 ## Install:
 
-If installing as user (without venv), Make sure that `~/.local/bin` is in `PATH`.
+If installing as user (without venv), make sure that `~/.local/bin` is in `PATH`.
+
+#### Windows/MSYS2:
+
+> Install [MSYS2 and the MMGen Wallet dependencies][8], skipping installation of
+> scrypt, libsecp256k1 and the wallet itself if desired.
+>
+> Install some additional dependencies:
+> ```bash
+> $ pacman -S mingw-w64-ucrt-x86_64-python-pandas
+> $ python3 -m pip install requests-futures
+> $ python3 -m pip install --no-deps yahooquery
+> ```
+
+#### Linux, macOS:
+
+> Install some [required packages][7] with your package manager and pip.
 
 ### Stable version:
 
-First, install the [required MMGen packages][7] for your Linux distribution:
-
-Then,
-
-	$ python3 -m pip install --upgrade mmgen-node-tools
+```bash
+$ python3 -m pip install --upgrade mmgen-node-tools

 ### Development version:
 
-First, install the latest development version of [MMGen][6].

 ## Test:
 
-*NOTE: the tests require that the MMGen and MMGen Node Tools repositories be
+*NOTE: the tests require that the MMGen Wallet and MMGen Node Tools repositories be
 located in the same directory.*
 
+#### Windows/MSYS2:
+
+> *Tested only on NTFS – with ReFS your mileage may vary*
+>
+> Turn on Developer Mode to enable symlinks:
+> ```
+> Settings -> Update & Security -> For developers -> Developer Mode: On

+blocks Tor behind a Captcha wall, so a Tor proxy cannot be used directly.
+If you’re concerned about privacy, connect via a VPN, or better yet, VPN over
+Tor.  Then set up an HTTP proxy (e.g. Privoxy) on the VPN’ed host and set the
+‘proxy’ option in the config file or --proxy on the command line accordingly.
+Or run the script directly on the VPN’ed host with ’proxy’ or --proxy set to
+the null string.
 
 Alternatively, you may download the JSON source data in a Tor-proxied browser
-from ‘{api_url}’, save it as ‘ticker.json’ in your
-configured cache directory, and run the script with the --cached-data option.
+from {cc.api_url}, save it as ‘ticker.json’ in your
+configured cache directory and run the script with the --cached-data option.
+
+Financial data is obtained from {fi.desc}, which currently allows Tor.
 
 
                              RATE LIMITING NOTE
 
-To protect user privacy, all filtering and processing of data is performed
-client side so that the remote server does not know which assets are being
-examined.  This means that data for ALL available assets (currently over 4000)
-is fetched with each invocation of the script.  A rate limit of {L} seconds
-between calls is thus imposed to prevent abuse of the remote server.  When the
---btc option is in effect, this limit is reduced to {B} seconds.  To bypass the
-rate limit entirely, use --cached-data.
+To protect user privacy, filtering and processing of cryptocurrency data is
+performed client side so that the remote server does not know which assets
+are being examined.  This is done by fetching data for the top {al} crypto
+assets by market cap (configurable via the --asset-limit option) with each
+invocation of the script.  A rate limit of {cc.ratelimit} seconds between calls is thus
+imposed to prevent abuse of the remote server.  When the --btc option is in
+effect, this limit is reduced to {cc.btc_ratelimit} seconds.  To bypass the rate limit
+entirely, use --cached-data.
+
+Note that financial data obtained from {fi.api_host} is filtered in the
+request, which has privacy implications.  The rate limit for financial data
+is {fi.ratelimit} seconds.
