 # pitiupi
-Este repositório tem 4 projetos Java que são independentes:
+Ferramenta p2p para práticas em rede
-### Sistema:
+Este repositório tem 3 projetos Java que são independentes:
 - A ferramenta pitiupi (P2P)
 ### Plugins: 
 - Um plugin de Chat
 - Um plugin de Chat multiprotocolo (TCP/UDP)
 - Um plugin de ScreenCast
 Cada um destes projetos deve ser compilado individualmente. Para isso, use a ferramenta ant no diretório do projeto.
@@ -24,26 +21,9 @@ Para criar links simbólicos no Linux, use o comando:
 ```
 cd pitiupi/plugins
 ln -s ../../pitiupi.chat/dist/*.jar .
 ln -s ../../pitiupi.mpChat/dist/*.jar .
 ln -s ../../pitiupi.screenCast/dist/*.jar .
 ``` 
 Isso deve resolver!
-## Como um plugin conversa com o pitiupi
+Para criar um novo plugin:
 Um plugin nunca recebe acesso direto às classes internas do núcleo (ConnectionManager, GuiManager). Em vez disso, recebe uma facade, a classe Pitiupi, que expõe só o que um plugin precisa: enviar mensagem (multicast, unicast ou tcp), abrir conexão tcp privada, ler nome de usuário e porta, criar menu.
 ```java
 public abstract void createPlugin(Pitiupi pitiupi);
 ```
 ## Para criar um novo plugin
 1. Implemente `pitiupi.models.Plugin`, incluindo `createPlugin(Pitiupi pitiupi)`
 2. Registre a classe em `src/META-INF/services/pitiupi.models.Plugin`, com o nome completo da classe numa linha
 3. Compile com `ant jar`
 4. Linke o `.jar` em `pitiupi/plugins`
 Use `pitiupi.chat` como referência — é o exemplo mais simples e completo.
 Plugins que ainda não foram atualizados para a Pitiupi (como uma versão mais antiga do screenCast) não compilam contra o núcleo atual e precisam de migração antes de serem usados.
