+# Software Público - configuration management
+
+## Requirements
+
+* [chake](https://rubygems.org/gems/chake)
+* rake
+
+For development
+
+* vagrant
+* shunit2
+* moreutils
+* redir
+
+## Configuration parameters
+
+All configuration parameters are defined in `nodes.yaml`, with exception of IP
+addresses, which are defined in different files:
+
+- for local development, the IP addresses of the Vagrant VMs are defined in
+  config/local/ips.yaml.
+
+- for production, you need to create a new file called
+  `config/production/ips.yaml`
+
+You will probably not need to change nodes.yaml unless you are developing the
+deployment process.
+
+## Deploy
+
+### Development
+
+First you have to bring up the development virtual machines:
+
+```bash
+$ vagrant up
+$ rake preconfig
+$ rake bootstrap_common
+```
+
+Right now there are 5 VM's, so this might take a while. The basic commands for
+deployment:
+
+```bash
+$ rake                                  # deploys all servers
+$ rake nodes                            # lists all servers
+$ rake converge:$server                 # deploys only $server
+```
+
+### Production
+
+* TODO: document adding the SSL key and certificate
+* TODO: document creation of `prod.yaml`.
+* TODO: document SSH configuration
+
+The very first step is
+
+```
+$ rake preconfig SPB_ENV=production
+```
+
+This will perform some initial configuration to the system that is required
+before doing the actual deployment.
+
+After that:
+
+```bash
+$ rake SPB_ENV=production                   # deploys all servers
+$ rake nodes SPB_ENV=production             # lists all servers
+$ rake converge:$server SPB_ENV=production  # deploys only $server
+```
+
+You can also do `export SPB_ENV=production` in your shell and omit it in the
+`rake` calls.
+
+See the output of `rake -T` for other tasks.
+
+## Viewing the running site when developping locally
+
+Run:
+
+```bash
+./server
+```
+
+Follow the on-screen instructions an browse to
+[http://softwarepublico.dev/](http://softwarepublico.dev/).
+
+Note: this requires that your system will resolve `\*.dev` to `localhost`.
+Google DNS servers will do that automatically, otherwise you might add the following entries to `/etc/hosts`:
+
+```
+127.0.53.53 softwarepublico.dev
+127.0.53.53 listas.softwarepublico.dev

-## Requirements
+## Organização
 
-* [chake](https://rubygems.org/gems/chake)
-* rake
+Este repositório contém tanto o código fonte desenvolvimento especificamente
+para o SPB, quando o código de gestão de configuração necessário para implantar
+o ambiente do SPB.
 
-For development
+O código fonte dos componentes e pacotes desenvolvidos está no diretório
+`src/`.  Os demais diretórios contém código de gestão de configuração,
+documentação, utilitários etc.
 
-* vagrant
-* shunit2
-* moreutils
-* redir
+## Fazendo um release
 
-## Configuration parameters
+* Atualize o número de versão no arquivo VERSION
+* Execute `make release`.
 
-All configuration parameters are defined in `nodes.yaml`, with exception of IP
-addresses, which are defined in different files:
-
-- for local development, the IP addresses of the Vagrant VMs are defined in
-  config/local/ips.yaml.
