-## Description
-
-[Nest](https://github.com/nestjs/nest) framework TypeScript starter repository.
-
-## Project setup
+# CodePapi Backend
 
-```bash
-$ pnpm install
-```
-
-## Compile and run the project
+## Overview
 
-```bash
-# development
-$ pnpm run start
-
-# watch mode
-$ pnpm run start:dev
+NestJS API server that orchestrates local LLM inference via Ollama and LangChain. Provides endpoints for code translation, review, and bug detection.
 
-# production mode
-$ pnpm run start:prod
-```
+**Note:** This is part of an experimental hobby project. Code quality and performance optimizations are secondary to learning and experimentation.
 
-## Run tests
+## Project Setup
 
 ```bash
-# unit tests
-$ pnpm run test
-
-# e2e tests
-$ pnpm run test:e2e
-
-# test coverage
-$ pnpm run test:cov
+npm install
 ```
 
-## Deployment
-
-When you're ready to deploy your NestJS application to production, there are some key steps you can take to ensure it runs as efficiently as possible. Check out the [deployment documentation](https://docs.nestjs.com/deployment) for more information.
-
-If you are looking for a cloud-based platform to deploy your NestJS application, check out [Mau](https://mau.nestjs.com), our official platform for deploying NestJS applications on AWS. Mau makes deployment straightforward and fast, requiring just a few simple steps:
+## Running the Application
 
 ```bash
-$ pnpm install -g @nestjs/mau
-$ mau deploy
+# Development mode
+npm run start:dev
+
+# Production mode
+npm run start
 ```
 
-With Mau, you can deploy your application in just a few clicks, allowing you to focus on building features rather than managing infrastructure.
+The API runs on `http://localhost:3000`

 ## Adding More Languages
 
-If you'd like to add new programming languages or framework migration presets to the UI, edit `frontend/src/constants/languages.ts`. The file exports two arrays: `LANGUAGES` (regular languages/options) and `MIGRATIONS` (framework-specific migration presets). Follow these guidelines:
+To add new programming languages to the UI, edit `frontend/src/constants/languages.ts`. The file exports a `LANGUAGES` array with supported languages.
 
 - File location: `frontend/src/constants/languages.ts`
-- Each language entry should include at least `id` and `name`.
-- Migration presets may include `id`, `name`, and any additional metadata your application uses.
+- Each language entry should include `id` and `name`
 
-Example entries:
+Example:
 
 ```ts

 ```
 
 Tips:
 
-- Keep `id` values unique and use kebab-case (e.g. `react-ts`, `node-express`).
-- If you add new migration presets, ensure the backend conversion logic (if any) recognizes the `id` and maps it to the proper prompt behavior.
-- After editing `languages.ts`, the `LanguageSelector` and other UI components will automatically include your new items.
-- You can add additional metadata (for example `editorMode`, `fileExtension`, or `isMigration`) if you want the UI or backend to handle the language differently — just update the consuming code accordingly.
+- Keep `id` values unique and use lowercase (e.g., `javascript`, `python`)
+- After editing `languages.ts`, the `LanguageSelector` component automatically includes your new items
+- The backend `converter.service.ts` handles the translation prompt for each language
 
-If you want help wiring up a more complex metadata format, tell me which fields you'd like and I can update the types and components for you.
+For more complex metadata or customization, check the component prop types in `LanguageSelector.tsx`.
