We will be using TiddlyWiki for delivering the lab content in INFO202. You saw this in INFO201 so the following is a quick refresher:

• When you have completed a section you can close it with the <> button at the top right of each section.

• You can save the current state of your progress by clicking the <> button on the side bar to the right. This will change the URL to include the state which you can then bookmark. If you open the bookmark the page will reappear in the exact state that you left it in.

• You can reset back to the original state using the <> button on the side bar on the right. This will close all open sections, so you will lose your progress.

• You can reopen a closed section by clicking its link in the 'Contents' section for that lab, or use the 'Contents' tab in the side bar.

• There is a search box in the side bar on the right that can search the entire document.

• If you want a printed copy of this document, first reset the document back to its default state by clicking the <> home button, then click the link for the lab that you want to print, then click the <

  > button to open all of the sections, and finally click the <> button on the side bar on the right to print the document in is current state.

• You can show and hide the side bar to make more room for the content using the <> button at the very top right of the document.

• If you prefer a dark theme then click the <> button on the side bar. We try to make the document fully viewable in both the dark and light themes, so if you notice that something is broken in the dark theme then let us know.

  You can click the <> button to switch back to the light theme.

• You can download a copy of this document for offline use using the <> button on the side bar on the right. Note that this is the only proper way to save the document. Using the browser's 'save page' feature will likely result in a corrupted document. The file is completely self-contained, so the single HTML file that is downloaded contains the entire document at this point in time. You should be able to open the downloaded file in your browser by double clicking it in your file browser.

  We will add more to this document as the semester progresses, so stick to the online version of the document unless you do need to work offline.
