+Solr has lots of 3rd party dependencies, defined mainly in `versions.props`.
+Keeping them up-to-date is crucial for a number of reasons:
+
+* minimizing the risk of critical CVE vulnerabilities by staying on a recent and supported version
+* avoiding "dependency hell", that can arise from falling too far behind

+
+== Manual dependency upgrades
+In order to upgrade a dependency, you need to run through a number of steps:
+
+1. Identify the available versions from e.g. https://search.maven.org[Maven Central]
+2. Update the version in `versions.props` file
+3. Run `./gradlew --write-locks` to re-generate `versions.lock`. Note that this may cause a cascading effect where
+   the locked version of other dependencies also change.
+4. Run `./gradlew updateLicenses` to re-generate SHA1 checksums of the new jar files.
+5. Once in a while, a new version of a dependency will transitively bring in brand-new dependencies.
+   You'll need to decide whether to keep or exclude them. See `help/dependencies.txt` for details.
