Generate technical documentation with AI

Implement with AI

Send this guide to your coding agent.

Prerequisite: Install Port MCP

A lot of repositories never grow a real explanation of how they work. The README covers how to start the app, the architecture lives in someone's head, and the person who built the tricky part has moved on. New teammates stall on the same question coding agents do: where do I start?

Manage and surface technical documentation can put markdown next to a service in Port, but only when that markdown already exists. This guide covers the gap. From a repository in Port, you ask Claude Code to read the code and write a wiki: an overview, the architecture, the modules, and the APIs. You review it in a pull request, the same way you review any other change. After you merge it, the pages show up in Port's catalog, and they stay current as the code moves.

Common use cases

• Give a repository its first real docs when the code is the only source of truth.
• Keep the wiki honest by refreshing the pages a merge actually affected, instead of rewriting the whole thing.
• Keep a person in the loop so documentation lands through review, not a silent commit to the default branch.

How it works

Someone opens a repository in Port and runs Generate wiki. The self-service trigger collects the repository and whether this is the first wiki or a refresh, and a GitHub action hands the job to one backend repository. Claude Code reads the code, writes the wiki under docs/wiki/, leaves the application alone, and opens a pull request for a person to merge. After the merge, those pages become tech docs, and the TechDocs plugin on the wiki dashboard shows them next to the generations still waiting for review.

About once an hour, the backend looks for code that landed since the wiki was last updated and opens a smaller pull request for the affected pages. A marker in the wiki records the commit the pages describe and moves only when you merge, so closing a pull request means the next pass picks up the same changes again.

Prerequisites

This guide assumes the following:

• You have a Port account and have completed the onboarding process.
• Port's GitHub Ocean integration is installed and ingesting repositories into the githubRepository blueprint.
• You can create a repository in your GitHub organization and manage fine-grained personal access tokens.
• You have an Anthropic API key.
• You have a Port API client ID and secret. See find your Port credentials.

Set up the data model

Port needs two places to put what GitHub is about to produce. techDoc is each page of the wiki, linked to the repository it describes. wikiRun is a short log of each generation: which repository, whether a pull request opened, and a link back to the run. The dashboard later uses that log to show what is waiting on a person.

New blueprint

Create the techDoc blueprint

techDoc relates each page to the repository that contains it. The TechDocs plugin uses that relation to scope the page list.

1. Go to the Data model page in Port.

2. Click + Blueprint.

3. Click the {...} Edit JSON button.

4. Copy and paste the following JSON configuration:

   Tech Doc blueprint (click to expand)

   {
     "identifier": "techDoc",
     "title": "Tech Doc",
     "icon": "Book",
     "schema": {
       "properties": {
         "content": {
           "title": "Content",
           "type": "string",
           "format": "markdown",
           "description": "The raw markdown content of the document"
         },
         "filePath": {
           "title": "File Path",
           "type": "string",
           "description": "Path to the file within the repository"
         },
         "folderPath": {
           "title": "Folder Path",
           "type": "string",
           "description": "Parent folder path (e.g. docs/wiki)"
         },
         "url": {
           "title": "URL",
           "type": "string",
           "format": "url",
           "description": "Direct link to the file in the repository"
         },
         "lastUpdated": {
           "title": "Last Updated",
           "type": "string",
           "format": "date-time"
         },
         "archived": {
           "type": "boolean",
           "title": "Archived",
           "default": false
         }
       },
       "required": [
         "content"
       ]
     },
     "mirrorProperties": {},
     "calculationProperties": {},
     "aggregationProperties": {},
     "relations": {
       "repository": {
         "title": "Repository",
         "target": "githubRepository",
         "required": true,
         "many": false
       }
     }
   }

5. Click Create to save the blueprint.

Existing blueprint

Add a repository relation

If you already created techDoc from Manage and surface technical documentation, keep that blueprint. Add a relation to githubRepository so wiki pages can attach to the repository that holds docs/wiki/.

1. Go to the Data model page and open Tech Doc.

2. Click the {...} Edit JSON button.

3. Add this relation. If a service relation is required, set "required": false on it. This mapping sets repository and does not set service.

   "repository": {
     "title": "Repository",
     "target": "githubRepository",
     "required": false,
     "many": false
   }

4. Click Save.

Create the wikiRun blueprint

Each backend run upserts one wikiRun entity. The repository is stored as a string, in owner/name form, rather than as a relation.

1. Go to the Data model page.

2. Click + Blueprint.

3. Click the {...} Edit JSON button.

4. Copy and paste the following JSON configuration:

   Wiki Run blueprint (click to expand)

   {
     "identifier": "wikiRun",
     "title": "Wiki Run",
     "icon": "Book",
     "schema": {
       "properties": {
         "mode": {
           "title": "Mode",
           "type": "string",
           "enum": ["full", "update"]
         },
         "status": {
           "title": "Status",
           "type": "string",
           "enum": ["pr_opened", "no_changes", "rejected", "failed"],
           "enumColors": {
             "pr_opened": "green",
             "no_changes": "blue",
             "rejected": "red",
             "failed": "red"
           }
         },
         "repository": {
           "title": "Repository",
           "type": "string"
         },
         "pullRequestUrl": {
           "title": "Pull request",

           "format": "url"
         },
         "commitRange": {
           "title": "Commit range",

         },
         "runUrl": {

     },
     "mirrorProperties": {},
     "calculationProperties": {},
     "aggregationProperties": {},
     "relations": {}
   }

5. Click Create to save the blueprint.

Set up the wiki backend

This is the part that actually writes the wiki. We will create one repository, give it the keys it needs, and add the workflows. The application repositories you document do not get workflow files, secrets, or variables of their own.

Create the backend repository

Create a repository named wiki-backend in your GitHub organization. Every wiki, the first one and the hourly refreshes, runs from here.

Create GitHub access tokens

Claude reads the repository it is documenting, and repository files can contain anything, including text that tries to misuse a credential. So we use two fine-grained personal access tokens, and only one of them is ever shown to Claude.

Create both under GitHub > Settings > Developer settings > Fine-grained personal access tokens.

Token	Secret name	Repository access	Permissions
Checkout, push, and pull requests	PORT_GITHUB_TOKEN	Every enrolled target repository. Leave wiki-backend off this token.	Contents: Read and write. Pull requests: Read and write. Issues: Read and write (the workflow creates the docs:wiki label). Metadata: Read-only.
Hourly sync	WIKI_SYNC_TOKEN	wiki-backend and every enrolled target repository.	Actions: Read and write. Contents: Read. Pull requests: Read. Metadata: Read-only.

What Claude is allowed to touch

Claude receives PORT_GITHUB_TOKEN. Keep that token on the repositories you want documented. Leave wiki-backend, and the rest of the organization, off it. The hourly token never goes to Claude.

Add actions secrets

In wiki-backend, open Settings > Secrets and variables > Actions and click New repository secret for each row below.

Name	What to paste
ANTHROPIC_API_KEY	Your Anthropic API key. The writing step uses it.
PORT_GITHUB_TOKEN	The token that checks out the target repository and opens the pull request.
PORT_CLIENT_ID	Your Port client ID.
PORT_CLIENT_SECRET	Your Port client secret.
WIKI_SYNC_TOKEN	The token the hourly check uses to read repositories and start a refresh.

You do not need GitHub variables. The skill's repository and pinned commit live in the workflow file, so changing them means a reviewed pull request.

Backend folder structure

When the steps below are done, wiki-backend contains these four files. Each following section fills one in.

wiki-backend/
├── repos.yaml
├── scripts/
│   └── wiki_sync.py
└── .github/workflows/
    ├── wiki-backend.yaml
    └── wiki-sync.yaml

Configure enrolled repositories

repos.yaml is the list the hourly check watches. A repository joins that list only after three things are true: it is listed here, both tokens can see it, and someone has merged its first wiki.

repos.yaml (click to expand)

# Repositories the wiki sync keeps up to date.
#
# To enroll a repository:
#   1. Add an entry below and merge the change.
#   2. Add the repository to both tokens.
#   3. In Port, run "Generate wiki" in full mode, then review and merge the pull request.
repos:
  - name: <YOUR_GITHUB_ORG>/payments-service
  - name: <YOUR_GITHUB_ORG>/inventory-service

Pin the deepwiki skill

The deepwiki skill is what powers the wiki. Claude loads it as a skill, reads the repository, and follows its steps to write the pages.

We keep the skill on one reviewed commit, 887304e68ff3711a964bcb4b3f33e47ad53c4405 (version 1.0.4), so generation stays on a version you have already looked at. When a newer commit is stable, or you have reviewed it and you are happy with it, update that commit in a pull request.

Add the generation workflow

In wiki-backend, create .github/workflows/wiki-backend.yaml and paste the workflow below. This is the file Port runs when someone clicks Generate wiki, and the same file the hourly check runs when the code has moved on.

wiki-backend.yaml (click to expand)

A single wiki is capped at an hour, so a stuck run cannot keep spending. If someone starts a second wiki for the same repository while the first is still going, it waits its turn.

Refresh the wiki automatically

After the first wiki is merged, this workflow is what stops it from drifting. About once an hour it looks at each repository on the list. When real code has landed since the docs were last updated, it asks Claude to refresh the affected pages and open another pull request.

Set up wiki resources in Port

The backend writes the pages. In Port they live in the context lake, where people find them with Port AI and the wiki dashboard, and where they ask for a new wiki.

Ingest the pages

Each markdown page under the wiki becomes a tech doc, linked to the repository it came from. You add this mapping once. After that, a newly enrolled repository shows up on its own once its wiki is merged.

1. Go to the connectors page and open your GitHub integration.

2. Open the Mapping tab.

3. Click the {...} Edit YAML button.

4. Add the following entry to the resources list:

   Wiki page mapping (click to expand)

   - kind: file
     selector:
       query: >-
         (.path | startswith("docs/wiki/"))
         and ((.path | contains("/_context/")) | not)
         and ((.path | contains("/_reports/")) | not)
       files:
         - path: 'docs/wiki/**/*.md'
           skipParsing: true
     port:
       entity:
         mappings:
           identifier: '.repository.name + "-wiki-" + (.path | sub("^docs/wiki/"; "") | gsub("/"; "-") | gsub("[.]"; "-"))'
           title: '.path | split("/") | .[-1] | sub("[.]md$"; "") | sub("^[0-9]+_"; "") | gsub("_"; " ")'
           blueprint: '"techDoc"'
           properties:
             content: .content
             filePath: .path
             folderPath: .path | split("/") | .[:-1] | join("/")
             url: '.repository.html_url + "/blob/" + .repository.default_branch + "/" + .path'
             lastUpdated: >-
               (try (.commit.commit.committer.date // .commit.commit.author.date //
               .commit.committer.date // .commit.author.date) catch null)
               // .repository.pushed_at // .repository.updated_at
           relations:
             repository: .repository.name

5. Click Save & Resync.

Match the repository identifier

The repository relation has to point at the same identifier your githubRepository entities already use. Port's default GitHub mapping uses the repository name on its own. If your identifiers look like owner/name, change the relation value to .repository.owner.login + "/" + .repository.name.

If you already ingest **/*.md into techDoc, add and (.path | startswith("docs/wiki/") | not) to that older block. Otherwise every wiki page shows up twice.

Add the TechDocs plugin

The plugin is how someone reads the wiki, with a folder tree instead of a flat list of entities. Install it here, then add it to the wiki dashboard in the next section, where it lists every tech doc in the catalog.

Image support

The TechDocs plugin does not render images embedded in markdown.

Plugins library

Install the TechDocs plugin

1. Click on your profile picture and select Settings.
2. Open Plugins and click Library.
3. Find TechDocs and click Add plugin.

Plugin repository

1. Clone Port's plugin repository.

2. Enter the techdocs folder.

3. Build the plugin and upload it with the Port plugins CLI:

   npm install
   npm run build
   port-plugins upload \
   --file dist/index.html \
   --identifier techdocs-port-plugin \
   --title "TechDocs Viewer" \
   --params "$(cat upload-params.json)" \
   --upsert

Once pages are in the catalog, they also show up in global search and in Port AI. Manage and surface technical documentation covers asking questions against them.

Create a documentation dashboard

This is where people read the wikis, and see which generations are still waiting on a review.

1. Go to the catalog page in Port.
2. In the left sidebar, click +, then New dashboard.
3. Name the dashboard Technical documentation, choose the Book icon, and add a short description such as "Wikis generated for our repositories".
4. Click Create.

Add the TechDocs plugin to this dashboard. It lists every tech doc in the catalog.

1. Click + Widget, select Custom, and choose TechDocs Viewer.

2. Title it TechDocs Viewer.

3. Select TechDoc as the TechDoc blueprint and GitHub Repository as the Tech Doc related blueprint.

4. Click Create.

   

Then add a table of recent generations, so you can see whether the hourly check is keeping up and which pull requests are still open.

1. Click + Widget and select Table.

2. Title it Wiki runs and choose the Wiki Run blueprint.

3. Click Save.

4. Show the repository, mode, status, pull request, and total cost columns, and sort by creation time so the newest run is first. See table customization.

   

Create the generate wiki workflow

This is the button users click in Port. It asks which repository, and whether to write the whole wiki or refresh part of it, then asks GitHub to start the backend workflow. They can also run it as a day-2 action on the repository, which selects that repository for them.

1. Go to the workflows page.
2. Click + Workflow.
3. For Name, enter Generate wiki, then click Confirm.
4. Click the {...} button and paste the JSON below.
5. Replace <YOUR_GITHUB_OCEAN_INTEGRATION_ID> and <YOUR_GITHUB_ORG>.
6. Click Apply changes.

The installation ID is on the GitHub integration's Manage panel. See finding your installation ID.

Repository value sent to GitHub

The backend expects owner/name. Port's default githubRepository identifier is the repository name only, so the template prefixes your organization. Open one repository entity and check its identifier. If the identifier is already owner/name, pass .outputs.trigger.repository on its own and drop the organization prefix.

Let's test the workflow

Run Generate wiki for one repository, merge the pull request it opens, and confirm the pages show up on the documentation dashboard.

1. Go to the workflows page and click Generate wiki.

2. Select the repository, set Mode to full, and click Generate.

   

3. When the run finishes, open the Technical documentation dashboard and find the new row in Wiki runs. The pull request link is on that row.

4. Merge the pull request.

   

5. After the GitHub integration syncs, the wiki pages appear in the TechDocs plugin on the same dashboard.
