-This README would normally document whatever steps are necessary to get the
-application up and running.
+Colector de datos.
 
-Things you may want to cover:
+## Configuración
 
-* Ruby version
+1. Conseguir la _master key_ desde otrx miembrx del proyecto y colocarla
+   en `config/master.key`.
 
-* System dependencies
+   * Si no sos parte del proyecto, podés borrar el archivo
+     `config/credentials.yml.enc` y recrearlo con:
 
-* Configuration
+     ```bash
+     rm config/credentials.yml.enc
+     make rails args=credentials:edit
+     ```
 
-* Database creation
+     Dentro hay que agregar las variables siguientes con contraseñas de
+     128 caracteres, que se pueden generar con `pwgen -1 128`.
 
-* Database initialization
+     ```yaml
+     secret_key_base: "contraseña de 128 caracteres"
+     devise_pepper: "contraseña de 128 caracteres"
+     ```
 
-* How to run the test suite
-
-* Services (job queues, cache servers, search engines, etc.)
-
-* Deployment instructions
-
-* ...
+2. Adaptar las variables en el archivo `ansible.yml`.
