-pip python3-venv`
-
-Prepare backend environment
-
-``` bash
-cd toolshed/backend
-python -m venv venv
-source venv/bin/activate
-pip install -r requirements.txt
-```
-
-Run the test suite:
-
-``` bash
-python manage.py test
-```
-
-optionally with coverage:
-
-``` bash
-coverage run manage.py test
-coverage report
-```
-
-Start the backend in development mode:
-
-``` bash
-python manage.py migrate
-cp .env.dist .env
-echo "DEBUG = True" >> .env
-python manage.py runserver 0.0.0.0:8000
-```
-
-provides the api docs at `http://localhost:8000/docs/`
-
-### Docs (Wiki)
-
-Install `mkdocs`
-
-on Debian* for example: `sudo apt install mkdocs`
-
-Start the docs server:
-
-``` bash
-cd toolshed/docs
-mkdocs serve -a 0.0.0.0:8080
-```
-
-## Docker
-
-### Fullstack
-
-Install `docker` and `docker-compose`
-
-on Debian* for example: `sudo apt install docker.io docker-compose`
-
-Start the fullstack application:
-
-``` bash
-docker-compose -f deploy/docker-compose.override.yml up --build
-```
-
-This will start an instance of the frontend and wiki, a limited DoH (DNS over HTTPS) server and **two** instances of the backend.
-The two backend instances are set up to use the domains `a.localhost` and `b.localhost`, the local DoH
-server is used to direct the frontend to the correct backend instance.
-The frontend is configured to act as if it was served from the domain `a.localhost`.
-Access the frontend at `http://localhost:8080/`, backend at `http://localhost:8080/api/`, api docs
-at `http://localhost:8080/docs/` and the wiki at `http://localhost:8080/wiki/`.

-# Federation
-
-This section will cover how federation works in Toolshed.
-
-## What is Federation?
-
-Since user of Toolshed you can search and interact the inventory of all their 'friends' that are potentially on
-different servers there is a need for a way to communicate between servers. We don't want to rely on a central server that
-stores all the data and we don't want to have a central server that handles all the communication between servers. This
-is where federation comes in. Toolshed uses a protocol that can not only exchange data with the server where the user
-is registered but also with the servers where their friends are registered.
-
-## How does it work?
-
-Any user can register on any server and creates a personal key pair. The public key is stored on the server and the private
-key is stored on the client. The private key is used to sign all requests to the server and the public key is used to
-verify the signature. Once a user has registered on a server they can send friend requests to other users containing
-their public key. If the other user accepts the friend request, the server stores the public key of the friend and
-uses it to verify access to the friend's inventory. While accepting a friend request the user also automatically sends
-their own public key to the friend's server. This way both users can access each other's inventory.
-
-The protocol is based on a simple HTTPS API exchanging JSON data that is signed with the user's private key. By default
-Toolshed servers provide a documentation of the API at [/docs/api](/docs/api).
