From 4ea35558482bc3d44a2cc7ee4225214d295ed8e2 Mon Sep 17 00:00:00 2001 From: Mani Bajpai <103181735+ManiBAJPAI22@users.noreply.github.com> Date: Sat, 16 Aug 2025 03:38:26 +0530 Subject: [PATCH] docs: Add comprehensive setup guide and troubleshooting section MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR significantly improves the developer experience for local Kleros v2 setup by adding missing configuration steps and comprehensive troubleshooting guidance. ## What's Added ### ๐Ÿ”ง Environment Setup Section - **API key requirements**: Step-by-step instructions for Alchemy and WalletConnect setup - **Environment file configuration**: Complete `.env.local` file creation with all required variables - **Alternative configuration methods**: Instructions for updating existing `.env.local.public` ### ๐Ÿ› ๏ธ Comprehensive Troubleshooting Section - **8 common setup issues** with exact error messages and copy-paste solutions: 1. Volta yarn version errors (`volta pin yarn`) 2. Module resolution errors (kleros-app build dependency) 3. Environment variable errors (missing API keys) 4. Graph Node fulltext search errors (schema modification) 5. GraphQL code generation failures (endpoint testing) 6. Docker/Graph Node connection issues (port conflicts) 7. Web frontend loading issues (browser debugging) 8. Simulate task errors (working alternatives) ## Issues Addressed This PR addresses real-world problems that block new contributors: - **Missing environment variables** cause runtime errors with no clear guidance - **Volta configuration issues** prevent yarn commands from working - **Missing build dependencies** cause module resolution failures - **Broken simulation commands** (`simulate:all` task doesn't exist) - **No troubleshooting guidance** when things go wrong - **Port number discrepancies** between docs and actual behavior ## Testing These improvements are based on actual setup experience where each documented issue was encountered and resolved during a fresh repository clone and setup process. ## Impact This change will: - โœ… **Reduce onboarding friction** for new developers - โœ… **Save hours of debugging time** with ready solutions - โœ… **Improve developer experience** with clear, actionable guidance - โœ… **Prevent common setup failures** that discourage contributions ## Breaking Changes None. This is purely additive documentation that enhances the existing setup process without changing any functionality. --- README.md | 140 +++++++++++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 127 insertions(+), 13 deletions(-) diff --git a/README.md b/README.md index 9ff56aaa0..d426b766b 100644 --- a/README.md +++ b/README.md @@ -61,26 +61,63 @@ - on Red Hat Linux: `sudo dnf install jq yq` - on Ubuntu Linux: `sudo snap install jq yq` - on MacOS via [brew](https://brew.sh/): `brew install jq yq` + +### Environment Setup + +**API Keys (Required):** + +- **Alchemy API Key** (for blockchain connectivity) + - Sign up at [alchemy.com](https://www.alchemy.com/) + - Create an app and get your API key + +- **WalletConnect Project ID** (for wallet connections) + - Sign up at [cloud.walletconnect.com](https://cloud.walletconnect.com/) + - Create a project and get your Project ID + +**Environment Configuration** + +- Create a `.env.local` file in `/web` (or update an existing `.env.local.public`): + + ``` + cd web + cat > .env.local << EOF + REACT_APP_CORE_SUBGRAPH=http://localhost:8000/subgraphs/name/kleros/kleros-v2-core-local + REACT_APP_DRT_ARBSEPOLIA_SUBGRAPH=http://localhost:8000/subgraphs/name/kleros/kleros-v2-drt-local + ALCHEMY_API_KEY=your_alchemy_api_key_here + WALLETCONNECT_PROJECT_ID=your_walletconnect_project_id_here + EOF + +``` + +(or update an existing `.env.local.public`): + +``` +sed -i 's/export ALCHEMY_API_KEY=/export ALCHEMY_API_KEY=your_alchemy_api_key_here/' web/.env.local.public +sed -i 's/export WALLETCONNECT_PROJECT_ID=/export WALLETCONNECT_PROJECT_ID=your_walletconnect_project_id_here/' web/.env.local.public +``` ### Install the dependencies ```bash -$ yarn install +yarn install # Foundry libraries -$ git submodule update --init --recursive -j 4 +git submodule update --init --recursive -j 4 + +# If you encounter Volta-related yarn errors, run: +volta pin yarn ``` ### [Hardhat CLI auto-completion](https://hardhat.org/guides/shorthand.html) (optional) ```bash -$ npm i -g hardhat-shorthand +npm i -g hardhat-shorthand -$ hardhat-completion install +hardhat-completion install โœ” Which Shell do you use ? ยท bash โœ” We will install completion to ~/.bashrc, is it ok ?
