+# Release Scripts
+
+This directory contains scripts to automate version bumping for SGLang releases.
+
+## Scripts
+
+### `bump_sglang_version.py`
+Updates SGLang version across all relevant files following the pattern from [PR #10468](https://github.com/sgl-project/sglang/pull/10468).
+
+**Usage:**
+```bash
+python scripts/release/bump_sglang_version.py 0.5.3rc0
+```
+
+**Files updated:**
+- `Makefile`
+- `benchmark/deepseek_v3/README.md`
+- `docker/Dockerfile.rocm`
+- `docs/get_started/install.md`
+- `docs/platforms/amd_gpu.md`
+- `docs/platforms/ascend_npu.md`
+- `python/pyproject.toml`
+- `python/pyproject_other.toml`
+- `python/sglang/version.py`
+
+### `bump_kernel_version.py`
+Updates sgl-kernel version across all relevant files following the pattern from [PR #10732](https://github.com/sgl-project/sglang/pull/10732).
+
+**Usage:**
+```bash
+python scripts/release/bump_kernel_version.py 0.3.12
+```
+
+**Files updated:**
+- `sgl-kernel/pyproject.toml`
+- `sgl-kernel/pyproject_cpu.toml`
+- `sgl-kernel/pyproject_rocm.toml`
+- `sgl-kernel/python/sgl_kernel/version.py`
+
+## Manual Testing Instructions
+
+### Test SGLang Version Bump
+
+1. **Run the script:**
+   ```bash
+   python scripts/release/bump_sglang_version.py 0.5.4rc0
+   ```
+
+2. **Verify changes with git diff:**
+   ```bash
+   git diff
+   ```
+
+3. **Check specific files contain the new version:**
+   ```bash
+   grep -r "0.5.4rc0" python/sglang/version.py
+   grep -r "0.5.4rc0" python/pyproject.toml
+   grep -r "0.5.4rc0" docs/get_started/install.md
+   ```
+
+4. **Reset changes (if testing):**
+   ```bash
+   git checkout .
+   ```
+
+### Test Kernel Version Bump
+
+1. **Run the script:**
+   ```bash
+   python scripts/release/bump_kernel_version.py 0.3.13
+   ```
+
+2. **Verify changes with git diff:**
+   ```bash
+   git diff
+   ```
+
+3. **Check specific files contain the new version:**
+   ```bash
+   grep -r "0.3.13" sgl-kernel/python/sgl_kernel/version.py
+   grep -r "0.3.13" sgl-kernel/pyproject.toml
+   ```
+
+4. **Reset changes (if testing):**
+   ```bash
+   git checkout .
+   ```
+
+## Version Format Validation
+
+- **SGLang versions:** `X.Y.Z` or `X.Y.ZrcN` (e.g., `0.5.3` or `0.5.3rc0`)
+- **Kernel versions:** `X.Y.Z` (e.g., `0.3.12`)
+
+The scripts will validate the version format and exit with an error if invalid.
