+# Developing
+
+If you have recently created a contract with this template, you probably could use some
+help on how to build and test the contract, as well as prepare it for production. This
+file attempts to provide a brief overview, assuming you have installed a recent
+version of Rust already (eg. 1.58.1+).
+
+## Prerequisites
+
+Before starting, make sure you have [rustup](https://rustup.rs/) along with a
+recent `rustc` and `cargo` version installed. Currently, we are testing on 1.58.1+.
+
+And you need to have the `wasm32-unknown-unknown` target installed as well.
+
+You can check that via:
+
+```sh
+rustc --version
+cargo --version
+rustup target list --installed
+# if wasm32 is not listed above, run this
+rustup target add wasm32-unknown-unknown
+```
+
+## Compiling and running tests
+
+Now that you created your custom contract, make sure you can compile and run it before
+making any changes. Go into the repository and do:
+
+```sh
+# this will produce a wasm build in ./target/wasm32-unknown-unknown/release/YOUR_NAME_HERE.wasm
+cargo wasm
+
+# this runs unit tests with helpful backtraces
+RUST_BACKTRACE=1 cargo unit-test
+
+# auto-generate json schema
+cargo schema
+```
+
+### Understanding the tests
+
+The main code is in `src/contract.rs` and the unit tests there run in pure rust,
+which makes them very quick to execute and give nice output on failures, especially
+if you do `RUST_BACKTRACE=1 cargo unit-test`.
+
+We consider testing critical for anything on a blockchain, and recommend to always keep
+the tests up to date.
+
+## Generating JSON Schema
+
+While the Wasm calls (`instantiate`, `execute`, `query`) accept JSON, this is not enough
+information to use it. We need to expose the schema for the expected messages to the
+clients. You can generate this schema by calling `cargo schema`, which will output
+4 files in `./schema`, corresponding to the 3 message types the contract accepts,
+as well as the internal `State`.
+
+These files are in standard json-schema format, which should be usable by various
+client side tools, either to auto-generate codecs, or just to validate incoming
+json wrt. the defined schema.
+
+## Preparing the Wasm bytecode for production
+
+Before we upload it to a chain, we need to ensure the smallest output size possible,
+as this will be included in the body of a transaction. We also want to have a
+reproducible build process, so third parties can verify that the uploaded Wasm
+code did indeed come from the claimed rust code.
+
+To solve both these issues, we have produced `rust-optimizer`, a docker image to
+produce an extremely small build output in a consistent manner. The suggest way
+to run it is this:
+
+```sh
+docker run --rm -v "$(pwd)":/code \
+  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
+  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
+  cosmwasm/rust-optimizer:0.12.11
+```
+
+Or, If you're on an arm64 machine, you should use a docker image built with arm64.
+```sh
+docker run --rm -v "$(pwd)":/code \
+  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
+  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
+  cosmwasm/rust-optimizer-arm64:0.12.11
+```
+
+We must mount the contract code to `/code`. You can use a absolute path instead
+of `$(pwd)` if you don't want to `cd` to the directory first. The other two
+volumes are nice for speedup. Mounting `/code/target` in particular is useful
+to avoid docker overwriting your local dev files with root permissions.
+Note the `/code/target` cache is unique for each contract being compiled to limit
+interference, while the registry cache is global.
+
+This is rather slow compared to local compilations, especially the first compile
+of a given contract. The use of the two volume caches is very useful to speed up
+following compiles of the same contract.
+
+This produces an `artifacts` directory with a `PROJECT_NAME.wasm`, as well as
+`checksums.txt`, containing the Sha256 hash of the wasm file.
+The wasm file is compiled deterministically (anyone else running the same
+docker on the same git commit should get the identical file with the same Sha256 hash).
+It is also stripped and minimized for upload to a blockchain (we will also
+gzip it in the uploading process to make it even smaller).

+# Importing
+
+In [Publishing](./Publishing.md), we discussed how you can publish your contract to the world.
+This looks at the flip-side, how can you use someone else's contract (which is the same
+question as how they will use your contract). Let's go through the various stages.
+
+## Verifying Artifacts
+
+Before using remote code, you most certainly want to verify it is honest.
+
+The simplest audit of the repo is to simply check that the artifacts in the repo
+are correct. This involves recompiling the claimed source with the claimed builder
+and validating that the locally compiled code (hash) matches the code hash that was
+uploaded. This will verify that the source code is the correct preimage. Which allows
+one to audit the original (Rust) source code, rather than looking at wasm bytecode.
+
+We have a script to do this automatic verification steps that can
+easily be run by many individuals. Please check out
+[`cosmwasm-verify`](https://github.com/CosmWasm/cosmwasm-verify/blob/master/README.md)
+to see a simple shell script that does all these steps and easily allows you to verify
+any uploaded contract.
+
+## Reviewing
+
+Once you have done the quick programatic checks, it is good to give at least a quick
+look through the code. A glance at `examples/schema.rs` to make sure it is outputing
+all relevant structs from `contract.rs`, and also ensure `src/lib.rs` is just the
+default wrapper (nothing funny going on there). After this point, we can dive into
+the contract code itself. Check the flows for the execute methods, any invariants and
+permission checks that should be there, and a reasonable data storage format.
+
+You can dig into the contract as far as you want, but it is important to make sure there
+are no obvious backdoors at least.
+
+## Decentralized Verification
+
+It's not very practical to do a deep code review on every dependency you want to use,
+which is a big reason for the popularity of code audits in the blockchain world. We trust
+some experts review in lieu of doing the work ourselves. But wouldn't it be nice to do this
+in a decentralized manner and peer-review each other's contracts? Bringing in deeper domain
+knowledge and saving fees.
+
+Luckily, there is an amazing project called [crev](https://github.com/crev-dev/cargo-crev/blob/master/cargo-crev/README.md)
+that provides `A cryptographically verifiable code review system for the cargo (Rust) package manager`.
+
+I highly recommend that CosmWasm contract developers get set up with this. At minimum, we
+can all add a review on a package that programmatically checked out that the json schemas
+and wasm bytecode do match the code, and publish our claim, so we don't all rely on some
+central server to say it validated this. As we go on, we can add deeper reviews on standard
+packages.
+
+If you want to use `cargo-crev`, please follow their
+[getting started guide](https://github.com/crev-dev/cargo-crev/blob/master/cargo-crev/src/doc/getting_started.md)
+and once you have made your own *proof repository* with at least one *trust proof*,
+please make a PR to the [`cawesome-wasm`]() repo with a link to your repo and
+some public name or pseudonym that people know you by. This allows people who trust you
+to also reuse your proofs.
+
+There is a [standard list of proof repos](https://github.com/crev-dev/cargo-crev/wiki/List-of-Proof-Repositories)
+with some strong rust developers in there. This may cover dependencies like `serde` and `snafu`
+but will not hit any CosmWasm-related modules, so we look to bootstrap a very focused
+review community.

+# Publishing Contracts
+
+This is an overview of how to publish the contract's source code in this repo.
+We use Cargo's default registry [crates.io](https://crates.io/) for publishing contracts written in Rust.
+
+## Preparation
+
+Ensure the `Cargo.toml` file in the repo is properly configured. In particular, you want to
+choose a name starting with `cw-`, which will help a lot finding CosmWasm contracts when
+searching on crates.io. For the first publication, you will probably want version `0.1.0`.
+If you have tested this on a public net already and/or had an audit on the code,
+you can start with `1.0.0`, but that should imply some level of stability and confidence.
+You will want entries like the following in `Cargo.toml`:
+
+```toml
+name = "cw-escrow"
+version = "0.1.0"
+description = "Simple CosmWasm contract for an escrow with arbiter and timeout"
+repository = "https://github.com/confio/cosmwasm-examples"
+```
+
+You will also want to add a valid [SPDX license statement](https://spdx.org/licenses/),
+so others know the rules for using this crate. You can use any license you wish,
+even a commercial license, but we recommend choosing one of the following, unless you have
+specific requirements.
+
+* Permissive: [`Apache-2.0`](https://spdx.org/licenses/Apache-2.0.html#licenseText) or [`MIT`](https://spdx.org/licenses/MIT.html#licenseText)
+* Copyleft: [`GPL-3.0-or-later`](https://spdx.org/licenses/GPL-3.0-or-later.html#licenseText) or [`AGPL-3.0-or-later`](https://spdx.org/licenses/AGPL-3.0-or-later.html#licenseText)
+* Commercial license: `Commercial` (not sure if this works, I cannot find examples)
+
+It is also helpful to download the LICENSE text (linked to above) and store this
+in a LICENSE file in your repo. Now, you have properly configured your crate for use
+in a larger ecosystem.
+
+### Updating schema
+
+To allow easy use of the contract, we can publish the schema (`schema/*.json`) together
+with the source code.
+
+```sh
+cargo schema
+```
+
+Ensure you check in all the schema files, and make a git commit with the final state.
+This commit will be published and should be tagged. Generally, you will want to
+tag with the version (eg. `v0.1.0`), but in the `cosmwasm-examples` repo, we have
+multiple contracts and label it like `escrow-0.1.0`. Don't forget a
+`git push && git push --tags`
+
+### Note on build results
+
+Build results like Wasm bytecode or expected hash don't need to be updated since
+they don't belong to the source publication. However, they are excluded from packaging
+in `Cargo.toml` which allows you to commit them to your git repository if you like.
+
+```toml
+exclude = ["artifacts"]
+```
+
+A single source code can be built with multiple different optimizers, so
+we should not make any strict assumptions on the tooling that will be used.
+
+## Publishing
+
+Now that your package is properly configured and all artifacts are committed, it
+is time to share it with the world.
+Please refer to the [complete instructions for any questions](https://rurust.github.io/cargo-docs-ru/crates-io.html),
+but I will try to give a quick overview of the happy path here.
+
+### Registry
+
+You will need an account on [crates.io](https://crates.io) to publish a rust crate.
+If you don't have one already, just click on "Log in with GitHub" in the top-right
+to quickly set up a free account. Once inside, click on your username (top-right),
+then "Account Settings". On the bottom, there is a section called "API Access".
+If you don't have this set up already, create a new token and use `cargo login`
+to set it up. This will now authenticate you with the `cargo` cli tool and allow
+you to publish.
+
+### Uploading
+
+Once this is set up, make sure you commit the current state you want to publish.
+Then try `cargo publish --dry-run`. If that works well, review the files that
+will be published via `cargo package --list`. If you are satisfied, you can now
+officially publish it via `cargo publish`.
+
+Congratulations, your package is public to the world.
+
+### Sharing
+
+Once you have published your package, people can now find it by
+[searching for "cw-" on crates.io](https://crates.io/search?q=cw).
+But that isn't exactly the simplest way. To make things easier and help
+keep the ecosystem together, we suggest making a PR to add your package
+to the [`cawesome-wasm`](https://github.com/cosmwasm/cawesome-wasm) list.
+
+### Organizations
+
+Many times you are writing a contract not as a solo developer, but rather as
+part of an organization. You will want to allow colleagues to upload new
+versions of the contract to crates.io when you are on holiday.
+[These instructions show how]() you can set up your crate to allow multiple maintainers.
+
+You can add another owner to the crate by specifying their github user. Note, you will
+now both have complete control of the crate, and they can remove you:
+
+`cargo owner --add ethanfrey`
+
+You can also add an existing github team inside your organization:
+
+`cargo owner --add github:confio:developers`
+
+The team will allow anyone who is currently in the team to publish new versions of the crate.
+And this is automatically updated when you make changes on github. However, it will not allow
+anyone in the team to add or remove other owners.

+# CosmWasm Starter Pack
+
+This is a template to build smart contracts in Rust to run inside a
+[Cosmos SDK](https://github.com/cosmos/cosmos-sdk) module on all chains that enable it.
+To understand the framework better, please read the overview in the
+[cosmwasm repo](https://github.com/CosmWasm/cosmwasm/blob/master/README.md),
+and dig into the [cosmwasm docs](https://www.cosmwasm.com).
+This assumes you understand the theory and just want to get coding.
+
+## Creating a new repo from template
+
+Assuming you have a recent version of Rust and Cargo installed
+(via [rustup](https://rustup.rs/)),
+then the following should get you a new repo to start a contract:
+
+Install [cargo-generate](https://github.com/ashleygwilliams/cargo-generate) and cargo-run-script.
+Unless you did that before, run this line now:
+
+```sh
+cargo install cargo-generate --features vendored-openssl
+cargo install cargo-run-script
+```
+
+Now, use it to create your new contract.
+Go to the folder in which you want to place it and run:
+
+**Latest**
+
+```sh
+cargo generate --git https://github.com/CosmWasm/cw-template.git --name PROJECT_NAME
+```
+
+For cloning minimal code repo:
+
+```sh
+cargo generate --git https://github.com/CosmWasm/cw-template.git --name PROJECT_NAME -d minimal=true
+```
+
+**Older Version**
+
+Pass version as branch flag:
+
+```sh
+cargo generate --git https://github.com/CosmWasm/cw-template.git --branch <version> --name PROJECT_NAME
+```
+
+Example:
+
+```sh
+cargo generate --git https://github.com/CosmWasm/cw-template.git --branch 0.16 --name PROJECT_NAME
+```
+
+You will now have a new folder called `PROJECT_NAME` (I hope you changed that to something else)
+containing a simple working contract and build system that you can customize.
+
+## Create a Repo
+
+After generating, you have a initialized local git repo, but no commits, and no remote.
+Go to a server (eg. github) and create a new upstream repo (called `YOUR-GIT-URL` below).
+Then run the following:
+
+```sh
+# this is needed to create a valid Cargo.lock file (see below)
+cargo check
+git branch -M main
+git add .
+git commit -m 'Initial Commit'
+git remote add origin YOUR-GIT-URL
+git push -u origin main
+```
+
+## CI Support
+
+We have template configurations for both [GitHub Actions](.github/workflows/Basic.yml)
+and [Circle CI](.circleci/config.yml) in the generated project, so you can
+get up and running with CI right away.
+
+One note is that the CI runs all `cargo` commands
+with `--locked` to ensure it uses the exact same versions as you have locally. This also means
+you must have an up-to-date `Cargo.lock` file, which is not auto-generated.
+The first time you set up the project (or after adding any dep), you should ensure the
+`Cargo.lock` file is updated, so the CI will test properly. This can be done simply by
+running `cargo check` or `cargo unit-test`.
+
+## Using your project
+
+Once you have your custom repo, you should check out [Developing](./Developing.md) to explain
+more on how to run tests and develop code. Or go through the
+[online tutorial](https://docs.cosmwasm.com/) to get a better feel
+of how to develop.
+
+[Publishing](./Publishing.md) contains useful information on how to publish your contract
+to the world, once you are ready to deploy it on a running blockchain. And
+[Importing](./Importing.md) contains information about pulling in other contracts or crates
+that have been published.
+
+Please replace this README file with information about your specific project. You can keep
+the `Developing.md` and `Publishing.md` files as useful referenced, but please set some
+proper description in the README.
