This is why many commands for the IC SDK start with the command \"`dfx ..`\" such as `dfx new` or `dfx stop`.\n\n2. **dfxvm** - `dfxvm` is the version manager for `dfx`, i.e. a CLI for selecting and managing installed `dfx` versions.\n\n3. **Canister Development Kit (CDK)** - A CDK is an adapter used by the IC SDK so a programming language has the features needed to create and manage canisters. \nThe IC SDK comes with a few CDKs already installed for you so you can use them in the language of your choice. That is why there is a [Rust CDK](https://github.com/dfinity/cdk-rs), [Python CDK](https://demergent-labs.github.io/kybra/), \n[TypeScript CDK](https://demergent-labs.github.io/azle/), etc... Since CDKs are components used the SDK, some developer choose to use the CDK directly (without the `IC SDK`), \nbut typically are used as part of the whole `IC SDK`.\n\n\n## Getting Started\n\n### Prerequisites \n\n#### Install Rust\n\nTo develop Rust projects, you will need to install Rust in your environment with the command:\n\n```\ncurl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh\n```\n\n#### Install `wasm32-unknown-unknown` target\n\nICP smart contracts are compiled into WebAssembly modules. To support this compilation, install the `wasm32-unknown-unknown` target:\n\n```\nrustup target add wasm32-unknown-unknown\n```\n\n### Installing\n\nYou can install the `IC SDK` a few different ways.\n\n#### via `curl` (recommended)\n\n``` bash\nsh -ci \"$(curl -fsSL https://internetcomputer.org/install.sh)\"\n```\n\nThis command will install a binary compatible with your operating system, and add it to `/usr/local/bin`.\n\n#### via GitHub Releases\n\nFind a release for your architecture [here](https://github.com/dfinity/sdk/releases).\n\n#### in GitHub Action, using [`dfinity/setup-dfx`](https://github.com/dfinity/setup-dfx)\n\n```yml\n    steps:\n    - name: Install dfx\n      uses: dfinity/setup-dfx@main\n```\n\n### Getting Help\n\nOnce the `IC SDK` is installed, get acquainted with its capabilities by entering.\n\n``` bash\ndfx help\n```\n\n## Contributing to the DFINITY SDK\n\nSee our contributing guidelines [here](./CONTRIBUTING.md).\n\n### Building the IC SDK\n\nBuilding the `IC SDK` is very simple:\n\n``` bash\ncargo build\n```\n\n## Release Process\n\n`IC SDK` is released in two steps:\n\n1. Publishing a new `IC SDK` release.\n\n2. Publishing a new `manifest.json` and `install.sh` to instruct the installer\n   to actually download and install the new `IC SDK` release.\n\n### Publishing the IC SDK\n\n1. The release manager makes sure the `dfx` `stable` branch points to the revision\n   that should be released and that the revision is tagged with a version (like\n   `0.5.6`).\n\n2. The\n   [`sdk-release`](https://hydra.dfinity.systems/jobset/dfinity-ci-build/sdk-release#tabs-configuration)\n   jobset on Hydra tracks the `stable` branch and starts evaluating shortly\n   after `stable` advances.\n\n3. As you can see it only has the single job `publish.dfx` which is\n   defined [here](https://github.com/dfinity-lab/sdk/blob/stable/ci/release.nix)\n   in terms of the\n   [`dfx`](https://github.com/dfinity-lab/sdk/blob/stable/publish.nix) job. Note\n   that the `publish.dfx` job only exists when the revision has a\n   proper version tag. This prevents publishing of untagged revisions.\n\n4. Our CD system running at `deployer.dfinity.systems` is configured with the\n   [`publish-sdk-dfx-release`](https://github.com/dfinity-lab/infra/blob/1fe63e06135be206d064a74461f739c4fafec3c7/services/nix/publish-sdk-release.nix#L39:L47)\n   job. It will monitor the aforementioned `publish.dfx` job for\n   new builds, whenever there's a new build it will download the output (the CD\n   script) and execute it.\n\n5. As you can see the script also sends a message to the `#build-notifications`\n   Slack channel so you can see when and if the SDK has been published.\n\n### Publishing `manifest.json` and `install.sh`\n\nAfter the `IC SDK` has been released it's available for download but the install\nscript at https://sdk.dfinity.org/install.sh won't immediately install it. To\nmake sure the installer actually downloads and installs the new `IC SDK` release the\n`manifest.json` file at https://sdk.dfinity.org/manifest.json has to set its\n`tags.latest` field to the new version. The following explains how to do that.\n\n1. Edit the `public/manifest.json` file such that it points to the new `IC SDK`\n   version and make sure this is merged in `master`.\n\n2. Similarly to releasing the `IC SDK` there's a\n   [`install-sh`](https://github.com/dfinity-lab/sdk/blob/stable/publish.nix) job\n   that builds a CD script for publishing the `manifest.json` and `install.sh`\n   to our CDN.\n\n3. This\n   [job](https://hydra.dfinity.systems/job/dfinity-ci-build/sdk/publish.install-sh.x86_64-linux)\n   is built on the `sdk` jobset which tracks the `master` branch.\n\n4. `deployer.dfinity.systems` is configured with the\n   [`publish-sdk-install-sh`](https://github.com/dfinity-lab/infra/blob/1fe63e06135be206d064a74461f739c4fafec3c7/services/nix/publish-sdk-release.nix#L48:L56)\n   job which will monitor the aforementioned `publish.install-sh.x86_64-linux`\n   job for new builds, whenever there's a new build it will download the output\n   (the CD script) and execute it.\n\n\n## Troubleshooting\nThis section provides solutions to problems you might encounter when using the `IC SDK` via `dfx` command line\n\n### Project Reset\n\nThis command will remove the build directory and restart your replica:\n\n``` bash\ndfx stop \u0026\u0026 dfx start --clean --background\n```\n\n### Using Internet Identity Locally\nYou can deploy the Internet Identity canister into your replica alongside your project by cloning https://github.com/dfinity/internet-identity. From the `internet-identity` directory, run the following command:\n\n``` bash\nII_ENV=development dfx deploy --no-wallet --argument '(null)'\n```\n\nThere are more notes at https://github.com/dfinity/internet-identity#running-locally that may be helpful.\n","funding_links":[],"categories":["Client Libraries (Agents)"],"sub_categories":["Rust"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdfinity%2Fsdk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdfinity%2Fsdk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdfinity%2Fsdk/lists"}
