 ### Download SRS File
 
-To create a ZKP you would need to download the correct SRS file (based on your circuit size). For example, if your circuit has around 65K constraints then you would need to download the following file https://storage.googleapis.com/zkevm/ptau/powersOfTau28_hez_final_16.ptau.
+To create a ZKP you would need to download the correct SRS file (based on your circuit size). For example, if your circuit has around 65K constraints then you would need to download an srs file of size 16;
 
-You can replace the number 16 in the above URL to download the correct SRS file for your circuit.

-> You can download the file to any location you wish. You will later provide the location of the file when running the CLI tool.

 This will lock 1,000 satoshis in the zkapp and return the transaction ID of the transaction that deployed the zkapp. A stateless zkapp can be referenced by that transaction ID.
 
 Bob can then unlock the funds from the stateless zkapp with the following command:
