 Frenchman, and say "Oui, il est le git!"

+FEATURES
+
+• Fully customizable templates and stylesheets.
+• Cloning over http(s).
+• Less archaic HTML.
+• Not CGI.
+
 
 INSTALLING
 
 Clone it, 'go build' it.
+
+
+CONFIG
+
+Uses yaml for configuration. Looks for a 'config.yaml' in the current
+directory by default; pass the '--config' flag to point it elsewhere.
+
+Example config.yaml:
+
+    repo:
+      scanPath: /var/www/git
+      readme:
+        - readme
+        - README
+        - readme.md
+        - README.md
+      mainBranch:
+        - master
+        - main
+    dirs:
+      templates: ./templates
+      static: ./static
+    meta:
+      title: git good
+      description: i think it's a skill issue
+    server:
+      name: git.icyphox.sh
+      host: 127.0.0.1
+      port: 5555
+
+These options are fairly self-explanatory, but of note are:
+
+• repo.scanPath: where all your git repos live (or die). legit doesn't
+  traverse subdirs yet.
+• repo.readme: readme files to look for. Markdown isn't rendered.
+• repo.mainBranch: main branch names to look for.
+• server.name: used for go-import meta tags and clone URLs.
+
+
+NOTES
+
+• Run legit behind a TLS terminating proxy like relayd(8) or nginx. 
+• The default head.html template uses my CDN to fetch fonts -- you may
+  or may not want this.
+• Support or cgit-like filters (for readmes etc.) is planned.
+• Pushing over https, while supported, is disabled because auth is a
+  pain. Use ssh.
+• "Private" repos only available over Tailscale is planned.
