+--- `pylyzer`, a fast static code analyzer & language server for Python.
+---
+--- `pylyzer` requires Erg as dependency, and finds it via `ERG_PATH` environment variable.
+--- This config sets `ERG_PATH="~/.erg"`. Set `cmd_env` if you want to change it.
+--- To install Erg, simply extract tarball/zip from [Erg releases](https://github.com/erg-lang/erg/releases/latest)
+--- to the the path where you want to install it, e.g. `~/.erg`.
