-Quick start, installing all completers ~

-- Install YCM plugin via Vundle [26]
-- Install CMake
->
-  pkg install cmake
-<
-- Install xbuild, go, node and npm
-- Compile YCM
->
-  cd ~/.vim/bundle/YouCompleteMe
-  python3 install.py --all
-<
-- For plugging an arbitrary LSP server, check the relevant section

--------------------------------------------------------------------------------
-Explanation for the quick start ~
-
-These instructions (using 'install.py') are the quickest way to install
-YouCompleteMe, however they may not work for everyone. If the following
-instructions don't work for you, check out the full installation guide.
-
-**NOTE:** OpenBSD / FreeBSD are not officially supported platforms by YCM.
-
-Make sure you have a supported Vim version with Python 3 support, and a
-supported compiler and CMake, perhaps:
->
-  pkg install cmake
-<
-Install YouCompleteMe with Vundle [26].
-
-**Remember:** YCM is a plugin with a compiled component. If you **update** YCM
-using Vundle and the 'ycm_core' library APIs have changed (happens rarely), YCM
-will notify you to recompile it. You should then rerun the install process.
-
-Compiling YCM **with** semantic support for C-family languages through
-**clangd**:
->
-  cd ~/.vim/bundle/YouCompleteMe
-  ./install.py --clangd-completer
-<
-Compiling YCM **without** semantic support for C-family languages:
->
-  cd ~/.vim/bundle/YouCompleteMe
-  ./install.py
-<
-If the 'python' executable is not present, or the default 'python' is not the
-one that should be compiled against, specify the python interpreter explicitly:
->
-  python3 install.py --clangd-completer
-<
-The following additional language support options are available:
-
-- C# support: install Mono and add '--cs-completer' when calling
-  './install.py'.
-
-- Go support: install Go [31] and add '--go-completer' when calling
-  './install.py'.
-
-- JavaScript and TypeScript support: install Node.js and npm [32] and add
-  '--ts-completer' when calling 'install.py'.
-
-- Rust support: add '--rust-completer' when calling './install.py'.
-
-- Java support: install JDK 17 [33] and add '--java-completer' when calling
-  './install.py'.
-
-To simply compile with everything enabled, there's a '--all' flag. So, to
-install with all language features, ensure 'xbuild', 'go', 'node' and 'npm'
-tools are installed and in your 'PATH', then simply run:
->
-  cd ~/.vim/bundle/YouCompleteMe
-  ./install.py --all
-<
-That's it. You're done. Refer to the _User Guide_ section on how to use YCM.
-Don't forget that if you want the C-family semantic completion engine to work,
-you will need to provide the compilation flags for your project to YCM. It's
-all in the User Guide.
-
-YCM comes with sane defaults for its options, but you still may want to take a
-look at what's available for configuration. There are a few interesting options
-that are conservatively turned off by default that you may want to turn on.
