+## Shell Environment Detection (macOS and Linux)
+
+On macOS and Linux, ABP Studio starts a shell during application startup and imports the environment variables printed by it. This allows Studio to discover tools configured by shell startup files, such as user-managed .NET or Node.js installations. By default, Studio starts the shell as an interactive login shell and runs `env`.
+
+| Variable | Description | Fallback |
+|---|---|---|
+| `ABP_STUDIO_SHELL` | Overrides the shell executable used to load the environment. Set it to a valid, non-empty executable path. | When unset, `SHELL`, then `/bin/zsh` on macOS or `/bin/bash` on Linux |
+| `ABP_STUDIO_SHELL_ARGS` | Replaces the complete argument string passed to the selected shell. | When unset or empty, `-i -l -c 'env'` |
+
+Set these variables in the environment that launches ABP Studio, then restart the application. Usually, you only need to override the shell executable. For example:
+
+```bash
+export ABP_STUDIO_SHELL=/bin/bash
+export ABP_STUDIO_SHELL_ARGS="-i -l -c 'env'"
+```
+
+> **Note:** Custom `ABP_STUDIO_SHELL_ARGS` must make the shell exit successfully and print the environment to standard output as newline-separated `NAME=value` entries. These settings have no effect on Windows.
