+[example demonstrates]: https://github.com/stellar/soroban-examples/tree/v0.9.2/hello_world
+[other example]: getting-started/
+
+## Run the Example
+
+First go through the [Setup] process to get your development environment
+configured, then clone the `v0.9.2` tag of `soroban-examples` repository:
+
+```bash
+git clone -b v0.9.2 https://github.com/stellar/soroban-examples
+```
+
+Or, skip the development environment setup and open this example in
+[Gitpod][oigp].
+
+To run the tests for the example, navigate to the `hello_world` directory, and
+use `cargo test`.
+
+```bash
+cd hello_world
+cargo test
+```
+
+You should see the output:
+
+```bash
+running 1 test
+test test::test ... ok
+```
+
+[Setup]: ./getting-started/setup.mdx
+
+## Code
+
+```rust title="hello_world/src/lib.rs"
+#![no_std]
+use soroban_sdk::{contractimpl, vec, Env, Symbol, Vec};
+
+pub struct HelloContract;
+
+#[contractimpl]
+impl HelloContract {
+    pub fn hello(env: Env, to: Symbol) -> Vec<Symbol> {
+        vec![&env, Symbol::short("Hello"), to]
+    }
+}
+
+mod test;
+```
+

+
+## How it Works
+
+This is the written part of each guide. You can call out each thing unique to
+this contract, sometimes referencing other important concepts from other example
+contracts, too.
+
+### Major Concepts
+
+You could add sub-headings for highlighting even further important bits or
+concepts to know. The `events` example guide has the following `h3` headings:
+
+- Event Topics
+- Event Data
+- Publishing
+
+Underneath each of those headings is a brief discussion of how that concept ties
+into the example contract code.
+
+## Tests
+
+Open the `/hello_world/src/test.rs` file to follow along.
+
+```rust title="hello_world/src/test.rs"
+#![cfg(test)]
+
+use super::*;
+use soroban_sdk::{vec, Env, Symbol};
+
+#[test]
+fn test() {
+    let env = Env::default();
+    let contract_id = env.register_contract(None, HelloContract);
+    let client = HelloContractClient::new(&env, &contract_id);
+
+    let words = client.hello(&Symbol::short("Dev"));
+    assert_eq!(
+        words,
+        vec![&env, Symbol::short("Hello"), Symbol::short("Dev"),]
+    );
+}
+```
+
+You can describe what's happening in the above test here. Some of the stuff will
+likely be the same from one guide to another. It looks like, in particular, the
+following chunk is shared among a few of them:
+
+{/* BEGIN shared chunk */}
+
+In any test the first thing that is always required is an `Env`, which is the
+Soroban environment that the contract will run in.
+
+```rust
+let env = Env::default();
+```
+
+The contract is registered with the environment using the contract type.
+
+```rust
+let contract_id = env.register_contract(None, IncrementContract);
+```
+
+All public functions within an `impl` block that is annotated with the
+`#[contractimpl]` attribute have a corresponding function generated in a
+generated client type. The client type will be named the same as the contract
+type with `Client` appended. For example, in our contract the contract type is
+`Contract`, and the client is named `ContractClient`.
+
+{/* /END shared chunk */}
+
+Then you can describe the intricacies of what your contract test does uniquely.
+
+## Build the Contract
+
+To build the contract, use the `cargo build` command.
+
+```bash
+cargo build --target wasm32-unknown-unknown --release
+```
+
+A `.wasm` file should be outputted in the `target` directory:
+
+```bash
+target/wasm32-unknown-unknown/release/soroban_hello_world_contract.wasm
+```
+
+## Run the Contract
+
+If you have [`soroban-cli`] installed, you can invoke contract functions using
+it.
+
+```bash
+soroban contract invoke \
+    --wasm target/wasm32-unknown-unknown/release/soroban_hello_world_contract.wasm \
+    --id 1 \
+    -- \
+    hello \
+    --to Soroban
+```
+
+## Further Reading
+
+If you have some further links to share or background knowledge you can link to,
+this is the place to share it. Or, maybe you want to point out how this example
+is similar or not when compared with other examples.
