-# docFxWebAppRefresh
-DocFx .net core web app build middleware. Rebuilds docFx assets when files are changed in a web app.
+# ElCamino.DocFx.WebAppRefresh
+DocFx build middleware that allows you to setup a .net core web app project and adds a file watcher to your content files. When you change a content file, such as markdown, css, etc, the middleware automatically starts a docFx build in the background regenerating the target html files.
+
+**This library should be configured for local development only as shown below!**
+1. Create a new .net core web application 'Empty' project
+```
+dotnet new web
+```
+or 
+
+Use Visual Studio new project, web application, Empty.
+
+2. Use the nuget package manager to install **docfx.console**
+```
+dotnet add package docfx.console 
+``` 
+3. **Build** the project (this will generate all of the docfx files)
+4. Rename the **_site** folder to **wwwroot**.
+5. Edit the *.gitignore* file, remove **_site**, add **wwwroot** and **log.txt**
+```
+wwwroot
+log.txt
+```
+6. Edit the *docfx.json*, rename **_site** and replace with **wwwroot**
+```json
+{...
+    "dest": "wwwroot",
+...
+}
+```
+7. Use the nuget package manager to install **ElCamino.DocFx.WebAppRefresh**
+```
+dotnet add package ElCamino.DocFx.WebAppRefresh 
+```
+8. Edit the Startup.cs
+```c#
+public class Startup
+{
+    ...
+    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
+    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
+    {
+        if (env.IsDevelopment())
+        {
+            app.UseDeveloperExceptionPage();
+            // only use in development, not for production
+            app.UseDocFxBuildRefresh(env.ContentRootPath, env.WebRootPath);
+        }
+        app.UseDefaultFiles();
+
+        app.UseStaticFiles();
+    }
+...
+```
+9. Debug the web application. Change a content file (markdown, css, etc) and watch the debug output for the docFx build output and refresh the page to see your changes.
