+## System Requirements
+
+- **Linux/macOS**: Ubuntu 20.04+/macOS 12+
+- **RAM**: Minimum 8 GB, recommended 16 GB
+- **Disk space**: Minimum 10 GB free space
+- **Dependencies**: build-essential, curl, git
+
+### Installing Dependencies
+
+#### Ubuntu/Debian
+```bash
+sudo apt update
+sudo apt install build-essential curl git autoconf automake libtool zlib1g-dev pkg-config libssl-dev
+```
+
+#### macOS
+```bash
+xcode-select --install
+brew install automake libtool pkg-config openssl
+```

 ## Components
 
-- `go` - Golang
-- `rust` - Rust toolchain
-- `node` - Node.js runtime
-- `pnpm` - Package manager
-- `solana` - Solana CLI tools
-- `anchor` - Anchor
-- `jq` - JSON processor
-- `keys` - Gnark proving keys
-- `dependencies` - all PNPM deps
-- `redis` - Redis server
+- `go` - Golang (for working with network components)
+- `rust` - Rust toolchain (base programming language)
+- `node` - Node.js runtime (for JavaScript/TypeScript)
+- `pnpm` - Package manager (JavaScript dependency management)
+- `solana` - Solana CLI tools (tools for working with Solana)
+- `anchor` - Anchor (framework for Solana development)
+- `jq` - JSON processor (JSON processing in scripts)
+- `keys` - Gnark proving keys (keys for ZK proofs)
+- `dependencies` - all PNPM deps (JavaScript project dependencies)
+- `redis` - Redis server (for caching and asynchronous task processing)
+
+## Common Issues and Solutions
+
+### General Issues
+
+- **Access errors**: Make sure you have write permissions to the project directory
+- **Disk space**: Check available disk space (especially when using `--full-keys`)
+- **Network errors**: Check your internet connection and package server availability
+
+### Specific Issues
+
+- **Redis**: If you have problems installing Redis, you can install it separately through your package manager:
+  - Ubuntu: `sudo apt install redis-server`
+  - macOS: `brew install redis`
+
+- **Keys**: If key download fails, try running:
+  ```bash
+  ./prover/server/scripts/download_keys.sh
+  ```
+
+- **Node.js**: If you already have Node.js installed but the script doesn't recognize it, try skipping this component:
+  ```bash
+  ./scripts/install.sh --skip-components "node"
+  ```
