 # Usage
 
+![Aikido Safe Chain demo](https://raw.githubusercontent.com/AikidoSec/safe-chain/main/docs/safe-package-manager-demo.gif)
+
 ## Installation
 
-Installing the Aikido Safe Chain is easy. You just need 3 simple steps:
+Installing the Aikido Safe Chain is easy with our one-line installer.
+
+### Unix/Linux/macOS
 
-1. **Install the Aikido Safe Chain package globally** using npm:
 ```shell
-   npm install -g @aikidosec/safe-chain
+curl -fsSL https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.sh | sh
 ```
-2. **Setup the shell integration** by running:
+
+### Windows (PowerShell)
+
+```powershell
+iex (iwr "https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.ps1" -UseBasicParsing)
+```
+
+### Pinning to a specific version
+
+To install a specific version instead of the latest, replace `latest` with the version number in the URL (available from version 1.3.2 onwards):
+
+**Unix/Linux/macOS:**
+
 ```shell
-   safe-chain setup
+curl -fsSL https://github.com/AikidoSec/safe-chain/releases/download/x.x.x/install-safe-chain.sh | sh
 ```
-3. **❗Restart your terminal** to start using the Aikido Safe Chain.
+
-   - This step is crucial as it ensures that the shell aliases for npm, npx, yarn, pnpm and pnpx are loaded correctly. If you do not restart your terminal, the aliases will not be available.
+**Windows (PowerShell):**
-4. **Verify the installation** by running:
+
+```powershell
+iex (iwr "https://github.com/AikidoSec/safe-chain/releases/download/x.x.x/install-safe-chain.ps1" -UseBasicParsing)
+```
+
+You can find all available versions on the [releases page](https://github.com/AikidoSec/safe-chain/releases).
+
+### Verify the installation
+
+1. **❗Restart your terminal** to start using the Aikido Safe Chain.
+   - This step is crucial as it ensures that the shell aliases for npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, pip, pip3, poetry, uv, uvx, pipx and pdm are loaded correctly. If you do not restart your terminal, the aliases will not be available.
+
+2. **Verify the installation** by running the verification command:
+
+   ```shell
+   npm safe-chain-verify
+   pnpm safe-chain-verify
+   pip safe-chain-verify
+   uv safe-chain-verify
+
+   # Any other supported package manager: {packagemanager} safe-chain-verify
+   ```
+
+   - The output should display "OK: Safe-chain works!" confirming that Aikido Safe Chain is properly installed and running.
+
+3. **(Optional) Test malware blocking** by attempting to install a test package:
+
+   For JavaScript/Node.js:
+
    ```shell
    npm install safe-chain-test
    ```
-   - The output should show that Aikido Safe Chain is blocking the installation of this package as it is flagged as malware.
 
-When running `npm`, `npx`, `yarn`, `pnpm` or `pnpx` commands, the Aikido Safe Chain will automatically check for malware in the packages you are trying to install. If any malware is detected, it will prompt you to exit the command.
+   For Python:
+
+   ```shell
+   pip3 install safe-chain-pi-test
+   ```
+
+   - The output should show that Aikido Safe Chain is blocking the installation of these test packages as they are flagged as malware.
+
+When running `npm`, `npx`, `yarn`, `pnpm`, `pnpx`, `rush`, `rushx`, `bun`, `bunx`, `pip`, `pip3`, `uv`, `uvx`, `poetry`, `pipx` and `pdm` commands, the Aikido Safe Chain will automatically check for malware in the packages you are trying to install. It also intercepts Python module invocations for pip when available (e.g., `python -m pip install ...`, `python3 -m pip download ...`). If any malware is detected, it will prompt you to exit the command.
+
+You can check the installed version by running:
+
+```shell
+safe-chain --version
+```
 
 ## How it works
 
-The Aikido Safe Chain works by intercepting the npm, npx, yarn, pnpm and pnpx commands and verifying the packages against **[Aikido Intel - Open Sources Threat Intelligence](https://intel.aikido.dev/?tab=malware)**.
+### Malware Blocking
 
-The Aikido Safe Chain integrates with your shell to provide a seamless experience when using npm, npx, yarn, pnpm and pnpx commands. It sets up aliases for these commands so that they are wrapped by the Aikido Safe Chain commands, which perform malware checks before executing the original commands. We currently support:
+The Aikido Safe Chain works by running a lightweight proxy server that intercepts package downloads from the npm registry and PyPI. When you run npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, pip, pip3, uv, uvx, poetry, pipx or pdm commands, all package downloads are routed through this local proxy, which verifies packages in real-time against **[Aikido Intel - Open Sources Threat Intelligence](https://intel.aikido.dev/?tab=malware)**. If malware is detected in any package (including deep dependencies), the proxy blocks the download before the malicious code reaches your machine.
+
+### Minimum package age
+
+Safe Chain applies minimum package age checks to supported ecosystems.
+
+Current enforcement differs by ecosystem:
+
+- npm-based package managers:
+  - during normal package resolution, Safe Chain suppresses versions that are newer than the configured minimum age from the package metadata returned by the registry
+  - for direct package download requests that bypass that metadata flow, Safe Chain can block the request itself using a cached list of newly released packages
+- Python package managers:
+  - during package resolution, Safe Chain suppresses too-young files and releases from PyPI metadata responses
+  - for direct package download requests that bypass that metadata flow, Safe Chain can block the request itself using a cached list of newly released packages
+
+By default, the minimum package age is 48 hours. This provides an additional security layer during the critical period when newly published packages are most vulnerable to containing undetected threats. You can configure this threshold or bypass this protection entirely - see the [Minimum Package Age Configuration](#minimum-package-age) section below.
+
+### Shell Integration
+
+The Aikido Safe Chain integrates with your shell to provide a seamless experience when using npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, and Python package managers (pip, uv, uvx, poetry, pipx, pdm). It sets up aliases for these commands so that they are wrapped by the Aikido Safe Chain commands, which manage the proxy server before executing the original commands. We currently support:

 # Configuration
 
-## Malware Action
+## Logging
 
-You can control how Aikido Safe Chain responds when malware is detected using the `--safe-chain-malware-action` flag:
+You can control the output from Aikido Safe Chain using the `--safe-chain-logging` flag or the `SAFE_CHAIN_LOGGING` environment variable.
 
-- `--safe-chain-malware-action=block` (**default**) - Automatically blocks installation and exits with an error when malware is detected
+### Configuration Options
-- `--safe-chain-malware-action=prompt` - Prompts the user to decide whether to continue despite the malware detection
 
-Example usage:
+You can set the logging level through multiple sources (in order of priority):
+
+1. **CLI Argument** (highest priority):
+   - `--safe-chain-logging=silent` - Suppresses all Aikido Safe Chain output except when malware is blocked. The package manager output is written to stdout as normal, and Safe Chain only writes a short message if it has blocked malware and causes the process to exit.
 
      ```shell
-npm install suspicious-package --safe-chain-malware-action=prompt
+     npm install express --safe-chain-logging=silent
+     ```
+
+   - `--safe-chain-logging=verbose` - Enables detailed diagnostic output from Aikido Safe Chain. Useful for troubleshooting issues or understanding what Safe Chain is doing behind the scenes.
+
+     ```shell
+     npm install express --safe-chain-logging=verbose
+     ```
+
+2. **Environment Variable**:
+
+   ```shell
+   export SAFE_CHAIN_LOGGING=verbose
+   npm install express
+   ```
+
+   Valid values: `silent`, `normal`, `verbose`
+
+   This is useful for setting a default logging level for all package manager commands in your terminal session or CI/CD environment.
+
+## Minimum Package Age
+
+You can configure how long packages must exist before Safe Chain allows their installation. By default, packages must be at least 48 hours old before they can be installed.
+
+For npm-based package managers, this check currently has two enforcement modes:
+
+- Safe Chain suppresses too-young versions from package metadata during normal dependency resolution.
+- Safe Chain blocks direct package download requests when they are matched against the cached newly released packages list.
+
+For Python package managers, this check currently has two enforcement modes:
+
+- Safe Chain suppresses too-young files and releases from PyPI metadata during dependency resolution.
+- Safe Chain blocks direct package download requests when they are matched against the cached newly released packages list.
+
+### Configuration Options
+
+You can set the minimum package age through multiple sources (in order of priority):
+
+1. **CLI Argument** (highest priority):
+
+   ```shell
+   npm install express --safe-chain-minimum-package-age-hours=48
+   ```
+
+2. **Environment Variable**:
+
+   ```shell
+   export SAFE_CHAIN_MINIMUM_PACKAGE_AGE_HOURS=48
+   npm install express
+   ```
+
+3. **Config File** (`~/.safe-chain/config.json`):
+
+   ```json
+   {
+     "minimumPackageAgeHours": 48
+   }
+   ```
+
+### Excluding Packages
+
+Exclude trusted packages from minimum age filtering via environment variable or config file (both are merged). Use `@scope/*` to trust all packages from an organization:
+
+```shell
+export SAFE_CHAIN_MINIMUM_PACKAGE_AGE_EXCLUSIONS="@aikidosec/*"
+```
+
+```json
+{
+  "npm": {
+    "minimumPackageAgeExclusions": ["@aikidosec/*"]
+  },
+  "pip": {
+    "minimumPackageAgeExclusions": ["requests"]
+  }
+}
+```
+
+## Custom Registries
+
+Configure Safe Chain to scan packages from custom or private registries.
+
+Supported ecosystems:
+
+- Node.js
+- Python
+
+### Configuration Options
+
+You can set custom registries through environment variable or config file. Both sources are merged together.
+
+1. **Environment Variable** (comma-separated):
+
+   ```shell
+   export SAFE_CHAIN_NPM_CUSTOM_REGISTRIES="npm.company.com,registry.internal.net"
+   export SAFE_CHAIN_PIP_CUSTOM_REGISTRIES="pip.company.com,registry.internal.net"
+   ```
+
+2. **Config File** (`~/.safe-chain/config.json`):
+
+   ```json
+   {
+     "npm": {
+       "customRegistries": ["npm.company.com", "registry.internal.net"]
+     },
+     "pip": {
+       "customRegistries": ["pip.company.com", "registry.internal.net"]
+     }
+   }
+   ```
+
+## PYPI Configuration File
+
+If you rely on a `pip.conf` file for pip configuration you must point pip at it explicitly via the `PIP_CONFIG_FILE` environment variable so Safe Chain can merge it.
+
+Safe Chain runs pip behind its MITM proxy and writes a temporary pip configuration file to inject its certificate and proxy settings. When `PIP_CONFIG_FILE` is set, Safe Chain merges its settings into a copy of your file (your original file is never modified) so your `index-url`, credentials, and other options are preserved. When `PIP_CONFIG_FILE` is not set, pip's user-level config (e.g. `~/.config/pip/pip.conf`) might be overridden by Safe Chain's temporary file and your settings will not be picked up.
+
+## Malware List Base URL
+
+Configure Safe Chain to fetch malware databases and new packages lists from a custom mirror URL. This allows you to host your own copy of the Aikido malware database.
+
+### Configuration Options
+
+You can set the malware list base URL through multiple sources (in order of priority):
+
+1. **CLI Argument** (highest priority):
+
+   ```shell
+   npm install express --safe-chain-malware-list-base-url=https://your-mirror.com
+   ```
+
+2. **Environment Variable**:
+
+   ```shell
+   export SAFE_CHAIN_MALWARE_LIST_BASE_URL=https://your-mirror.com
+   npm install express
+   ```
+
+3. **Config File** (`~/.safe-chain/config.json`):
+
+   ```json
+   {
+     "malwareListBaseUrl": "https://your-mirror.com"
+   }
+   ```
+
+The base URL should point to a server that mirrors the structure of `https://malware-list.aikido.dev/`, including the following paths:
+- `/malware_predictions.json` (JavaScript ecosystem malware database)
+- `/malware_pypi.json` (Python ecosystem malware database)
+- `/releases/npm.json` (JavaScript new packages list)
+- `/releases/pypi.json` (Python new packages list)
+
+## Custom Install Directory
+
+By default, Safe Chain installs itself into `~/.safe-chain`. You can change this by passing an explicit install directory to the installer. This is useful for system-wide installations (e.g. inside a Docker image) or when you need to avoid conflicts with other tools.
+
+When set, all Safe Chain data (binary, shims, scripts, config) is placed under the custom directory instead of `~/.safe-chain`.
+
+### Unix/Linux/macOS
+
+```shell
+curl -fsSL https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.sh | sh -s -- --install-dir /usr/local/.safe-chain
+```
+
+### Windows
+
+```powershell
+iex "& { $(iwr 'https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.ps1' -UseBasicParsing) } -InstallDir 'C:\ProgramData\safe-chain'"
 ```
 
 # Usage in CI/CD
 
-🚧 Support for CI/CD environments is coming soon...
+You can protect your CI/CD pipelines from malicious packages by integrating Aikido Safe Chain into your build process. This ensures that any packages installed during your automated builds are checked for malware before installation.
+
+## Installation for CI/CD
+
+Use the `--ci` flag to automatically configure Aikido Safe Chain for CI/CD environments. This sets up executable shims in the PATH instead of shell aliases.
+
+### Unix/Linux/macOS (GitHub Actions, Azure Pipelines, etc.)

+    stage('Install project dependencies etc...') {
+      steps {
+        sh '''
+          set -euo pipefail
+          npm ci
+        '''
+      }
+    }
+  }
+}

+
+## Bitbucket Pipelines Example
+
+```yaml
+image: node:22
+
+steps:
+  - step:
+      name: Install
+      script:
+        - curl -fsSL https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.sh | sh -s -- --ci
+        - export PATH=~/.safe-chain/shims:~/.safe-chain/bin:$PATH
+        - npm ci
+```
+
+After setup, all subsequent package manager commands in your CI pipeline will automatically be protected by Aikido Safe Chain's malware detection.
+
+## GitLab Pipelines Example
+
+To add safe-chain in GitLab pipelines, you need to install it in the image running the pipeline. This can be done by:
+
+1. Define a dockerfile to run your build
+
+   ```dockerfile
+   FROM node:lts
+
+   # Install safe-chain
+   RUN curl -fsSL https://github.com/AikidoSec/safe-chain/releases/latest/download/install-safe-chain.sh | sh -s -- --ci
+
+   # Add safe-chain to PATH (update paths if you used a custom install dir)
+   ENV PATH="/root/.safe-chain/shims:/root/.safe-chain/bin:${PATH}"
+   ```
+
+2. Build the Docker image in your CI pipeline
+
+   ```yaml
+   build-image:
+     stage: build-image
+     image: docker:latest
+     services:
+       - docker:dind
+     script:
+       - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
+       - docker build -t $CI_REGISTRY_IMAGE:latest .
+       - docker push $CI_REGISTRY_IMAGE:latest
+   ```
+
+3. Use the image in your pipeline:
+   ```yaml
+   npm-ci:
+     stage: install
+     image: $CI_REGISTRY_IMAGE:latest
+     script:
+       - npm ci
+   ```
+
+The full pipeline for this example looks like this:
+
+```yaml
+stages:
+  - build-image
+  - install
+
+build-image:
+  stage: build-image
+  image: docker:latest
+  services:
+    - docker:dind
+  script:
+    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
+    - docker build -t $CI_REGISTRY_IMAGE:latest .
+    - docker push $CI_REGISTRY_IMAGE:latest
+
+npm-ci:
+  stage: install
+  image: $CI_REGISTRY_IMAGE:latest
+  script:
+    - npm ci
+```

+### 1. Create and push a version tag
+
+```bash
+git tag 1.0.0
+git push origin 1.0.0
+```
+
+This triggers the build pipeline, which compiles binaries for all platforms and creates a draft GitHub release.
+
+### 2. Wait for artifacts to build
+
+Monitor the [Actions tab](https://github.com/AikidoSec/safe-chain/actions) until the `Create Release` workflow completes.
+
+### 3. Publish the GitHub release
+
+1. Go to the [Releases page](https://github.com/AikidoSec/safe-chain/releases)
+2. Open the draft release created for your tag
+3. Add release notes
+4. Click **Publish release**
+
+Publishing the release automatically triggers an npm publish. Pre-release versions (e.g. `1.0.0-beta`) are published to npm under a tag matching the pre-release identifier (e.g. `beta`). Stable versions are published to the `latest` tag.

+The shell integration automatically wraps common package manager commands (`npm`, `npx`, `yarn`, `pnpm`, `pnpx`, `rush`, `rushx`, `bun`, `bunx`, `pip`, `pip3`, `uv`, `uvx`, `poetry`, `pipx`) with Aikido's security scanning functionality. It also intercepts Python module invocations for pip when available: `python -m pip`, `python -m pip3`, `python3 -m pip`, `python3 -m pip3`. This is achieved by sourcing startup scripts that define shell functions to wrap these commands with their Aikido-protected equivalents.

+   Edit the same startup file from step 1 and delete any lines that source Safe Chain scripts from `~/.safe-chain/scripts/`.
+
+## Manual Setup
+
+For advanced users who prefer manual configuration, you can create wrapper functions directly in your shell's startup file. Shell functions take precedence over commands in PATH, so defining an `npm` function will intercept all `npm` calls:
+
+```bash
+# Example for Bash/Zsh
+npm() {
+  if command -v aikido-npm > /dev/null 2>&1; then
+    aikido-npm "$@"
+  else
+    echo "Warning: safe-chain is not installed. npm will run without protection."
+    command npm "$@"
+  fi
+}
+```
+
+Repeat this pattern for `npx`, `yarn`, `pnpm`, `pnpx`, `rush`, `rushx`, `bun`, `bunx`, `pip`, `pip3`, `uv`, `uvx`, `poetry` and `pipx` using their respective `aikido-*` commands. After adding these functions, restart your terminal to apply the changes.
+
+To intercept Python module invocations for pip without altering Python itself, you can add small forwarding functions:
+
+```bash
+# Example for Bash/Zsh
+python() {
+  if [[ "$1" == "-m" && "$2" == pip* ]]; then
+    local mod="$2"; shift 2
+    if [[ "$mod" == "pip3" ]]; then aikido-pip3 "$@"; else aikido-pip "$@"; fi
+  else
+    command python "$@"
+  fi
+}
+
+python3() {
+  if [[ "$1" == "-m" && "$2" == pip* ]]; then
+    local mod="$2"; shift 2
+    if [[ "$mod" == "pip3" ]]; then aikido-pip3 "$@"; else aikido-pip "$@"; fi
+  else
+    command python3 "$@"
+  fi
+}
+```
+
+Limitations: these only apply when invoking `python`/`python3` by name. Absolute paths (e.g., `/usr/bin/python -m pip`) bypass shell functions.

+# Troubleshooting
+
+This guide helps you diagnose and resolve common issues with Aikido Safe Chain.
+
+## Verification & Diagnostics
+
+**Check Installation**
+
+```bash
+# Check version
+safe-chain --version
+```
+
+**Verify Shell Integration**
+
+Run the verification command for your package manager:
+
+```bash
+npm safe-chain-verify
+pnpm safe-chain-verify
+```
+
+```
+Expected output: `OK: Safe-chain works!`
+```
+
+**Test Malware Blocking**
+
+Verify that malware detection is working:
+```
+npm install safe-chain-test
+```
+
+These test packages are flagged as malware and should be blocked by Safe Chain.
+
+**If the test package installs successfully instead of being blocked**, see Malware Not Being Blocked below.
+
+## Logging Options
+
+Use logging flags or environment variables to get more information:
+
+```bash
+# Verbose mode - detailed diagnostic output for troubleshooting
+npm install express --safe-chain-logging=verbose
+
+# Or set it globally for all commands in your session
+export SAFE_CHAIN_LOGGING=verbose
+npm install express
+
+# Silent mode - suppress all output except malware blocking
+npm install express --safe-chain-logging=silent
+```
+
+## Common Issues
+
+### Malware Not Being Blocked
+
+**Symptom:** Test malware packages (like `safe-chain-test`) install successfully when they should be blocked
+
+**Most Common Cause:** The package is cached in your package manager's local store
+
+Safe-chain blocks malicious packages by intercepting network requests to package registries using its proxy.
+
+When a package is already cached locally, the package manager skips downloading it from the registry, which bypasses the proxy.
+
+**Resolution Steps**
+
+1) Clear your package manager's cache
+
+```bash
+# For npm
+npm cache clean --force
+
+# For pnpm
+pnpm store prune
+
+# For yarn (classic)
+yarn cache clean
+
+# For yarn (berry/v2+)
+yarn cache clean --all
+
+# For bun
+bun pm cache rm
+```
+
+2) Clean local installation artifacts:
+
+```bash
+# Remove node_modules if you want a completely fresh install
+rm -rf node_modules
+```
+
+3) Re-test malware blocking:
+
+```bash
+npm install safe-chain-test    # Should be blocked
+```
+
+### Shell Aliases Not Working After Installation
+
+**Symptom:** Running `npm` shows regular npm instead of safe-chain wrapped version
+
+**First step:** Restart your terminal (most common fix)
+
+**Verify it's working:**
+
+```bash
+type npm
+```
+
+Should show: `npm is a function`
+
+**If still not working:**
+
+Check that your startup file sources safe-chain scripts from `~/.safe-chain/scripts/`:
+
+* Bash: `~/.bashrc`
+* Zsh: `~/.zshrc`
+* Fish: `~/.config/fish/config.fish`
+* PowerShell: `$PROFILE`
+
+### "Command Not Found: safe-chain"
+
+**Symptom:** Binary not found in PATH
+
+**First step:** Restart your terminal
+
+**Check PATH:**
+
+```bash
+echo $PATH
+```
+
+Should include `~/.safe-chain/bin`
+
+**If persists:** Re-run the installation script
+
+### PowerShell Execution Policy Blocks Scripts (Windows)
+
+**Symptom:** When opening PowerShell, you see an error like:
+
+```
+. : File C:\Users\<username>\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 cannot be loaded because
+running scripts is disabled on this system.
+CategoryInfo          : SecurityError: (:) [], PSSecurityException
+FullyQualifiedErrorId : UnauthorizedAccess
+```
+
+**Cause:** Windows PowerShell's default execution policy (`Restricted`) blocks all script execution, including safe-chain's initialization script that's sourced from your PowerShell profile.
+
+**Resolution**
+
+1) Set the execution policy to allow local scripts
+
+Open PowerShell as Administrator and run:
+
+```powershell
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
+```
+
+This allows:
+
+* Local scripts (like safe-chain's) to run without signing
+* Downloaded scripts to run only if signed by a trusted publisher
+
+2) Restart PowerShell and verify the error is resolved.
+
+> [!IMPORTANT]
+> `RemoteSigned` is Microsoft's recommended execution policy for client computers. It provides a good balance between security and usability.
+
+### Shell Aliases Persist After Uninstallation
+
+**Symptom:** safe-chain commands still active after running uninstall script
+
+**Steps**
+
+1. Run `safe-chain teardown` (if binary still exists)
+2. Restart your terminal
+3. If still present, manually edit shell config files:
+   * Bash: `~/.bashrc`
+   * Zsh: `~/.zshrc`
+   * Fish: `~/.config/fish/config.fish`
+   * PowerShell: `$PROFILE`
+4. Remove lines that source scripts from `~/.safe-chain/scripts/`
+5. Restart terminal again
+
+## Manual Verification Steps
+
+### Check Installation Status
+
+```bash
+# Check installation location (helps identify if installed via npm or as standalone binary)
+which safe-chain
+
+# Verify binary exists
+ls ~/.safe-chain/bin/safe-chain
+
+# Check version
+safe-chain --version
+
+# Test shell integration
+type npm
+type pip
+```
+
+**Expected `which` output:**
+
+* Standalone binary (correct): `~/.safe-chain/bin/safe-chain` or `/Users/<username>/.safe-chain/bin/safe-chain`
+* npm global (outdated): path containing `node_modules` or nvm version paths
+
+If `which` shows an npm installation, see Check for Conflicting Installations.
+
+### Check Shell Integration
+
+```bash
+# Which shell you're using
+echo $SHELL
+
+# Check if startup file sources safe-chain
+# For Bash:
+grep safe-chain ~/.bashrc
+
+# For Zsh:
+grep safe-chain ~/.zshrc
+
+# For Fish:
+grep safe-chain ~/.config/fish/config.fish
+
+# Verify scripts exist
+ls ~/.safe-chain/scripts/
+```
+
+### Check for Conflicting Installations
+
+> **Note:** The install/uninstall scripts automatically detect and remove conflicting installations, but you can manually check:
+
+```bash
+# Check npm global
+npm list -g @aikidosec/safe-chain
+
+# Check Volta
+volta list safe-chain
+
+# Check nvm (all versions)
+for version in $(nvm list | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+'); do
+  nvm exec "$version" npm list -g @aikidosec/safe-chain 2>/dev/null && echo "Found in $version"
+done
+```
+
+### Manual Cleanup
+
+> **Note:** The install and uninstall scripts automatically handle these cleanup steps. Use these manual commands only if automatic cleanup fails.
+
+#### Remove npm Global Installation
+
+```bash
+npm uninstall -g @aikidosec/safe-chain
+```
+
+#### Remove Volta Installation
+
+```bash
+volta uninstall @aikidosec/safe-chain
+```
+
+#### Remove nvm Installations (All Versions)
+
+```bash
+# Automated approach
+for version in $(nvm list | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+'); do
+  nvm exec "$version" npm uninstall -g @aikidosec/safe-chain
+done
+
