 ## Why handwritten text recognition for Xournal++?
 
-When moving from physical to digital note taking, one great benefit is searchability. Hence, when starting to use
-digital handwritten notes, those should be searchable as well as to not compromise on the benefits of digital note
-taking. This feature is called [handwritten text recognition](https://en.wikipedia.org/wiki/Handwriting_recognition).
+## Why Handwritten Text Recognition for Xournal++?
 
-The handwritten text recognition feature has been part of many commercial note taking apps for ages.
+A key benefit of digital note-taking is searchability, which digital handwritten notes lack
+without [handwritten text recognition (HTR)](https://en.wikipedia.org/wiki/Handwriting_recognition).
+While many commercial apps offer this feature, no open-source, privacy-focused handwriting
+app does - until now.
 
-However, there exists no such handwritten text recognition feature for any open source handwriting application.
-
-Hence, the goal of Xournal++ HTR is to bring handwritten text recognition to [Xournal++](https://xournalpp.github.io/),
-which is one of the most popular open-source applications to take digital handwritten notes.
-
-### TODO: add the following former section "Project description" to this section here
-
-Taking handwritten notes digitally comes with many benefits but lacks searchability of your notes. Hence, there is a need to make your handwritten notes searchable. This can be achieved with ["handwritten text recognition" (HTR)](https://en.wikipedia.org/wiki/Handwriting_recognition), which is the process of assigning searchable text to written strokes.
-
-While many commercial note taking apps feature great HTR systems to make your notes searchable and there are a number of existing open-source implementations of various algorithms, there is no HTR feature available in an open-source note taking application that is privacy aware and processes your data locally.

-
-Xournal++ HTR strives to bring open-source on-device handwriting recognition to [Xournal++](https://github.com/xournalpp/xournalpp) as it is one of the most adopted open-source note taking apps and thereby HTR can be delivered to the largest possible amount of users.
+The **Xournal++ HTR** project aims to bring on-device handwriting recognition to
+[Xournal++](https://xournalpp.github.io/), a leading open-source note-taking platform.
+This will make handwritten notes searchable while ensuring user privacy through local data
+processing.
