 ## Features
 
 * Super tiny (`glibc`-based is `~13.2MB` and `musl`-based is `~12.5MB`)
-* Built from source, including libraries
-* Built `FROM scratch`, see the [Filesystem](#filesystem) section below for an exhaustive list of the image's contents
-* Reduced attack surface (no `bash`, no UNIX tools, no package manager...)
-* Built with exploit mitigations enabled (see [Security](#security))
+* Compiled from source during build time
+* Built `FROM scratch`, see [Filesystem](#filesystem) for an exhaustive list of the image's contents
+* Reduced attack surface (no shell, no UNIX tools, no package manager...)
+* Built with binary exploit mitigations enabled
 
 
 ## Configuration
 
 ### Volumes
 
-- Bind your **configuration file** at `/etc/nginx/nginx.conf`.
+- Bind your **configuration** at `/etc/nginx/nginx.conf`.
 
 
 ## Building
 
-To build the `glibc`-based image:
-
-```bash
-docker build -t nginx:glibc -f glibc/Dockerfile .
-```
-
-To build the `musl`-based image:
-
-```bash
-docker build -t nginx:musl -f musl/Dockerfile .
-```
-
-
-## Security
-
-This image attempts to build a secure NGINX container image.
-
-It does so by the following ways:
-
-- downloading and verifying the source code of NGINX and every library it is built with,
-- packaging the image with only those files required during runtime (see [Filesystem](#filesystem)),
-- by enforcing a series of exploit mitigations (PIE, full RELRO, full SSP, NX and Fortify)
-
-### Verifying the presence of exploit mitigations
-
-To check whether a binary in a container image has those mitigations enabled, use [tests/checksec.sh](https://github.com/ricardbejarano/nginx/blob/master/tests/checksec.sh).
-
-#### Usage
-
-```
-usage: checksec.sh docker_image executable_path
-
-Container-based wrapper for checksec.sh.
-Requires a running Docker daemon.
-
-Example:
-
-  $ checksec.sh ricardbejarano/nginx:glibc /nginx
-
-  Extracts the '/nginx' binary from the 'ricardbejarano/nginx:glibc' image,
-  downloads checksec (github.com/slimm609/checksec.sh) and runs it on the
-  binary.
-  Everything runs inside containers.
-```
-
-#### Example:
-
-Testing the `/nginx` binary in `ricardbejarano/nginx:glibc`:
-
-```
-$ bash tests/checksec.sh ricardbejarano/nginx:glibc /nginx
-Downloading ricardbejarano/nginx:glibc...Done!
-Extracting ricardbejarano/nginx:glibc:/nginx...Done!
-Downloading checksec.sh...Done!
-Running checksec.sh:
-RELRO        STACK CANARY   NX           PIE           RPATH      RUNPATH      Symbols         FORTIFY   Fortified   Fortifiable   FILE
-Full RELRO   Canary found   NX enabled   PIE enabled   No RPATH   No RUNPATH   11570 Symbols   Yes       0           34            /tmp/.checksec-ui8eKi3Q
-Cleaning up...Done!
-```
-
-This wrapper script works with any binary in a container image. Feel free to use it with any other image.
-
-Other examples:
-
-- `bash tests/checksec.sh debian /bin/bash`
-- `bash tests/checksec.sh alpine /bin/sh`
-- `bash tests/checksec.sh nginx /usr/sbin/nginx`
+- To build the `glibc`-based image: `$ docker build -t nginx:glibc -f glibc/Dockerfile .`
+- To build the `musl`-based image: `$ docker build -t nginx:musl -f musl/Dockerfile .`
