-**Hello world!!!**
+# Block for inserting/upserting THX attributes into the thx table
+
+This block is responsible for inserting or updating THX-related records in the `thx` table using the same database configuration as `db_push_v1`.
+
+## Table DDL
+
+The following DDL illustrates the `thx` table structure (Postgres style, conceptually compatible with DuckDB for tests):
+
+```sql
+-- creating thx table
+CREATE TABLE IF NOT EXISTS thx (
+    application_key TEXT PRIMARY KEY,
+    application_timestamp TIMESTAMP NULL,
+    digital_id_first_seen TEXT NULL,
+    summary_risk_score TEXT NULL,
+    cpu_clock TEXT NULL,
+    true_ip_first_seen TEXT NULL,
+    ssn_hash_first_seen TEXT NULL,
+    account_email_attributes TEXT NULL,
+    tps_ip_latitude TEXT NULL,
+    tps_ip_longitude TEXT NULL,
+    account_telephone_first_seen TEXT NULL,
+    account_login_first_seen TEXT NULL
+);
+
+CREATE INDEX IF NOT EXISTS idx_thx_application_key ON thx(application_key);
+CREATE INDEX IF NOT EXISTS idx_thx_application_timestamp ON thx(application_timestamp);
+```
