+
+# Bash & Tooling Instructions
+
+This document outlines the standard tools and commands used in this monorepo.
+
+## Package Manager
+
+We use **pnpm** for package management.
+- **Do not use `npm` or `yarn`.**
+- Lockfile: `pnpm-lock.yaml`
+- Workspace configuration: `pnpm-workspace.yaml`
+
+### Common Commands
+- Install dependencies: `pnpm install`
+- Run a script in a specific package: `pnpm --filter <package_name> run <script>`
+- Run a script in all packages: `pnpm -r run <script>`
+
+## Monorepo Tooling
+
+We use **Turbo** for build system orchestration.
+- Configuration: `turbo.json`
+
+## Project Structure
+
+- `apps/`: Contains application services (admin, api, live, proxy, space, web).
+- `packages/`: Contains shared packages and libraries.
+- `deployments/`: Deployment configurations.
+
+## Running Tests
+
+- To run tests in a specific package (e.g., codemods):
+  ```bash
+  cd packages/codemods
+  pnpm run test
+  ```
+- Or from root:
+  ```bash
+  pnpm --filter @plane/codemods run test
+  ```
+
+## Docker
+
+- Local development uses `docker-compose-local.yml`.
+- Production/Staging uses `docker-compose.yml`.
