+Here are the files that need to be updated when adding new ABI methods:
+
+`packages/networks/src/networks/vNaga/LitChainClient/contract-manager/createContractsManager.ts` is the file that creates the contracts manager. This is where use define the ABI signatures we want to use. We use the `@lit-protocol/contracts` package's constants `nagaDevSignatures` to get the ABI signatures. eg `nagaDevSignatures.PaymentDelegation`
+
+Networks are defined in the `packages/networks/src/networks` directory. For each network, it will be prefixed with `v` and the name of the network. Right now, there's only one network, `vNaga`. Then, within the network, we have different environments. For example, `vNaga/envs/naga-dev`.
+
+Then, for each environment, we have `createChainManager` which is essentially an object that binds the methods we want to expose to the user to the actual methods that are available on the chain.
+
+These methods are defined in the `packages/networks/src/networks/vNaga/LitChainClient/apis` directory. There are two types of methods:
+
+1. High-level methods: These are the methods that are exposed to the user. They are defined in the `packages/networks/src/networks/vNaga/envs/naga-dev/chain-manager/createChainManager.ts` file.
+2. Raw contract methods: These are the raw contract methods that are defined in the `packages/networks/src/networks/vNaga/LitChainClient/apis/rawContractApis` directory.
+
+For example, for payment manager, we are using the Ledger contract ABIs in the `packages/networks/src/networks/vNaga/LitChainClient/apis/rawContractApis/ledger` directory. Then, we will create a higher level methods in `packages/networks/src/networks/vNaga/LitChainClient/apis/highLevelApis/PaymentManager/PaymentManager.ts`
+
+Then, we need to update the `packages/lit-client/src/lib/LitClient/createLitClient.ts` file to add the new methods to the LitClient. (See getPaymentManager for an example). LitClient is the main entry point for the user to interact the Lit Protocol.
+
+Finally, we need to update the test in `e2e/src/e2e.spec.ts` to add the new methods to the test. See `e2e/src/helper/tests/pkp-permissions-manager-flow.ts` as reference.
+
+To ensure we have implemented correctly, we need to run this command:
+
+```
+NETWORK=naga-dev bun run test:e2e <test-name>
+```
+
+These are the ABI methods that need to be added:
