-## 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.

-

-## Steps
-
-### 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.
