+     zones, as well as utilities to compose new ones. Tailors are tightly 
+     integrated with the 'tidymodels' framework.

 ## Installation
 
@@ -32,3 +38,60 @@ You can install the development version of tailor like so:
 ``` r
 pak::pak("tidymodels/tailor")
 ```
+
+## Example
+
+```{r}
+library(tailor)
+```
+
+The `two_class_example` dataset from modeldata gives the true value of an outcome variable `truth` as well as predicted probabilities (`Class1` and `Class2`). The hard class predictions, in `predicted`, are `"Class1"` if the probability assigned to `"Class1"` is above `.5`, and `"Class2"` otherwise.
+
+```{r}
+library(dplyr)
+library(modeldata)
+
+head(two_class_example)
+```
+
+The model predicts `"Class1"` more often than it does `"Class2"`.
+
+```{r}
+two_class_example %>% count(predicted)
+```
+
+If we wanted the model to predict `"Class2"` more often, we could increase the probability threshold assigned to `"Class1"` above which the hard class prediction will be `"Class1"`. In the tailor package, this adjustment is implemented in `adjust_probability_threshold()`, which can be situated in a tailor object.
+
+```{r}
+post_obj <-
+  tailor() %>%
+  adjust_probability_threshold(threshold = .9)
+
+post_obj
+```
+
+tailors must be fitted before they can predict on new data. For adjustments like `adjust_probability_threshold()`, there's no training that actually happens at the `fit()` step besides recording the name and type of relevant variables. For other adjustments, like probability calibration with `adjust_probability_calibration()`, parameters are actually estimated at the `fit()` step and separate data should be used to train the postprocessor and evaluate its performance.
+
+In this case, though, we can `fit()` on the whole dataset. The resulting object is still a tailor, but is now flagged as trained.
+
+```{r}
+post_res <- fit(
+  post_obj,
+  two_class_example,
+  outcome = c(truth),
+  estimate = c(predicted),
+  probabilities = c(Class1, Class2)
+)
+
+post_res
+```
+
+When used with a model [workflow](https://workflows.tidymodels.org) via `add_tailor()`, the arguments to `fit()` a tailor will be set automatically (in addition to the data splitting needed for postprocessors that require training).
+
+Now, when passed new data, the trained tailor will determine the outputted class based on whether the probability assigned to the level `"Class1"` is above `.9`, resulting in more predictions of `"Class2"` than before.
+
+```{r}
+predict(post_res, two_class_example) %>% count(predicted)
+```
+
+Tailors compose adjustments; when several `adjust_*()` functions are called iteratively, tailors will apply them in order at `fit()` and `predict()` time.
