+# Segfautilities
+Web utilities for Project Segfault
+
+## What does it do?
+For now it powers our contact form. In the future we will expand our APIs so you can do more cool things.
+
+## Setup
+
+### Docker: 
+```
+docker run -d --restart=always -p 6893:6893 --name segfautilities projectsegfault/segfautilities:latest -e HCAPTCHA_SITE_KEY='YOURSITEKEY' -e HCAPTCHA_SECRET_KEY='YOURSECRETKEY' -e SEGFAUTILITIES_WEBHOOK_URL='YOURWEBHOOKURL'
+```
+
+We recommend using Docker as it provides better security (we suck in security, so that's why) and we are constantly updating Segfautilities. Docker makes it easy to update the program.
+
+If you're using Portainer, you should know how to add Segfautilities.
+
+### Manual (recommended for development)
+```
+git clone https://github.com/ProjectSegfault/segfautilities
+cd segfautilities/
+# You need to add the environment HCAPTCHA_SITE_KEY, HCAPTCHA_SECRET_KEY, SEGFAUTILITIES_WEBHOOK_URL and SEGFAUTILITIES_PORT.
+go run main.go # Run this when you've done above!
+```
+#### NixOS
+``` 
+git clone https://github.com/ProjectSegfault/segfautilities
+cd segfautilities/ 
+nix-shell # Avoid installing Go and setting up the web port, by just running a nix shell
+# You still need the environment variables HCAPTCHA_SITE_KEY, HCAPTCHA_SECRET_KEY and SEGFAUTILITIES_WEBHOOK_URL though!
+go run main.go # I wonder if this is good practice or not. If this isn't good practice, make a GitHub issue please.
+```
