+# CLI
+
+_Symb_ has a separate package to it's CLI, so the core package can be more lightweight and encapsulated.
+
+The CLI is very useful to generate migrations and entities automatically.
+
+## Installation
+
+Migrations are created or generated using the `@techmmunity/symbiosis-cli` package, so first of all, we need to install the package.
+
+```sh
+yarn add -D @techmmunity/symbiosis-cli
+```
+
+## Preparation
+
+Add a alias to the `symb` command.
+
+```json
+// package.json
+
+{
+  //...
+  "scripts": {
+    //...
+    "symb": "symb"
+  }
+}
+```
+
+Create a `symbiosis.config.js` file in the root dir of your app, or generate one using the [`gen:config`](#genconfig) command.
+
+```js
+module.exports = {
+  migrationsDir: "migrations/dir",
+  entitiesDir: ["entities/**/dir/*.ts"],
+  databaseConfig: {
+    // ...
+  },
+};
+```
+
+## Commands
+
+### `gen:config`
+
+Automatically generates a config file at the root dir of your app.
+
+The options of `symbiosis.config.js` are the same of the [`Connection`](./connections#options) class.
+
+```sh
+yarn symb gen:config
+```
+
+### `gen:migration`
+
+This command will generate all migrations to update you database according to your code.
+
+To use this command, you need to create a `symbiosis.config.js` file. You you don't have one, you can generate a empty one using the [`gen:config`](#genconfig) command.
+
+```sh
+yarn symb gen:migration
+```
+
+### `create:migration`
+
+Create an empty migration, so you can write the migration by your own.
+
+```sh
+yarn symb create:migration
+```
