 ### Release procedure
 1. Make sure `changelog.txt` is up-to-date. Use a new version number and copy over the new section into `readme.txt`.
 2. Update `package.json` with the same version number.
-3. Build: `npm run build-prod`
-4. Determine minimum PHP version for code and update package.json if needed: `./vendor/bin/phpcompatinfo analyser:run ./source`
-5. Make sure screenshots are up-to-date.
-6. Copy the built plugin into `/trunk` of SVN. Also creatte a new tag of the new version. Check the version number occurences in both folders. Commit everything together.
+3. Update the `package-lock.json`: `npm i --package-lock-only`
+4. Build: `npm run build-prod`
+5. Determine minimum PHP version for code and update package.json if needed: `./vendor/bin/phpcompatinfo analyser:run ./source`
+6. Make sure screenshots are up-to-date.
+7. Copy the built plugin into `/trunk` of SVN.
+8. Create a new tag of the new version: `svn cp trunk tags/<version>`
+9. Check the version number occurences in both folders.
+10. Commit everything together to the release SVN: `svn ci -m "release version <version>"`
+11. Commit and tag the new version in `git` too.
 
 ### Other commands
+- Run ESLint: `npm run eslint`
+- Run JavaScript code coverage with tests: `npm run coverage`
 - Run tests: `npm test`
 - Delete build folder: `gulp clean`
