+A temporary (placeholder) implementation of the `Wallet Contract`.
+
+See https://github.com/near/NEPs/issues/518.
+
+Must not use in production!
+
+To use the contract you need to make sure that this crate was compiled.
+The contract is built via `build.rs` and WASM file is generated to the `./res` directory.
+You might want to `touch build.rs` before `cargo build` to force cargo to generate the WASM file.
+
+If you want to use the contract from rust core, add
+
+```toml
+[dev-dependencies]
+near-wallet-contract = { path = "../near-wallet-contract" }
+```
+
+to the Cargo.toml and use `near_wallet_contract::wallet_contract()`.
+
+If you want to use a contract from an integration test, you can read
+the wasm file directly from the `./res` directory.
