 ## Creating Meaning Through Simple Shapes
 
 A minimal logo design is achieved by putting aside all distractions while focusing on legibility, meaning and small details like clear lines, interesting perspective and depth.

 **The letter "r"**, composed of two shapes, is inspired by Albers, a german-born American Bauhaus artist and typographer. An object should be simple, beautiful, functional and accessible for everyone - a statement which applies to ReScript's principles perfectly.

 ### The Structure and Design
 The initial work was mostly about understanding the information architecture, relevant documentation dependencies, and finding all the relevant resources across different websites and blog posts.

 Surprisingly for us, the navigation and sitemap turned out to be the hardest part to figure out. We had to craft long-lived URLs that would work across multiple versions of the Reason compiler and standard library, had to do research about future localization possibilities, understand the guts and limits of different documentation tools such as docusaurus, find a way to enable component based theming, and then put everything in a layout that actually worked across all sorts of devices without being too cluttered or confusing.

 It didn't take long until we realized that we can't just keep the upstream version in its original form, so we started to make adaptations where it made sense. We also accepted new additions from the community, such as explanations about [function signatures on optional arguments](/docs/manual/latest/function#signatures-and-type-annotations) in the Reason manual, or a new decorator overview in the BuckleScript section.

 There were some solutions, but still, Algolia turned out to be the best candidate with its smallest pricing tier. We don't want to rely on the Algolia OSS webscraping API, since it doesn't give us enough control on manipulating the search results, and we need more control if we want to be able to design a custom search experience.

 We did the ground work for our search feature and we will get into more detail as soon as we are able to generate API docs with our aforementioned `doc-tools`. Like with the API docs, we'll first need the doc-tools infrastructure so we can generate indexable data for Algolia as well.
 
 ## Playground
 
 We also invested a lot of time into thinking about the future of the Reason playground from a UX perspective. Our most important goal is to make it possible to switch BuckleScript versions on demand. We also wanted the relevant Reason version to be part of the playground bundle.

 Users should always know what version of BuckleScript / Reason is running when writing and sharing code, and the code written on a playground should be runnable with an equivalent bs-platform setup on a local machine. Right now, `reasonml.github.io/try` uses different refmt.js / playground bundle versions, which makes it really hard to write reproducible code for the same BuckleScript version.
