+# Worklenz Backend
+
+1. **Open your IDE:**
+
+   Open the project directory in your preferred code editor or IDE like Visual Studio Code.
+
+2. **Configure Environment Variables:**
+
+  - Create a copy of the `.env.template` file and name it `.env`.
+  - Update the required fields in `.env` with the specific information.
+
+3. **Restore Database**
+  - Create a new database named `worklenz_db` on your local PostgreSQL server.
+   - Update the `DATABASE_NAME` and `PASSWORD` in the  `database/6_user_permission.sql` with your DB credentials.
+  - Open a query console and execute the queries from the .sql files in the `database` directories, following the provided order.
+
+4. **Install Dependencies:**
+
+   ```bash
+   npm install
+   ```
+
+   This command installs all the necessary libraries required to run the project.
+
+5. **Run the Development Server:**
+
+   **a. Start the TypeScript compiler:**
+
+   Open a new terminal window and run the following command:
+
+      ```bash
+      grunt dev
+      ```
+
+   This starts the `grunt` task runner, which compiles TypeScript code into JavaScript.
+
+   **b. Start the development server:**
+
+   Open another separate terminal window and run the following command:
+
+      ```bash
+      npm start
+      ```
+
+   This starts the development server allowing you to work on the project.
+
+6. **Run the Production Server:**
+
+   **a. Compile TypeScript to JavaScript:**
+
+   Open a new terminal window and run the following command:
+
+      ```bash
+      grunt build
+      ```
+
+   This starts the `grunt` task runner, which compiles TypeScript code into JavaScript for production use.
+
+   **b. Start the production server:**
+
+   Once the compilation is complete, run the following command in the same terminal window:
+
+      ```bash
+      npm start
+      ```
+
+   This starts the production server for your application.
+
+### CLI
+
+- Create controller: `$ node new controller Test`
+- Create angular release: `$ node new release`
+
+### Developement Rules
+
+- Controllers should only generate/create using the CLI (`node new controller Projects`)
+- Validations should only be done using a middleware placed under src/validators/ and used inside the routers (E.g., api-router.ts)
+- Validators should only generate/create using the CLI (`node new vaidator projects-params`)
+
+## Pull submodules
+- git submodule update --init --recursive
