Installing Jekyll on Windows

Getting Jekyll installed on Windows can be more complicated than on, say, OSX and Ubuntu, but not by much. This outlines the steps I use.

I have similar guidance (plus extra steps for my publishing tools) for OSX written up here.

Why is this tricky?

Because each of the pieces that make Jekyll work is fussy, especially on Windows, which the developers of those pieces rarely use.

//Default WordPress
the_post_thumbnail( 'thumbnail' );     // Thumbnail (150 x 150 hard cropped)
the_post_thumbnail( 'medium' );        // Medium resolution (300 x 300 max height 300px)
the_post_thumbnail( 'medium_large' );  // Medium Large (added in WP 4.4) resolution (768 x 0 infinite height)
the_post_thumbnail( 'large' );         // Large resolution (1024 x 1024 max height 1024px)
the_post_thumbnail( 'full' );          // Full resolution (original size uploaded)
 
//With WooCommerce
the_post_thumbnail( 'shop_thumbnail' ); // Shop thumbnail (180 x 180 hard cropped)
the_post_thumbnail( 'shop_catalog' );   // Shop catalog (300 x 300 hard cropped)
