+# Scan Server
+
+Scan server is a Free to use alternative to many expensive solutions out there that allow scanning documents from Web applications.
+
+## Project Structure
+
+There are two projects:
+1. ScanServer: Compiles into a .exe that can be run a standalone app or as a service
+2. ScanServerInstaller: Create an MSI to make easier to download and install as Windows Service (Runs by default on http://localhost:5000).
+
+## How to use
+
+Just run/install the app.
+List the devices on: http://localhost:5000/api/scanners
+
+
+## Getting started
+
+To build this project:
+
+```ps
+cd .\ScanServer
+rm -r .\bin\
+dotnet clean
+dotnet publish ScanServer.csproj -c Release
+cd ..\ScanServerInstaller
+rm -r .\bin\
+dotnet clean
+dotnet build -c Release
+```
+
+
+## Uninstall:
+
+To uninstall start a command line as administrator and run:
+
+```cmd
+sc stop ScanServer
+sc delete ScanServer
+```
+
+Then delete the install folder.
+
+# Naps2
+
+A huge thank you to @cyanfish and it's [NAPS2 SDK Project](https://github.com/cyanfish/naps2/) without whom/which building this would have taken a lot of time.
+If you want to donate, please donate to him using this [link](https://www.naps2.com/donate?src=scan-server)
+
+# TODO
+Find a way to change the default port in the service either:
+1. by configuring the service in the installer
+2. Building the app with another default port while allowing --urls to work.
