+#### What is searx?
+Searx is a metasearch engine, inspired by the seeks project.
+It provides basic privacy by mixing your queries with searches on other platforms without storing search data. Queries are made using a POST request on every browser (except chrom[e|ium]). Therefore they show up in neither our logs, nor your url history. In case of Chrom[e|ium] users there is an exception, Searx uses the search bar to perform GET requests. Searx can be added to your browser's search bar; moreover, it can be set as the default search engine. 
+
+#### Features
+- Based on Alpine Linux.
+- Latest code from [asciimoo/searx](https://github.com/asciimoo/searx)
+- A unique secret key is generated when booting the first time.
+
+### Credits
+First of all, thanks to [wonderfall](https://github.com/Wonderfall) for his Dockerfile collection. A lot of this image is based on his image, and was only created because wonderfall discontinued maintainership of all his images.
+
+### Get the image
+You can either build the docker image yourself:
+```bash
+docker build -t docker.jcg.re/searx https://git.jcg.re/jcgruenhage/docker-searx.git
+```
+
+or pull a prebuilt image from my docker registry:
+
+```bash
+docker pull docker.jcg.re/searx
+```
+### Run the container
+Insecure local instance:
+
+```bash
+docker run \
+	--rm \
+	--publish 80:8888 \
+	--env BASE_URL=http://localhost \
+	docker.jcg.re/searx
+```
+
+#### Build-time variables
+- **VERSION** : Searx version
+
+#### Environment variables
+- **IMAGE_PROXY** : enables images proxying *(default : False)*
+- **BASE_URL** : http://domain.tld *(default : False)*
+
+#### Ports
+- **8888** (non-tls, so use a reverse proxy)
