+  and learning from the experience

+  any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,

+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[email protected].
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.

-# Shopify Function Wasm API
+# Shopify Function WASM API
+
+A high-performance API for building Shopify Functions using WebAssembly (WASM).
+
+## Architecture
+
+The WASM API consists of these main components:
+
+1. **Provider (`provider/`)**
+    - Implements low-level WASM operations for:
+        - Reading function input
+        - Serializing the function output
+
+2. **Core (`core/`)**
+    - Defines common types used by the `providers` and `api`
+
+3. **API (`api/`)**
+    - Provides a high-level interface for interacting with the provider
+    - Abstracts away low-level WASM details
+    - Includes examples and documentation
+
+4. **Trampoline (`trampoline/`)**
+    - CLI tool that augments WASM modules to interface with the provider
+    - Handles memory sharing between guest and provider modules
+    - Creates the necessary WASM imports/exports
+
+## Getting Started
+
+### Prerequisites
+
+- [Rust](https://www.rust-lang.org/tools/install) (latest stable version)
+
+### Basic Usage
+
+Here's a simple example of how to use the API:
+
+```rust
+fn main(context: &mut Context) -> Result<()> {
+    let input = context.input_get()?;
+
+    // Function logic
+
+    context.finalize_output()?;
+
+    Ok(())
+}
+```
+
+To build a function example, create a new example and build it targeting `wasm32-wasip1`:
+
+```shell
+cargo build --release --target wasm32-wasip1 -p shopify_function_wasm_api --example echo
+```
+
+
+The trampoline tool bridges communication between your Wasm module and the provider module. To trampoline your Wasm module:
+
+```shell
+# Short flags
+cargo run -p shopify_function_wasm_api_trampoline -- -i input.wasm -o output.wasm
+```
+
+For examples, check out the [examples directory](./api/examples/).
+
