+# ic-cdk
+
+Canister Developer Kit for the Internet Computer.
+
+## Background
+
+On the Internet Computer, smart contracts come in the form of canisters which are WebAssembly modules.
+
+Canisters expose entry points which can be called both by other canisters and by parties external to the IC.
+
+This library aims to provide a Rust-ergonomic abstraction to implement Canister entry points.
+
+## Using `ic-cdk`
+
+In Cargo.toml:
+
+```toml
+[lib]
+crate-type = ["cdylib"]
+
+[dependencies]
+ic-cdk = "0.12"
+# Only necessary if you want to define Candid data types
+candid = "0.10" 
+```
+
+Then in Rust source code:
+
+```rust
+#[ic_cdk::query]
+fn hello() -> String{
+    "world".to_string()
+}
+```
+
+This will register a **query** entry point named `hello`.
+
+## Macros
+
+This library re-export macros defined in `ic-cdk-marcos` crate.
+
+The macros fall into two categories:
+
+* To register functions as canister entry points
+* To export Candid definitions
+
+### Register functions as canister entry points
+
+These macros are directly related to the [Internet Computer Specification](https://internetcomputer.org/docs/current/references/ic-interface-spec#entry-points).
+
+* [`init`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.init.html)
+* [`pre_upgrade`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.pre_upgrade.html)
+* [`post_upgrade`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.post_upgrade.html)
+* [`inspect_message`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.inspect_message.html)
+* [`heartbeat`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.heartbeat.html)
+* [`update`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.update.html)
+* [`query`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/attr.query.html)
+
+### Export Candid definitions
+
+* [`export_candid`](https://docs.rs/ic-cdk-macros/latest/ic_cdk_macros/macro.export_candid.html)
+
+Check [Generating Candid files for Rust canisters](https://internetcomputer.org/docs/current/developer-docs/backend/candid/generating-candid/) for more details.
+
+## More examples
+
+* [Basic examples](https://github.com/dfinity/cdk-rs/tree/main/examples): Demonstrate usage of `ic-cdk` API.
+* [Comprehensive examples](https://github.com/dfinity/examples/tree/master/rust): Illustrate how to build useful Rust canisters.
+
+## Manage Data Structure in Stable Memory
+
+Using `ic_cdk::storage::{stable_save, stable_restore}` API is easy but it doesn't scale well.
+
+[`ic-stable-structures`](https://crates.io/crates/ic-stable-structures) is recommended when you are dealing with multiple data structures with larger datasets.
