 ## Updating the metadata
 
-When any changes are made to elements associated with the pallets, such as extrinsic names or parameters, it is necessary to regenerate the metadata. Subxt is employed specifically for this purpose.

+### Updating the metadata of the supported runtimes (Pendulum/Amplitude/Foucoco)
+
+To update the metadata of the supported parachains, run the following commands:
+
+```
+subxt metadata -f bytes --url wss://rpc-pendulum.prd.pendulumchain.tech:443 > runtime/metadata-parachain-pendulum.scale --version 14
+subxt metadata -f bytes --url wss://rpc-amplitude.pendulumchain.tech:443 > runtime/metadata-parachain-amplitude.scale --version 14
+subxt metadata -f bytes --url wss://rpc-foucoco.pendulumchain.tech:443 > runtime/metadata-parachain-foucoco.scale --version 14
+```
+
+To facilitate comparison of changes in metadata, it is recommended to also convert the metadata to JSON format. This can
+be done using the following commands:
+
+```
+subxt metadata -f json --url wss://rpc-pendulum.prd.pendulumchain.tech:443 > runtime/metadata-parachain-pendulum.json --version 14
+subxt metadata -f json --url wss://rpc-amplitude.pendulumchain.tech:443 > runtime/metadata-parachain-amplitude.json --version 14
+subxt metadata -f json --url wss://rpc-foucoco.pendulumchain.tech:443 > runtime/metadata-parachain-foucoco.json --version 14
