+# Release Command
+
+Create a new version tag and optionally push it to the remote.
+
+## Arguments
+- `major` - Increment major version (e.g., v0.1.1 -> v1.0.0)
+- `minor` - Increment minor version (e.g., v0.1.1 -> v0.2.0)
+- (default) - Increment patch version (e.g., v0.1.1 -> v0.1.2)
+- `--push` - Push the tag to remote after creating
+
+## Instructions
+
+1. Get the latest version tag:
+   ```bash
+   git tag -l 'v*' --sort=-v:refname | head -1
+   ```
+
+2. If no tags exist, start with v0.1.0 as the base (next will be v0.1.1)
+
+3. Parse the version and increment based on the argument:
+   - Extract major, minor, patch from the tag (e.g., v1.2.3 -> 1, 2, 3)
+   - If argument is `major`: increment major, reset minor and patch to 0
+   - If argument is `minor`: increment minor, reset patch to 0
+   - Otherwise (default): increment patch
+
+4. Create the new tag:
+   ```bash
+   git tag -a v{VERSION} -m "Release v{VERSION}"
+   ```
+
+5. Show the created tag and recent commits since the last tag
+
+6. If `--push` was specified, push the tag:
+   ```bash
+   git push origin v{VERSION}
+   ```
+
+7. Display the new version and instructions for pushing if not auto-pushed
