+# Steel: Create account
+
+This "create-account" program is written using **Steel**, a framework for writing onchain programs.
+        
+## API
+- [`Error`](api/src/error.rs) - Custom defined errors.
+- [`Consts`](api/src/consts.rs) – Program constants.
+- [`Instruction`](api/src/instruction.rs) – Declared instructions.
+
+## Instructions
+- [`Initialize`](program/src/initialize.rs) – Initialize the account creation.
+
+## State
+- [`New Account`](api/src/state.rs) – Link account and the struct that stores unique user ID.
+
+## Get started
+
+Compile your program:
+```sh
+pnpm build
+```
+
+Run unit and integration tests:
+```sh
+pnpm test
+```
+
+Do both together:
+```sh
+pnpm build-and-test
+```
