+# Squiggle.c
+
+
+
+## Why C?
+
+- Because it is fast
+- Because it can be made faster if need be, e.g., with a multi-threading library like OpenMP
+- Because if you can implement something in C, you can implement it anywhere else
+- Because it will last long
+- Because the language is honest
+- Because I enjoy it
+
+## To do list
+
+- [ ] Have some more complicated & realistic example
+- [ ] Add summarization functions, like mean, std, 90% ci (or all c.i.?)
+- [ ] Add README
+ - Schema: a function which takes a sample and manipulates it,
+ - and at the end, an array of samples.
+ - Explain boxes
+ - Explain individual examples
+ - Explain nested functions
+- [ ] Publish online
+
+## Done
+
+- [x] Add example for only one sample
+- [x] Add example for many samples
+- ~~[ ] Add a custom preprocessor to allow simple nested functions that don't rely on local scope?~~
+- [x] Use gcc extension to define functions nested inside main.
+- [x] Chain various mixture functions
+- [x] Add beta distribution
+ - See <https://stats.stackexchange.com/questions/502146/how-does-numpy-generate-samples-from-a-beta-distribution> for a faster method.
+- ~~[-] Use OpenMP for acceleration~~
+- [x] Add function to get sample when given a cdf
+- [x] Don't have a single header file.
+- [x] Structure project a bit better
