+# workspace
+
+A multi-language test repository containing sample files for various languages and formats.
+
+## Prerequisites
+
+Ensure you have the following installed before getting started:
+
+- [Git](https://git-scm.com/) 2.x or later
+- [Python](https://www.python.org/downloads/) 3.8 or later (for `.py` files)
+- [Node.js](https://nodejs.org/) 18 or later and npm (for `.js` / `.ts` files)
+- [Rust](https://www.rust-lang.org/tools/install) 1.70 or later (for `.rs` files)
+
+## Setup
+
+### 1. Clone the repository
+
+```bash
+git clone <repository-url>
+cd workspace
+```
+
+### 2. Python
+
+No external dependencies are required for the Python sample files. If you add packages in the future, install them with:
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. Node.js / TypeScript
+
+If a `package.json` is present, install dependencies with:
+
+```bash
+npm install
+```
+
+To run a TypeScript file directly (requires `ts-node`):
+
+```bash
+npx ts-node test.ts
+```
+
+### 4. Rust
+
+Compile and run the Rust sample:
+
+```bash
+rustc test.rs -o test_bin
+./test_bin
+```
+
+### 5. Environment variables
+
+Copy the provided template and fill in the required values:
+
+```bash
+cp test.env .env
+```
+
+Edit `.env` with your local configuration before running any scripts.

+| `test.js` | JavaScript sample |
+| `test.ts` | TypeScript sample |
+| `test.rs` | Rust sample |
+| `test.yaml` | YAML configuration sample |
+| `test.json` | JSON data sample |
+| `test.xml.template` | XML template sample |

+
+## Batch changes
+
+The `hello-world.batch.yaml` and `hello-world2.batch.yaml` files are [Sourcegraph Batch Changes](https://docs.sourcegraph.com/batch_changes) specs. To run a batch change:
+
+1. Install the [Sourcegraph CLI (`src`)](https://docs.sourcegraph.com/cli)
+2. Authenticate: `src login`
+3. Preview the change: `src batch preview -f hello-world.batch.yaml`
+4. Apply the change: `src batch apply -f hello-world.batch.yaml`
+
+## Code ownership
+
+Ownership is defined in [`CODEOWNERS`](./CODEOWNERS). All files default to `@morgangauth`; Markdown files are additionally owned by `@test5`.
