+We use github to host code, to track issues and feature requests, as well as accept pull requests.
+
+## Pull Requests and [Changesets](https://github.com/changesets/changesets)
+
+Pull requests are the best way to propose changes to the codebase. We actively welcome your pull requests:
+
+1. Fork the repo and create your branch from `main`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation.
+4. Ensure the test suite passes.
+5. Make sure your code lints.
+6. Use a consistent coding style. Use prettier to format your code.
+7. Issue that pull request!

+# PoC Review Guide
+
+Cobuild is still under active development. Please refer to [ckb-transaction-cobuild-poc](https://github.com/cryptape/ckb-transaction-cobuild-poc) for contract supports.
+
+The core principle of the PoC is how the CKB system DAO would look like if it supports Cobuild.
+
+The general workflow to build transactions in Cobuild:
+
+1. Create an empty **BuildingPacket** structure to initiate building a new transaction.
+2. (Type Script Phase) Users perform some operations often by submitting forms. For each operation:
+    - a. Find the corresponding papp (name for dapp in Cobuid) and create an **Action**.
+    - b. Let the papp process the **Action**. Update transaction in the **BuildingPacket** structure and add the **Action** as a message Action to `BuildingPacketV1.message.actions`
+3. (Fee Estimation Phase) Estimate witnesses size for fee calculation.
+    - a. Ensure all message **Action**s have been completed.
+    - b. (Optional) Remove message **Action**s that are experimental. For example, before DAO updates its contract, the DAO operations as message **Action**s are not validated. It's better to remove it to avoid inconsistent data.
+    - c. For each lock script group: choose Cobuild or WitnessArgs layout and set the witness to enough size for fee estimation.
+    - d. If there're witnesses are using `SighashAll` or `SighashAllOnly`. Set the first of such witnesses to `SighashAll` and put message **Action**s into it, and the remaining to `SighashAllOnly`.
+    - e. If there's no such witnesses, and there's at least one message **Action**, add a `SighashAll` witness at a position beyond the number of inputs and save message **Action**s in it.
+    - f. Estimate tx size and pay fee. If there are new cells added, ensure the witness size is correct for fee estimation.
+4. (Lock Script Phase) Prepare to finalize the transaction. For each lock script group:
+    - a. Set witness for digest computation.
+    - b. Compute the digest for the script group.
+    - c. Connect wallet to create signatures from digests.
+    - d. Store the signature into the witness.
+5. Finish, send the transaction to CKB.
+
+## Map Code To Steps
+
+The core is the step 2. There will be a framework to handle 1, 3, 4, 5, I just build a minimal framework to make the PoC work.
+
+1. `src/lib/cobuild/types.js`: Cobuild data structures definition.
+2. `src/lib/papps/dao`: DAO papp
+    - a.
+        - `src/lib/papps/dao/schema.js`: Action.data schema
+        - `src/lib/papps/dao/action-creators.js`: Functions to create Action.data for DAO.
+    - b. `src/lib/papps/dao/lumos-callbacks.js`: Build transactions based on DAO message actions.
+3. `src/lib/cobuild/fee-manager.js`: See the function `payFee` and `storeWitnessForFeeEstimation`
+4. `src/lib/cobuild/lock-actions.js`: See the function `prepareLockActions`.
+    - a/b. `src/lib/cobuild/general-lock-actions.js`: See the function `prepareLockActionWithWitnessStore`
+    - c. `src/lib/wallet/selector.js` acts as a gateway to connect different wallets and create signatures.
+    - c. `src/lib/cobuild/general-lock-actions.js`: See the function `applyLockAction`
+5. `src/app/u/[wallet]/[connection]/submit-building-packet.js`: a simple UI to send tx and query its status.
+
+Remarks:
+
+- `src/lib/cobuild/react/building-packet-review.js`: UI to review the building packet for signing.
