+- Blog posts are stored in a SQL database.
+- Image upload.
+- [Docker support](#docker-support).
+- A basic search engine to search through titles and content.
+
+## Building
+
+### Installing ASP.NET Core
+
+#### Linux
+
+I developed this application using Ubuntu 20.04 via WSL2. I folowed the instructions
+listed [here](https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu) to install ASP.NET Core on Ubuntu
+20.04. Please note that other versions of linux are supported by ASP.NET Core, and thus this application will work on
+other linux distros.
+
+#### Windows & MacOS
+
+You can install ASP.NET Core [here](https://dotnet.microsoft.com/en-us/download/dotnet/6.0) and follow the instructions
+to install dotnet and asp.net on your computer.
+
+#### Building the application (binary)
+
+Building the application is trivial. I used the command line to build the application.
+
+```bash
+dotnet build
+```
+
+This will build the application and place binaries in the BlogSite/bin/Debug/net6.0 directory.
+
+#### Running the application
+
+Running the application is also trivial. Just navigate to the BlogSite directory and run the application.
+
+```bash
+cd BlogSite/bin/Debug/net6.0
+dotnet BlogSite.dll
+```
+
+This will create a few files on startup - app.db, posts.db, and a "Media" directory.
+
+#### Adding an admin user
+
+At this present moment, there is two roles - an Admin role which allows users to post, and a default role. To create an
+admin user, first create a user using the website itself (naviage to the login page, create a user there.)
+After this is done, you can add the email that was used for the account to the "Administartors" list in the file
+`appsettings.json`. By default, the user with the email `email@email.com` will be granted administrator rights
+on the next startup of the program. You will need to reboot the application after adding an administrator.
+```json
+...
+"Administrators": [
+      "email@email.com"
+    ]
+...
+```
+#### Docker support
+You can build the application using Docker.
+```bash
+docker build -t blogsite -f BlogSite/Dockerfile .
+```
+After building the image, you can run the application. It is recommended to create
+two directories somewhere for the application to store data - one for the databases, and one for the media.
+#### Creating the directories
+```bash
+mkdir ~/blogsite-media
+mkdir ~/blogsite-db
+```
+
+##### Running the application via docker
+```bash
+docker run -v ~/blogsite-db:/db -v ~/blogsite-media:/app/Media -p 80:80 -d --name blogsite blogsite
+```
+#### Using a prebuilt docker image.
+Each commit to the master branch will have a docker image automatically created (rolling release style).
+You can use the current image by running the following command.
+```bash
+docker pull gcpease/blogsite:latest
+```
+After running this command, you can run the application.
+```bash
+ docker run -v ~/blogsite-db:/db -v ~/blogsite-media:/app/Media -dp 7160:80 --name blogsite gcpease/blogsite:latest
+ ```
+#### Updating the prebuild docker image.
+To update the docker image, run the following commands.
+```bash
+docker stop blogsite
+docker rm blogsite
+docker pull gcpease/blogsite:latest
+docker run -v ~/blogsite-db:/db -v ~/blogsite-media:/app/Media -dp 7160:80 --name blogsite gcpease/blogsite:latest
+```
+## Future Features
+- Better role management.
+- A draft system.
+- Comments.
+- Tagging.
+## Things to work on
+- [ ] XSS prevention
+- [ ] Post content and title sanitization.
+- [ ] A better way to store/render images/media.
+## Background
+
+### Why would I develop another CMS?
+
+If you have been following my development for a few years now, you might have notice dthat I have written a new blogging
+system about once a year. With each iteration, I have added more features and have tinkered with a different language.
+My first CMS originally started out from a static HTML page that was generated by a bash script, which evolved to a
+system that used MySQL and PHP. This system worked, but there were a lot of flaws with using PHP, and flaws within the
+software itself. I decided to write a new system that was more flexible and easier to use, as well as more secure. This
+led to the creation of this CMS which is powered by ASP.NET Core, C#, and Sqlite. This will hopefully be my last
+iteration of a blog system, and I hope to continue to add more features to it. This CMS has proven to be a fun
+challenge, as well as a practical application of knowledge I have gained from classes I have taken.
+
+### Why C#?
+
+I have always been interested in C#, and I have always had a strong interest in ASP.NET Core. I have used C# in the past
+for some school assignments and enjoyed it. I've wanted to learn how to use ASP.NET Core and the MVC architecture for
+quite some time, so this made C# an excellent choice.
