+# Documentation Standards - TeachLink Smart Contracts
+
+This document outlines the standard format for documenting smart contract interfaces in the TeachLink project. Consistent documentation improves developer experience and allows for automated documentation generation.
+
+## Doc Comment Standard
+
+All public-facing contract functions must use Rust doc comments (`///`) following this structure:
+
+1.  **Summary**: A one-line summary of what the function does.
+2.  **Description**: (Optional) Detailed explanation of the function's behavior, side effects, and logic.
+3.  **Arguments**: A `# Arguments` section listing each parameter with its name and description.
+4.  **Returns**: A `# Returns` section describing the return value.
+5.  **Errors**: An `# Errors` section listing potential error variants and the conditions under which they are returned.
+6.  **Events**: (Optional) An `# Events` section describing the events emitted by the function.
+7.  **Examples**: A `# Examples` section with one or more code snippets demonstrating how to use the function.
+
+### Template
+
+```rust
+/// [Summary]
+///
+/// [Detailed description...]
+///
+/// # Arguments
+///
+/// * `[arg1]` - [Description]
+/// * `[arg2]` - [Description]
+///
+/// # Returns
+///
+/// * `[ReturnType]` - [Description]
+///
+/// # Errors
+///
+/// * `[ErrorVariant]` - [Condition]
+///
+/// # Events
+///
+/// * `[EventSymbol]` - [Description]
+///
+/// # Examples
+///
+/// ```rust
+/// let result = contract.my_function(env, arg1, arg2);
+/// ```
+```
+
+## Automated Documentation Generation
+
+We use `cargo doc` to generate HTML documentation from these comments.
+
+### Commands
+
+```bash
+# Generate documentation
+cargo doc --no-deps --document-private-items
+
+# View documentation
+# open target/doc/teachlink/index.html
+```
+
+## CI/CD Validation
+
+The CI/CD pipeline ensures that:
+1.  All public functions have doc comments.
+2.  Documentation builds without errors.
+3.  Examples for public functions are present.
+
+To check for missing documentation locally:
+
+```bash
+cargo clippy -- -D missing-docs
+```
+
+(Note: You may need to enable `#![warn(missing_docs)]` in your crate root).
