+
+            ### Downloads
+
+            Download the appropriate binary for your platform. The `libsecp256k1` library is optional but recommended for better cryptographic performance.
+
+            ### Installation
+
+            1. Download the binary for your platform
+            2. (Optional) Download the corresponding `libsecp256k1` library
+            3. Place both files in the same directory
+            4. Make the binary executable: `chmod +x orly-*`
+            5. Run: `./orly-*-linux-amd64` (or your platform's binary)
+
+            ### Verify Downloads
+
+            ```bash
+            sha256sum -c SHA256SUMS.txt
+            ```
+
+            ### Configuration
+
+            See the [repository documentation](https://git.mleku.dev/mleku/next.orly.dev) for configuration options.
