There are 61 Maven artefacts: https://mvnrepository.com/artifact/io.datakernel?p=1&sort=newest
Some artefacts are very similar in name. E.g.: datakernel-launchers-common, datakernel-launchers-http, http-launchers, datakernel-launcher, datakernel-http.
This is making it confusing what artefacts to add to the project as https://datakernel.io/docs/core/http.html does not give what dependencies to add.
Assuming datakernel-launchers-common refers to: https://github.com/softindex/datakernel/tree/master/launchers/common there is no readme there also specifying what this does.
Elsewhere also the documentation is very thin: https://github.com/softindex/datakernel/tree/master/core-http and the referring link is broken: https://datakernel.io/docs/components/core/http.html
Also, some module documentation does not refer to what the relevant artefacts are. E.g. https://datakernel.io/docs/core/http.html
