In order to work, HACS needs to retrieve information about repositories using Github's API.
info
Because of the rate limits set by Github, HACS needs to be authenticated by a Personal Access Token, that you can generate using the following steps.
This token will have read-only access to public information, and will only be used by HACS to call Github's API.
Step 1 - Open browser
You are probably looking at this in a browser, so we can probably check this off.
Step 2 - Go to your GitHub "Developer settings"
And then "Personal access tokens." or click here: https://github.com/settings/tokens
Step 3 - Start generation
Click the "Generate new token" button.
If you are asked to login, do so.
Step 4 - Choices
First give it a logical name so that you can recognize it.
Then click the "Generate token" button at the bottom.
You do not need to check any of the boxes.
Step 5 - Copy
Now you see the generated token, this will be the only time you see it, make sure that you copy it manually or by clicking the clipboard icon.
