+## Endianness considerations for FP32 format
+
+When using the FP32 blob format with vector set commands like [`VADD`]({{< relref "/commands/vadd" >}}) and [`VSIM`]({{< relref "/commands/vsim" >}}), the binary data must be encoded in little-endian byte order. This is important for cross-platform compatibility, as some ARM variants and other architectures may use different endianness.
+
+If your platform uses big-endian or mixed-endian encoding, you have two options:
+- Manually convert the byte order to little-endian before passing the blob to Redis.
+- Use the `VALUES` syntax instead, which accepts floating-point numbers as strings and is platform-independent.

 The following examples give an overview of how to use vector sets. For clarity,
