+# GitHub Copilot Instructions
+
+## Code Writing Standards
+- Follow established code-writing standards for your language (spacing, comments, naming).
+- Consider internal coding rules for folder and function naming.
+- Follow the "boy scout rule": Always leave the codebase cleaner than you found it.
+
+## Comment Usage
+- Use comments sparingly and make them meaningful.
+- Avoid commenting on obvious things; use comments to explain "why" or unusual behavior.
+
+## Conditional Encapsulation
+- Encapsulate nested if/else statements into functions with descriptive names for clarity.
+
+## DRY Principle
+- Avoid code duplication; reuse code via functions, classes, modules, or libraries.
+- Modify code in one place if updates are needed.
+
+## Function Length & Responsibility
+- Write short, focused functions (single responsibility principle).
+- Break up long or complex functions into smaller ones.
+
+## General Code Style & Readability
+- Write readable, understandable, and maintainable code.
+- Prioritize clarity and adhere to coding standards.
+- Regularly review and refactor code for structure and maintainability.
+- Use version control (e.g., Git) for collaboration.
+
+## Naming Conventions
+- Use meaningful, descriptive names for variables, functions, and classes.
+- Names should reflect purpose and behavior; avoid names that require comments to explain intent.
+
+## Making your changes pass CI
+- Before submitting any changes
+  - Run the commands for formatting
+  - Run the linter command shown below
+  - Run tests for code you changed and everything that depends on it.
+- CI will reject code with formatting or linting issues.
+
+## Useful commands:
+- Format the code: `cargo fmt`
+- Lint and fix common mistakes: `RUSTFLAGS="-D dead-code -D nonstandard-style -D unused-imports -D unused-mut -D unused-variables -D unused-unsafe -D unreachable-patterns -D bad-style -D improper-ctypes -D unused-allocation -D unused-comparisons -D while-true -D unconditional-recursion -D bare-trait-objects -D function_item_references -D clippy::uninlined_format_args " cargo clippy --all --exclude wasmer-swift --locked --fix --allow-dirty -- -D clippy::all`
+- Build the cli: `cargo build -p wasmer-cli --features cranelift,llvm,wasmer-artifact-create,static-artifact-create,wasmer-artifact-load,static-artifact-load`
+- Test the cli: `cargo test -p wasmer-cli --features cranelift,llvm,wasmer-artifact-create,static-artifact-create,wasmer-artifact-load,static-artifact-load`
+- Test WASIX: `cargo test -p wasmer-wasix --features sys`
+- Convert a wasm module to wat (always limit the output with head/grep/tail): `wasm-tools print file.wasm`
+- Convert a wat module to wasm: `wasm-tools parse file.wat -o file.wasm`
+- For really hard debugging, creduce is available
+- Optimize a wasm module and strip debug info: `wasm-opt -O3 file.wasm -o file.opt.wasm`
+- Compile a C file to a WASIX module: `WASIXCC_WASM_EXCEPTIONS=1 WASIXCC_PIC=1 wasixcc -g -O0 file.c -o file.wasm`
