# Get Started


## Requirements

We will need to install python3.6 with sqlite3 support.
This can be done using the system package management, downloaded from [http://www.python.org](), or compiled from sources.

- Installing from the system package management:
    - OSX: `port install python36`
    - FreeBSD: `pkg install python36 py36-sqlite3`
    - Linux: `apt-get install ???`
- Installing from sources:
    - Download from [http://www.python.org]()
    - `unxz Python-3.6.tar.xz`
    - `tar xvf Python-3.6.tar`
    - `cd Python-3.6`
    - `./configure --prefix=$HOME/.local/bin`
    - `make && make install`

Next install pip (if not yet installed):

    python36 -m ensurepip --user

This will install pip in your account under `~/.local/bin`.
In the end you should be able to run `pip3 --version` and `python3 -c "import sqlite3"` without errors (sometimes `pip3` is `pip`, `pip3.6` or `pip-3.6`).

Install additional python packages locally on the user area:

    pip install --user tornado sqlalchemy pyyaml pygments markdown bcrypt networkx

These are usually installed under

- OSX: `~/Library/python/3.6/lib/python/site-packages/`
- Linux/FreeBSD: `~/.local/lib/python3.6/site-packages/`

Note: If you want to always install python modules on the user account, edit the pip configuration file `~/.config/pip/pip.conf` (FreeBSD, Linux) or `Library/Application Support/pip/pip.conf` (OSX) and add the lines

    [global]
    user = yes

## Installation

Replace USER by your bitbucket username:

    cd path/to/some/directory
    git clone https://USER@bitbucket.org/USER/aprendizations.git

A directory aprendizations will be created with the software:

    cd aprendizations

## Configuration

First we need to create a database:

    ./initdb.py                 # initialize with a single user `0`  and empty password
    ./initdb.py --help          # for the available options

We also need certificates for https. Generate selfsigned certificates using openssl:

    cd certs
    openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
    cd ..

Run a demonstration:

    ./serve.py
