<h2>Explanation</h2>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>As you open the page it tries to connect to the transports, which by default are HTTP and IPFS.</li>
|
||
|
|
<li>These should change to Yellow as they try, and then Green when connected.</li>
|
||
|
|
<li>If it goes Red, it means it failed to connect - e.g. to get an "info" response from HTTP, or to conenct to IPFS.</li>
|
||
|
|
<li>You can edit text, which is happening entirely locally on your machine.</li>
|
||
|
|
<li>When you hit Save, its stored on the connected transports</li>
|
||
|
|
<li>A link to this is put in the Retrieval box</li>
|
||
|
|
<li>You can click on the Retrieve button and it will be retrieved and displayed for editing.</li>
|
||
|
|
<li>You can also paste that link into a different browser.</li>
|
||
|
|
