+# Releasing
+
+This guide explains how to release a new version of the uptrace-ruby gem to
+RubyGems.
+
+## Managing Dependencies
+
+### Checking for outdated dependencies
+
+To view outdated dependencies:
+
+```shell
+bundle outdated
+```
+
+### Updating dependencies
+
+Edit the `Gemfile` to update dependency versions, then update the
+`Gemfile.lock`:
+
+```shell
+bundle update
+```
+
+### Installing dependencies
+
+To install all dependencies:
+
+```shell
+bundle install
+```
+
+## Running Tests
+
+Before releasing, ensure all tests pass:
+
+```shell
+rake test
+```
+
+## Running linter
+
+To run linter:
+
+```shell
+bundle exec rake
+```
+
+To auto-correct issues:
+
+```shell
+bundle exec rubocop -A
+```
+
+## Publishing a Release
+
+1. **Update the version**: Bump the version number in `lib/uptrace/version.rb`
+
+2. **Build and publish the gem**:
+
+   ```shell
+   gem build uptrace.gemspec
+   bundle install
+   gem push uptrace-X.Y.Z.gem
+   ```
+
+   Replace `X.Y.Z` with the actual version number you specified in step 1.
+
+**Note**: Make sure you have the necessary permissions to push to the uptrace
+gem on RubyGems before attempting to publish.
