+# Wiki Git Workflow (Gitea)
+
+Use this workflow to edit the project wiki locally and push changes to Gitea without using the web editor.
+
+Wiki remote:
+
+`https://gitea.innovativedevsolutions.org/stan44/Project_Journal-Python.wiki.git`
+
+## One-time setup
+
+```powershell
+Set-Location E:\stansshit\Project_Journal
+git clone https://gitea.innovativedevsolutions.org/stan44/Project_Journal-Python.wiki.git wiki
+Set-Location .\wiki
+git config user.name "Your Name"
+git config user.email "you@example.com"
+```
+
+## Daily update flow
+
+```powershell
+Set-Location E:\stansshit\Project_Journal\wiki
+git pull --ff-only
+```
+
+Edit or add `*.md` pages, then:
+
+```powershell
+Set-Location E:\stansshit\Project_Journal\wiki
+git add .
+git commit -m "wiki: update migration docs"
+git push
+```
+
+## Quick check
+
+```powershell
+Set-Location E:\stansshit\Project_Journal\wiki
+git status
+git log --oneline -n 5
+```
+
+## Notes
+
+- Wiki pages are normal Markdown files in this separate wiki Git repo.
+- Use short, scoped commits (one topic per commit).
+- If `git push` fails due to auth, re-run with your preferred credential method (token/credential manager).
