 ## Command reference
 
-`wp-env` creates generated files in the wp-env home directory. By default, this is `~/.wp-env`. The exception is Linux, where files are placed at `~/wp-env` [for compatibility with Snap Packages](https://github.com/WordPress/gutenberg/issues/20180#issuecomment-587046325). The wp-env home directory contains a subdirectory for each project named `/$md5_of_project_path`. To change the wp-env home directory, set the `WP_ENV_HOME` environment variable. For example, running `WP_ENV_HOME="something" wp-env start` will download the project files to the directory `./something/$md5_of_project_path` (relative to the current directory).
