 This library is a lightweight Node.js client derived from `node-crate` for interacting with CrateDB via its **HTTP endpoint**. Unlike libraries such as `node-postgres`, which use the PostgreSQL wire protocol, this client communicates with CrateDB's native HTTP API.
 
-> [!CAUTION] > **This library is primarily a proof of concept.**  
+> [!CAUTION]
 > While it provides basic functionality to interact with CrateDB, it is not production-ready and lacks the robustness of established libraries.

-> For production use, consider mature libraries like [`node-postgres`](https://node-postgres.com/) which leverage CrateDB's PostgreSQL compatibility. Use this client only for **testing, experimentation**, or if you know what you're doing. :wink:

 This library leverages modern JavaScript features — such as `JSON.rawJSON()` -
 to accurately serialize and deserialize `BigInt` values.
 
-### Serialization
-
-- **BigInt to LONG:**
-  When serializing, JavaScript `BigInt` values their precision is preserved.
-  e.g. `BigInt(12345678901234567890)` is serialized as `12345678901234567890`.
-
-### Deserialization
-
-- **Top-Level LONG Columns:**  
-  If type information is available in the result set, columns defined as CrateDB  
-  `LONG` are automatically converted to `BigInt`.
-
-- **Large Integer Values:**  
-  If type information is unavailable, integers exceeding `Number.MAX_SAFE_INTEGER`
-  and without a decimal point are converted to `BigInt` on a best-effort basis.
