+# Contributing to bump-everywhere
+
+First off, thanks for taking the time to contribute! 💓
+
+You can contribute by:
+
+- creating pull requests,
+- creating or responding to [issues](https://github.com/undergroundwires/bump-everywhere/issues),
+- supporting the development and maintainance by [sponsoring me on GitHub](https://github.com/sponsors/undergroundwires) with a single time donation or reccuring donations, see more options in [undergroundwires.dev/donate](https://undergroundwires.dev/donate/),
+- giving the project a star,
+- or adding a badge in a project you use bump-everywhere, see [support](./README.md#support).
+
+## Development environment
+
+If you're using visual studio code, [recommended extensions](./.vscode/extensions.json) would install useful linters and extensions.
+
+## Style guide
+
+- Do not introduce any TODO comments, fix them or do not introduce the change.
+- Use common sense, simpler is better.
+
+### Shell scripting
+
+- Use [ShellCheck](https://www.shellcheck.net/) to lint your code.
+- Always check for return values.
+- Declare function-specific variables as `local`.
+- Declare variables as readonly whenever possible.
+  - E.g. `local -r ..`, `declare -r ..` or `readonly ..`.
+- Send all errors messages to stderr.
+  - E.g. `>&2 echo 'Error!'`.
+- Use always `#!/usr/bin/env bash` shebang.
+- Wrap long lines.
+- Use `[[ … ]]` over `[ … ]`, `test`.
+- Avoid eval at all cost.
+
+#### Naming conventions
+
+**Source file names:**
+
+- Use `kebab-case.sh`.
+- For tests, use `.test` suffix such as `<system-under-test>.test.sh`.
+
+**Function names:**
+
+- Use snake_case. E.g. `my_func() { ... }`
+- Prefix functions in files that others files source with a scope name and `::`. E.g. `utilities::has_value() { }`.
+
+**Variable names**:
+
+- Use snake_case for local variables.
+- Use ALL_CAPS_SEPARATED_WITH_UNDERSCORES for constant and environment variable names.
