+## (Advanced) Running on a subdomain
+
+It is possible to run microblogpub on a subdomain (`sub.domain.tld`) while being reachable from the root root domain (`domain.tld`) using the `name@domain.tld` handle.
+
+This requires forwarding/proxying requests from the root domain to the subdomain, for example using NGINX:
+
+```nginx
+location /.well-known/webfinger {
+  add_header Access-Control-Allow-Origin '*';
+  return 301 https://sub.domain.tld$request_uri;
+}
+```
+
+And updating `data/profile.toml` to specify the root domain as the webfinger domain:
+
+```toml
+webfinger_domain = "domain.tld"
+```
+
+Once configured correctly, people will be able to follow you using `name@domain.tld`, while using `sub.domain.tld` for the web interface.
+
+
+## (Advanced) Running from subpath
+
+It is possible to configure microblogpub to run from subpath.
+To achieve this, do the following configuration _between_ config and start steps.
+i.e. _after_ you run `make config` or `poetry run inv configuration-wizard`,
+but _before_ you run `docker compose up` or `poetry run supervisord`.
+Changing this settings on an instance which has some posts or was seen by other instances will likely break links to these posts or federation (i.e. links to your instance, posts and profile from other instances).
+
+The following steps will explain how to configure instance to be available at `https://example.com/subdir`.
+Change them to your actual domain and subdir.
+
+* Edit `data/profile.toml` file, add this line:
+
+		id = "https://example.com/subdir"
+
+* Edit `misc/*-supervisord.conf` file which is relevant to you (it depends on how you start microblogpub - if in doubt, do the same change in all of them) - in `[program:uvicorn]` section, in the line which starts with `command`, add this argument at the very end: ` --root-path /subdir`
+
+Above two steps are enough to configure microblogpub.
+Next, you also need to configure reverse proxy.
+It might slightly differ if you plan to have other services running on the same domain, but for [NGINX config shown above](#reverse-proxy), the following changes are enough:
+
+* Add subdir to location, so location block starts like this:
+
+		location /subdir {
+
+* Add `/` at the end of `proxy_pass` directive, like this:
+
+		proxy_pass http://localhost:8000/;
+
+These two changes will instruct NGINX that requests sent to `https://example.com/subdir/...` should be forwarded to `http://localhost:8000/...`.
+
+* Inside `server` block, add redirects for well-known URLs (add these lines after `client_max_body_size`, remember to replace `subdir` with your actual subdir!):
+
+		location /.well-known/webfinger { return 301 /subdir$request_uri; }
+		location /.well-known/nodeinfo  { return 301 /subdir$request_uri; }
+		location /.well-known/oauth-authorization-server  { return 301 /subdir$request_uri; }
+
+* Optionally, [check robots.txt from a running microblogpub instance](https://microblog.pub/robots.txt) and integrate it into robots.txt file in the root of your server - remember to prepend `subdir` to URLs, so for example `Disallow: /admin` becomes `Disallow: /subdir/admin`.

+You will need to [recompile CSS](#recompiling-css-files) after doing any CSS changes (for actual css files to be updates) and restart microblog.pub (for css link in HTML documents to be updated with a new checksum - otherwise, browsers that downloaded old CSS will keep using it).
+
+#### Custom favicon
+
+By default, microblog.pub favicon is a square of `$primary-color` CSS color (see above section on how to redefine CSS colors).
+You can change it to any icon you like - just save a desired file as `data/favicon.ico`.
+After that, run the "[recompile CSS](#recompiling-css-files)" task to copy it to `app/static/favicon.ico`.
+
+#### Custom templates
+
+If you'd like to customize your instance's theme beyond CSS, you can modify the app's HTML by placing templates in `data/templates` which overwrite the defaults in `app/templates`.
+
+Templates are written using [Jinja](https://jinja.palletsprojects.com/en/latest/templates/) templating language.
+Moreover, `utils.html` has scoped blocks around the body of every macro.
+This allows macros to be overridden individually in `data/templates/utils.html`, without copying the whole file.
+For example, to only override the display of a specific actor's name/icon, you can create `data/templates/utils.html` file with following content:
+
+```jinja
+{% extends "app/utils.html" %}
+
+{% block display_actor %}
+	{% if actor.ap_id == "https://me.example.com" %}
+		<!-- custom actor display -->
+	{% else %}
+		{{ super() }}
+	{% endif %}
+{% endblock %}
+```
+
+#### Custom Content Security Policy (CSP)
+
+You can override the default Content Security Policy by adding a line in `data/profile.toml`:
+
+```toml
+custom_content_security_policy = "default-src 'self'; style-src 'self' 'sha256-{HIGHLIGHT_CSS_HASH}'; frame-ancestors 'none'; base-uri 'self'; form-action 'self';"
+```
+
+This example will output the default CSP, note that `{HIGHLIGHT_CSS_HASH}` will be dynamically replaced by the correct value (the hash of the CSS needed for syntax highlighting).
