+## Example Client
+
+See the examples folder for a simple example client.
+To create an SmartID account, download the app:
+[SmartID App](https://www.smart-id.com/download/)
+
+The example application goes through the following use cases:
+- Verify Certificate Existence
+- SmartID Authentication
+- SmartID Digital Signature
+
+The example is using a MOCK ID to simulate the SmartID user.
+
+```shell
+cargo run --example smart_id_client
+```
+
+### Configuration
+SmartID configuration can be loaded form environment variables:
+```shell
+/// Get default Config (from environment variables)
+let cfg = get_config_from_env();
+```
+
+Or using the builder pattern:
+```shell
+/// Config Builder
+let cfg = SmartIDConfigBuilder::new().url("https://sid.demo.sk.ee/smart-id-rp/v2").build().expect("Error building config");
+```
+
+### Verify Certificate Existence
+
+To check whether a user has been onboarded, use the `get_certificate_by_semantic_identifier`:
+```shell
+async fn uc_get_certificate_choice(cfg: &SmartIDConfig) -> Result<()> {
+
+    /// Create the semantic identifier
+    let sem_id = SemanticsIdentifier::new_from_enum_mock(IdentityType::PNO, CountryCode::BE);
+
+    /// Verify if a certificate exists for given id
+    let res = get_certificate_by_semantic_identifier(&cfg, sem_id).await;
+    match res {
+        Ok(r) => {
+            let cert = validate_response_success(r).map(|res| res.cert.unwrap().value.unwrap())?;
+            info!("Smart ID Certificate {:#?}", cert);
+            Ok(())
+        }
+        Err(_) => Err(anyhow::anyhow!("Error getting certificate"))
+    }
+}
+```
+
+### SmartID Authentication
+
+To authenticate a user, use the `authenticate_by_semantic_identifier`:
+```shell
+async fn uc_authenticate_by_semantic_identifier(cfg: &SmartIDConfig) -> Result<()> {
+    /// Create the semantic identifier
+    let sem_id = SemanticsIdentifier::new_from_enum_mock(IdentityType::PNO, CountryCode::BE);
+
+    /// Define interactions
+    let interactions: Vec<Interaction> = vec![Interaction::diplay_text_and_pin("Authenticate to Application: ReadMyCards")];
+
+    /// Create hash
+    let hash_type = HashType::SHA256;
+    let hash = sha_digest("This is a test string".to_string().into_bytes(), &hash_type)?;
+    let b64_hash =  base64::engine::general_purpose::STANDARD.encode(hash.as_ref());
+    let verification_code_for_user = generate_verification_number(hash.as_ref().to_vec())?;
+    info!("Verification code for user: {}", verification_code_for_user);
+
+    /// Ask user for authentication
+    let res = authenticate_by_semantic_identifier(&cfg, sem_id, interactions, b64_hash, hash_type).await;
+
+    match res {
+        Ok(r) => {
+            let session_result = validate_response_success(r).map(|res| res.result)?;
+            info!("Smart ID Authentication result {:#?}", session_result);
+            Ok(())
+        }
+        Err(_) => Err(anyhow::anyhow!("Error during authentication"))
+    }
+}
+```
+
+### SmartID Digital Signature
+
+To sign a document as a user, use the `sign_by_semantic_identifier`:
+```shell
+async fn uc_sign_by_semantic_identifier(cfg: &SmartIDConfig) -> Result<()> {
+    /// Create the semantic identifier
+    let sem_id = SemanticsIdentifier::new_from_enum_mock(IdentityType::PNO, CountryCode::BE);
+
+    /// Define interactions
+    let interactions: Vec<Interaction> = vec![Interaction::confirmation_message("Are you sure to sign document: something.pdf?"), Interaction::diplay_text_and_pin("Sign using ReadMyCards")];
+
+    /// Create hash
+    let hash_type = HashType::SHA256;
+    let hash = sha_digest("This is a test string".to_string().into_bytes(), &hash_type)?;
+    let b64_hash =  base64::engine::general_purpose::STANDARD.encode(hash.as_ref());
+
+    /// Create verification cod
+    let verification_code_for_user = generate_verification_number(hash.as_ref().to_vec())?;
+    info!("Verification code for user: {}", verification_code_for_user);
+
+    /// Ask user to sign
+    let res = sign_by_semantic_identifier(&cfg, sem_id, interactions, b64_hash, hash_type).await;
+    match res {
+        Ok(r) => {
+            match validate_response_success(r).map(|res| res.signature)? {
+                None => {
+                    warn!("No signature");
+                    Ok(())
+                }
+                Some(signature) => {
+                    info!("Smart ID signature result {:#?}", signature);
+                    Ok(())
+                }
+            }
+        }
+        Err(_) => Err(anyhow::anyhow!("Error signing digest"))
+    }
+}
+```
