-> To persist data you can mount volume at `/usr/app/data/`.
+- NocoDB needs a database as input : See [Production Setup](https://github.com/nocodb/nocodb/blob/master/README.md#production-setup).
+- If this input is absent, we fallback to SQLite. In order too persist sqlite, you can mount `/usr/app/data/`.

+
+  ```
+  docker run -d -p 8080:8080 --name nocodb -v /local/path:/usr/app/data/ nocodb/nocodb:latest

+# Por que estamos construindo isso?
 
 A maioria das empresas da Internet equipar-se com a planilha ou um banco de dados para resolver suas necessidades de negócios. Planilhas são usadas por um bilhão de seres humanos colaborativamente todos os dias. No entanto, estamos longe de trabalhar em velocidades semelhantes em bancos de dados que são muito mais poderosas ferramentas quando se trata de computação. As tentativas de resolver isso com ofertas de SaaS significam controles de acesso horríveis, lockin do fornecedor, lockin de dados, alterações abruptas de preços e mais importante, um teto de vidro no futuro.

 Nossa missão é fornecer a mais poderosa interface de código para bancos de dados que é fonte aberta para cada negócio de Internet no mundo. Isso não apenas democratizaria o acesso a uma poderosa ferramenta de computação, mas também produzirá um bilhão de pessoas que terão habilidades radicais de corda e construção na Internet."
