 ## How to use
-The usage of Enumer is the same as Stringer, so you can refer to the [Stringer docs](https://godoc.org/golang.org/x/tools/cmd/stringer)
+
-for more information.
+For a module-aware repo with `enumer` in the `go.mod` file, generation can be called by adding the following to a `.go` source file:
+
+```golang
+//go:generate go run git.internal/re/enumer -type=YOURTYPE
+```
 
 There are four boolean flags: `json`, `text`, `yaml` and `sql`. You can use any combination of them (i.e. `enumer -type=Pill -json -text`),
 
-
 For enum string representation transformation the `transform` and `trimprefix` flags
 were added (i.e. `enumer -type=MyType -json -transform=snake`).
-Possible transform values are `snake` and `kebab` for transformation to snake_case and kebab-case accordingly.
+Possible transform values are listed above in the [transformers](#transformers) section.
 The default value for `transform` flag is `noop` which means no transformation will be performed.
 
 If a prefix is provided via the `trimprefix` flag, it will be trimmed from the start of each name (before
 it is transformed). If a name doesn't have the prefix it will be passed unchanged.
 
+If a prefix is provided via the `addprefix` flag, it will be added to the start of each name (after trimming and after transforming).
+
+The boolean flag `values` will additionally create an alternative string values method `Values() []string` to fullfill the `EnumValues` interface of [ent](https://entgo.io/docs/schema-fields/#enum-fields).
