+# Release Process
+
+This document describes how to create a new release of the `react-native-leaflet-view` package.
+
+## Preparation
+
+1. Make sure all your changes are committed and pushed to the main branch.
+2. Pull the latest changes from the main branch:
+   ```
+   git checkout main
+   git pull origin main
+   ```
+
+3. Fix any linting issues:
+   ```
+   yarn lint --fix
+   ```
+
+## Release Process
+
+There are two ways to create a release:
+
+### Using release-it (automated way)
+
+1. Make sure you're logged in to npm:
+   ```
+   npm login
+   ```
+
+2. Run the release command:
+   ```
+   yarn release
+   ```
+   
+   This will:
+   - Prompt you for the new version (patch, minor, major)
+   - Update the version in package.json
+   - Create a git commit with the version change
+   - Create a git tag
+   - Push the changes and tag to GitHub
+   - Publish the package to npm
+   - Create a GitHub release
+
+3. If you want to specify the version type:
+   ```
+   yarn release patch   # For bug fixes (1.0.0 -> 1.0.1)
+   yarn release minor   # For new features (1.0.0 -> 1.1.0)
+   yarn release major   # For breaking changes (1.0.0 -> 2.0.0)
+   ```
+
+### Manual Release Process
+
+If you prefer more control over the process, follow these steps:
+
+1. Make sure you're logged in to npm:
+   ```
+   npm login
+   ```
+
+2. Update the version in package.json using npm (this also creates a git tag):
+   ```
+   npm version patch   # For bug fixes (1.0.0 -> 1.0.1)
+   npm version minor   # For new features (1.0.0 -> 1.1.0)
+   npm version major   # For breaking changes (1.0.0 -> 2.0.0)
+   ```
+
+   Or manually edit package.json and create a tag:
+   ```
+   # After editing package.json
+   git add package.json
+   git commit -m "chore: bump version to X.Y.Z"
+   git tag -a vX.Y.Z -m "Version X.Y.Z"
+   ```
+
+3. Push the changes and tags to GitHub:
+   ```
+   git push origin main --tags
+   ```
+
+4. Build and publish the package to npm:
+   ```
+   npm publish
+   ```
+
+5. Create a GitHub release (either through the GitHub web interface or using the GitHub CLI):
+   ```
+   gh release create vX.Y.Z --title "Version X.Y.Z" --notes "Release notes here"
+   ```
+
+## Troubleshooting
+
+### Version already exists on npm
+
+npm doesn't allow publishing the same version twice. If a version already exists, you'll need to increment to a new version.
+
+To check currently published versions:
+```
+npm view react-native-leaflet-view versions
+```
+
+### Linting issues
+
+If there are linting issues preventing the commit, fix them:
+```
+yarn lint --fix
+```
+
+Or for specific files:
+```
+yarn eslint "src/LeafletView/index.tsx" --fix
+```
+
+## Notes
+
+- Once a version is published to npm, it cannot be removed or republished with the same version number.
+- Make sure to update the README.md if there are significant changes in the new release.
+- Consider updating the example app to showcase new features.
