DocsHoster is a free documentation hosting service for javadocs.
Documentations are organized with hierarchy -
[Organization] / [Project] / [Version]
E.g. The Spring Organization has projects for Spring Core, Spring Boot, Spring Binding .. etc. And each of these have their own versions.
So the first step is to add your Organization and project(s). Then you can further upload versions for each project. There are 3 ways to upload new versions -
In addition to serving documentation files, DocsHoster also provides search feature. This is irrespective of if the javadocs were created with search or not.
