+# Developer's Guide
+
+We use Visual Studio Code for developing LoopBack and recommend the same to our
+users.
+
+## VSCode setup
+
+Install the following extensions:
+
+ - [eslint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint)
+ - [prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode)
+
+## Development workflow
+
+### Visual Studio Code
+
+1. Start the build task (Cmd+Shift+B) to run TypeScript compiler in the
+   background, watching and recompiling files as you change them. Compilation
+   errors will be shown in the VSCode's "PROBLEMS" window.
+
+2. Execute "Run Rest Task" from the Command Palette (Cmd+Shift+P) to re-run the
+   test suite and lint the code for both programming and style errors. Linting
+   errors will be shown in VSCode's "PROBLEMS" window. Failed tests are printed
+   to terminal output only.
+
+### Other editors/IDEs
+
+1. Open a new terminal window/tab and start the continuous build process via
+   `npm run build:watch`. It will run TypeScript compiler in watch mode,
+   recompiling files as you change them. Any compilation errors will be printed
+   to the terminal.
+
+2. In your main terminal window/tab, run `npm run test:dev` to re-run the test
+   suite and lint the code for both programming and style errors. You should run
+   this command manually whenever you have new changes to test. Test failures
+   and linter errors will be printed to the terminal.
