+Updating Duktape
+================
+
+1. Fetch the [latest release](http://duktape.org/download.html) archive.
+
+2. Extract it somewhere.
+
+3. That extracts to a `duktape-[VERSION]` directory.
+
+4. We need to tell duktape about our `duk_custom.h` header:
+
+ 1. Change into the `duktape-[VERSION]` directory.
+
+ 2. Run the following command:
+
+ python2 tools/configure.py \
+ --output-directory /tmp/output \
+ --source-directory src-input \
+ --config-metadata config \
+ --fixup-line '#include "duk_custom.h"'
+
+ 3. This generates a suitable set of duktape
+ sources in `/tmp/output`
+
+5. Replace the `duktape.c`, `duktape.h` and
+ `duk_config.h` files in the netsurf source
+ tree (in `content/handlers/javascript/duktape`)
+ with those generated in `/tmp/output`.
