+*Note: You can add `-l` to specify the directory where the directive `include` should look for the circuits indicated. For our repo, use `circom -l node_modules` instead of `circom`. Additionally, we generally recommend using the `--O0` flag for optimization during compilation for beginners. However, if you're more experienced with Circom, feel free to use the `--O1` flag instead. It's important to avoid using the `--O2` flag as that is the default setting and it may lead to the deletion of additional constraints.*
 
 After running this command, the circuit will be compiled into a `.r1cs` file, a `.wasm` file, and a `.sym` file. These files are used in the next steps to generate the proving and verifying keys, and to compute the witness.

 ## Step 5: Compute the Witness
 
 The process of creating a proof involves ensuring that all signals in the file adhere to the existing constraints. This is achieved by computing the witness using the Wasm file generated during compilation.

-After obtaining the constraint size, find the next highest power of 2 and replace the '12' in the following command with that number. This command initiates the Powers of tau ceremony.

-This template includes a collection of utility functions used across multiple circuits, such as bit manipulation functions, comparison functions, or conversion functions.
+The `utils.circom` file includes a collection of utility templates and functions that are used across multiple circuits. These utilities cover a wide range of functionalities, including bit manipulation, comparison, conversion, and arithmetic operations in finite fields. It serves as a foundational component for building complex arithmetic circuits.
+
+## Utility templates
+
+### bytes2ints.circom
+
+This template converts an array of bytes into an array of integers. It is designed to handle inputs of any byte size and outputs integers based on the number of bytes specified. This is particularly useful for processing large binary data within arithmetic circuits.
+
+### constants.circom
+
+This file defines a set of constants used across various templates within the `circuits` package. These constants include maximum sizes for emails, domains, invitation codes, and timestamps, as well as specifications for packing bytes into field elements.
+
+### digit2int.circom
+
+The `Digit2Int` template converts an array of digit characters (0-9) into their corresponding integer representation. This is useful for processing numeric data that is input as a sequence of characters.
+
+### hex2int.circom
+
+This template provides functionality for converting hexadecimal strings into their integer representation. It supports conversion of both lowercase (a-f) and uppercase (A-F) hexadecimal characters. This is essential for processing hexadecimal data within arithmetic circuits.
