+# Bash in Gitpod
+
+Bash is the default shell in Gitpod. But if you're developing Bash scripts yourself, you may want to configure additional language support for Bash.
+
+## Workspace Config
+
+### ShellCheck
+
+To use ShellCheck in Gitpod, first, we must install the `shellcheck` tool. Here is a Dockerfile to get you started.
+
+```Dockerfile
+FROM gitpod/workspace-full
+
+USER gitpod
+
+RUN brew install shellcheck
+```
+
+You should also install the shellcheck VS Code extension in Gitpod, e.g. by adding a [`.gitpod.yml`](https://www.gitpod.io/docs/41_config_gitpod_file/) configuration file to your repository that looks like this (notice the `vscode` extensions section):
+
+```yaml
+image:
+  file: .gitpod.Dockerfile
+
+vscode:
+  extensions:
+    - [email protected]:hsU/Rd39aqPYowTqL+DbXg==
+```
+
