source, there are different ways you can contribute, all\nof which are valuable. Here's few guidelines that should help you as you prepare\nyour contribution.\n\n## Initial steps\n\nBefore you start working on a contribution, create an issue describing what you want to build. It's possible someone else is already working on something similar, or perhaps there is a reason that feature isn't implemented. The maintainers will point you in the right direction.\n\n<!-- ## Submitting a Pull Request\n\n- Fork the repo\n- Clone your forked repository: `git clone git@github.com:{your_username}/zod.git`\n- Enter the zod directory: `cd zod`\n- Create a new branch off the `master` branch: `git checkout -b your-feature-name`\n- Implement your contributions (see the Development section for more information)\n- Push your branch to the repo: `git push origin your-feature-name`\n- Go to https://github.com/colinhacks/zod/compare and select the branch you just pushed in the \"compare:\" dropdown\n- Submit the PR. The maintainers will follow up ASAP. -->\n\n## Development\n\nThe following steps will get you setup to contribute changes to this repo:\n\n1. Fork this repo.\n\n2. Clone your forked repo: `git clone git@github.com:{your_username}/zod.git`\n\n3. Run `pnpm i` to install dependencies.\n\n4. Start playing with the code! You can do some simple experimentation in [`play.ts`](play.ts) (see `pnpm play` below) or start implementing a feature right away.\n\n\n## Alternative: VSCode Dev Container setup\n\nFor an officially supported isolated dev environment that automatically installs dependencies for you:\n\n1. `F1` in VSCode and start typing `Dev Containers: Clone Repository in Named Container Volume` to run the command.\n2. For the repo, paste `git@github.com:{your_username}/zod.git` if you're using ssh.\n3. Click `Create a new volume...` and name it `zod` and the folder name as `zod`.\n\nNote: if you can't see `Dev Containers` in the `F1` menu, follow [this guide](https://code.visualst\n\nFile: LICENSE\nMIT License\n\nCopyright (c) 2025 Colin McDonnell\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

citation.\n- Citation fields required: path, side, start_line, end_line, anchor_kind, head_sha.\n- Use side in {\"new\",\"old\",\"context\"} and anchor_kind in {\"diff\",\"file\"}.\n- start_line and

source, there are different ways you can contribute, all\nof which are valuable. Here's few guidelines that should help you as you prepare\nyour contribution.\n\n## Initial steps\n\nBefore you start working on a contribution, create an issue describing what you want to build. It's possible someone else is already working on something similar, or perhaps there is a reason that feature isn't implemented. The maintainers will point you in the right direction.\n\n<!-- ## Submitting a Pull Request\n\n- Fork the repo\n- Clone your forked repository: `git clone git@github.com:{your_username}/zod.git`\n- Enter the zod directory: `cd zod`\n- Create a new branch off the `master` branch: `git checkout -b your-feature-name`\n- Implement your contributions (see the Development section for more information)\n- Push your branch to the repo: `git push origin your-feature-name`\n- Go to https://github.com/colinhacks/zod/compare and select the branch you just pushed in the \"compare:\" dropdown\n- Submit the PR. The maintainers will follow up ASAP. -->\n\n## Development\n\nThe following steps will get you setup to contribute changes to this repo:\n\n1. Fork this repo.\n\n2. Clone your forked repo: `git clone git@github.com:{your_username}/zod.git`\n\n3. Run `pnpm i` to install dependencies.\n\n4. Start playing with the code! You can do some simple experimentation in [`play.ts`](play.ts) (see `pnpm play` below) or start implementing a feature right away.\n\n\n## Alternative: VSCode Dev Container setup\n\nFor an officially supported isolated dev environment that automatically installs dependencies for you:\n\n1. `F1` in VSCode and start typing `Dev Containers: Clone Repository in Named Container Volume` to run the command.\n2. For the repo, paste `git@github.com:{your_username}/zod.git` if you're using ssh.\n3. Click `Create a new volume...` and name it `zod` and the folder name as `zod`.\n\nNote: if you can't see `Dev Containers` in the `F1` menu, follow [this guide](https://code.visualst\n\nFile: LICENSE\nMIT License\n\nCopyright (c) 2025 Colin McDonnell\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
