 # Release Process
 
-## 1. Draft the release
+## 1. Refresh the CocoaPods trunk token
+
+> [!IMPORTANT]
+> The `COCOAPODS_TRUNK_TOKEN` secret in this repository expires after ~3 days. **Refresh it before every release.**
+
+1. Generate a new session token:
+   ```bash
+   pod trunk register developers@mparticle.com 'mParticle Developers' --description='CI release'
+   ```
+   Confirm via the email link, then retrieve the token:
+   ```bash
+   grep -A2 'trunk.cocoapods.org' ~/.netrc | grep password | awk '{print $2}'
+   ```
+2. Update the `COCOAPODS_TRUNK_TOKEN` secret in **Settings → Secrets and variables → Actions** on this repository.
+
+## 2. Draft the release
 
 1. Go to **Actions → Release – Draft** in GitHub
 2. Select the bump type (`patch`, `minor`, or `major`) and run the workflow from `main`
 
 This bumps versions across podspecs, `Package.swift`, constants files, and `CHANGELOG.md`, then opens a release PR against `main`.
 
-## 2. Merge the release PR
+## 3. Merge the release PR
 
 Review and merge the PR. On merge, the **Release – Publish** workflow runs automatically:
 
 - Builds xcframeworks for every kit
 - Mirrors each kit subtree to its own repo under `mparticle-integrations/`
 - Creates GitHub releases and tags (used by SPM consumers)
-
-## 3. Publish to CocoaPods
-
-> [!IMPORTANT]
-> This is a **manual** step. Wait for the Release – Publish workflow to finish before running — kit mirror repos and GitHub tags must exist first.
-
-```bash
-# Register a trunk session if you don't have one (expires after ~3 days):
-pod trunk register developers@mparticle.com 'mParticle Developers' --description='<your machine>'
-# (confirm via email link)
-
-# Publish everything:
-./Scripts/pod_publish.sh
-```
-
-This pushes the Swift SDK and core SDK podspecs sequentially, then all kit podspecs in parallel.
+- Publishes the core SDK and all kit podspecs to CocoaPods trunk
+
+> [!NOTE]
+> The Swift SDK podspec (`mParticle-Apple-SDK-Swift`) is not yet published automatically — push it manually before the core SDK if required:
+>
+> ```bash
+> pod trunk push mParticle-Apple-SDK-Swift/mParticle-Apple-SDK-Swift.podspec --allow-warnings
+> ```
