 The capfile will be output in the `./bin` directory, along with the `.class`
 files (which can be used with jCardSim).
 
+You can also download pre-built capfiles from the
+[releases page](https://github.com/arekinath/PivApplet/releases) here on GitHub.
+
 The applet can be configured to suit different cards or needs by adjusting
 the feature flags in `build.xml` before running `ant`.
 
 Currently available feature flags:
 
 |===
-|`PIV_SUPPORT_RSA`        | Enable RSA support
-|`PIV_SUPPORT_EC`         | Enable ECDSA and ECDH support
-|`PIV_USE_EC_PRECOMPHASH` | Use JC3.0.4+ API to allow standardised PIV ECDSA (rather than the hash-on-card extension, which will be disabled)
-|`PIV_STRICT_CONTACTLESS` | Block most slots and keys from use over contactless (strictly conform to the PIV spec)
-|`YKPIV_ATTESTATION`      | Enable YubicoPIV-style attestation slot and command
-|`APPLET_USE_RESET_MEM`   | Use `CLEAR_ON_RESET` memory for Cipher and Signature intermediate data. This is needed for cards with low amounts of transient `CLEAR_ON_DESELECT` memory (e.g. J3H145, JC30M48CR)
-|`APPLET_EXTLEN`          | Support for extended APDUs. Some cards have bugs that make this feature malfunction (e.g. ACOSJ)
+|`PIV_SUPPORT_RSA`        | `R` | Enable RSA support
+|`PIV_SUPPORT_EC`         | `E` | Enable ECDSA and ECDH support
+|`PIV_SUPPORT_ECCP384`    | `e` | Enable P-384 support with ECDSA/ECDH
+|`PIV_USE_EC_PRECOMPHASH` | `P` | Use JC3.0.4+ API to allow standardised PIV ECDSA (rather than the hash-on-card extension, which will be disabled)
+|`PIV_STRICT_CONTACTLESS` | `S` | Block most slots and keys from use over contactless (strictly conform to the PIV spec)
+|`YKPIV_ATTESTATION`      | `A` | Enable YubicoPIV-style attestation slot and command
+|`APPLET_EXTLEN`          | `x` | Support for extended APDUs. Some cards have bugs that make this feature malfunction (e.g. ACOSJ)
+|`APPLET_LOW_TRANSIENT`   | `L` | Reduce required transient memory for the applet by shrinking buffers. Reduces maximum certificate size and may impact performance. Cannot be used with `YKPIV_ATTESTATION`.
