The installation of StickyTheme is super straight forward. Just follow the easy steps below (or check out this installation manual here):

a) Get the theme files

• → StickyTheme (PayPal)
• → StickyTheme (credit card) - soon

b) Log into your Tumblr account…

…and go to the → theme settings page where you’ll find the “Edit HTML” button. Click it and paste the stickytheme.html (the file you downloaded) contents into the editor.

Tutorial: To get the contents of stickytheme.html you need to open the file with a text editor, copy it all and paste it into the earlier opened Tumblr sidebar (if you are using TextEdit for Mac, here’s how you do that.)

c) Click “Update preview”…

…and then “Save”. In all likelyhood you will have to go back to your dashboard and return to the theme settings page to see the real StickyTheme. 

d) Yay! It’s time to personalize…

…your StickyTheme to your needs (check → theme features and → theme layouts). 

a) What is StickyTheme?

StickyTheme is a minimalist yet very flexible design for Tumblr. You can completely alter the theme to reflect your needs and wants. That's why there are a few layout options you can choose to start from. With a few clicks in your theme settings you can customize them to look just the way you want it to.

This Tumblr theme is good at making your content stand out. See more about what it does in the Features section.

b) Where can I get this theme?

You can get this theme here.

c) Feature “X” or “Y” doesn’t work!

You have probably chosen or forgotten to untick a feature that defines an interfering theme property like “Navbar Fixed To Top” AND “Navbar Fixed To Bottom”.

d) I have uploaded a custom icon but it looks weird?

Make sure your custom icon fits within an image of 48px x 48px or else it will distort your beautiful icon a little and render it not-so-beautiful.

e) How can I translate “newsletter” or “XYZ”?

Most things in this theme translate into the Tumblr supported languages automatically. There might be some strings that are not that automattic or that you may want to change. In that case go into your theme settings and browse to “customize your blog”. There you’ll find a button which says Edit HTML. Click it and search for the phrase you would like to translate. Make sure it actually is the right string, translate, preview and save. Boom, your done!

f) Instagram activation

In order to get your latest Instagram images displayed on your blog you need to authenticate through Instagram. But don't worry, we'll have you set up in less than a minute. Just follow these steps:

You need to get something called the Instagram Access Token and → add it in your theme settings where it says Instagram Access Token.

Easy, right? → This link will take you there. Sign in and you will be given your Access Token and ready to go.

g) Anything Else?

Yes! I would like to thank those tireless open sourcers without who this theme would not have been possible, so check out Twitter Bootstrap, Paul Irish, Pixelunion, Desandro, @iamrickharris, @oscargodson, Lea Verou, Dan Eden, Jim Ramsden & Paul Bennet.
