+# Synthetic DNA → Amino Acid ORF Translation Dataset
+
+## 🧬 Summary
+
+This dataset contains **synthetic DNA sequences** (`input`) and their corresponding **amino acid sequences** (`output`), where the label is defined as the **first valid ORF** from the 5' end:
+
+> From the **first `ATG`** (start codon) encountered in the sequence  
+> to the **first in-frame stop codon** (`TAA`, `TAG`, or `TGA`) that follows it,  
+> translated into amino acids (excluding the stop).
+
+The dataset is designed for training and evaluating models that learn **DNA→protein translation rules** and **ORF detection** in a slightly non-trivial, noisy setting.

+## 📁 Dataset Structure
+
+### Data fields
+
+Each example is a JSON object with the following fields:
+
+- `input` (string):  
+  A DNA sequence (characters `A`, `C`, `G`, `T` only).  
+  - Length is **variable**, from a minimum (e.g. 6 nt) up to a specified maximum.
+  - The sequence is mostly random, but guaranteed to contain at least one valid ORF.
+
+- `output` (string):  
+  The amino acid sequence translated from the ORF defined as:
+  - The first `ATG` found when scanning from the 5' end.
+  - The first **in-frame** stop codon (`TAA`, `TAG`, or `TGA`) after that `ATG`.
+  - Translation uses the **standard genetic code**.
+  - The stop codon is **not included** in the amino acid string.
+
+Example (conceptual):
+
+```json
+{
+  "input": "ACGTTGATGAAAACCGGGTAGTTCG...",
+  "output": "MKTVG"
