The dist folder contains all the distributions that can be used as deployment artifacts in other servers. It contains the main Solr file, which is solr-core.7.1.0.jar. This folder also contains JAR files of all the contribs we discussed earlier. You can deploy these artifacts to any application server as per your needs.

The docs folder contains online documentation for all the help needed in Solr. It has Wiki Docs, new changes in the current version, minimum system requirements, tutorials, Lucene documentation, and Java API docs for all the contrib modules.
