-It's a random animal name generator!
+A random animal name generator, forked from
+[`random-animal-name-generator`](https://github.com/adzialocha/random-animal-name-generator).
 
 ```js
-  const generateRandomAnimalName = require('animal-name-generator')
-  const animalName = generateRandomAnimalName()
-  console.log(animalName)
-```
+import { generateRandomName } from 'ranimal'
 
-With funny animal names!
+// In some async context...
+const name = await generateRandomName()

-## Development
+## Differences
 
-Clone the repository and install all dependencies:
+`random-animal-name-generator` hasn't been updated in awhile, so here's a list
+of adjustments:
 
-```
-git clone git@github.com:adzialocha/random-animal-name-generator.git
-cd random-animal-name-generator
-npm install
-npm run test
-```
+### Async by default
+
+The word lists are absolutely massive, with previously upwards of 1700 animals
+and nearing 9000 adjectives. Loading these files is less of a problem in Node,
+but in the browser, we don't want to wait on these files to load with the main
+bundle.
+
+To combat this, the animals list and adjectives lists are loaded via dynamic
+import, so you can rely on your bundler's chunking features to load the lists
+when their necessary. To support this, **`generateRandomName` is now an async
+function.**
+
+In the future, I may consider a synchronous entry, but for now, I think this is
+an improvement.
+
+### Word lists are pre-optimized
+
+Whenever `random-animal-name-generator` is included in your application, it
+sorts the animal and adjective word lists into new objects keyed by their
+starting letter. This is deterministic—the data never changes, and so we don't
+need to rearrange it every time! So, the word lists (moved into the `data`
+folder and converted to JS modules) are now sorted by first letter by default.
+
+### Other stuff
+
+- Removed (probably) all of the animal names that consist of multiple words. The
+  smushed-together animal names were confusing to read.
+- Removed some made-up animal names... Not really sure where the data came from,
+  but I performed Google searches on a number of them and came up with nothing.
+  So, I took them out.
+- Capitalized all words on both word lists, since they're names.
+
+## Untouched Stuff
+
+While the adjectives have been capitalized, there are still quite a number of...
+creative words in the list. It seems like it came from the Scribblenauts wiki,
+which is cool, but it'll take some effort to make sure there are only
+dictionary-acknowledged adjectives in this project.
