+# Contributing to Climbing Holds 3D Database
+
+Thank you for considering contributing to this community-driven dataset. Below are guidelines to keep the dataset consistent and easy to use with SetRsoft.
+
+## How to contribute
+
+- **Add new holds** — contribute 3D models and metadata for climbing holds.
+- **Improve existing entries** — fix metadata, update textures or models.
+- **Documentation** — improve the README or this file.
+
+## Adding a new hold
+
+### 1. Directory structure
+
+Create a folder named with the **hold ID** (e.g. `0000000002`) at the root of the dataset.
+
+Include:
+
+| File           | Description                          | Required |
+|----------------|--------------------------------------|----------|
+| `hold.glb`     | Web-ready 3D model                   | Yes      |
+| `hold.blend`   | Source file for Blender              | Yes      |
+| `texture.png`  | Texture image (PNG or JPG)           | Optional |
+| `metadata.json`| Hold specifications (see below)      | Yes      |
+
+### 2. Naming and IDs
+
+- Use a unique, zero-padded numeric ID for the folder (e.g. `0000000001`, `0000000002`).
+- Coordinate with maintainers if you need a new ID to avoid conflicts.
+
+### 3. metadata.json
+
+- Use **Unix timestamps** (seconds) for `created_at` and `last_update`.
+- Set **timezone_offset** (e.g. `"+01:00"`, `"UTC"`) so dates can be interpreted correctly.
+- Fill in as many fields as possible: `type`, `labels`, `color_of_scan`, `available_colors`, `manufacturer`, `model`, `size`, etc.
+
+Refer to the example in the [README](README.md#-structure).
+
+### 4. File formats
+
+- **GLB** — standard for web and SetRsoft; export from Blender with scale and orientation consistent with existing holds.
+- **Blend** — keep the source file so others can edit or re-export.
+- **Texture** — PNG or JPG; avoid unnecessary large resolutions.
+
+## Submitting changes
+
+1. **Fork** the repository and create a branch (e.g. `add-hold-0000000002`).
+2. **Add or modify** only the hold folder(s) and files you are contributing.
+3. **Open a Pull Request** with a short description of the hold(s) and, if applicable, source (scan, manufacturer, etc.).
+4. Maintainers will review structure, metadata, and file validity.
