-### Docker setup
-
-Build the docker image with
-
-```shell
-docker build -t serena .
-```
-
-and run it with the repository mounted as a volume:
-
-```shell
-docker run -it --rm -v "$(pwd)":/workspace serena
-```
-
-You can also just run `bash docker_build_and_run.sh`, which will do both things
-for you.
-
-Note: For the Windows subsystem for Linux (WSL), you may need to adjust the path for the
-volume.

 ## Adding a New Supported Language
 
-Serena interacts with code through language servers which are included in
-the `solidlsp` package. It is rather easy to include a new supported language
-if an LSP implementation for it exists. You just need to:
-
-1. create a new subclass of `SolidLanguageServer`
-2. add a new value to the `Language` enum
-3. make a new `elif` case in the `SolidLanguageServer.create` method
-4. add a test repo of the new language to `test/resources/repos/<new_language>/test_repo`
-   and new tests in `test/solidlsp/<new_language>`. Similar to existing tests for other languages
-5. also add a new case to the parameterized tests in `test/serena/test_serena_agent`
-
-The subclasses are typically easy to write, have a look at the 
-[PyrightLanguageServer](src/multilspy/language_servers/pyright_language_server/pyright_server.py) 
-for an example, or at any other implementation to see how non-python
-dependencies for language servers are handled there.
-There are also some tips from the multilspy admin [here](https://github.com/microsoft/multilspy/issues/5).
