### JSP
A JSP tag is also available for easy incorporation into web applications:
```jsp
<%@taglib uri="https://erik.thauvin.net/taglibs/readingtime" prefix="t"%>
<t:readingtime postfix="min read" plural="min read" excludeImages="false" wpm="275">some_text</t:readingtime>
```
None of the attributes are required.
Just drop the jar into your `WEB-INF/lib` directory.
### Gradle
To use with [Gradle](https://gradle.org/), include the following dependency in your [build](https://github.com/ethauvin/readingtime/blob/master/examples/build.gradle.kts) file:
