You can execute the first line to import the wiki,
Local srv net!9p.io!wiki wiki /mnt/wiki
and the third line to bring up the browser - though if you don't use the latest version of acme you'll need to run a new instance of Acme because Local doesn't import into the current namespace
Wiki /mnt/wiki/
The browser should be fairly intuitive given familiarity with acme.
To follow wiki links, right-click page names inside square brackets: sandbox.
You can edit any wiki page, then click Put in the acme tag to save your changes to the server.
To add a new wiki page, click New in the acme tag, then type the title in the first line of the resulting window, followed by a newline, then your content for the new page. Use Wiki syntax for formatting.
You may need to add the following line to /lib/ndb/common to define the default wiki file service TCP port:
tcp=wiki port=17035
though this is defined in the distributed /lib/ndb/common as of Sept. 07.
