we only have 1 input param so don't need shift: when shift fails
it would cause the script to exit early due to set -e

* fix: run in proper environment

* fix: start docker when needed

* chore: cleanup docker

* fix: another fix from shell script refactor

* ci: add docker to bedrock tests

* fix(ci): move remote docker from contracts-bedrock-tests to contracts-bedrock-checks

* ci: maybe docker setup needs to come earlier

* fix: various changes so make-summary-deployment works in docker

- avoid copying node_modules to container, which caused a symlink error
- fix which script commands are run in docker
- restore order of setup_remote_docker step

* fix: bind mount instead of copy into docker

* style: remove unneded braces

* fix: -v to create dir on docker, restore file copying

* fix: copy new files

* fix permissions error

+## Getting Started
+
+### Overview
 
-### Root folder
+[Kontrol](https://github.com/runtimeverification/kontrol) is a tool by [Runtime Verification](https://runtimeverification.com/) (RV) that enables formal verification of Ethereum smart contracts. Quoting from the Kontrol [docs](https://docs.runtimeverification.com/kontrol/overview/readme):
 
-- [`pausability-lemmas.k`](./pausability-lemmas.k): File containing the necessary lemmas for this project
-- [`deployment`](./deployment): Custom deploy sequence for Kontrol proofs and tests for its summarization
-- [`proofs`](./proofs): Where the proofs of the project live
-- [`scripts`](./scripts): Where the scripts of the projects live
+> Kontrol combines [KEVM](https://github.com/runtimeverification/evm-semantics) and [Foundry](https://book.getfoundry.sh/) to grant developers the ability to perform [formal verification](https://en.wikipedia.org/wiki/Formal_verification) without learning a new language or tool. This is especially useful for those who are not verification engineers. Additionally, developers can leverage Foundry test suites they have already developed and use symbolic execution to increase the level of confidence.
+>
+> KEVM is a tool that enables formal verification of smart contracts on the Ethereum blockchain. It provides a mathematical foundation for specifying and implementing smart contracts. Developers can use KEVM to rigorously reason about the behavior of their smart contracts, ensuring correctness and reducing the likelihood of vulnerabilities in the contract code.

-### [`scripts`](./scripts) folder
+## Usage
 
-- [`make-summary-deployment.sh`](./scripts/make-summary-deployment.sh): Executes [`KontrolDeployment.sol`](./KontrolDeployment.sol), curates the result and writes the summary deployment contract

+Verifying proofs has two steps: build, and execute.
 
-## Verification execution
+### Build Deployment Summary
 
-The verification execution consists of two steps, although the first step may be omitted to use the committed version. There's one script to run per step. These scripts should be run from the [`contracts-bedrock`](../../) directory.
+First, generate a deployment summary contract from the deploy script in [`KontrolDeployment.sol`](./deployment/KontrolDeployment.sol) by running the following command:
 
-1. Generate a deployment summary contract from [`KontrolDeployment.sol`](./KontrolDeployment.sol)
 ```bash
-  ./test/kontrol/scripts/make-summary-deployment.sh
+./test/kontrol/scripts/make-summary-deployment.sh
 ```
-This step is optional. The default summary can be found [here](./proofs/utils/DeploymentSummary.sol), which is the summarization of the [`KontrolDeployment.sol`](./KontrolDeployment.sol) script.
 
-2. Execute the tests in [`OptimismPortal.k.sol`](./proofs/OptimismPortal.k.sol)
-```bash
-  ./test/kontrol/scripts/run-kontrol.sh $option
+[`KontrolDeployment.sol`](./deployment/KontrolDeployment.sol) contains the minimal deployment sequence required by the proofs.
+The [`make-summary-deployment.sh`](./scripts/make-summary-deployment.sh) script will generate a JSON state diff. This state diff is used in two ways by Kontrol.
+First, Kontrol generates a summary contract recreating the state diffs recorded in the JSON. This contract is used to test that the information contained in the generated JSON is correct and aids in the specification of the symbolic property tests. The generation of this contract is also handled by the `make-summary-deployment.sh` script.
+Second, the state diff JSON is used to load the post-deployment state directly into Kontrol when running the proofs.
+
+This step is optional if an up-to-date summary contract already exists, which will be the case until the `KontrolDeployment` contract changes, or any of the source contracts under test change.
+See the [Implementation Details](#implementation-details) section for more information, and to learn about the CI check that ensures the committed autogenerated files from this step are up-to-date.
+
+The summary contract can be found in [`DeploymentSummary.sol`](./proofs/utils/DeploymentSummary.sol), which is summarization (state changes) of the [`KontrolDeployment.sol`](./deployment/KontrolDeployment.sol) contract.
+
+### Execute Proofs
+
+Use the [`run-kontrol.sh`](./scripts/run-kontrol.sh) script to runs the proofs in all `*.k.sol` files.
+
+```
+./test/kontrol/scripts/run-kontrol.sh [container|local|dev]
 ```
-See below for further documentation on `run-kontrol.sh`.
 
-### `run-kontrol.sh` script
-The `run-kontrol.sh` script handles all modes of proof execution. The modes, corresponding to the available arguments of the script, are the following:
-- `container`: Run the proofs in the same docker image used in CI. The intended use case is CI debugging. This is the default execution mode, meaning that if no arguments are provided, the proofs will be executed in this mode.
-- `local`: Run the proofs with your local Kontrol install, enforcing the version to be the same as the one used in CI. The intended use case is running the proofs without risking discrepancies because of different Kontrol versions.
+The `run-kontrol.sh` script supports three modes of proof execution:
+
+- `container`: Runs the proofs using the same Docker image used in CI. This is the default execution mode—if no arguments are provided, the proofs will be executed in this mode.
+- `local`: Runs the proofs with your local Kontrol install, and enforces that the Kontrol version matches the one used in CI, which is specified in [`versions.json`](../../../../versions.json).
 - `dev`: Run the proofs with your local Kontrol install, without enforcing any version in particular. The intended use case is proof development and related matters.
 
 For a similar description of the options run `run-kontrol.sh --help`.
 
-## Kontrol Foundry profiles
+### Add New Proofs
+
+More details on best practices for writing and adding new proofs will be added here in the future.
+The summary is:
+
+1. Update the deployment summary and its tests as needed.
+2. Write the proofs in an appropriate `*.k.sol` file in the `proofs` folder.
+3. Add the proof name to the `test_list` array in the [`run-kontrol.sh`](./scripts/run-kontrol.sh) script.
+
+## Implementation Details
+
+### Assumptions
+
+1. A critical invariant of the `KontrolDeployment.sol` contract is that it stays in sync with the original `Deploy.s.sol` contract.
+   Currently, this is partly enforced by running some of the standard post-`setUp` deployment assertions in `DeploymentSummary.t.sol`.
+   A more rigorous approach may be to leverage the `ChainAssertions` library, but more investigation is required to determine if this is feasible without large changes to the deploy script.
+
+2. Until symbolic bytes are natively supported in Kontrol, we must make assumptions about the length of `bytes` parameters.
+   All current assumptions can be found by searching for `// ASSUME:` comments in the files.
+   Some of this assumptions can be lifted once [symbolic bytes](https://github.com/runtimeverification/kontrol/issues/272) are supported in Kontrol.
+
+### Deployment Summary Process
+
+As mentioned above, a deployment summary contract is first generated before executing the proofs.
+This is because the proof execution leverages Kontrol's [fast summarization](https://github.com/runtimeverification/kontrol/pull/271) feature, which allows loading the post-`setUp` state directly into Kontrol.
+This provides a significant reduction in proof execution time, as it avoids the need to execute the deployment script every time the proofs are run.
 
-This project uses two different [Foundry profiles](../../foundry.toml), `kdeploy` and `kprove`.
+All code executed in Kontrol—even when execution is concrete and not symbolic—is significantly slower than in Foundry, due to the mathematical representation of the EVM in Kontrol.
+Therefore we want to minimize the amount of code executed in Kontrol, and the fast summarization feature allows us to reduce `setUp` execution time.
 
-- `kdeploy`: This profile is used to generate a summary contract from the execution of the [`KontrolDeployment.sol`](./KontrolDeployment.sol) script. In particular, the `kdeploy` profile is used by the [`make-summary-deployment.sh`](./scripts/make-summary-deployment.sh) script to generate the [deployment summary contract](./proofs/utils/DeploymentSummary.sol). The summary contract is then used with the `kprove` profile to load the post-setUp state directly into Kontrol. We don't need the output artifacts from this step, so we save them to the `kout-deployment` directory, which is not used anywhere else. We also point the script path to the `scripts-kontrol` directory, which does not exist, to avoid compiling scripts we don't need, which reduces execution time.
+This project uses two different [`foundry.toml` profiles](../../foundry.toml), `kdeploy` and `kprove`, to facilitate usage of this fast summarization feature.:
 
-- `kprove`: This profile is used by the [`run-kontrol.sh`](./scrpts/run-kontrol.sh) script, which needs to be run after executing [`./test/kontrol/script/make-summary-deployment`](./scripts/make-summary-deployment.sh) (this last script uses the `kdeploy` profile). The proofs are executed using the `kprove` profile. The `src` directory points to a test folder because we only want to compile what is in the `test/kontrol/proofs` folder since it contains all the deployed bytecode and the proofs. We similarly point the script path to a non-existent directory for the same reason as above. The `out` folder for this profile is `kout-proofs`.
+- `kdeploy`: Used by [`make-summary-deployment.sh`](./scripts/make-summary-deployment.sh) to generate the `DeploymentSummary.sol` contract based on execution of the `KontrolDeployment.sol` contract using Foundry's state diff recording cheatcodes.
+  This is where all necessary [`src/L1`](../../src/L1) files are compiled with their bytecode saved into the `DeploymentSummaryCode.sol` file, which is inherited by `DeploymentSummary`.
 
-Note that the compilation of the necessary `src/L1` files is done with the `kdeploy` profile, and the results are saved into [`test/kontrol/proofs/utils/DeploymentSummary.sol`](./proofs/utils/DeploymentSummary.sol). So, when running the `kprove` profile, the deployed bytecode of the `src/L1` files are recorded in the automatically generated file `test/kontrol/proofs/utils/DeploymentSummaryCode.sol`.
+- `kprove`: Used by the [`run-kontrol.sh`](./scrpts/run-kontrol.sh) script to execute proofs, which can be run once a `DeploymentSummary.sol` contract is present. This profile's `src` and `script` paths point to a test folder because we only want to compile what is in the `test/kontrol/proofs` folder, since that folder contains all bytecode and proofs.
 
-## References
+The `make-summary-deployment.sh` scripts saves off the generated JSON state diff to `snapshots/state-diff/Kontrol-Deploy.json`, and is run as part of the `snapshots` script in `package.json`.
+Therefore, the snapshots CI check will fail if the committed Kontrol state diff is out of sync.
+Note that the CI check only compares the JSON state diff, not the generated `DeploymentSummary.sol` or `DeploymentSummaryCode` contracts.
+This is for simplicity, as those three files will be in sync upon successful execution of the `make-summary-deployment.sh` script.
+We commit the `DeploymentSummary.sol` and `DeploymentSummaryCode.sol` contracts, because forge fails to build if those contracts are not present—it is simpler to commit these autogenerated files than to workaround their absence in forge builds.
 
-[Kontrol docs](https://docs.runtimeverification.com/kontrol/overview/readme)
+During `make-summary-deployment.sh`, the `mustGetAddress` usage in `Deploy.s.sol` is temporarily replaced by `getAddress`—the former reverts if the deployed contract does not exist, while the latter returns the zero address.
+This is required because the deploy script in `KontrolDeployment.sol` is does not fully reproduce all deployments in `Deploy.s.sol`, so the `mustGetAddress` usage would cause the script to revert since some contracts are not deployed.
+`KontrolDeployment.sol` is a simplified, minimal deployment sequence for Kontrol proofs, and is not intended to be a full deployment sequence for the contracts in `contracts-bedrock`.
